A recent study shows that consumption of unpasteurized milk significantly increases the risk of food-borne illness, which can be severe or even fatal in some cases. The scientific consensus points to a lack of knowledge of the 'benefits' of consuming raw milk, and an abundance of peer-reviewed... Read More
The antibiotic Colistin, which was approved in the 1950's, is now being used as a 'last resort' against multidrug-resistant Gram-negative bacterial infections, despite its nephrotoxic potential. The study, conducted by an international team of NIAID-funded researchers, found that the drug remai... Read More
Fungal contaminant on TSA grown at refrigerated temperatures for 1 month. Colonies appeared rhizoid throughout with a fluffy appearance. Read More
Different view of TSA plate with fungal contaminant, presumably from the air, after 1 month at refrigerated temperatures. White center spore formation can be seen with white hypae on the edges. Spore formation can be see forming towards the edges. Read More
The fungus Candida albicans, which can be fatal in up to 40% of patients with a systemic infection, is being reconsidered by a team of researchers from the University of Toronto. They investigated alternative explanations to the previously accepted thought that the fungus undergoes a change in ... Read More
