Describe methods that can clarify weather salmonella isolates from a given food suspected of being a source of outbreak are identical to salmonella from patients who have become ill as a consequence of the outbreak

Answer 1

Salmonella infection:

Salmonella bacteria can cause two type of illness like the typhoidal and non-typhoidal infections.Typhoid fever, also known simply as typhoid, is a bacterial infection due to Salmonella typhi that causes symptoms.Symptoms may vary from mild to severe and usually begin six to thirty days after exposure.

• Typhoid fever is a systemic disease of varying severity. Severe cases are characterized by gradual onset of fever, headache, malaise, anorexia and insomnia.
• Constipation is more common than diarrhoea in adults and older children.
• Typhoid fever, also known as enteric fever, is a potentially fatal multisystemic illness caused primarily by Salmonella enterica,subspecies enterica serovar typhi and, to a lesser extent, related serovars paratyphi A, B, and C.
• The sources from the outbreak and the infected patients both showed the same infected substances and agents and virulent factors that cause the disease.
• An apparent outbreak can result from either incorrect diagnoses, multiple diseases with similar symptoms,or even changes in record keeping or surveillance practices.
• From the initial information of a possible disease outbreak we can describe how to determine whether an disease is a epidemic.
