| Abstract | ||||
| In this study, 512 milk samples from different sources were examined. The incidence of Listeria (L.) among the different ruminant species revealed the isolation of isolates where the percentage of Listeria isolation was 6.1%. The isolated Listeria spp. were distributed as 9 strains from cows, 8 strains from buffaloes, 6 strains from goats, 8 strains from ewes and 4 strains from she -camels raw milk. The Listeria spp. were related to 7 strains of L. monocytogenes, 4 strains L. innocua, 8 strains L. welshimeri, 7 strains L. seelegeri and 5 strains L. grayi in a percentage of 1.4%, 0.8%, 1.6%, 1.4% and 0.98%; respectively. The antibiogram for Listeria isolates revealed that all isolates showed resistance for the following antibiotics: cloxacillin, oxacillin, pefloxacin, flumoquine, cephalosporin, bacitracin, lincomycin, clindamycin. Listeria spp. consider as an important environmental and opportunistic pathogens for ruminant raw milk with some evidence for multidrug resistance strains due to miss use of antibiotics. | ||||
