Aim: To know the gastrointestinal parasitic infections in cattle of Meghalaya, India. Materials and Methods: A total of 676 faecal samples of cattle were collected for a period of two years from different organized cattle farms of Meghalaya for detection of gastrointestinal parasitic infections, using standard techniques. Results: Out of 676 faecal samples examined, 191 (28.25%) faecal samples were found positive for gastrointestinal parasitic infections. The eggs of Strongyle spp. were found predominant (65.96 %) followed by Strongyloides spp. (25.13%), Eimeria spp. (17.80%), Trichuris spp. (13.08%), Moniezia spp. (10.47%) and Nematodirus spp.(2.61%). The Nematodirrus spp. was identified as Nematodirus helvetianus, a first report of its kind from cattle of North-Eastern Region of India, particularly from the state Meghalaya. The eggs per gram of faeces in case of nematode parasites were ranged between 50 to 4000 and in case of coccidian infections the range of oocysts per gram of faeces (OPG) was between 50 to 1400. Conclusion: Cattle maintained in organized cattle farms of Meghalaya suffers from GI parasitic infections throughout the year. It is highest during rainy season followed by cool, cold and hot season.

The objective of the study was to detect Babesia infections in pet dogs of a north-eastern state of India. The diagnostic efficacy of Babesia infection by polymerase chain reaction (PCR) technique has been compared with microscopy examination. For this, a total of 111 blood samples of pet dogs presented at clinical complex of the College of Veterinary Science, Guwahati, Assam with clinical signs suspected for Babesia infection subjected to the study. A total of 44 (39.63 %) dogs were diagnosed as positive for Babesia infections after microscopic examination. Among these, Babesia canis infection was diagnosed in 5 dogs (4.50 %) and B. gibsoni infection in 39 (35.13 %) dogs microscopically in Giemsa stained blood smears. Molecular diagnosis using PCR detected 63 (56.75 %) dogs positive for Babesia infection. Single infection with B. canis was found in 9 (8.10 %) dogs while B. gibsoni alone was detected in 3 (2.70 %) dogs. Mixed infections by both these species were detected in 51 (45.94 %) dogs. Overall, PCR detected 54 (48.64 %) dogs as B. gibsoni and 60 (54.05 %) dogs as B. canis positive.
Aim:The aim of this study was to determine the prevalence of gastrointestinal (GI) parasitic infections in goats of hilly region of Meghalaya.Materials and Methods:A total of 834 fecal samples of goats were screened for 1 year (2014-2015) using flotation techniques.Results:The overall prevalence of GI parasitic infections in goats was 28.65%. Season-wise highest infections were recorded during rainy season (34.92%) followed by cool (26.87%), hot (26.62%), and cold (20.39%) seasons. Helminths and protozoa infections were recorded in 63.60% and 23.02% animals, respectively. Among the helminths, Strongyle spp. (32.63%) was recorded highest followed by Trichuris spp. (12.55%), Moniezia spp. (10.04%), and Trichuris spp. (8.36%). Among protozoa, only Eimeria spp. was detected. Seven different species of Eimeria spp. were identified, viz., Eimeria christenseni, Eimeria hirci, Eimeria caprina, Eimeria jolchijevi, Eimeria ninakohlyakimovae, Eimeria arloingi, and Eimeria kocharii for the first time from Meghalaya. Maximum egg per gram and oocyst per gram of feces were recorded in the month of August (932.4) and September (674.05), respectively. Mixed infections were recorded in 13.38% samples. Coproculture of goat fecal samples revealed the presence of Haemonchus contortus (72.16%), Oesophagostomum spp. (14.41%), Strongyloides spp. (8.91%), and Trichostrongylus spp. (4.50%) larvae.Conclusion:This study indicates that GI helminths and protozoa infections are prevalent in goats of this hilly region of Meghalaya, throughout the year and highly prevalent during rainy season.
A total of 333 blood samples were collected from cattle suspected for haemoprotozoan infections from three states of north-eastern part of India. All the samples were examined for diagnosis of Babesia bigemina infection using PCR for detection of specific DNA. Out of these, 12 (3.60%) samples were found positive for B. bigemina DNA on PCR using the organism-specific primers derived from 18S ribosomal RNA (rRNA) gene of B. bigemina. An expected size of 1124-bp PCR product was visualized on agarose gel electrophoresis with all the 12 samples, and four of the products was further cloned and sequenced. Basic Local Alignment Search Tool (BLAST) analysis of B. bigemina sequences generated in the present study share 99.2 to 99.7% identity at 18S rRNA gene nucleotide sequence level. These Indian B. bigemina sequences were found to be closely related with the cognate gene nucleotide sequences of B. bigemina from Argentina and Kenya where 99.1 to 99.9% and 99.0 to 99.7% nucleotide identities were observed, respectively. Distant relationship of these Indian organisms was observed with few cognate gene sequences from China where more than 7% divergence was observed in the distance matrix.
