    Isolation and characterization of zoonotic agents from field murids
    (CCSHAU, 2017) Anju; Ravikant
    Studies on the population dynamics of murids in vegetables field (bottlegourd and bittergourd) revealed that murids population was highest in bottlegourd during harvesting season (29.81%) followed by bittergourd harvesting (27.01%), bottlegourd sowing (22.77%) respectively in December, 2016. In bittergourd sowing least population (20.37%) was observed in September, 2016. Rattus rattus was the preponderant species in both crops followed by Mus musculus, Tatera indica respectively. Trap index was recorded highest in 3rd week (4.32) followed by 2nd week (3.96) and 4th week (3.55) during harvesting of bittergourd while in case of bottlegourd harvesting trap index in 3rd week (5.56) which was followed by 2nd week (4.01) and 4th week (3.55) in December, 2016. Total eight bacterial agents were isolates from the field rodent i.e. R. rattus, M. musculus and T. indica. On the basis of secondary biochemical tests, Salmonella, Pseudomonas and Yersinia were more prevalent in murid species, captured from vegetables field. For determination of antimicrobial resistance, disc diffusion test was performed. The bacterial isolates were analyzed for antimicrobial susceptibility to thirty six antibiotics. RRA3 was found multidrug resistance (MDR) towards Cefixime, Cefpodoxime, Augmentin, Cefadroxil, Ceftriaxone, Cefpirome and Cefepime. The bacterial isolate RRA4 was found MDR against Cefepime and Ceftriaxone. The bacterial isolate RRA5 was found MDR against Cefixime, Cefpodoxime, Ceftriaxone, Rifampicin, Cefuroxime and Cefepime. Four bacterial isolates from field murids were found multi drug resistant. Hence, the need of hour is to manage them in judicious manner.
