Assam Agricultural University, Jorhat

Assam Agricultural University is the first institution of its kind in the whole of North-Eastern Region of India. The main goal of this institution is to produce globally competitive human resources in farm sectorand to carry out research in both conventional and frontier areas for production optimization as well as to disseminate the generated technologies as public good for benefitting the food growers/produces and traders involved in the sector while emphasizing on sustainability, equity and overall food security at household level. Genesis of AAU - The embryo of the agricultural research in the state of Assam was formed as early as 1897 with the establishment of the Upper Shillong Experimental Farm (now in Meghalaya) just after about a decade of creation of the agricultural department in 1882. However, the seeds of agricultural research in today’s Assam were sown in the dawn of the twentieth century with the establishment of two Rice Experimental Stations, one at Karimganj in Barak valley in 1913 and the other at Titabor in Brahmaputra valley in 1923. Subsequent to these research stations, a number of research stations were established to conduct research on important crops, more specifically, jute, pulses, oilseeds etc. The Assam Agricultural University was established on April 1, 1969 under The Assam Agricultural University Act, 1968’ with the mandate of imparting farm education, conduct research in agriculture and allied sciences and to effectively disseminate technologies so generated. Before establishment of the University, there were altogether 17 research schemes/projects in the state under the Department of Agriculture. By July 1973, all the research projects and 10 experimental farms were transferred by the Government of Assam to the AAU which already inherited the College of Agriculture and its farm at Barbheta, Jorhat and College of Veterinary Sciences at Khanapara, Guwahati. Subsequently, College of Community Science at Jorhat (1969), College of Fisheries at Raha (1988), Biswanath College of Agriculture at Biswanath Chariali (1988) and Lakhimpur College of Veterinary Science at Joyhing, North Lakhimpur (1988) were established. Presently, the University has three more colleges under its jurisdiction, viz., Sarat Chandra Singha College of Agriculture, Chapar, College of Horticulture, Nalbari & College of Sericulture, Titabar. Similarly, few more regional research stations at Shillongani, Diphu, Gossaigaon, Lakhimpur; and commodity research stations at Kahikuchi, Buralikson, Tinsukia, Kharua, Burnihat and Mandira were added to generate location and crop specific agricultural production packages.

    PREVALENCE OF BRUCELLOSIS IN ANIMALS AND MAN USING CONVENTIONAL AND MOLECULAR TECHNIQUES
    (College of Veterinary Science Assam Agricultural University Khanapara, Guwahati-781022, 2016-07) GOGOI, SAMIR BIKASH; Hussain, P.
    Brucellosis is an infectious, economically ravaging reproductive disease of animal and one of the re-emerging major zoonoses with world-wide distribution. The present work was conducted (i) to screen the animals and human being of different age groups against brucellosis and (ii) to compare the different tests used for diagnosis of the disease. The study was conducted from February, 2015 to May, 2016. A total of 174 milk samples (152 milk sample from cattle and 22 from goat) and 773 serum samples (520, 138 and 115 serum samples from cattle, goat and pig respectively) were collected randomly from animals having history of clinical symptoms suspected to brucellosis as well as from apparently healthy animals of different age groups, from different districts of Assam were screened by MRT, RBPT, STAT and I-ELISA tests. The prevalence of brucellosis was recorded, 10.53%, 12.69%, 13.08% and 13.84% in cattle by MRT, RBPT, STAT and I-ELISA respectively and 1.45% prevalence rate was recorded in goat by all the three serological tests. All the serum samples from pig found negative by serological tests. Sex-wise higher prevalence rate was recorded in female cattle (14.06%), Age-wise highest prevalence recorded in the age group of 3-7 year (15.09%), breed-wise higher prevalence in crossbred cattle (20.00%) and cattle from organized farm recorded higher prevalence (15.65%) than unorganized farm by I-ELISA. In case of goat, sex-wise prevalence rate was recorded in female was 2.15%, age-wise in the age group of 9-18 months of age was 4.76%, breed-wise prevalence found in indigenous breed of goat was 1.56% and prevalence rate recorded from unorganized farm was 1.82% by I-ELISA. Prevalence rate on the basis of previous history or clinical symptoms recorded highest in case of aborted cattle (64.24%) followed by retention of placenta (47.13%) in cattle. In case of goat, prevalence rate recorded only in aborted goat by I-ELISA was 16.67%. The comparative efficacy of the different tests showed that maximum positive reactors was detected by I-ELISA (13.85%) followed by STAT (13.08%), RBPT (12.69%) and MRT (10.53%). All the serum samples collected from human were showed negative by RBPT and STAT. Brucella organism has been demonstrated in clinical samples of vaginal swab, uterine discharge and placenta by modified Ziehl Neelsen Stain. In genus specific PCR, out of 47 clinical samples 6 showed amplification of Brucella bacterial nucleic acid, at 223bp for BCSP31 gene using gene specific primers.
