As more and more information becomes available, one marvels (and also frets) at the sophisticated strategies that pathogens have evolved in order to evade their hosts’ defense mechanisms. Many pathogens of plants and animals deliver effectors into their hosts in order to suppress immune response... Read More
An FDA advisory committee has voted 14-1 in favor of expanding the indication for the pneumococcal 13-valent conjugate vaccine (Prevnar 13) to include use in adults 50 and older.
Currently the Pfizer vaccine is approved only for use in children.
The FDA's Vaccines and Related Biologics Adv... Read More
Cancer has left its 'footprint' on our evolution, according to a study which examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species.
Viral relics are evidence of the ancient battles our genes have fought against infection. Occasionally the retroviruses th... Read More
The American Society for Microbiology hosted a live podcast of This Week in Virology with Vincent Racaniello with co-host Alan Dove that includes guests Paul Duprex, Director of Cell and Tissue Imaging Core, Boston University, National Emerging Infectious Diseases Laboratories (NEIDL), and Ju...

The bacteria Enterococcus can cause infections that typically target the digestive tract or bowel; if the bacteria spread, an abdominal abscess or urinary infection could result. Enterococcus also can invade the bloodstream, leading to meningitis, pneumonia or endocarditis — an infection of the ... Read More
Viruses are not usually regarded as living cells. A virus 'particle' requires a living host cell in order to reproduce. Although we usually think of viruses as causing diseases, they also are an integral part of natural ecosystems controlling the size of bacterial populations by preying on them.... Read More

Microbiota buffs repeat it often these days, proudly reminding the public that the microbial cells associated with humans outnumber their host cells by a ratio of ten-to-one. In his letter in the February 2014 Microbe, however, Judah L. Rosner of the National Institutes of Health (NIH) makes a s... Read More
For many people microbes are associated with infections, diseases and in general mainly negative things but some microbes actually do more good than bad for us. We often take for granted that without microbes we would not have many things that we eat and use everyday and, as a matter of fact, hu... Read More
NEARLY half of consumers ignore use-by dates on food with experts warning they are putting their health at risk, a report has revealed.
Dr Wayne Anderson, food science and standards director, said food may be badly contaminated even if it appeared good enough to eat.
"We would caution peop... Read More
Lessons learned from Florence Nightingale could prevent the spread of harmful bugs by allowing "friendly" bacteria into hospitals, an expert has claimed.
Sterile conditions in wards and operating theatres may be doing more harm than good by wiping out organisms that keep dangerous microbes at b... Read More
Saudi scientists have found gene fragments of the deadly Middle East Respiratory Syndrome (MERS) virus in air from a barn housing an infected camel and say this suggests the disease may be transmitted through the air.

The FDA has approved a new compound for the treatment of acute lymphoblastic leukemia (ALL) patients who are allergic to asparaginase derived from Escherichia coli.
The agency gave the okay to asparaginase Erwinia chrysanthemi (Erwinaze) as a replacement for E. coli-derived asparaginase or pe... Read More
We’re in a sad and weird place in biomedical science. In the 1940’s we got penicillin, in the following 30 years another 13 different classes of antibiotic were introduced. Since 1970 the number of new classes has dropped to a worrying 2. Since then we have found new ways to arrange the deckcha... Read More
Beautiful metallic colonies of E. coli growing on Endo agar which is being used mostly for differentiation and isolation of Enterobacteriaceae strains.
The Human Microbiome Project revealed tens of trillions of microbes residing in and on humans. Now scientists are taking a census of plant microbes—and not just the hundreds of billions found in soils. Distinct microbial communities live inside roots, on leaves and within flowers, and all in all... Read More
