ABSTRACT
The epidemiological study of gastrointestinal parasites was carried out in unorganized sheep farms in aeolian plains of Haryana from March, 2018 to February, 2019. A total of 1080 faecal samples were examined, out of which 899 (83.24%) were positive for helminthic infections. The different helmiinths observed were strongyles (80.93%), Strongyloides spp. (28.24%), Trichuris spp. (7.31%) and Moniezia spp. (1.02%). Infection was non-significantly higher in adults (83.34%) as compared to young (76.67%). Males showed a non-significantly higher infection (89.79%) as compared to females (82.59%). Significantly higher (p<0.05) infection was observed in monsoon (98.88%) as compared to winter (74.17%), spring (78.88%) and summer (82.72%) season. Significantly higher (p<0.05) infection (100%) was observed during month of August and September while lowest infection was observed during month of November (56.67%). Coproculture studies revealed that Haemonchus contortus was predominant parasite during all the seasons, followed by Strongyloides spp., Trichostrongylus spp. and Oesophagostomum spp. No trematode eggs were identified during study period
ABSTRACT
The present study was conducted to detect the status of anthelmintic resistance of fenbendazole and morantel against gastrointestinal nematodes in goats of village Badhra, district Charkhi dadri, Haryana. Forty five goats with eggs per gram of more than or equal to 150 were divided into three groups i.e. G1, G2 and G3 of 15 animals each. Group G1 and G2 were treated with fenbendazole @ 10 mg/kg b.wt. orally and morantel @ 20 mg/ kg b.wt. orally, respectively. Group G3 served as untreated control. Faecal egg count of goats was ascertained on day of treatment (0 day) and 12th day post treatment (PT) of all groups by the modified McMaster technique. Pooled faecal cultures were made to recover infective larvae on day 0 and 12 PT. Results revealed that fenbendazole (G1) and morantel (G2) reduced the faecal egg counts by 76.47% and 70.80% on 12th day PT with upper and lower confidence levels as 89.30% and 48.23% and 82.43% and 51.48%, respectively indicating moderate anthelmintic resistance against both drugs. The post-treatment coproculture showed larvae of Haemonchus contortus and Strongyloides sp. Thus, the present study revealed presence of cross anthelmintic resistance against fenbendazole and morantel in goats of unorganized sector in Charkhi Dadri district of Haryana
ABSTRACT
The present study was conducted to detect the status of anthelmintic resistance of commonly used anthelmintic drugs viz. fenbendazole and morantel against gastrointestinal nematodes in sheep of village Badhra, district Charkhi dadri, Haryana. Forty five sheep with egg per gram of more than or equal to 150 were divided into three groups i.e. S1, S2 and S3 of 15 animals each. Group S1 and S2 were treated with fenbendazole @ 5 mg/kg b.wt. orally and morantel @ 10 mg/ kg b.wt. orally, respectively. Group S3 served as untreated control. Faecal samples were collected on the day of treatment (zero day) and 12th day post treatment (PT), from sheep of all groups and individual FEC were determined by the modified McMaster technique. Pooled faecal cultures were made to recover infective larvae on day 0 and 12 PT. Results revealed that fenbendazole (S1) reduced the FEC by 74.77% on 12th day PT with upper and lower confidence levels as 86.41% and 53.15%, respectively indicating moderate anthelmintic resistance. Morantel (S2) caused 49.84% reduction in FEC with upper and lower confidence levels as 65.04% and 28.04%, respectively indicating severe anthelmintic resistance. Thus, the present study revealed presence of cross anthelmintic resistance against fenbendazole and morantel in Haemonchus population in sheep of unorganized sector in Haryana as the post-treatment coproculture showed only Haemonchus contortus larvae
