Gastrointestinal (GI) parasitism in animals is one of the major problems in India causing emaciation, anaemia, oedema, weakness, diarrhoea and death. Present study was designed to generate epidemiological data on GI parasitism of goats of Madhya Pradesh, India. During 8 months study period, a total of 960 samples were collected and examined by sedimentation

The coproculture study on Strongyle infection of goats was carried out in small holder farmers kept under semi-intensive management system in Balaghat, Narsinghpur and Chhindwara district, Madhya Pradesh, during the period from July 2011 to February 2012. Copro-culture of the samples positive for Strongyle infection revealed Haemonchus sp., Trichostrongylus sp., Oesophagostomum sp., Strongyloides sp., and Bunostomum sp. in a decreasing order in goats. The larvae of Haemonchus sp. (61.63 %) and Strongyloides sp. (7.50 %) were highest in Balaghat, Trichostrongylus (18.13 %) in Narsinghpur, while Oesophagostomum sp. (10.50 %) and Bunostomum sp. (5.75 %) were in Chhindwara district. The finding of this study indicates that, even though subclinical in nature, Strongyle infection are one of the major problems that could hamper health and productivity and there is need for design a programme to minimize and control Strongyle infection in goats in the study area.

Efficacy of chlorpyriphos (Classic*20, 20% EC) and deltamethrin (Butox, 1.25% EC) was assessed by spraying these drugs on cattle and buffaloes which were naturally infested with ticks at the concentration of 2.5 and 2 ml/l, respectively. Results of the study demonstrated the prolonged effect of chlorpyriphos when compared with deltamethrin. Moreover, residual effect of chlorpyriphos remained even after 14 days of treatment with 28.57% animals showing reinfestation, while in deltamethrin treated animals; the tick number started increasing after 14th day of treatment with 50% animals showing reinfestation on 14th day post-treatment.

Background: Benzimidazole resistance is one of the key problem in small ruminant production. A rapid, truthful and responsive system is required for detection benzimidazole resistance so that proper regulatory measure can be applied. Allele specific PCR is one of the tools to understand the mechanism and origin of benzimidazole resistance. Methods: A total 198 larvae of Haemonchus contortus were isolated from goats of Chhattisgarh region, central India were genotyped by allele specific polymerase chain reaction (AS-PCR). Faecal samples of goats were collected from three Government farms and adjoining field goats and were subjected for faecal culture, separately. DNA of third stage larva was used for nested PCR for amplification of β- tubulin gene. Restriction Fragment Length Polymorphism (RFLP) was applied on nested PCR product for species identification with RsaI enzyme. AS-PCR was applied on the nested-PCR product to know the genotypic and allelic frequency. Result: The nested PCR amplified product showed approximately 820 bp in all cases and PCR-RFLP revealed 462 bp, 211 bp and 147 bp fragments, which confirmed the species as H. Contortus. Frequency of resistant allele ('r') was 49.7% and 50.3% for susceptible allele ('S '). Frequency of homozygous resistant (rr), heterozygous susceptible (rS) and homozygous susceptible (SS) genotype were 33.83 per cent, 31.81 per cent and 34.34 per cent, respectively. The frequency of homozygous resistant (rr) genotype was low (19.61%) in field compare to farm (48.96%) indicating refugia in field region.
