Major Achievements


  • Diseases identified for the first time in the country: malignant catarrhal fever, infectious bovine rhinotracheitis/ infectious pustular vulvo-vaginitis, Mycoplasma agalactia in goats and M. bovigenitalium in cattle.
  • IFAT for Johne's disease and MIT for rabies used first time for diagnosis.
  • Modified Periodic Acid-Schiff reagent and turpentine oil as clearing agent was developed.
  • Ultra-structural alterations in Johne’s disease and bovine horn cancer were studied.
  • Diagnostic tests were developed: micro HI test for ND and EDS-76, and embryo susceptibility test for avian encephalomyelitis.


  • Classical swine fever: biological tests were conducted and the seed virus prepared.
  • Canine venereal sarcoma and sheep choroid plexus cells for Maedi-visna were successfully grown in tissue culture.
  • Goitre in 15 % goats in Bareilly area was identified.
  • MATSA test standardized for detection of Marek’s disease.
  • Vaccines developed: inactivated, oil-based tissue culture and/or embryo origin vaccines against ND, IBD, Reo, EDS-76, IBH and DVH; combined inactivated vaccines: ND, EDS-76 and IBD.
  • New pathogens detected for the first time: Reovirus from arthritis and stunted syndrome in 1986 and vvIBDV from IBD outbreak in poultry in 1988.
  • Diagnostic monitoring kits developed: COFAL kit for ALSV infection in 1986 and Dot-ELISA kit for RD vaccinal immunity in 1989.


  • Bacterial culture, AGID, ELISA, PCR, RE-analysis and DNA probes were developed for diagnosis and molecular identification of MAP (M. avium sub sp. paratuberculosis) infection.
  • Animal models (sheep & goat, rabbit and mouse) for paratuberculosis were developed.
  • Nucleic acids based diagnostic RT-PCR and TaqMan real time PCR were developed for CSFV diagnosis.
  • The prevalence of Enzootic Bovine Hematuria in Uttarakhand, levels of ptaquiloside and quercetin toxins in different ferns, and EBH pathology were determined.
  • Pathogens recovered for the first time: avian leucosis virus (ALV) subgroup “A” from bird suffering from osteopetrosis.
  • A new histochemical technique for the differentiation of quail heterophils and eosinophils in tissues developed.
  • Vaccines developed: thermo-stable IBD Indian strain vaccine, a highly proliferative vaccine strain of EDS-76 virus, live cell culture vaccines against MD, IBD, Reo, IB, ILT and Turkey pox.


  • Ochratoxin-A (OT-A), aflatoxin B1 (AT-B1), either alone or in combination were found to be quite common (0.05 to 3 ppm) in feeds/ ingredients in the country.
  • Experimental studies showed that AT- B1 induces hepatic cancer in rats. Both the toxins in rats and rabbits resulted into several gross, visceral and skeletal anomalies in fetuses/neonates.
  • Multiplex and real time PCRs developed for the diagnosis of MAP infection.
  • Indian MAP isolates were found to be “bison” type and PFGE type 25 by IS1311 gene PCR-REA and PFGE analyses.
  • Mechanism of cell death (apoptosis or necrosis) induced by MAP infection in bovine macrophages elucidated.
  • National Classical Swine Fever Referral Laboratory was established.
  • Biotinylated and DIG labeled DNA and RNA probes were developed and applied for CSFV detection by in situ hybridization.
  • PMWS caused by porcine circovirus-2 was reported for the first time in the country.

2010-till 2016

  • Mannan oligosaccharide and Ascorbic acid were found to ameliorate the toxic effect of OT-A up to 85-90%, suggesting their field application.
  • Indian isolates of CSFV belonged to genotypes 1.1 and 2.2 reported first time in the country.
  • Swine influenza disease was confirmed for the first time in the country and the virus revealed close homology to the human H1N1 pandemic (2009) virus.
  • Porcine circovirus-2 was isolated and its genetic characterization indicated prevalence of PCV2a and PCV2b and genetic recombinants of these genotypes.
  • BPV-1 & -2 identified in cutaneous and mucosal warts of cattle/buffaloes and yaks; sarcoids and squamous cell carcinomas in horses, mules and ponies; BPV-1, -2, -5 and -10 and their combinations in cattle and buffaloes by PCR.
  • Cancer biomarkers studied in canine tumours, urinary bladder cancers and experimentally induced tumours of rats.
  • PCR standardized for the diagnosis of IBD, IB, MD, IBH, EDS-76, CIAV, Reo virus, Duck plague, Fowl pox, Turkey pox, Quail pox and ND virus infections.
  • Multiplex PCR for simultaneous detection of MDV, ALV-A and REV developed and a LAMP test for MDV-1 oncogene meq developed.
  • JEV isolated from stillborn piglets with hydrocephalus and hydranencephaly first time and was sequenced.
  • Pathogenesis of Streptococcus suis was established in laboratory mice model.
  • Wildlife diseases reported since 1984: ICH (wolf and sloth bear), CD (tigers, lion and red panda), ND (peacocks), rabies (sloth bear, sambar deer and rhinoceros); leptospirosis (carnivores and herbivores), TB ( sloth bear, spotted deer and nilgai); Anaplocephala enteritis (rhinoceros), Dirofilaria immitis, Taenia pisiformis and Toxocara cati (tigers), Physaloptera (tiger and leopards), schistosomosis (dolphin), Aleurostrongylus (leopard cat), lung worms (leopard), Gossia/calyptospora protozoan (ghariyals), fasciolosis (black bucks); systemic aspergillosis (peacocks and Himalayan griffon vultures) etc.
