Nitrosomonas spp.

Nitrosomonas spp. - gram negative, aerobic, rod prokaryote. Magnification 2200, scanning electron microscopy. An obligate chemolithotrophic, nitrifying bacterium that oxidizes ammonia to nitrite (first step in two step process of nitrification).

Infectious bronchitis virus

Digitally-colorized transmission electron microscopy (TEM) image of a number of infectious bronchitis virus (IBV) virions. This enveloped pathogenic virus belongs to the Coronaviridae family and causes infectious bronchitis (IB) in poulty. This virus is very contagious through trasmission via air and contaminated material (food, water, supplies). It has a short incubation period. Entire flocks can be infected within days. The disease affects a number of organ systems including respiratory, gut, reproductive and urogenital organs.

If scientists have their way, “green” beer won't be limited to St. Patrick's Day celebrations anymore. Breweries are taking their wastewater, which is rich in organic material, and turning it into electricity with bacteria in microbial fuel cells (MFCs). MFCs can generate valuable commodities from a variety of organic wastes that are abundant and essentially free—bacteria have generated electricity from industrial wastewaters, sewage, and even sediment.

This bacteria is a gram-positive spore-forming anaerobe. This organism causes diarrhea and intestinal conditions like colitis (inflammation of the colon). It is the most frequent cause of infectious diarrhea in hospitals and long-term care facilities in industrialized countries. Infection is spread via feces contaminated surfaces (surface - mouth). Symptoms include fever, nausea, abdominal pain, loss of appetite and watery diarrhea.
