Abstract/ Executive Summary:

A total of 60 pigeon, Columba livia (25 males and 35 females) were examined to observe helminth parasite infection. All the birds were found to be infected by eleven species of helminth parasites: four species of trematoda: Echinostoma revolutum (15%) E. trivolvus (5%), Patagifer bilobus (5%), Ehinoparyphium recurvatum (8.33%); six species of cestoda: Hymenolepis columbae (63.33%), Raillietina echinobothrida (100%), R. bonini (43.33%), R. cesticillus (100%), Cotugnia celebesensis (68.33%), C. cuneata (100%); and one species of nematoda: Ascaridia columbae (28.33%). Females showed slightly higher intensity of infestation than the males. Trematode parasites were found in intestine and rectum, cestode parasites were found in duodenum and intestine, nematode parasite Ascaridia columbae was found in caeca. Oesophagus, crop, proventriculus, gizzard, gallbladder, liver, kidney and muscles were free of parasites. Considering among seasons highest intensity of infection was found in autumn

Location: Dhaka University

Start Date: 00-02-2010

End Date: 00-01-2011

Program Area: Pest Management

Commodity: Pigeon

Objectives:

To investigate the occurrence, prevalence, intensity, organal distribution and seasonal infestation of helminth parasites of pigeon

Methodology:

A total of 60 pigeon (25 males and 35 females) were randomly collected from February 2010 to January 2011. The pigeons were examined at the parasitology laboratory of Zoology Department, Dhaka University. The separated parts of the alimentary canal of the pigeons were taken in 0.85% normal saline solution to collect helminth parasites. Binocular dissecting microscope was used to detect and collect parasites. The trematode, cestode and nematode parasites were fixed with AFA solution and preserved in 70% alcohol. Before preparing permanent slides the parasites were removed from alcohol and cleaned in lactophenol. A suggestive method was used for the fixing, clearing and staining of the worms (Cable 1963). The collected helminths were identified according to Yamaguti (1958, 1959 and1961). Prevalence of individual parasite species was calculated as a percentage of the host population that was infested with a specific parasite at a point in time (Thrusfield 1995). Intensity was calculated as number of parasites per infected birds

Achievement/Findings:

Females showed slightly higher intensity of infestation than the males. Trematode parasites were found in intestine and rectum, cestode parasites were found in duodenum and intestine, nematode parasite Ascaridia columbae was found in caeca. Oesophagus, crop, proventriculus, gizzard, gallbladder, liver, kidney and muscles were free of parasites. Considering among seasons highest intensity of infection was found in autumn
