Vincent and Dickson continue their discussion of the obligate intracellular protozoan Toxoplasma gondii with a consideration of the clinical consequences of infection and pathogenesis.
Global fish farming may be the solution to the impending collapse of the commercial fishing industry, but penned fish are susceptible to infectious diseases. Infection with salmon infectious anemia virus, an orthomyxovirus, lead Wal-Mart to stop buying farmed salmon from Chile, the world’s secon... Read More
Waterborne illnesses are far from eradicated, and they're more than just a case of diarrhea. Americans shell out an estimated $500 million in health care costs to treat the conditions each year, according to a new report from the Centers for Disease Control and Prevention.
In a study presente... Read More
In the latest exploration into the universe of organisms inhabiting our bodies, microbiologists have discovered new viral genes in faeces. They find that the composition of virus populations inhabiting the tail ends of healthy intestines (as represented in our stools) is unique to each individua... Read More
Seen here via immunohistochemical staining of a gastric biopsy is the Heliobacter Pylori bacteria, or H. Pylori if you're in a hurry.
Able to survive the intensely acidic environment that is the human stomach, H. Pylori actually gets downright comfortable there. The bacterium has flagella and... Read More
If I take a piece of pizza that's been sitting on the table awhile and microwave it for one minute, would that kill bacteria and decrease the chance of food poisoning? -- David Chattin-McNichols

Sewage that overflows into urban creeks and streams during periods of heavy rain can promote the spread of West Nile virus, a study led by Emory University finds.
The analysis of six years of data showed that people living near creeks with sewage overflows in lower-income neighborhoods of Sou... Read More
Some bacteria have adapted to super cold environments for millions of years. And scientists have isolated some of the essential genes that allow bacteria to tolerate their harsh living conditions—because these same genes might help in the creation of new vaccines. The investigators published the... Read More
Five percent of the population of Key West, Florida -- more than 1,000 people -- have been infected at some point with the dengue virus, government researchers reported on Tuesday.

Deadly yet easily preventable bloodstream infections continue to plague American hospitals because facility administrators fail to commit resources and attention to the problem, according to a survey of medical professionals released Monday.
An estimated 80,000 patients per year develop cathe... Read More
Creating vaccines against some of the most dangerous bacterial pathogens might be as simple as giving them a cold — or at least a cold gene.
By replacing a single gene in pathogenic bacteria with a gene from bacteria that live in the arctic, scientists report that they have developed a modifi... Read More
Ear infections: almost every kid has suffered through them at least once, making otitis media the most common reason for pediatric visits and new antibiotic prescriptions in children. But those little bottles of sweet pink antibiotics don’t always clear up ear infections. Bacteria often form m... Read More
Most people fail to properly prevent the spread of contagious and infectious germs when coughing and sneezing, according to a study by medical students in New Zealand.
For the study, the students secretly watched hundreds of people cough or sneeze at a train station, a shopping mall and a hos... Read More
HIV research is undergoing a renaissance that could lead to new ways to develop vaccines against the AIDS virus and other viral diseases.
In the latest development, U.S. government scientists say they have discovered three powerful antibodies, the strongest of which neutralizes 91% of HIV str... Read More
Dr. Alexander Khoruts had run out of options.
In 2008, Dr. Khoruts, a gastroenterologist at the University of Minnesota, took on a patient suffering from a vicious gut infection of Clostridium difficile. She was crippled by constant diarrhea, which had left her in a wheelchair wearing diaper... Read More
Animal lovers may be accidentally killing one of the UK's best-loved mammals with their kindness, scientists believe. Red squirrels may be picking up potentially deadly bacteria from the hands and skin of people putting out food for them.
The wildlife specialists are far from proving a defin... Read More
Nearly 1 out of every 25 restaurant-associated foodborne outbreaks with identified food sources between 1998 and 2008 can be traced back to contaminated salsa or guacamole, more than double the rate during the previous decade, according to research released by the Centers for Disease Control and...
