When treated with the prescription drugs Zoloft and Vascor, mice infected with Ebola survived.
The new study was small and preliminary, but if the drugs prove effective in humans—a finding still years away—it could mean new treatments for the deadly disease. Read More

Weaker organisms can prevail against stronger ones—if they’re superior in number, experiments show. This acts as a driving mechanism in the maintenance of genetic diversity. Read More
CAMP test - A presumptive identification of group B beta-hemolytic streptococci.
This a positive CAMP test indicated by the formation of an arrowhead where the Strep group B meets the Staphylococcus aureus (white middle streak).
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

E. coli growth on EMB Agar. EMB Agar slightly inhibits gram-positive bacteria due to the combination of dyes and is a selective and differential medium for coliforms. Bacteria that ferments lactose will exhibit a green metallic sheen. This image represents E. coli as a quality control microorga... Read More
