ABSTRACT

A total of 50 Salmonella isolates belonging to different serovars viz., S. Typhimurium (21), S. Weltevreden(12), S. Ughelli (5), S. Essen (3), S. Elisabethville (2), S. Lagos (2), S. Drogana (2), S. Enteritidis (1), S. London (1)and un-typable Salmonella-isolate (1) were recovered from 1,132 samples originating from man, animals and foods of animal origin. The most prevalent serovar was S. Typhimurium followed by S. Weltevreden. The emerging Salmonella serovars viz., S. Elisabethville, S. Essen, S. Lagos, S. Ughelli and S. Drogana were recovered for the first time from different sources from Pantnagar and its vicinity. S. Drogana was recovered from human stool sample, which is possibly the first isolate from human source in India. Multiple Salmonella serovars (S. Typhimurium, S. Weltevreden and S. Essen) were recovered from a single cattle dung sample while, mixed infection was also recorded in single sample source of cattle dung (S. Weltevreden and S. Ughelli), poultry droppings (S. Essen and S. Ughelli), pig faeces (S. Weltevreden and S. London), sheep faeces (S. Typhimurium and S. Drogana) and pig faeces (S. Weltevreden and S. Ughelli). The high prevalence rate of Salmonella was recorded in faeces of sheep, poultry, pig, buffalo, cattle, autopsied poultry tissues, poultry eggs, pork, poultry meat and human beings as 27.27%, 8.33%, 3.7%, 2.91%, 2.86%, 26.67%, 2.04%, 1.28%, 0.94% and 0.65%, respectively.
