Abstract
Raillietina tetragona is an endogenous helminth parasite infecting domestic chick. In the present study, total proteins, soluble and insoluble proteins levels in immature, mature and gravid proglottids of Raillietina tetragona have been undertaken. The total proteins in immature, mature and gravid proglottids are 96.42 ± 1.8, 90.37 ± 2.1 and 62.16 ± 1.1 mg protein/g fresh weight respectively. Soluble protein levels are 48.95 ± 1.9, 46.57 ±1.0, 42.23 ±1.5 and insoluble protein levels are 52.37 ±1.5, 39.43 ±1.0, and 35.85 ±1.9 mg protein /g fresh weight respectively. The data obtained from immature, mature and gravid segments of adult worm supports the transition in proteins levels in relation to the differentiation of proglottids. The reason for higher protein content in immature region indicates rapid proliferation rate, as it is involved in strobilisation which in turn requires amplified metabolic activity. The same was observed for soluble and insoluble proteins too and the data was statistically analysed by ANOVA.
