Putative SNPs in Ovar-DRB1 and GALNTL6 Genes Conferring Susceptibility to Natural Infection of Haemonchus Contortus in Southern Indian Sheep.

Aim: To explore associations between phenotypic traits and polymorphisms in the DRB1 and GALNT6 gene in Nellore, Deccani and Kenguri sheep naturally infected with Haemonchus contortus.

Materials And Methods: Blood and faecal samples were collected to evaluate fecal worm egg counts (FEC), packed cell volume (PCV), hemoglobin (Hb), eosinophilia and for DNA isolation.

Results: Animals were grouped into susceptible and resistant groups based on EPG counts.

Assessment of Mutation Drift Equilibrium and the Occurrence of a Recent Genetic Bottleneck in South Indian Zebu Cattle.

During the last few decades, the effective population size of indigenous zebu cattle breeds has declined drastically, resulting in the classification of some of them into the vulnerable, endangered, or critically endangered category. Drastic reductions in the effective size of a population may result in genetic bottlenecks and can affect within-breed genetic variability and its viability. The present study was undertaken with the objective of evaluating South Indian zebu cattle populations for mutation drift equilibrium and to detect the occurrence of recent genetic bottleneck events.

Single nucleotide polymorphism in STAT5A could not endorse variation in milk production traits in Indian bovine population.

The Signal Transducer and Activator of Transcription 5A (STAT5A) gene involved in activating the transcription of milk protein genes was predicted to be influencing milk production traits. The present study was undertaken to investigate the suitability of the polymorphism of STAT5A as a marker for milk traits in Ongole, crossbred cattle and Murrah buffaloes from Southern India. Blood samples (n = 502) for DNA isolation and milk samples (n = 222) from different genetic groups were collected from various farms.

Cypermethrin and ivermectin resistance in field populations of Rhipicephalus sanguineus sensu lato (Latrielle, 1806) collected from dogs in south India.

The abuse of acaricides for control of Rhipicephalus sanguineus sensu lato ticks led to a strong selection pressure for acaricide resistance. Data on acaricide resistance in R. sanguineus s.

Legacy of draught cattle breeds of South India: Insights into population structure, genetic admixture and maternal origin.

The present study is the first comprehensive report on diversity, population structure, genetic admixture and mitochondrial DNA variation in South Indian draught type zebu cattle. The diversity of South Indian cattle was moderately high. A significantly strong negative correlation coefficient of -0.

Evaluation of non-synonym mutation in DGAT1 K232A as a marker for milk production traits in Ongole cattle and Murrah buffalo from Southern India.

Various candidate genes have been reported to affect milk yield and composition in dairy cattle. A non-synonymous mutation in the DGAT1 gene, i.e.

In Vitro Anthelmintic Activity of Three Tropical Plant Extracts on Haemonchus contortus.

Aim: To evaluate the anthelmintic activity of Anacardium occidentale shell, Illicium verum fruit, and Artocarpus heterophyllus seed to substantiate their traditional use against helminths.

Materials And Methods: In vitro anthelmintic activity of hydroalcoholic extracts of three plants was evaluated against eggs, infective larvae (L3), adult, and lactate dehydrogenase (LDH) of Haemonchus contortus of naturally infected sheep.

Results: The three extracts exhibited significant (P < 0.

Studies on prevalence and histomorphology of species infecting cattle in Andhra Pradesh, India.

The present study was carried out to determine the prevalence of bovine sarcocystosis and identify the different species of cysts in cattle in different regions of Chittoor district, Andhra Pradesh. A total of 150 slaughtered cattle over a period of 1 year were examined both macroscopically and microscopically for the presence of infection. Out of 150 slaughtered cattle examined, macroscopic sarcocysts were observed in nine cattle and were exclusively found in oesophagus.

PCR test for detecting Taenia solium cysticercosis in pig carcasses.

Polymerase chain reaction (PCR) test was employed to detect Taenia solium DNA in muscle lesions for validation of the meat inspection results of slaughtered pigs. Two sets of oligonucleotide primers, one targeted against the large subunit rRNA gene (TBR primers) and the other targeted against cytochrome c oxidase subunit 1 gene (Cox1 primers) of T. solium were used in this study.
