Abstract
In the present investigation, Dipylidium caninum infection was found to be 23.33 per cent on carcass examination, 0.56 per cent on faecal examination and 2.00 per cent of dogs were clinically positive for D. caninum gravid segments. Overall helminthic infection on the basis of carcass examination was 80.00 per cent and 25.55 per cent on faecal examination.
Different flea species Ctenocephalides canis, Ctenocephalides felis felis, Ctenocephalides felis orientis and Xenopsylla cheopis were recorded from dog, cat, mice, goat and cattle. Predominant species in dog was C. felis felis (48.93%) followed by C. felis orientis (40.42%) and C. canis (10.63%). In cat, C. felis felis (50.00%), X. cheopis (27.78%), C. canis (16.67%) and C. felis orientis (5.56%) were recorded. Rate of flea infestation was highest in dog (68.66%) followed by mice (62.50%), cat (24.00%), goat (20.00%) and cattle (13.33%).
Recovery percentage of cysticercoid from dog fleas were 0.65 per cent of which C. canis accounted for 0.26% and C. felis 0.39 per cent.
One species of dog lice Heterodoxus longitarsus was recorded during the study.
Experimental development of metacestode of D. caninum in laboratory bred flea larvae was partly successful under laboratory condition. There was mortality in C. felis felis larvae on exposure to D. caninum eggs in the trial.
