A streak plate of Strep pyogenes on blood agar, stock culture used for class, was kept at room temp for 1 month. Before disposal a contaminant, presumably environmental, was seen on the plate. The pigment was opaque tan/yellow and with a mucoid surface. Lobate marigins with raised irregular-rh... Read More
Foot-and-mouth disease virus (FMDV) infects cloven-hoofed animals such as cattle, pigs, sheep, goats, and many wild species. The disease caused by this virus is a substantial problem for farmers because infected animals cannot be sold. Transgenic pigs have now been produced which express a short... Read More
Washington, DC – September 4, 2015 - Decontamination protocols eradicated both methicillin-resistant Staphylococcus aureus (MRSA) and antibiotic resistant, pathogenic intestinal bacteria, the Enterobacteriaceae, from a pig farm. The research appears online September 4th in ASM’s journal Applied ... Read More
An international team of researchers has developed the largest genomic data set in the world on Lassa virus (LASV). The new genomic catalog contains nearly 200 viral genomes collected from patient samples in Sierra Leone and Nigeria, as well as field samples from the major animal reservoir, or h... Read More
MIT-WHOI Graduate student Kristen Hunter-Cevera describes the challenges and obstacles involved with growing marine microbes (in her case, Synechococcus) in a laboratory setting, and outlines the value of her research in understanding marine biogeochemistry. Read More

A scientific peek into bacteria boudoirs is revealing how "sex" among disease-causing microbes can lead different species or strains to become resistant to antibiotic medications. Read More
Barbara Hinney and her colleagues from the Institute for Parasitology at the University of Veterinary Medicine, Vienna, screened 298 faecal samples taken from cats across Austria for single-cell intestinal parasites, so called enteric protozoa. The samples came from private households, catteries... Read More
Disease-causing viruses engage their hosts in ongoing arms races: positive selection for antiviral genes increases host fitness and survival, and viruses in turn select for mutations that counteract the antiviral host factors. Studying such adaptive mutations can provide insights into the distan... Read More
Research presented at the 2015 AACC Annual Meeting & Clinical Lab Expo will expand on the studies that led to a fingerprick Ebola test becoming the first and only rapid diagnostic for this disease to receive approval from the World Health Organization (WHO). This test could prove vital to breaki... Read More
A permissive vaccine prevents disease in the immunized host, but does not block virus infection. Would a permissive vaccine lead to the emergence of more virulent viruses?
This hypothesis is based on the notion that viruses which kill their hosts too quickly are not efficiently transmitted, a... Read More
The CRISPR-Cas9 system has been in the limelight mainly as a revolutionary genome engineering tool used to modify specific gene sequences within the vast sea of an organism's DNA. Cas9, a naturally occurring protein in the immune system of certain bacteria, acts like a pair of molecular scissors... Read More
Pictured is a culture of Mycobacterium tuberculosis growing colonies in the distinctive "serpentine cord" form seen in many strains of M. tuberculosis. These cords are made up of chains of cells that make chains due to a cell wall factor of MTB.
The cell wall structure of Mycobacterium is a m... Read More
Invasive Salmonella infections in sub-Saharan Africa are a major cause of child illness and deaths, a new body of research into this usually overlooked infectious disease has revealed. Read More
Johns Hopkins Bloomberg School of Public Health researchers say they have discovered a new way that the most prevalent disease-causing fungus can thwart immune system attacks. Read More
CORVALLIS, Ore. - About 20 million years ago a single flea became entombed in amber with tiny bacteria attached to it, providing what researchers believe may be the oldest evidence on Earth of a dreaded and historic killer - an ancient strain of the bubonic plague. Read More
Melanin produced by a marine bacteria Bacillus spp. has shown shown to have good anti-inflammatory activity. The pigment had shown to inhibit inflammatory enzymes cycloxygenase, lipooxygenase, myeloperoxide,NO synthase in vitro at a concentration which was non-cytotoxic..This will be a breakthro...

TORONTO, Aug. 17, 2015--Promoting breastfeeding could lead to a substantial reduction in common infections and even deaths that are more common in Indigenous infants than non-Indigenous infants, a new study suggests. Read More
When the influenza vaccine is well matched to the prevailing strains of flu in a given season, patients in nursing homes are significantly less likely to be hospitalized or to die of pneumonia and other influenza related causes. The finding comes from a study of more than 1 million Medicare fee-... Read More
