Salmonella
Salmonellosis is an infection with bacteria called Salmonella. Salmonella germs have been known to cause illness for over 100 years. The bacteria were first isolated in 1885 by Theobald Smith from pigs. The genus name was derived from the last name of D.E. Salmon, who was Smith's director. In 1896 Salmonella infection was diagnosed in humans. Salmonella is the genus name for over 2,500 types of bacteria. Though each type is closely related each is distinctly identifiable by its specific protein. Salmonella bacteria are known to cause disease in humans, animals, and birds throughout the world. The major diseases caused by Salmonella are gastroenteritis and typhoid fever (Davis, 2010).
According to the CDC (2010) approximately 40,000 cases of salmonellosis are reported in the United States each year. Since many milder cases are not diagnosed or reported, some estimate that the actual number of infections may be thirty or more times greater. Salmonella serotype Typhimurium and Salmonella serotype Enteritidis are the most common in the United States. Salmonellosis is more common in the summer than winter. It is estimated that each year approximately 400 persons die with acute Salmonellosis (CDC, 2010).
Transmittal of Salmonella
Salmonellosis is spread to people by ingestion of Salmonella bacteria through contaminated food. Salmonella can contaminate almost any food type; however outbreaks of the disease have involved eggs, raw meat, egg products, fresh vegetables, cereal, pistachio nuts, tomatoes,...
Salmonella Food-born illness Food-borne illnesses: Salmonella The salmonella bacterium is one of the most well-known and well-publicized health threats in the U.S. "Salmonella germs have been known to cause illness for over 100 years" (What is Salmonellosis, 2010, CDC). Salmonella bacteria can be present in the intestines of humans, and can be transmitted through consumption of tainted foods, water, or animal matter. Infections can be difficult to trace in the early stages, because
Salmonella Infection The salmonella bacteria had been the twentieth century’s archetypical organism causing food poisoning, highly notorious for the 1988-89 crisis of salmonella in eggs. By that time, however, it had already been a topic of scientific and public health focus for more than a hundred years. Previously linked to animal foods, phage typing’s introduction during the 1940s started revealing the complex nature of its associations with its environment (Hardy, 2004). Epidemiological
Salmonella Fig 1. Salmonella Bacteria The first thing to note about Salmonella (seen in Fig. 1) is that it is a bacteria, and therefore a living organism. However the term "Salmonella" is used loosely in daily conversation to specify an illness caused by that bacteria in humans, and in other animals. Most people have some vague recollection of a "salmonella outbreak" caused by a contaminated food supply being reported in the media,
Infectious Disease Salmonellosis Salmonellosis, named after pathologist Daniel S. Salmon who first isolated the organism from porcine intestine, was first described in 1880 and cultured in 1884 (Salmonellosis1 pp). Salmonellae are motile, gram-negative, rod-shaped bacteria of the family Enterobacteriaceae, and are common in the gastrointestinal tracts of mammals, reptiles, birds, and insects (Salmonellosis1 pp). Salmonellae are potential enteric pathogens and a leading cause of bacterial food-borne illness (Salmonellosis1 pp). With a single overarching
Heightened temperature (fever) is almost always apparent, and diarrhea is another nearly-universal symptom other possible symptoms of an equine salmonella infection include a loss of appetite, colic, depression, and in some instances certain ulcers and bloating (Johnson 2010; Lane et al. 1992). Most cases of salmonella present only some of these symptoms, rather than all of them, and most of the symptoms are located (as might be expected) along
