Control of poultry coccidiosis: changing trends.
A. K. Tewari,B.R. Maharana +1 more
TL;DR: Although in the near future more varieties of oocyst based live vaccines are expected, identification of selective coccidian-specific immunoprotective molecules is likely to get more attention to facilitate the sustainable control of poultry coccidiosis.
Journal ArticleDOI

TL;DR: In this paper, the authors provided the broadest map yet of Eimeria occurrence for domestic chickens, confirming that all the known species (Eimeria acervulina, EIMeria brunetti, eimeria maxima, Eimereria mitis, eimereria necatrix, eimmeria tenella) are present in all six continents where chickens are found and highlighted a trend towards widespread genetic variance.
Journal ArticleDOI
Prevalence and molecular characterization of bovine Cryptosporidium isolates in India
Souvik Paul,D. Chandra,D. D. Ray,A. K. Tewari,J. R. Rao,P.S. Banerjee,Surajit Baidya,O.K. Raina +7 more
TL;DR: Results indicated that C. parvum was the only species of Cryptosporidium prevalent in bovine calves in three different geographical regions of India, and highest prevalence was recorded in the monsoon months.
Journal ArticleDOI
High-level expression of SAG1 and GRA7 gene of Toxoplasma gondii (Izatnagar isolate) and their application in serodiagnosis of goat toxoplasmosis
TL;DR: The reactivity of the recombinant proteins as a cocktail preparation was more than that of individual proteins in ELISA and could detect accurately the infection in goats.
Journal Article
Haemoprotozoa of cattle in Northern Kerala, India.
A. S. Nair,Reghu Ravindran,Bindu Lakshmanan,Swaroop S. Kumar,P. V. Tresamol,M. R. Saseendranath,K. Senthilvel,J. R. Rao,A. K. Tewari,Srikant Ghosh +9 more
TL;DR: The higher prevalence rate of Trypanosoma evansi indicated that the subclinical parasitism can be due to higher prevalence of tabanid flies, and the presence of a theilerial piroplasm other than T. annulata in North Kerala needs further investigation.
