Salmonella:
New evidence discovered by scientists demonstrates that specialized intestinal cells control the ability of Salmonella to grow by restricting their access to essential metals, such as iron and manganese.Salmonella are a group of bacteria that can cause gastrointestinal illness and fever called salmonellosis.Salmonella bacteria are widely distributed in domestic and wild animals.They are prevalent in food animals such as poultry, pigs, and cattle; and in pets, including cats, dogs, birds, and reptiles such as turtles.Salmonellosis in humans is generally contracted primarily through the consumption of contaminated food of animal origin, although other foods, including green vegetables contaminated by manure, have been implicated in its transmission.Person-to-person transmission can also occur through the faecal-oral route.Human cases also occur where individuals have contact with infected animals, including pets.The illness usually lasts four to seven days, and most people recover without treatment.Treatment in severe cases is electrolyte replacement (to provide electrolytes, such as sodium, potassium, and chloride ions, lost through vomiting and diarrhoea) and rehydration.
