An Overview on Bacterial Antimicrobial Resistance

T he current investigation directed to assess the effectiveness of commercial disinfectants (disinfectant I, sodium hypochlorite 400 ppm and disinfectant II, quaternary ammonium compound (QAC) 3 %) at inactivating field C. sakazakii strains previously isolated from diarrheic stool (A) and fresh cow milk (B) in watery suspension (planktonic cells) and that dried after being injected on stainless steel coupons.The results proved that, both disinfectants I and II had inhibitive effect on tested C. sakazakii strains in watery suspension and that inoculated and dried on stainless steel coupons with significant reductions (P 0.05) in populations compared to the number of cells recovered from control and QAC was more potent than disinfectant I on tested C. sakazakii strains; the strain A was more resistant to these disinfectants than strain B and the longer the treatment time the more effectiveness of disinfectants.Therefore, it was concluded that; the routinely pre-rinsing ,cleaning and sanitization of equipment in dairy farms, milk collector centers and dairy processing plants with QAC 3 % disinfectant is the most crucial stage in managing the route of infection, spreading and contamination with C. sakazakii pathogens to avoid their public health hazards.
