Streak plate of Proteus vulgaris. The plate was incubated at 37 degree C for 48 hrs then held at room temperature for 1 week. Swarming, white growth with finger like projections at the outer edges, around the circular solated colonies, circular white/beige opaque colonies, was not seen until ... Read More

New recommendation encourages physicians to prescribe _antibacterials_ instead of antibiotics for bacterial infections. This recommendation is based on compelling evidence that the word "antibiotic" confuses almost everyone, including some doctors. The confusion leads to strong patient demands... Read More
This montage of tiny, transparent C. elegans—or roundworms—may offer insight into understanding human infertility. Researchers used fluorescent dyes to label the worm cells and watch the process of sex-cell division, called meiosis, unfold as nuclei (blue) move through the tube-like gonads. Such... Read More
When the Ebola virus outbreak erupted in West Africa in 2014, children infected with the virus -- particularly those under age 5 -- faced overwhelming challenges. Not only was there a high death rate among young children infected with the disease, they often were isolated from their families, le... Read More
Four intracellular Toxoplasma gondii parasites are shown undergoing cellular division by an internal budding process known as endodyogeny. Staining with a T. gondii surface antigen provided heart-shaped images (shot on Valentine’s Day). The definitive host of these parasites is the cat, but they... Read More

These checklists, scrawled in handwriting on paper pasted to the hospital wall, are used by volunteer doctors and nurses to diagnose and treat patients who come in with symptoms of malaria and typhoid. Both are diseases that we rarely see in the US, but are strikingly common in Haiti. This also ... Read More
Methylobacterium aquaticum strain NO00 (KR920749) grown over rice grain. It can produce phytohormones and other beneficial metabolites for the plant. M. aquaticum is a plant growth promoting (PGP) bacteria". Its pink-biofilm, can help with water-stress and protect the plant against pathogens. Read More
Large TSA plate: yellowish organism is Staph aureus, red organism is Serratia marcescens. Grown for 24 hrs at 37 degrees C. Read More
A gene that lets bacteria resist polymyxins—the last line of antibiotic defense we have left—has shown up in widespread bacteria samples from pigs and patients in south China, including strains with epidemic potential. Read More
Shown here is a picture of a hookworm egg found on a concentrate in an ova & parasite exam
Human hookworms include the nematode species, Ancylostoma duodenale and Necator americanus. These species have indistinguishable eggs and can only be distinguished by their larvae.
Infective larvae g... Read More
