Prevalence of different salmonella serovars in india up to 2005

This short presentations reveals the prevalence of different Salmonella serovars in India in Animals based on the serotyping of >4000 isolates of Salmonella submitted to National Salmonella Centre up to 2005. It may be helpful in understanding salmonellosis in India to some extent.

Indian Veterinary Research Institute, Izatnagar-243 122 INDIA Analysis and compilation By Dr. Bhoj R Singh, Principal Scientist (VM) I/C Epidemiology; Centre for Animal Disease Research and Diagnosis Indian Veterinary Research Institute, Izatnagar-243122, Bareilly, UP, India.

  • 2. SALMONELLA IN INDIA Salmonella and salmonellosis are prevalent all over the world including the most developed as well as the poorest countries. Salmonellosis is a hyperendemic disease in India in humans and probably in animals too. There are >2500 serovars of Salmonella distributed all over the globe. Of these about 231 serovars have been reported in India, 25 exclusively in human and equal number in animals rest have been isolated from varied sources. To start any disease control programme a country need to understand the epidemiology of the disease and for salmonellosis serotyping is of utmost significance.

On the basis of overall prevalence, major Salmonella serovars of zoonotic significance are   S.Typhimurium, S. Bareilly, S. Newport, S. Weltevreden, S. Saintpaul and S. Enteritidis are the most prevalent wide host range Salmonella . S. Weltevreden, S. Senftenberg, S. Saintpaul, S. Havana and S. Chester are prominent emerging zoonotic Salmonella in last decade.  S. Typhimurium and S. Paratyphi A prevalence is on down-roads. S. Typhi, a strict host adapted Salmonella of human being has been isolated from sick as well as healthy Camel, Sheep, Cattle, Goats, Pigs, Birds and Rodents as well. S. Saintpaul is emerging as new zoonotic pathogen in foods of animals and vegetable origin. S. Typhimurium is still the leading serovar of zoonotic significance in India. Prevalence of S. Abortusequi is rapidly falling in equines and it is being replaced by other serovars, different in different parts of the country. After poultry and poultry product vegetable foods appeared to be the major emerging source of Salmonella. Host range of host restricted Salmonella serovars is widening. • S. Anatum has adapted to Indian buffaloes, however S. Weltevreden is the important • • • • • • • • • zoonotic serovar often isolated from buffen (Buffalo meat)
