Salmonella tphimurium DT104

In News 
  • Recent studies have found the emergence of multi-drug resistant Salmonella tphimurium DT104 that causes infections in humans and cattle.
Salmonella 
  • They are gram-negative bacteria(containing double cell walls). Hence they are highly resistant to antibiotics.
  • Most infections are due to the ingestion of food contaminated by animal faeces or by human faeces, such as by a food-service worker at a commercial eatery.
  • Two main groups—typhoidal and nontyphoidal
  • Nontyphoidal serotypes are zoonotic and can be transferred from animal to human and from human to human. They usually invade only the gastrointestinal tract
  • Typhoidal serotypes can only be transferred from human to human and can cause food-borne infection
  • Recent studies reported an annual incidence of as many as 360 cases of typhoid fever per 1,00,000 people, with an annual estimate of 5 million cases and 8,930 deaths (0.2% fatality rate) in India.
