Best Practices in Managing Microbial Excursions


The European Pharmaceutical Review is hosting a webinar titled ‘Best Practices in Managing Microbial Excursions’ on Tuesday December 3rd.

The brief for the webinar is:

“Learn from industry experts some practices to help better manage the investigation process and how to design processes to minimize unnecessary excursions.

Microbial excursions as a result of an out of specification result from a quality control test can be time consuming and costly. The investigation of the root cause, analysis of the risk to the product, and determination of corrective/preventative actions take hours of manpower and resources and often are caused by issues around personnel practices, keying errors, and incubation errors.”

The webinar is presented by Guenther Gapp, Tim Sandle and David Jones.

How Staph toxin disarms the immune system


Researchers at NYU Langone Medical Center have discovered a new mechanism by which the deadly Staphylococcus aureus bacteria attack and kill off immune cells. Their findings, published today in the journal Cell Host & Microbe, explain a critical survival tactic of a pathogen that causes more skin and heart infections than any other microbe.

Scientists have long known that Staph releases an arsenal of toxins to puncture immune cells and clear the way for infection. But only recently have they begun to understand exactly how these toxins work.

Earlier this year, researchers explained how one of those toxins, a protein called LukED, fatally lyses T-cells, macrophages and dendritic cells, all types of white blood cells that help fight off infection. The LukED toxin, they showed, binds to a surface receptor called CCR5 (the same one exploited by HIV).  But their discovery failed to explain how the bacterial toxin kills other types of white blood cells, such as neutrophils, that lack the CCR5 receptor.

Now some recent work solves this puzzle, showing for the first time how receptors on neutrophils (a common type of white blood cell) also enable binding of the LukED toxin. The researchers found that LukED latches onto surface receptors called CXCR1 and CXCR2, creating the same deadly pores that it does when it latches onto CCR5 receptors.

For further details, refer to the following paper:

EMA and FDA Release QbD Guidance


FDA and the European Medicines Agency (EMA) have published a second joint question-and-answer document that provides guidance on the quality-by-design (QbD) concept. The guidance focuses on design space verification and reflects the conclusions reached by European Union and US regulators.

In March 2011, FDA and EMA launched a three-year pilot program for the parallel assessment of certain quality or chemistry manufacturing and control (CMC) sections of applications that are relevant to QbD. The objective of the program is to share knowledge and harmonize implementation of the QbD concept. Experts from the Japanese Pharmaceuticals and Medical Devices Agency participate as observers in the program.

According to EMA, the pilot program is open to selected procedures, including applications for initial marketing authorizations, type-II variations, and scientific advice. Participation in the pilot program is voluntary. Interested applicants and sponsors should notify both agencies three months prior to submission of an application.

To access the document, see FDA/EMA.

Evolving E. coli


Scientists show that Escherichia coli cells continue to become more fit, even over tens of thousands of generations.

Since 1988, Michigan State University’s Richard Lenski has led the Escherichia coli Long-term Experimental Evolution Project (LTEE)—12 flasks of bacteria that have been evolving in the lab for more than 58,000 generations. In the latest report from the project, Lenski and colleagues have shown that peak fitness—the point in an organism’s evolution when it is maximally adapted to its environment—does not seem to have an upper limit.

Lenski’s team thawed E. coli taken from the LTEE at 41 different time points during the past 25 years and cultured the samples from different generations together in varied combinations with the most current generations. They evaluated fitness based on how fast the bacteria grew and found that even between 40,000 and 50,000 generations, there was a 3 percent increase in mean fitness. The scientists generated a model, which predicted that even if the experiment continued for 2.5 billion years, there would not be an upper bound to fitness.

Their findings have been published in the journal Science. The paper is titled "Long-Term Dynamics of Adaptation in Asexual Populations".

Get Smart About Antibiotics Week 2013

Infections caused by resistant bacteria have become more common, and many bacteria have become resistant to multiple antibiotics. CDC released a report in September 2013 documenting that each year more than two million people in the United States get infections that are resistant to antibiotics and at least 23,000 people die as a result. This trend demands urgent action by patients, healthcare providers, facility administrators and health care insurers to preserve the last lines of defense against many of these germs. In conjunction with Get Smart About Antibiotics Week (November 18-24), the American Academy of Pediatrics, in collaboration with CDC, released new guidance for treating common pediatric upper respiratory infections.

The abstract from the journal reads:

“Most upper respiratory tract infections are caused by viruses and require no antibiotics. This clinical report focuses on antibiotic prescribing strategies for bacterial upper respiratory tract infections, including acute otitis media, acute bacterial sinusitis, and streptococcal pharyngitis. The principles for judicious antibiotic prescribing that are outlined focus on applying stringent diagnostic criteria, weighing the benefits and harms of antibiotic therapy, and understanding situations when antibiotics may not be indicated. The principles can be used to amplify messages from recent clinical guidelines for local guideline development and for patient communication; they are broadly applicable to antibiotic prescribing in general. Pediatrics 2013;132:1146–1154”

Listeria and disinfectant resistance

Research suggests that listeria is developing resistance to the most frequently used compounds. As part of studies into mechanisms of resistance, Stephan Schmitz-Esser at the University of Veterinary Medicine, Vienna (Vetmeduni Vienna) has uncovered the mechanism for resistance to benzalkonium chloride.

The research centres on listeria acquiring new genetic material from other bacteria.

For more on this research, refer to:

15 Years in Pharmaceutical Microbiology


How has the pharmaceutical microbiology arena progressed over the last 15 years? In a review of some major hurdles and milestones, the American Pharmaceutical Review has interviewed some leading microbiologists including Donald Singer (Global Lead Quality Manager, Microbiology, GlaxoSmithKline) and Luis Jimenez, Ph.D. (Biology and Horticulture Department, Bergen Community College).

For example, Donald Singer notes:

"In Microbiology, some milestones I can note:
  • Regulatory scrutiny of sterile products manufacturing has continued to increase and has led to guidance requirements for risk rationale; for example, the rewrite of 21CFR612 for sterility testing, the FDA Guideline for Container Closure Integrity in lieu of Sterility Testing, the MHRA ‘GMP’ Annex 1 pre-fi ltration bioburden action ‘limit’, and the USP <1116> contamination recovery rate recommendation
  • Alignment of regulatory guidance with ICH Quality standards Q7, Q8 and Q9 which impact microbiological risk
  • Increased published articles and books about pharmaceutical microbiological control
  • Forums and media for communicating microbiological issues and solutions have increased Some hurdles I have seen are:
  • Diffi culty in the implementation of new alternative methodologies and concern regarding ‘equivalency’ to pharmaceutical standard methods
  • Economics leading to Microbiology labs to lean staffi ng, less capabilities, less time to innovate, and concern for improvement of supervision of analytical teams that lack experience or suffi cient knowledge in the fi eld
  • Increase in instrument-based technology jumped ahead of adequate education for users to make good scientifi c decisions
  • Continuation in pockets of the industry where management lacking scientific knowledge oversee microbiology operations."

New insight into irritable bowel syndrome and gut bacteria

New findings from the Institute of Food Research are providing insights into the interaction between bacteria and mucins, and how the specificity of these interactions affects health. The IFR researchers looked at Ruminococcus gnavus. This is a common species of gut bacteria found in over 90% of people, including infants just a few days old. It has also been implicated in gut-related health conditions. A number of studies have shown that patients suffering from Inflammatory Bowel Diseases have a disproportionate representation of R. gnavus.

This study looked at two different R. gnavus strains. Although both R. gnavus strains can use mucins, only one had the ability to survive when mucins were the sole source of food.

Comparing the genomes of the R. gnavus strains identified gene clusters used to breakdown mucins. Differences in these genes explain the different abilities of the strains to use mucins. The mucin sugar structures change in different parts of the gut and over time, suggesting the strains may be adapted for different environments or to colonise us at different times. For example, the R. gnavus strain adapted to survive solely on mucins may give it the ability to colonise the guts of newborn babies, when mucins represent the only sources of sugars for bacteria. In adults, the strains of bacteria that degrade mucins are the ones most likely to contact the cells underneath the mucus and so these strains are the ones most likely to influence health.

For further details, see the following paper:

Bats and disease

Emerging infectious diseases pose a significant threat to human and animal welfare. A high proportion of emerging and reemerging infectious diseases are zoonoses derived from wildlife. Bats harbour more zoonotic viruses per species than rodents and are now recognised as a significant source of zoonotic agents. Henipaviruses, coronaviruses, filoviruses, and the rabies-causing lyssaviruses have all been shown to be transmissible from bats to humans - often through an intermediate host—with fatal consequences. Despite the obvious risk bat viruses pose to human health, it must be acknowledged that most outbreaks of bat-borne zoonotic diseases are a consequence of human activities. From an ecological perspective, bats are a remarkable and ecologically important group with many unique biological features.

Virus testing of raw materials


The European Medicines Agency have issued some reports examining the necessity of screening certain in-coming raw materials for viruses.

These are:

Use of bovine serum in the manufacture of human biological medicinal products. Reference: CPMP/BWP/1793/02. Issued in June 2013.

With this document, the guidance notes: “Different risks are associated with the use of such raw materials. Indeed, the nature and quality of the bovine serum used in the manufacturing process can profoundly influence the quality of the finished product. In particular, the potential presence of extraneous agents in bovine serum represents a risk to the safety of the biological medicinal product.”

Use of porcine trypsin used in the manufacture of human biological medicinal products. Reference: EMA/CHMP/BWP/814397/2011. Issued in March 2013.

From antimicrobial to anticancer peptides

Antimicrobial peptides (AMPs) are part of the innate immune defense mechanism of many organisms. Although AMPs have been essentially studied and developed as potential alternatives for fighting infectious diseases, their use as anticancer peptides (ACPs) in cancer therapy either alone or in combination with other conventional drugs has been regarded as a therapeutic strategy to explore.

This is the basis of an interesting article by Diana Gaspar, and colleagues at the Instituto de Medicina Molecular, Faculdade de Medicina da Universidade de Lisboa, Lisbon, Portugal. The article has been published by Frontiers in Microbiology.

The reference is:

Where did syphilis come from?


Did Columbus bring the disease syphilis back with him from the New World, or was it in Europe all along? Katherine Wright, winner of the Wellcome Trust science writing prize 2013, has investigated this issue in a fascinating article.

Here is an excerpt, all about the spread of Treponema pallidum:

"As its many names attest, contemporaries of the first spread of syphilis did not know where this disease had come from. Was it indeed the fault of the French? Was it God's punishment on earthly sinners?
Another school of thought, less xenophobic and less religious, soon gained traction. Columbus's historic voyage to the New World was in 1492. The Italian soldiers were noticing angry chancres on their genitals by 1494. What if Columbus had brought the disease back to Europe with him as an unwelcome stowaway aboard the Pinta or the Niña?"

New book: Sterility, Sterilisation and Sterility Assurance



A new book of interest has been published. The book is titled ‘Sterility, sterilisation and sterility assurance for pharmaceuticals: Technology, validation and current regulations’ and it has been written by Tim Sandle. The book has been published by Woodhead Biomedicine, an imprint of Elsevier.

The book addresses the following concerns:
  • The main sterilisation methods of physical removal, physical alteration and inactivation.
  •  Discussions relating to medical devices, aseptically filled products and terminally sterilised products.
  • Bacterial, pyrogenic, and endotoxin risks to devices and products.
  • The latest technology in the field.
  • Current thinking behind risk assessment and good manufacturing practices. 
Throughout 18 chapters, the book outlines and discusses sterilization technology and the biopharmaceutical manufacturing process, including aseptic filling, as well as aspects of the design of containers and packaging and addresses the cleanroom environments in which products are prepared.

Failure to adequately control any microbial challenge associated within process or product by robust sterilisation will result in a contaminated marketed product, with potential harm to the patient. Sterilisation is therefore of great importance to healthcare and the manufacturers of medical devices and pharmaceuticals. Sterility, sterilisation and sterility assurance for pharmaceuticals examines different means of rendering a product sterile by providing an overview of sterilisation methods including heat, radiation and filtration. The book outlines and discusses sterilisation technology and the biopharmaceutical manufacturing process, including aseptic filling, as well as aspects of the design of containers and packaging, as well as addressing the cleanroom environments in which products are prepared. Consisting of 18 chapters, the book comprehensively covers sterility, sterilisation and microorganisms; pyrogenicity and bacterial endotoxins; regulatory requirements and good manufacturing practices; and gamma radiation. Later chapters discuss e-beam; dry heat sterilisation; steam sterilisation; sterilisation by gas; vapour sterilisation; and sterile filtration, before final chapters analyse depyrogenation; cleanrooms; aseptic processing; media simulation; biological indicators; sterility testing; auditing; and new sterilisation techniques.

The book is available directly from the publisher or via Amazon and other good booksellers (such as Waterstones and Powells).

Microbes can help solve murder mysteries

Studies on decomposing mice suggest that the microbial content of a corpse can offer clues as to how old a body is and the approximate time that death occurred.
From studies on dead and decaying mice, where the microorganisms were examined, researchers have been able to narrow down the times of death of mice to three-day windows. This is by identifying the microbes present in and on their bodies using DNA sequencing. This came from studies on 40 decomposing mice over 48 days.
Commenting on the study, Jessica Metcalf, a postdoc at the University of Colorado Boulder and an author of the study, told NPR’s All Things Considered that: "What we’re looking for is whether the microbial community changes in a clock-like manner." The answer was 'yes it does'.

To show this, researchers collected samples of archaea, microbial eukaryotes, and bacteria from their skin, from within their abdominal cavities, and from soils associated with each corpse. They found that the bacteria, particularly those from the order Rhizobiales, were especially useful for estimating time of death.
The team is now working to estimate time of death in humans using a similar approach. Currently researchers estimate time of death by looking at the development of blow fly larvae in corpses. The new research suggests that the microorganisms could present an equivalent method or even something more accurate.
The findings have been published in the journal eLife. The free-to-read paper is titled "A microbial clock provides an accurate estimate of the postmortem interval in a mouse model system."

Screening for hospital pathogens

A new microfluidic device (for handling small volumes of fluids) has been developed by researchers to screen for hospital pathogens like Pseudomonas aeruginosa.
Pseudomonas aeruginosa is a bacterium common in soil and water; it has also been associated with hospital acquired infections. People with weakened immune systems are at a particular risk, especially from the disease cystic fibrosis (the forming thick layers of mucus in the lungs).
To help the diagnosis of the pathogen, MIT researchers have developed a new microfluidic device that could speed the monitoring of bacterial infections associated with cystic fibrosis and other diseases. The advantage with the device is that it can screen patient samples faster and with greater accuracy.
The microfluidic chip is etched with tiny channels, each resembling an elongated hourglass with a pinched midsection. Researchers injected bacteria through one end of each channel, and observed how bacterial cells travel from one end to the other. The cells were propelled by electrical forces. Depending on the type of bacterial cell, they either passed through the channel's narrow section or were trapped at the opening. By using this method, the researchers could screen which bacteria are pathogens and which are harmless.
To demonstrate the method, the researchers examined ordinary strains of P. aeruginosa, along with mutant strains that were missing certain genes required to make the dangerous pathogens. From their experiments, the researchers found that their device is able to distinguish benign bacterial cells from those that are more likely to be pathogenic.
The study was a collaboration between scientists at Ghent University, Belgium, and the University of Queensland, in Australia. The findings have been published in the journal PLOS One. The paper is called “Dielectrophoresis-Based Discrimination of Bacteria at the Strain Level Based on Their Surface Properties.”

CRE: The new superbug?



Carbapenem-resistant Enterobacteriaceae (CRE) is a group of gram-negative bacteria, including Klebsiella species and Escherichia coli, that have high levels of resistance to carbapenem antibiotics.

On 7 March 2013, CNN reported:

“Hospitals need to take action against the spread of a deadly, antibiotic-resistant strain of bacteria, says the Centers for Disease Control and Prevention. The bacteria kill up to half of patients who are infected.

“The bacteria, called carbapenem-resistant Enterobacteriaceae or CRE, have increased over the past decade and grown resistant to even the most powerful antibiotics, according to the CDC. In the first half of 2012, 200 health care facilities treated patients infected with CRE.”

According to the CDC:

“Healthy people usually do not get CRE infections. In healthcare settings, CRE infections most commonly occur among patients who are receiving treatment for other conditions. Patients whose care requires devices like ventilators (breathing machines), urinary (bladder) catheters, or intravenous (vein) catheters, and patients who are taking long courses of certain antibiotics are most at risk for CRE infections.

“Some CRE bacteria have become resistant to most available antibiotics. Infections with these germs are very difficult to treat, and can be deadly—one report cites they can contribute to death in up to 50% of patients who become infected.”

Elsevier has some interesting references to CRE, which can be found here.

Consideration for infection control

Infection control is one of the most important aspects of healthcare and is based on the objectives of preventing transmission of infection between patients, and on the prevention of patients from contracting nosocomial infections (hospital acquired infections).

To explore the main routes of contamination and to explore some of the preventative measures that can be adopted, Tim Sandle and Jennifer Sandle have written a review article for Arab Medical Hygiene.


The article considers surfaces, equipment, clothing, flooring, staff screening, staff training, vaccination, good building design, infection surveillance, hand sanitisation, and cleaning and disinfection.

Key concerns for infection control


Clostridium difficile and norovirus appear to be the main causes of concern for infection control professionals as we enter the winter months according to the latest survey. Conducted at Infection Prevention 2013, the survey revealed that 48% of the respondents highlighted C difficile as the primary cause of concern and 36% highlighted norovirus.

Carried out by Bioquell, a provider of no-touch infection control solutions to the healthcare industry, the survey of 170 infection control nurses and senior practitioners were asked to rank various pathogens in order of priority and also indicate any others that they were concerned about. The findings revealed that CPE (carbapenemase-producing Enterobacteriaceae) was becoming a major concern (19%). Additionally, Acinetobacter (2%), MRSA (4%) and VRE (4%) were further potential issues being faced by infection control teams.

New Microbe Found in Spacecraft Cleanrooms

A rare, recently discovered microbe that survives on very little to eat has been found in two places on Earth: spacecraft cleanrooms in Florida and South America.

Tersicoccus phoenicis is an aerobic, non-motile, Gram-reaction-positive cocci and is associated with two strains: 1P05MAT and KO_PS43. The bacteria is berry-shaped and found in spacecraft assembly clean room facilities: Tersi is from the Latin for clean, Coccus is from the Greek for berry and Phoenicis is derived from NASA's Phoenix Mars Lander, the spacecraft being prepared in 2007 when the bacterium was first discovered in the Florida clean room.

Microbiologists often do thorough surveys of bacteria and other microbes in spacecraft cleanrooms. Fewer microbes live there than in almost any other environment on Earth, but the surveys are important for knowing what might hitch a ride into space. If extraterrestrial life is ever found, it would be readily checked against the census of a few hundred types of microbes detected in spacecraft cleanrooms.

The work to keep cleanrooms extremely clean knocks total microbe numbers way down. It also can select for microbes that withstand stresses such as drying, chemical cleaning, ultraviolet treatments, and lack of nutrients. Perversely, microbes that withstand these stressors often also show elevated resistance to spacecraft sterilization methodologies such as heating and peroxide treatment.

"We want to have a better understanding of these bugs, because the capabilities that adapt them for surviving in cleanrooms might also let them survive on a spacecraft," says microbiologist Parag Vaishampayan of NASA's Jet Propulsion Laboratory, Pasadena, Calif., lead author of the 2013 paper about the microbe. "This particular bug survives with almost no nutrients."

This population of berry-shaped bacteria is so different from any other known bacteria, it has been classified as not only a new species, but also a new genus, the next level of classifying the diversity of life. Its discoverers named it Tersicoccus phoenicis. Tersi is from Latin for clean, like the room. Coccus, from Greek for berry, describes the bacterium's shape. The phoenicis part is for NASA's Phoenix Mars Lander, the spacecraft being prepared for launch in 2007 when the bacterium was first collected by test-swabbing the floor in the Florida cleanroom.

Some other microbes have been discovered in a spacecraft cleanroom and found nowhere else, but none previously had been found in two different cleanrooms and nowhere else. Home grounds of the new one are about 2,500 miles apart, in a NASA facility at Kennedy Space Center and a European Space Agency facility in Kourou, French Guiana.

A bacterial DNA database shared by microbiologists worldwide led Vaishampayan to find the match. The South American detection had been listed on the database by a former JPL colleague, Christine Moissl-Eichinger, now with the University of Regensburg in Germany. She is first co-author of the paper published this year in the International Journal of Systematic and Evolutionary Microbiology identifying the new genus.

The same global database showed no other location where this strain of bacteria has been detected. That did not surprise Vaishampayan. He says, "We find a lot of bugs in cleanrooms because we are looking so hard to find them there. The same bug might be in the soil outside the cleanroom but we wouldn't necessarily identify it there because it would be hidden by the overwhelming numbers of other bugs."

A teaspoon of typical soil would have thousands more types of microbes and billions more total microbes than an entire cleanroom. More than 99% of bacterial strains, as identified from DNA sequences, have never been cultivated in laboratories, a necessary step for the various types of characterization required to identify a strain as a new species.

Microbes that are tolerant of harsh conditions become more evident in cleanroom environments that remove the rest of the crowd.

"Tersicoccus phoenicis might be found in some natural environment with extremely low nutrient levels, such as a cave or desert," Vaishampayan speculates. This is the case for another species of bacterium (Paenibacillus phoenicis) identified by JPL researchers and currently found in only two places on Earth: a spacecraft cleanroom in Florida and a bore hole more than 1.3 miles deep at a Colorado molybdenum mine.
Ongoing research with Tersicoccus phoenicis is aimed at understanding possible ways to control it in spacecraft cleanrooms and fully sequencing its DNA. Students from California State University, Los Angeles, have participated in the research to characterize the newly discovered species.
