Professional experience:

Owing to immense public health concerns and economic impact of brucellosis to ruminant livestock, the work was initiated in my laboratory way back in late eighties. Initially when I started working on this nationally important problem the information was scanty in India. I had several successful isolations of Brucella abortus organisms in my lab and established internationally recognized laboratory protocols for isolation and characterization of this very important zoonotic pathogen. Though quite a few conventional antigen-antibody based assays were available, a need was felt to have more sensitive, specific, rapid and reliable diagnostic assay which could be used for detection of Brucella in a variety of clinical specimens. In an effort to develop on spot assay, a collaborative research was established with National Institute of Immunology under the guidance of Professor G.P. Talwar. This collaboration resulted into development of a very useful spot test. Based on my substantive contribution from India as evidenced by quality international publications I was invited as an Indian expert in the meeting jointly organized by FAO/WHO in China in 1992. My laboratory continued to expand work on different dimensions of brucellosis under which a study was conducted to assess the impact of brucellosis in breeding rams. For the first time we could isolate Brucella melitensis from clinical cases of breeding rams. Subsequently an excellent diagnostic assay for detecting Brucella antibodies in sheep milk by ELISA was developed. Thus having gained considerable experience and insight into Brucella disease complexity, we were in a position to develop a model for control of brucellosis at farm level. The idea of this control model was proposed to an organized government farm which gained acceptance at the highest level of National policy making body. Based on laboratory’s scientific advice, the said farm adopted the policy of vaccination in sheep against this dreaded disease. Due to success obtained in this organized farm having around 7000 animals, I have been an experienced expert in several policy making bodies of the State and Central Governments. Considering long experience in the field I was invited to develop a national training for Continuing Veterinary Education Program of Government of India under aegis of Veterinary Council of India. More recently, on the advice and strong recommendations from my laboratory the Animal Husbandry Commissioner, Govt. of India convened an Experts Consultation Meeting in which the existing brucellosis control program for bovines was revised and it was resolved and decided to include adult animal vaccination, besides calf-hood vaccination. On my recommendations, reduced dose of S19 vaccine by conjunctival route of inoculation was accepted to vaccinate adult animals.
