Bacteriological studies on native and imported apparently healthy one day old chicks

Abstract

One thousands and eighty one day old chicks were examined for isolation of different bacteria. Salmonella was detected in 11.7% in native chicks while 5.2% among imported chicks, E. coli was isolated from 17.6% in native chicks while 23.6% in imported, Staph aureus was present in 29.4% in native and 5.2% in imported chicks. Serological typing of Salmonella was Salmonella Norwich, Salmonella Wilhelburg in native chicks while in imported chicks were Salmonella Brancoster, Salmonella Sekondi II. E .coli serotyping reveled O125, O153, O86a in native chicks while in imported chicks were O26, O78, O36, O15, O124, O169, O6, O28 and one untypeable strain. Seven Staph aureus isolates five from native and two from imported. Antibiogram of isolated bacteria was done. All Salmonella strains were sensitive to Gentamycin while all E. coli strains were sensitive to Amoxicillin + Clavulanic acid and Nitrofurantoin. All Staph aureus isolates were sensitive to Amoxicillin + Clavulanic acid. .

Antibiotic resistance and extended-spectrum β-lactamase in Escherichia coli isolates from imported 1-day-old chicks, ducklings, and turkey poults

“…The resultant therapeutic failures have turned into a worldwide problem [ 35 ]. In Europe, bla CTX-M , bla TEM , and bla SHV have been recorded as the most predominant ESBL genes in compared with ampC [ 36 ]. Reports discussing the prevalence of ESBL-producing E. coli isolates from imported 1-day-old flocks in Egypt are scarce.…”
