| dc.description | The poultry industry has been successfully becoming a leading industry of Bangladesh. The
primary objective of the study is to identify the constrain that hampers the expansion and
sustainability of poultry industry in Bangladesh. In the last few years, the recognition of small-scale
commercial poultry production helps to accelerate the pace of poverty reduction riding in new
height in Bangladesh. Considering the importance of the country's poultry industry in order to
ensure the sustainable economic development it is now high time to step forward for the better
accumulation of resources available from this industry. This industry proves various opportunities of
increasing GDP growth rate plus equitable distribution through arranging food security as well as
ensuring self-employment at a large scale. (Moulude et al, 2012) | en_US |
| dc.description.abstract | The present research work was carried out to the study of isolation and identification of the
etiological agent of Staphylococcal infection in commercial broiler flock having typical symptoms
with antibiogram study and extraction of toxin from field isolate and determination of lethal effect of
toxin in day old chicks. The sample (pus/fluid) were collected from the suspected birds and shifted
aseptically to the Bacteriology laboratory of the Department of Microbiology, Hajee Mohammed
Danesh Science and Technology University, Dinajpur. The samples were subjected to
bacteriological examination for isolation and characterization of bacteria. Locally available
antibiotic discs were used for determining the degree of drug sensitivity against the
Staphylococcus isolates. The study shown that the highest percentage of occurrence (52.17%) of
Staphylococcus aureus was obtained from group A followed by group B (41.67%) and group C
(20.0%). Prevalence of toxicity in case of day old chick those were given toxin orally was 30% and
in case of chicks those were inoculated subcutaneously was 10%. Out of 30 day old chicks 04
died and average prevalence of toxicity is 20%. In postmortem examination it was found that
tenosynovitis, most commonly in the plantar area of the foot or just above the hock joint. This was
progress to abscess formation in these areas. Infected joints had clear exudate with fibrin clots.
The abdomen felt soft, mushy, flabby and enlarged. Lesions associated with heavy challenge of
infection generally consist of congestion of internal organs, including the liver, spleen, kidneys, and
lungs, accompanied by areas of tissue death. The staphylococcus aureus highly sensitive to
different antimicrobial agents such as 100% sensitive to Ciprofloxacin, Doxycycline, Penicillin,
Gentamicin; 70% sensitive to Nitrofurantoin; 60% sensitive to Azithromicin and resistance to
Cephradine, Ampicillin, Amoxicillin, Sulfomithoxazole X Trimethoprim. | en_US |
