Q. Show the Symptoms of salmonellosis?
Symptoms: The susceptibility of humans varies with the species and strains of the organism and the total number of bacteria ingested. A longer incubation period usually distinguishes salmonellosis from staphylococcus poisoning: usually 12-36 hours for the former and about 2-4 hours for the latter. The principle symptoms of a salmonella gastroenteritis infection are nausea, vomiting, abdominal pain and diarrhoea that usually appear suddenly. This may be preceded by a headache and chills. Other evidences of the disease are watery, greenish-fowl-smelling stools, prostration, muscular weakness, faintness, usually a moderate fever, restlessness, twitching and drowsiness. The mortality is less than 1%. Intensity may vary from slight discomfort and diarrhoea to death in 2 to 6 days. About 0.2 to 5.0% of the patients may become carriers of the Salmonella organism. During the acute phase of the disease, as many as one billion salmonellae can be found per gram of faeces.
