Nasal drops of harmless bacteria can inhibit a related bug that sometimes causes meningococcal disease, according to new findings published online in Clinical Infectious Diseases. The study--conducted among college students, a group at higher risk for this often serious illness--suggests a new a... Read More

Some holiday fun from last winter composed of different collected plate contaminants. Based on colony morphology and wet mounts, these bacteria are likely to be: Staphylococcus sp. (white), Serratia marcescens (dark orange), and Micrococcus luteus (creamy yellow). The design was incubated for 5-... Read More
Starch agar contains high molecular weight starch molecules (soluable starch). When Iodine is added it reacts with starch to produces a dark brown/purple color. A zone of clearing forms around organisms that produce the exoenzyme amylase after addition of iodine. This plate was incubated for ... Read More
Could a fist bump be a cleaner, better way for people to greet each other, especially in germy hospitals? British researchers have done an experiment that seems to say yes.
They tested just how many bacteria are transferred hand to hand during a handshake, a high-five and a fist bump. Handsha... Read More
