Abstract
Aim:
The present study was designed to study antibiotic
resistance profile of E. coli isolates from
colibacillosis in layers in and around Pantnagar.
Materials and Methods: A total of 20 isolates of
E. coli were recovered from 35 cases of
colibacillosis in layers during necropsy.
Antibiogram was studied via disc diffusion method
against 12 antibiotics.
Results: Results
showed multiple drug resistance in 52.63% E. coli
isolates. Serotyping of these isolates revealed
10 'O' group serotypes, predominantly O80 and O84
accounting for 31.57%. O80, O110, O119 and O132 have
previously been isolated from human suggesting its
zoonotic importance. A high degree of resistance was
seen against cephalexin (73.68%) whereas
chloramphenicol was found to be maximally (100%)
effective. Emergence of enhanced mechanism of
resistance to a variety of frequently used
antibiotics is an increasing public health problem.
Conclusion: It can be concluded that animals
and human are at potential risk of acquiring
infection with multi drug resistant strain of E.
coli.
