Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Evaluation of antibacterial activity of essential oils against bacterial flora of the field rodents in Hisar
    (CCSHAU, 2018) Ajay; Ravikant
    Studies on population dynamics of rodents was carried out in Seed science technology research farm area in Rabi and Kharif seasons and the field rodents were trapped during the investigation for bacterial isolation. This study was revealed that population dynamics of Rattus rattus was more as compare to, and Tetara indica in both seasons. Trap index was found highest in the second week and least in the first week of the sowing season but highest in the first week during harvesting season. Total nine bacteria were isolates from the field rodent i.e. M. musculus, T. indica and R. ratuus. On the basis of secondary biochemical tests, Salmonella, Klebsiella, Eschierichia, Citrobacter, Staphylococcus and Proteus were more prevalent in captured rodent species. To determine the antimicrobial resistance occurs in various bacterial agents isolated from rodents. The bacterial isolates were analyzed for antimicrobial susceptibility to fourteen antibiotics and four essential oils at different concentrations. The bacterial isoletes no. RRA2, TIA1 and TIA2 were found multidrug resistance towards three antibiotics (Ampicillin, Ampicillin/sulbactum, and Cefuroxime/Cephalothin) and have a great concern of matter to human and veterinary health. Thus rodents may be proving their role in spreading zoonotic diseases. The selected essential oils (i.e. Eucalyptus, lemon grass, clove and cinnamon) exhibited good antibacterial activity against all the tested bacterial isolates. Use of essential oils instead of antibiotics can help in diseases control.
