The pathogen Escherichia coli O157:H7 can spread, likely airborne, more than one tenth mile downwind from a cattle feedlot onto nearby produce, according to a paper published ahead of print in Applied and Environmental Microbiology. The high percentages of leafy greens contaminated with E. coli ... Read More
Vincent and Dickson discuss how malaria parasites induce odors in their rodent hosts that attract mosquitoes.

Vincent and Dickson discuss the exchange of messenger RNAs between a parasitic plant and its hosts.
A fun little read about lichens and their impressive attributes, accompanied by some beautiful photographs. (If the use of the term "kingdom Monera" gives you cause to smirk, just ignore it and keep reading.) Read More

E. coli was grown on MacConkey Agar (MAC) at 37 degrees for 24 hour. MAC is a Selective and Differential media used to inhibit G+ growth and some G- bacteria as well as identify and isolate lactose fermenting G- enteric bacteria mainly Enterobacteriaceae. Strong lactose fermentation produces pi... Read More
