OtherItem Open Access Amplification by PCR and Comparison of Hepatopancreatic Parvo Virus (HPV) of Shrimp from India and other Countries(TANUVAS, 2006-06) Uma, A; Ramanathan, N; Reddy, Y. Krishnamohan; Saravanabava, K; Singaravel, R; Koteeswaran, AArticleItem Open Access Assessment of Humoral Immune Response to IBDV Commercial Vaccines in Field Conditions(Indian Veterinary Association, 2015-01) Padmaja, J.; Saravanan, S.; Reddy, Y. Krishnamohan; TANUVASA comprehensive study which included differ- ent strains of commercially available infectious bursal disease virus vaccines administered in various regimens at field level. Quantification of hurnoral immune responses by ELISA and QAGID showed the onset of antibody responses in majority (80 per cent) of the birds by 7“‘ day. Studies till 84 day post vaccination suggest the use of either a single dose of intermediate plus vaccine strain or two doses of intermediate vaccine strain for enhanced protection in disease endemic regions with circulating maternal derived antibodies.ArticleItem Open Access Bluetongue Diagnosis and Control(TANUVAS, Chennai, 2011-12) Reddy, Y. Krishnamohan; TANUVASArticleItem Open Access Bluetongue in Migratory Sheep Population(Indian Journal of Small Ruminants, 2005) Balakrishnan, G.; Reddy, Y. Krishnamohan; Saravanabava, K.; Babu, M.; Koteeswaran, A.; TANUVASBluetongue is one of the 15 diseases of OIE list 'A' affecting susceptible domestic and wild ruminants caused by Orbi virus transmitted by Culicoides. The economic losses are mainly attributed to high morbidity, mortality, abortions, stillbirths, foetal abnormalities and loss of milk, meat and fleece. Moreover the presence of this disease in a country puts trade barrier on movement of ruminant animals, their germ plasm and other animal products resulting in animal related international trade losses. The disease prevalence has been reported world wide and widespread in India (Sapre, 1964; Mehrotra, 1991; Janakiraman et al., 1991). In Tamil Nadu, it was first reported in Dindigul region in the year 1982 followed by sporadic incidence in the Southern districts during 1987. This study describes a disease investigation carried out in migratory sheep population suspected for bluetongue in Pudukkottai district of Tamil Nadu during the month of November 2004.OtherItem Open Access Bluetongue in Ruminants and its Control by Vaccination(TANUVAS, Chennai, 2011-12) Reddy, Y. Krishnamohan; Manohar, B. Murali; Purushothaman, V.ArticleItem Open Access Bluetongue in Small Ruminants(TANUVAS, Chennai, 2013) Reddy, Y. Krishnamohan; TANUVASBluetongue is economicaliy important and is considered to be of such major international concern that it has been given Office International des Epizootics list ‘A' status. The acute economic losses due to BTV infections are mainly attributed to high morbidity, mortality, abortions, stillbirths, foetal abnornamalities milk, meat and fleece loss.ArticleItem Open Access Bursal Lesion Scoring For the Assessment of Severity of Infectious Bursal Disease(TANUVAS, Chennai, 2008-01) Reddy, Y. Krishnamohan; Manohar, B. Murali; Koteeswaran, A.; TANUVASInfectious bursal disease (IBD) is an acute infectious viral disease of chicken, which causes necrosis and atrophy of the bursa of Fabricius (BF) .Out of the two serotypes of IBDV, serotype1 is established as a pathogen to chickens.OtherItem Open Access Comparison of Infectious Bursal Disease Virus Isolates from Tamil Nadu(TANUVAS, Chennai, 2007-08) Reddy, Y. Krishnamohan; Saravanabava, K.; Thyagarajan, D.; Manohar, B. MuraliArticleItem Open Access Comparison of the Efficacy of Different Inactivated Infectious Hydropericardium Vaccines(2004-09) Reddy, Y. Krishnamohan; Ravikumar, G.; Manoharan, S.; Koteeswaran, A.; TANUVASArticleItem Open Access Congenital Aplasia of Left Kidney in a White Leghorn Chicken(Indian Vet. J., 1993-09) Dorairajan, N.; Balachandran, C.; Reddy, Y. Krishnamohan; TANUVASCongenital anomalies in domestic fowl have been reported earlier and most of them were case reports (Damodaran and Tanikachalam, 1974; Grewal et al., 1976, 1977; Peckham, 1984). The present paper reports a casd of aplasia of left kidney encountered in a ten - week old Babcock layer chicken among 24,725 cases of post-mortem (PM) attended at Poultry Research and Development Centre, Namakkal during 1980-90. On post-mortem examination the left kidney and the corresponding ureter were absent and the right kidney showed compensatory hypertrophy (Fig).ArticleItem Open Access Detection of Peste Des Petits Ruminants Virus Antibodies in Sera of Cattle(TANUVAS, Chennai, 2018-07) Giridharan, P.; Reddy, Y. Krishnamohan; TANUVASA total of 120 serum samples of cattle collected from six districts in Tamil Nadu were screened for PPRV antibodies. Competitive enzyme linked immune sorbent assay and micro serum neutralization test were used for seromonitoring of PPRV antibodies. In areas with no previous history of PPR incidence and PPRV vaccination in goats and sheep under field/ farmers holdings, the serum samples collected from selected cattle herds showed 8.3% positivity for PPRV antibodies by both cELISA and micro SNT, whereas in areas with previous history of PPR incidence and PPRV vaccination in goats and sheep, the cattle herds showed 18.3% positivity.ArticleItem Open Access DETECTION OF PESTE DES PETITS RUMINANTS VIRUS ANTIBODIES IN SERA OF CATTLE(TANUVAS, Chennai, 2018-07) Giridharan, P.; Reddy, Y. Krishnamohan; TANUVASA total of 120 serum samples of cattle collected from six districts in Tamil Nadu were screened for PPRV antibodies. Competitive enzyme linked immune sorbent assay and micro serum neutralization test were used for seromonitoring of PPRV antibodies.ArticleItem Open Access DETECTION OF SINGLE NUCLEOTIDE POLYMORPHISM OF A1/A2 VARIANTS OF BETA CASEIN GENE IN UMBALACHERY CATTLE BY TETRA ARMS PCR(TANUVAS, Chennai, 2018-05) Nila, R. Kalai; Brindha, K.; Reddy, Y. Krishnamohan; Baskaran, D.; TANUVASAll over the world, people fulfill 13% of their protein requirements through milk and milk products (Cifelli et al., 2015). Bovine milk contains two major protein groups namely caseins and whey proteins (Bell et al., 2006).ArticleItem Open Access Development of Bluetongue Vaccine for Sheep(TANUVAS, Chennai, 2012-09) Reddy, Y.

Krishnamohan; TANUVASMultiplex reverse transcriptase polymerase chain reaction (mRTPCR) was standardized by designing the primers for the amplification of VP5 gene of bluetongue virus (BTV) serotypes 1,2,10,16 and 23 by using primer-BLAST software of NCBI. mRT-PCR can be routinely used for the rapid determination of BTV serotype from clinical specimens from BT suspected sheep if 4 or 5 BTV serotypes are in circulation in a geographical area . Sequencing of mRT-PCR product is also useful in molecular epidemiological studies.ThesisItem Open Access DEVELOPMENT OF SPRAY DRIED MILK POWDER E USING MILK FROM A2 GENOTYPED NATIVE CATTLE(TANUVAS, Chennai, 2017) Kalainila, R.; Brindha, K.; Reddy, Y. Krishnamohan; Gnanalakshmi, K.S.; TANUVASThe present research work was carried with the objective of identifying A1 and A2 variants of beta casein gene in umbalachery breed and to develop spray dried milk powder from A2 milk.
