I offer this as an echo to Elio's post from last October, Teaching E. coli to Endocytose. There Elio reported the recent education of E. coli by the heterologous expression of a mammalian gene. I tell of a bacterium instructed by a phage.
Apparently Pseudomonas phage φ6 missed that classic 19... Read More
How many different viruses are there on planet Earth? Twenty years ago Stephen Morse suggested that there were about one million viruses of vertebrates (he arrived at this calculation by assuming ~20 different viruses in each of the 50,000 vertebrates on the planet). The results of a new study s... Read More

Researchers have found that apoptosis, a natural process of programmed cell death, can reactivate latent herpesviruses in the dying cell. The results of their research, which could have broad clinical significance since many cancer chemotherapies cause apoptosis, was published ahead of print in ... Read More
There have been several outbreaks of highly pathogenic H5N1 avian influenza viruses affecting humans over the past decade, the causes of which have been limited to direct human contact with infected birds. Recent publications suggest that a very small number of coding mutations in the viral HA g... Read More
Porcine reproductive and respiratory syndrome (PRRS) virus remains a very important disease of swine in the United States. At the University of Minnesota Veterinary Diagnostic Laboratory, hundreds of samples are routinely tested for this virus by polymerase chain reaction (PCR) every month. This... Read More
Tuberculosis (TB) drug resistance is not an all-or-none phenomenon, according to new research from Rutgers, The State University of New Jersey. Rather, TB-causing bacteria often accumulate mutations in a step-wise fashion, with the initial mutation having minimal impact but poising the bug to la... Read More

Bacteria in people's digestive systems -- gut germs -- seem to affect whether they become overweight or obese, and new research sheds more light on why that might be.
The findings, from an international team of scientists, also suggest that a diet heavy in fiber could change the makeup of the... Read More

What will the next big zoonotic virus be? Most emerging infectious diseases are zoonoses, and many, if not most, of them are caused by viruses, but right now we have little idea what viruses are out there in livestock and wildlife, let alone which one might be next in line to cause a human pande...

Flu vaccination is no longer merely a choice between a jab in the arm or a squirt in the nose. This fall, some brands promise a little extra protection.
For the first time, certain vaccines will guard against four strains of flu rather than the usual three. Called quadrivalent vaccines, these... Read More
Scientists have found another chink in bacteria's armour, mapping for the first time the structure of a protein that plays an important role helping infection gain a foothold in the body.
