词汇 | salmonella |
词源 | Salmonella. Salmon have no connection with Salmonella or salmonellosis. The latter is a form of food poisoning that can re- sult in death and is caused by bacteria of the Salmonella genus, comprising some 1,500 species. The Salmonella genus was first identified by 19th-century American pathologist and veterinar- ian Daniel Elmer Salmon, who died in 1914. There are often outbreaks of salmonellosis, which is usually caused by infected and insufficiently cooked beef, pork, poultry, and eggs, as well as food, drink, or equipment contaminated by the excreta of in- fected animals. Nearly all animals are hospitable to the rod- shaped bacteria causing the acute gastroenteritis in humans, and food poisoning caused by them are almost as common as those caused by staphylococci. Incidentally, there is a “salmon disease” dogs and other animals get from eating salmon infested with cysts of flukes, but it has nothing to do with salmonellosis. |
