Kerala Agricultural University, Thrissur

The history of agricultural education in Kerala can be traced back to the year 1896 when a scheme was evolved in the erstwhile Travancore State to train a few young men in scientific agriculture at the Demonstration Farm, Karamana, Thiruvananthapuram, presently, the Cropping Systems Research Centre under Kerala Agricultural University. Agriculture was introduced as an optional subject in the middle school classes in the State in 1922 when an Agricultural Middle School was started at Aluva, Ernakulam District. The popularity and usefulness of this school led to the starting of similar institutions at Kottarakkara and Konni in 1928 and 1931 respectively. Agriculture was later introduced as an optional subject for Intermediate Course in 1953. In 1955, the erstwhile Government of Travancore-Cochin started the Agricultural College and Research Institute at Vellayani, Thiruvananthapuram and the College of Veterinary and Animal Sciences at Mannuthy, Thrissur for imparting higher education in agricultural and veterinary sciences, respectively. These institutions were brought under the direct administrative control of the Department of Agriculture and the Department of Animal Husbandry, respectively. With the formation of Kerala State in 1956, these two colleges were affiliated to the University of Kerala. The post-graduate programmes leading to M.Sc. (Ag), M.V.Sc. and Ph.D. degrees were started in 1961, 1962 and 1965 respectively. On the recommendation of the Second National Education Commission (1964-66) headed by Dr. D.S. Kothari, the then Chairman of the University Grants Commission, one Agricultural University in each State was established. The State Agricultural Universities (SAUs) were established in India as an integral part of the National Agricultural Research System to give the much needed impetus to Agriculture Education and Research in the Country. As a result the Kerala Agricultural University (KAU) was established on 24th February 1971 by virtue of the Act 33 of 1971 and started functioning on 1st February 1972. The Kerala Agricultural University is the 15th in the series of the SAUs. In accordance with the provisions of KAU Act of 1971, the Agricultural College and Research Institute at Vellayani, and the College of Veterinary and Animal Sciences, Mannuthy, were brought under the Kerala Agricultural University. In addition, twenty one agricultural and animal husbandry research stations were also transferred to the KAU for taking up research and extension programmes on various crops, animals, birds, etc. During 2011, Kerala Agricultural University was trifurcated into Kerala Veterinary and Animal Sciences University (KVASU), Kerala University of Fisheries and Ocean Studies (KUFOS) and Kerala Agricultural University (KAU). Now the University has seven colleges (four Agriculture, one Agricultural Engineering, one Forestry, one Co-operation Banking & Management), six RARSs, seven KVKs, 15 Research Stations and 16 Research and Extension Units under the faculties of Agriculture, Agricultural Engineering and Forestry. In addition, one Academy on Climate Change Adaptation and one Institute of Agricultural Technology offering M.Sc. (Integrated) Climate Change Adaptation and Diploma in Agricultural Sciences respectively are also functioning in Kerala Agricultural University.

    Isolation and characterization of Chlamydia psittaci with emphasis on protein profile
    (Department of Microbiology, College of Veterinary and Animal Sciences, Mannuthy, 2001) Binu, K Mani; KAU; Mini, M
    For isolation of Chlamydia psittaci 46 clinical cases associated with abortions in livestock from livestock farms and Veterinary hospitals in and around Thrissur were screened. Impression smear staining of the clinical materials USin9 Giemsa, Modified Ziehl Neelsen and Gimenez revealed two positive cases. Both were from aborted foetuses, one from bovine (M-121) and the other from caprine (M-430). Chick embryo inoculation by YS route was used for isolation of the organism. The organisms could be isolated only from the two cases positive by preliminary screening, as confirmed by staining of YS impression smears. The mortality rate in CE was more in case of M-430 compared to the other two isolates (M-121 and reference isolate, P-156). All the three isolates produced patchy haemorrhagic lesions in YS and skin of embryoS. An overall isolation percentage of 4.3 was obtained in this study. All the three isolates were resistant to sodium sulphadiazine. Pathogenicity studies indicated that, all the three isolates were of moderate virulence for mice and guinea pigs. Based on AGPT, the local isolates were confirmed as Chlamydia psittaci. All the three isolates caused rounding and swelling of fibroblast cells and syncytia formation at 24h PI in Mc Coy cell line. By 48 to 72 h PI, these effects became more prominent with detachment of cells from adjacent cells and from the glass surface. Purified EBs were prepared from infected Mc Coy cell line by Urografin gradient centrifugation. After confirming the presence of sufficient amount of protein by Biuret method, they were used for SDS-PAGE. A total of 12 polypeptide bands were obtained for both the bovine isolates while the caprine isolate gave 10 bands. Molecular weights of 148 kDa and 135 kDa were present only in P-156 and 152 kDa and 137 kDa were unique for M-121. Bands at 152 kDa, 148 kDa, 137 kDa, 135 kDa, 32 kDa, 18 kDa, 15 kDa and 7 kDa were lacking in M-430. This isolate was having unique bands of 155 kDa, 19 kDa, 12.2 kDa and 6.4 kDa.
