Research:


Environmental Hygiene

  • The pond and canal waters were found to de highly polluted.
  • Study revealed that slaughter house environment was responsible for carcass containation.
  • Survey conducted in and around pantnagar revealed extensive use of pesticides such as chlorpyrifos, endosulphan, deltamethrin, lindane and monocrotofos by farmers.
  • Pesticide (chlorpyrifos & endosulphan) residues were found in varying concentrations in milk, meat, feed/fodder, fish and egg samples.
  • Residues of tetracycline were found in foods of animal origin.

  • Colibacillosis

  • Calf origin enterotoxin is of heat-stable (ST) type.
  • ST-type toxin partially characterized.

  • Food Hygiene

  • Milk culture filtrate obtained from Lactobacillus acidopillus strains exhibited antibacterial activity against various enteric as well as non-enteric organisms.
  • On the basis of SPC, 37.72% samples of milk, and 73.33% of cream collected form Pantanagar was found to be poor quality.84% of barfi samples were evaluated as unsatisfactory.
  • Enterobacteria isolated from meat, milk and its products showed high drug resistance and persistence of R-factor.
  • For differentiation of meat of various species of animals serological and electophoretic techniques were compared, disc electrophoretic method was found better.

  • Salmonellosis

  • Enterotoxins/cytotoxins produced by Salmonellae have been partially characterized.
  • Cytotoxic activity on cell monolayer has been demonstrated.
  • Mechanism of Salmonella enterotoxigenicity varies markedly forms that of E.coli. infection. It disrupts intestinal architecture.
  • Agar overlay technique found suitable for Salmonella toxin study.
  • DNA based molecular technique for detection of salmonella has been standardized.

  • Yersiniosis

  • Yesinia enterocolitica is serology important in the epidemiology of yersiniosis.
  • Screening for virulence needs to be carried with the help of multiple tests.
  • Enterotoxin (ST-type) of Yersinia enterocolitica was partially characterized.

  • Brucellosis

  • Prevalence showed increasing trends towards the last 3 decades.
  • Organize farms were found to be more affected than rural areas.
  • Rose Bengal Test and ELISA found efficient for screening of serum samples.
  • Female animals showed higher prevalence.
  • Brucella cell membrane proteins are being exploited for vaccine development.
