The ''Vibrio cholerae'' exotoxin is part of a group of bacterial toxins referred to as A/B toxins, owing to the presence of 2 subunits. The toxin is responsible for the massive, watery diarrhea characteristic of cholera infection. It acts by causing ATP-mediated efflux of chloride ions into the gut lumen. The ''Vibrio cholerae'' exotoxin is usually inactivated by heating at 60 °C (140 °F) for several minutes. +
Renal artery stenosis is a common cause of secondary hypertension. It is an atherosclerotic condition that eventually leads to renal failure due to renal hypoxia and inadequate nutrition of renal parenchymal cells caused by the stenotic artery. Atherosclerosis in the renal artery is almost always observed in the proximal to mid portion; in contrast to FMD which mostly occupies the mid to distal regions. +

The majority of cases of ''M. pneumoniae'' infections occur during the late Summer or early Fall period. Transmission is via aerosols; and at-risk settings include schools, military barracks, and healthcare institutions. Clinical presentation usually includes gradual worsening of symptoms, which may persist for several days or weeks: Fever, pharyngitis, intractable dry or mildly productive cough, and dyspnea (in severe cases). +
