Genomic study of 412 anthrax strains provides new virulence clues

By analyzing genomic sequences from more than 400 strains of the bacterium that causes anthrax, researchers have provided the first evidence that the severity – technically known as virulence – of specific strains may ...

Researchers develop model of toxoplasmosis evolution

Toxoplasmosis is an infectious disease caused by the spread of Toxoplasma gondii, a parasitic alveolite with an interesting life cycle. It exists in three forms. First, oocysts are produced in cats and passed in feces or ...

Recent research uncovers surprises about antibiotic resistance

It's thought that antibiotic resistance is associated with a fitness cost, meaning that bacteria that develop antibiotic resistance must sacrifice something in order to do so. Because of this, proper use of antibiotics should ...

Two-for-one bacterial virulence factor revealed

We've all seen the headlines. "Man found to be shedding virulent strain of polio"; "Virulent flu strain in Europe hits the economy"; "Most virulent strain of E. coli ever seen contains DNA sequences from plague bacteria."
