Salmonellosis is an infection caused by Salmonella bacteria. Most people infected with Salmonella develop diarrhea, fever, vomiting, and abdominal cramps 12 to 72 hours after infection. In some cases, the diarrhea may be so severe that the patient becomes dangerously dehydrated and must be hospitalized.Symptoms of salmonellosis include diarrhea, fever, and abdominal cramps. They develop 12 to 72 hours after infection, and the illness usually lasts 4 to 7 days.
Salmonellosis is diagnosed based on a medical history and a physical exam. A stool culture and blood tests may be done to confirm the diagnosis. Most people don't need to seek medical attention for a salmonella infection because it clears up on its own within a few days. However, in cases involving infants, young children, and older or immunocompromised adults, is associated with high fever or bloody stools, or appears to be causing dehydration.
The Swedish control of Salmonella, with special reference to Salmonella enteritidis, in poultry is described. The control is directed at all serotypes of Salmonella and imported grandparent chickens are controlled, which is considered to be the main reason why Sweden so far is not found to be involved in the worldwide spread of different phagetypes of S. enteritidis. However, this spread has initiated a more stringent control of Salmonella in layers as earlier existed in broilers. Since 1990, 90% of the layer flocks are voluntarily tested for Salmonella before slaughter by bacteriological examination of pooled faecal samples.
The National Salmonella and E. Coli Centres are involved in identifying and typing Salmonella spp. and E. coli from within India and around the world.
