The species of nematodes collected from pigeons were Ascaridia columbae, Capillaria obsignata, Ornithostrongylus avium. Capillaria obsignata had the highest prevalence.
The development of egg and the time taken to reach the infective stage in egg cultures of Ascaridia galli, Heterakis gallinae, Syngamus trachea, Ascaridia columbae, Capillaria obsignata and Ornithostrongylus quadriradiatus maintained at different room temperature were studied and recorded.
The cross transmission trials with fowl nematodes ;
A. galli, H. gallinae and S. trachea and pigeon nematodes ;
A. columbae, C. ogsignata and O. quadeiradiatus were conducted in pigeons and chicks respectively. Syngamus trachea and C. obsignata were found to be transmissible between pigeons and chicks.
The detailed life cycles of A. columbae, S. trachea and O. quadriradiatus in pigeons were worked out in detail. The prepatent period for these species was 46, 28 and 7 days respectively.
The infective larvae of O. quadriradiatus were seen to be phototrophic and hydrotactic. They remained viable for 47 to 52 and 60 to 67 days in dry and wet seasons respectively.
The clinical signs, gross and histopathological lesions produced by the nematodes in pigeons were recorded. Moderate infection of O. quadriradiatus produced anaemic changes in pigeons.
