Histopathological studies of tapeworm Raillietina tetragona (Molin, 1858) from the gastro-intestine of indigenous chicken (Gallus domesticus L.) farming in Kirtipur, Nepal

Author(s): Anil Kumar Jha
Abstract: Aim: Raillietina tetragona is a parasitic tapeworm belonging to the class Cestoda and found in the small intestine of chicken throughout the world. Thus a research was undertaken into Raillietina tetragona infection in scavenging indigenous chicken Gallus domesticus in the Kirtipur Municipality of Kathmandu Valley from March 2013 to April 2015.
Materials and Methods: A total of 225 birds of different age groups and both sexes were randomly selected from 10 different farms and screened through clinical, parasitological and pathoanatomical examinations. Photomicrography was conducted with DP-12 Digital Camera attached to Olympus Research Microscope in the department of Zoology.
Results: The Cestode R. tetragona recorded during the different seasons (spring, summer, autumn and winter) and it was highest 19. 64% parasites were recorded during autumn season while the infestations were as 18. 37, 9.59 and 8.51 in the seasons of summer winter and spring respectively. Physiological status, bird type, production purpose, farm age (years), level of 19. 64% biosecurity, and frequency of cleaning the pen were the risk factors significantly (p<0.05) associated with the presence of helminth infections.
Conclusion: This study shows that helminth infections are endemic in the study area, as 19. 64% of the sampled farms were infected with R. tetragona species. Findings from this study provide information that will assist in improving the poultry sector in Kathmandu in general, for better production and profitability.
