| dc.description.abstract | Chicken helminthiases are endoparasitic infection of chicken which are widely distributed throughout the world
and their presence has also been reported in Bangladesh including Sylhet. A cross-sectional study was
conducted from October 2015 to May 2016, to determine the prevalence and case-control study conducted to
identify the determinants of chicken helminthiasis. Faecal samples from 150 chicken flocks selected by using
simple random sampling scheme from four (4) different upazilas of Sylhet district. Faecal sample were
examined by Simple McMaster technique using flotation fluid saturated with NaCl and sugar. The data were
collected from survey using a well designed questionnaire. Prevalence were calculated as a proportion of
infected flocks in total number of flock tested. Multivariable logistic regression was used to identify the
determinants of chicken helminthiasis. Overall prevalence of chicken helminthiasis was 79.33%. Seven
nematodes: Ascardia galli, Heterakis gallinarum, Capillaria annulata, Capillaria columbae, Syngamus
trachea, Strongyloides avium and Trichostrongylus tenuis and three cestodes: Raillietina cesticillus,
Choanotaenia infundibulum and Hymenolepis carioca were found in the tested samples. Capillaria columbae
which is commonly known for nematode of pigeon, also found in chicken with prevalence of 16.66%. Among
four upazilas Biswanath (91.66%) were most prevalent while Jaintapur (58.33%) was low prevalent area of
Sylhet district. The present study identified four significant determinants namely anthelmintic used,
environment surrounding the flock, source of water and healthy and sick birds kept together, respectively. The
results of this study indicate that chicken helminthiasis is common in Sylhet district and this finding can be used
for the treatment and control measures for chicken helminthiasis. However, further investigation should be
needed in the study area. | en_US |
