    Isolation and identification of infectious agents in field rodents
    (CCSHAU, 2017) Neetu; Ravikant
    A study on population dynamics of rodents was carried out in dry land area from October to December, 2016 and the prevalence of zoonotic agents from field rodents trapped during the investigation. This study was revealed that population dynamics of Tetara indica was more as compare to Mus musculus, Rattus rattus and Funambulus pennati in all three month. Comparable with each other maximum population of T. indica during November. The rodents number was maximum in 1st week of three month and least in the 4th week during the investigation time period. Trap index was found highest in the October and least in the December, 2016. The study was also conducted to determine the bacterial isolates from the rodents that causes the zoonotic diseases. Total eight bacterial agents were isolates from the field rodent i.e. T. indica, R. ratuus and F. pennati. On the basis of secondary biochemical tests, Salmonella, Pseudomonas and Yersinia were more prevalent in rodent species, captured in dry land field. To determine the antimicrobial resistance occurs in various bacterial agents isolated from rodents. The bacterial isolates were analyzed for antimicrobial susceptibility to thirty six antibiotics. The bacterial isoletes no. TIN2 was found multidrug resistance (MDR) towards seven antibiotics (Cefixime, Cefpodoxime, Augmentin, Cefadroxil, Ceftriaxone, Cefpirome and Cefepime), FPN4 showed multidrug resistance (MDR) towards five antibiotics (Cefixime, Rifampicin, Augmentin, Cefuroxime and Ceftriaxone). FPN2 and FPN3 were found resistance against two separate antibiotics. It was found that all these isolates were found resistance to one or more antibiotics. Out of these, TIN2 and FPN4 which are great concern of matter to human and veterinary health. Thus rodents may be proving their role in spreading zoonotic diseases.
