Minor variants of flu strains, which are not typically targeted in vaccines, carry a bigger viral punch than previously realized, according to a new study that examined samples from the 2009 pandemic in Hong Kong. Read More
PHILADELPHIA - For years, researchers have noted a tantalizing link between some neurologic conditions and certain species of the herpes virus. In patients with Alzheimer's disease, multiple sclerosis, and cerebellar ataxia, among other neuropathies, the cerebrospinal fluid teems with Epstein-Ba... Read More
Salmonella is a zoonotic foodborne pathogen and a public health concern. It has been estimated that this pathogen causes ~1.2 million illnesses, ~20,000 hospitalizations, and ~400 deaths in the US annually (Scallan et al., 2011). Salmonella has ~2,600 serotypes (serovars) and numerous hosts and ... Read More
Researchers at University of California, San Diego School of Medicine have discovered that HIV infection of human immune cells triggers a massive increase in methylation, a chemical modification, to both human and viral RNA, aiding replication of the virus. The study, published February 22, 2016... Read More
This picture was taken in early October 2014 in the Washington, DC metro area. The temperature that week had been in the mid-70's during the day to the low 60's at night (Fahrenheit), and it hadn't been too humid. This had grown at the base of a tree, and was very large -- my hand is in there fo... Read More
Australian scientists have for the first time revealed how malaria parasites cause an inflammatory reaction that sabotages our body's ability to protect itself against the disease. Read More
Having confirmed the first cases of infection in Suriname then in French Guiana, the Institut Pasteur in French Guiana has sequenced the complete genome of the Zika virus, which is responsible for an unprecedented epidemic currently sweeping through the tropical regions of the Americas. Publishe... Read More

New research demonstrates how climate change and the immune reaction of the infected individual can affect the long-term and seasonal dynamics of parasite infections. The study, led by Penn State University scientists, assessed the infection dynamics of two species of soil-transmitted parasites ... Read More
Viruses have proven to be wily foes. Attempts to fend off viruses that cause the common cold or flu have failed, and new viral outbreaks such as dengue, Ebola, or Zika continue to elude drugs.
Given these challenges, scientists are tackling the problem from a different angle. The want to boos... Read More
New research shows how certain microbes exploit proteins in nearby bacteria to deliver toxins and kill them. The mechanisms behind this bacterial warfare, the researchers suggest, could be harnessed to target pathogenic bacteria. Read More

Unknown Fungal Contaminant found on TSA plate that had been refrigerated for 1 month. Colony was raised in the center with deep groves around the colony. Green spore formation was seen in the middle with white non-spore forming hyphae towards the edges. Read More
Unknown organism, possible Bacillus spp, washed hand print done on a TSA plate. Organism was the size of a dime, muciod/ rhizoid in the center and mat/smooth at the outer edges. Read More
The picture was taken after my students at the Inter American University of Puerto Rico-San German, learned the technique of water filtration analysis of fecal coliforms in water. They filtrated a mL of groundwater from a nearby aquifer and transferred the filter to Endo agar plates. The pictur... Read More
