Prevalence and morphotaxonomic characteristics of nematode, Contracaecum travassosi (Gutierrez, 1943) from bird jungle babbler, Turdoides striata

The research study was conducted on the helminth parasite of bird Jungle babbler, Turdoides striata from district Naushahro Feroze, Sindh during, 2015-16. The total (n= 110) specimens were collected from (n= 48) birds that belonged to the genus; Contracaecum Railliet and Henry, (1912), were recovered from the anterior, median and posterior part of large intestine but mostly most of the helminth were found in terminal part of the large intestine of the host. Present specimens were observed in diverse form its congress, but having morphologically closely resemblance with Contracaecum travassosi, Gutierrez, 1943 which consists medium sized body. Prominent buccal capsule is along with developed inter labia but oesophagus was observed cylindrical and simple without bulb. Spicules were un-equals and they do not contain gubernaculum. Longitudinal sucker with a chitinous rim and vulva located at the little distance from the anterior region. Surrounding the tail region ten pairs of caudal papillae of which six pairs were postclocal, three pairs were Preclocal and one pair was paraclocal with tail pointed posteriorly. Female eggs had elliptical position and nearly rounded. The infections rate of parasites were found high during the hot summer season in the month of July when compared with contrast season (winter, cold season) specially with December and January. Such type of research study for the purpose to find out the helminth burden in the host Jungle babbler (Turdoides striata) was carried out first time. Therefore; it is suggested that, the lot of passeriformes birds contain variety of helminth parasites in their internal tract and organs, so it is strict need to carry out the systematic study of the parasite that logged the burden to their host birds
