RESUMEN
A study was carried out to ascertain the status of ecto-parasites infesting dogs of Shimoga region. A total of 120 dogs with the history of skin problems presented to the local hospitals and local pet clinics of Shimoga region were screened for different ecto-parasites. The ticks, fleas and lice were collected, processed and identified. The skin scrapings were also collected from the affected dogs and processed for identification of mites. Out of 120 dogs examined, 59 (49.1 %) had harboured ecto-parasites. Among 59 infested pet dogs, 22 (37.28 %) positive for Fleas, 18 (30.5 %) for ticks, 09 (15.2 %) for Lice, 07 (11.8 %) for Sarcoptic mange and 03 (5.0 %) were for Demodectic mange conditions. The two species of fleas were identified as Ctenocephalides canis 13 (59 %) and Ctenocephalides felis 9 (41 %). The ticks and lice species were identified as Riphicephalus sanguineus and Trichodectus canis respectively. The mite species infecting dogs were identified as Sarcoptes scabeii and Demodex canis based on the morphological character. The Prevalence of ectoparasites was more in stray and adults dogs compared to pet dogs and puppies respectively.
RESUMEN
The study was conducted to ascertain the actual status of gastro-intestinal parasites in pigs maintained under different rearing systems in Shimoga region, Karnataka state. A total of 150 Pigs fecal samples were examined, which includes 50 from organized piggery farm, Veterinary College Shimoga, 50 from private piggery farm of Shimoga and 50 from free range desi pigs of Shimoga city. The fecal samples were processed and examined by direct and sedimentation method. Out of 50 fecal samples examined from organized piggery farm, 19 were found positive for different parasitic eggs, Out of 50 fecal samples screened form private farm, 28 harbored different parasites, whereas from 50 free range desi pigs fecal samples examined, all showed one and other parasitic eggs/ova. The percent prevalence of parasitic infection is more in free range desi pigs compared to Yorkshire breeds maintained under stall fed condition.
RESUMEN
A study was conducted to record the prevalence of Haemoprotozoan infections in bovines of Shimoga region for a period of 1 year from April 2012 to March 2013. A total of 300 blood samples were examined for the presence of haemoprotozoan parasites, of which 215 from cattle and 85 from buffaloes were examined by Giemsa staining technique. Out of 300 blood samples examined, 130 (43.3 %) were found positive for Haemoprotozoan infections. Out of 215 cattle blood samples examined, 62 (28.8 %) were positive for Theileria annulata, 27 (12.5 %) were harbored Babesia bigemina, 15 (6.9 %) were found positive for Trypanosoma evansi and 06 (2.7 %) samples showed Anaplasma marginale. Among 85 buffalo samples examined, 11 (12.9 %) were showed Theileria spp, 04 (4.7 %) found positive for B. bigemina, 03 (3.5 %) were found positive for T. evansi and 02 (2.3 %) were positive for A. marginale. Among haemoprotozoan parasites, the highest prevalence was observed with T. annulata followed by B. bigemina and T. evansi infection. The lowest prevalence was observed with A. marginale infection.
RESUMEN
A study was conducted to ascertain the incidence of gastrointestinal parasites in horses of Shimoga region, to generate the data regarding status of parasitic infections of equines in Karnataka state due to paucity of information. A total of 100 fresh fecal samples of equines were collected and examined by direct and sedimentation method for the detection of parasitic egg/ova. Among 100 samples examined, 84 (84.0 %) were found positive for various gastrointestinal helminths. Out of 84 positive cases, 44 (52.38 %) were found positive for Strongylus spp. eggs, 09 (10.71 %) showed Parascaris equorum eggs, 06 (7.14 %) had Gastrodiscus spp. eggs, 04 (4.76 %) harbored Oxyuris equi and the remaining 21 (25.0 %) had a mixed infection of Strongylus spp., Strongyloides spp. and Gastrodiscus spp.
RESUMEN
Fasciola gigantica, causative agent of tropical fasciolosis, inflicts substantial economic losses on the livestock industry, affecting severely buffalo productivity in the tropical countries. Very few vaccination trials with different target antigens against F. gigantica infection have been conducted in this host. Present study describes a vaccination trial in buffaloes with F. gigantica recombinant glutathione S-transferase and fatty acid binding protein. The two recombinant proteins were expressed in Escherichia coli and evaluated for their immunoprophylactic potential in buffalo calves, using montanide 70 M-VG, a mineral oil-based adjuvant, for delivering the antigens. Buffalo calves were distributed in three groups, with group I, II and III calves immunized with recombinant glutathione S-transferase, fatty acid binding protein and a cocktail of these two antigens, respectively. Immunization of the calves evoked a mixed IgG1 and IgG2 antibody response. Present vaccination trial in these animals achieved a maximum protection level of 35%, when the two antigens were used in combination. Eosinophils were measured in both immunized and non-immunized challenge control animals, which showed a steady increase in their count in response to immunization with both the antigens and infection with F. gigantica, respectively.
