RESUMO
A new disease condition has emerged affecting replacement pullets. It affects the birdsbetween 2 to 10 weeks of age. The mortality rate varies between 1 to 10% and ultimately the flock is left with creation of several small poorly feathered and pale chicks. Though it has not been possible to establish the exact cause of this condition, following three points has been taken in consideration. HPPGE is an illness that involves one or more infectious agents. The digestive tract and endocrine organs may be primary targets for this agents.The spectrum of signs or lesions are either caused by or exacerbated by nutritional, husbandry and hygienic factors. The response to the treatment is often poor but the symptomatic treatment has helped in ameliorating the mortality. Similar condition has been widely reported in broilers under various names like Malabsorption syndrome, infectious Proventriculitis, infectious runting syndrome, pale bird syndrome and stunting syndrome.
RESUMO
PCR detection of ‘stx 1’ and ‘stx 2’ toxigenic genes in multiple antibiotic resistant Escherichia coli population and Phenotypic detection of ESBL producing Escherichia coli isolated from traditional local variety of poultry was conducted The study revealed that out of 30 samples collected 20 were positive for E.coli All the 20 isolates were subjected for the detection of 2 toxin genes (stx1 & stx2 genes) by PCR. Only 3 isolates (L3, L4 & L5) gave rise to PCR product against its specific primers of stx1. All the isolates were negative for the presence of stx2 gene. Thus 15% of E.coli population under this study is potential isolates and indicates that healthy retail poultry birds are the carrier of E.coli pathogenic strains. The poultry birds may therefore, be considered as a major reservoir of E.coli.
