Rapid flow-through diagnostic kit for filariasis detection

Filariasis as a chronic health problem of our country in which neither the pharmaceutical industry nor the developed countries are interested. Sustained research on the molecular pathogenesis and genomics on this important disease, which affects millions in our country, has led to the development of a two-minute detection kit, which is being commercialized by Ms. Span diagnostics, Surat. This was achieved with years of international and national collaborations like Indo-US PL480 programme and industrial collaborations in which Ph.D. students were trained in advanced techniques and international quality work was published in reputed scientific journals as mentioned below.

Since early diagnosis and vaccination are the successful national programmes to fight infectious diseases as a partner of WHO-sponsored filarial genome project involving 6 countries the entire genome of the filarial parasite has been sequenced and 15 molecules of diagnostic and prophylactic importance were identified. These contributions have been duly recognized by WHO and enabled to receive an invitation from WHO, as an expert to discuss on the development of a diagnostic tests for filariasis in the meeting at Denver, USA in Nov 2002 and selected our diagnostic kit for multi-centre evaluation for global screening and received excellent comments from WHO. The product has been commercialized after Hon’ble Minister of Science and Technology and Earth Sciences, Dr. Kapil Sibal, launched the product on DBT Founder’s Day in April 2007. Now the product has been licensed by Drug Controller of State of Gujarat, Several lakhs of this kit has been sold in Indian and African markets in short time.

Owing to the success of this approach of translating basic scientific knowledge into technological products useful to society and its effectiveness in combating infectious diseases, DBT has granted Rs. 4.5 crores in programme support under Centre for Excellence in Biotechnology to develop platform for Diagnostic products and efficacious vaccines.
