Almost every second woman suffers from a bladder infection at some point in her life. Also men are affected by cystitis, though less frequently. In eighty percent of the cases, it is caused by the intestinal bacterium E. coli. It travels along the urethra to the bladder where it triggers painful... Read More
A type of bacteria plucked from the bottom of the ocean could be put to work neutralizing large amounts of industrial carbon dioxide in the Earth's atmosphere, a group of University of Florida researchers has found. Read More
Our sensitivity instruments rarely ever go down, but when they do our lab uses Kirby-Bauer testing to perform antimicrobial susceptibility testing in our laboratory. This testing involves placing antibiotic-infused discs on a standardized inoculum of bacteria spread in a lawn onto a Mueller Hint... Read More
Students in the summer STEM program at Cabrillo (these were college age students) were asked to do a handprint of their unwashed hand then of their hand after washing. This is a before and after of what the majority of the plates looked like. Plates were incubated for 48 hrs at 37 degrees C ... Read More

PROVIDENCE, R.I. [Brown University] -- A new study of the relationship between violent conflict and HIV incidence in sub-Saharan Africa finds that HIV incidence may be at its worst in the period before hostilities break out. The Brown University analysis reports that the rate of new infections r... Read More
The Zika virus infects a type of neural stem cell that gives rise to the brain's cerebral cortex, Johns Hopkins and Florida State researchers report March 4 in Cell Stem Cell. On laboratory dishes, these stem cells were found to be havens for viral reproduction, resulting in cell death and/or di... Read More

With about 10,000 new patients each year, occurrences of Lyme disease in Switzerland are amongst the highest in Europe, representing a substantial healthcare cost and threatening S... Read More
New research to be published January 13 in the journal Scientific Reports shows that some bacterial cultures adopt an all-for-one/one-for-all strategy that would make a socialist proud in preparing for the possibility of an antibiotic onslaught. Read More
