Abstract
The increasing prevalence of antimicrobial resistance in meat-producing
animals, especially ruminants, represents a major problem for human and animal and
also could increase the patient's morbidity and mortality. The gallbladder may be a sit
of persistence and a source for fecal shedding of certain enteric food-borne pathogen
resistant to many antimicrobial agents. In the current study 80 samples (32 bile, 48
epithelium) were examined to isolate the enteric pathogen;AII samples were cultured
on primary and selective. The frequency of isolation of microorganisms was (60% )in
the epithelium and (40% ) in the bile. The major pathogen isolated were (68.57%)
Proteus spp. (21.25%)E-coli ,(7.5)Citrobacter ,(1.25) Psudomnas.
and(1.25)Klebsiella.The antibiotic resistance was determined by Kirby-bauer disc
diffusion method using 10 of routine and practical antibiotics. In antimicrobial testing
from both bile and gallbladder epithelium showed sensitivity to the following
antimicrobial :amikacin, cefoxitin, chloramphenicol, gentamycin, kanamycin and
ciprofloxacin.
In conclusion , the current study provide helpful insights into the prevalence of food
source pathogens. High level of antibiotic resistance in proteus spp and Ecoli that
could transmit to humans through meat and meat products need for monitoring
system on the incidence and antimicrobial susceptibility of enteric pathogens in meat
animals in slaughterhouses.
