Abstract
The utilization of antimicrobial drugs has an important effect in chicken husbandry as they are used in prophylaxis, treatment and growth enhancement made poultry a major reservoir of antimicrobial-resistant bacteria. Therefore, our study was undertaken to isolate and control the most common bacterial contamination. For this purpose a total of seventy samples from raw chicken meat and organs (livers, hearts, spleens, muscles, kidneys, skin and gizzards) were collected from different retail markets and abattoirs in Sharkia governorate, Egypt. Nutrient agar was used for the total bacterial count (TBC) , mannitol salt agar for the total Staphylococcus count (TSC) and macConkey’s agar for the total Enterbacteriacae count (TEC). The most common bacteria were identified as Staph. aureus, E.coli and Salmonella isolates in an incidence of 8.57%, 35.7% and 4.28% respectively. The percentage of resistant bacteria to the tested antibiotic were77.8%, 85.7% and 71.4% for Staph. aureus, E.coli and Salmonella respectively. The most effective aquatic plant extract was clove followed by rosemary for its antibacterial effect. The silver nanoparticles has been synthesized and recognized by the color change and UV measurement after incubation of silver nitrate and watery extract of clove at dark conditions, it clearly showed complete inhibitory effect against all the tested MDR bacteria.
