During the course of infection of calves with Theileria annulata levels of glucose, calcium, proteins, phosphorus, magnesium and potassium decreased and those of bilirubin, cholesterol and alkaline phosphatase increased with no changes in sodium and acid phosphatase levels. Several of these biochemical alterations have been explained in relation to the(More)
Epidemiological studies on some gastrointestinal nematodes of sheep and goats in Karnal, Ambala and Rohtak districts of Haryana (India) revealed that Haemonchus contortus and Trichostrongylus spp. were responsible for parasitic gastroenteritis in these hosts. The adult parasites persisted in the host throughout the year and there was no indication of(More)
A survey was undertaken between March and September 1992 to assess the prevalence of fenbendazole resistance in sheep nematodes in 32 traditionally managed rural flocks and 22 intensively managed flocks on 3 farms. Fenbendazole, a commonly used anthelmintic was used at the recommended dose of 5 mg/kg body weight. Efficacy was determined on the basis of(More)
Immune responses against Bm95 recombinant cattle tick antigen and its protective efficacy for control of Rhipicephalus (Boophilus) microplus ticks were determined in experimental crossbred cow calves. Anti-Bm95 antibody titers, as assessed by indirect ELISA, in immunized calves ranged from 196.1+/-13.7 on day 0 to 7979.9+/-312.5 on day 110 post-primary(More)
Rhipicephalus (Boophilus) microplus is an economically important ectoparasite of cattle. Chemical acaricides remain the most practical method for control of these pests. During past two decades there have been increasing reports of resistance development against synthetic pyrethroids in tick populations of this species throughout the world. A study was(More)
Ovine strains of Ostertagia and Trichostron~lus showing multiple resistance to anthelmintics were first reported in Australia (Sangster et al., 1979). In a recent report from South Africa, Haemonchus contortus has been reported to have developed resistance to a number of anthelmintics, including ivermectin (Van Wyk and Malan, 1988). Strains of H. contortus(More)
An allele-specific PCR was standardized to diagnose the mutation (Phe to Try) at residue 200 of the isotype 1 beta tubulin gene responsible for benzimidazole resistance in Haemonchus contortus adult and infective larvae. Adult and infective larvae of Haemonchus contortus were collected from sheep under different managemental practices (intensive and(More)
Epidemiological studies were conducted on Fasciola giagntica infection in different geo-climatic zones (hills, tarai and plains) in six states of north India during January 2001 to December 2004. Prevalence rates of 10.79, 13.90, 2.78 and 2.35 percent were recorded in cattle, buffaloes, sheep and goats, respectively. Animals in the tarai had the highest(More)
