RÉSUMÉ

The field experiment was carried out during 2018-19 at AICRP on Integrated Farming Systems, Regional Sugarcane and Rice Research Station, Rudrur in vertisols of Northern Telangana Zone, Telangana state, India. The experiment was performed with twelve cropping systems as treatments in Randomized Block Design (RBD) with three replications. The twelve combinations of cropping systems tested during kharif (June-October) and rabi (November – March) were rice-rice (check), maize-soybean(2:4)-tomato, maize-soybean (2:4) - rice, sunflower-chickpea (2:4), maize - chickpea, Bt cotton-soybean (1:2) on broadbed–sesame-groundnut(2:4), Bt cotton - sesame -blackgram (2:4), soybean-wheat, soybean-sunflower -chickpea (2:4), turmeric-sesame, turmeric-soybean (1:2) on flat bed-bajra and turmeric-soybean (1:2) on broadbed-sesame - blackgram (2:4).Cropping system turmeric-soybean(1:2 ) (on BBF) sesame – blackgram (2:4) recorded productivity in terms of rice equivalent yield of 23413kg ha-1 and production efficiency of 75.53Kg ha-1 day-1followed by sole turmeric-sesame (22597 kg REY ha-1 ) and 72.89Kg ha-1 day-1 and Bt.cotton+soybean (1:2) (on BBF) sesame+groundnut (2:4) (22568kg ha-1) and 75.23 Kg ha-1 day-1 over existing rice-rice (14395 kg REY ha-1 ) and 56.45Kg ha-1 day-1. Higher nutrient uptake was recorded with maize+soybean (2:4)–tomato system with 361.73 kg N ha-1, 114.43 kg P ha-1 and 318.89 kg K ha-1. Hence under nutrient stressed environment and low input management system maize+soybean (2:4) –tomato, can be recommended in comparision to existing rice-rice cropping system in irrigated situations for vertisols of Telangana.

RÉSUMÉ

Aims: The aim of this study was popularize the developed high yielding, dual purpose, potential sorghum variety and its acceptability by the farming community.Study of Design: Randomized Block Design.Place and Duration of Study: The Present study was conducted at Regional Agricultural Research Station, Palem, Nagarkurnool and evaluated across fifteen AICRP centers at national level from 2010 to 2019.Methodology: A high yielding, dual purpose sorghum variety was derived from a cross between SPV-86 x ICSR-89064 through Pedigree method of breeding and subsequently it was evaluated at station level from 2013 – 2015 and also at AICRP system from fifteen centers during 2016 – 2018 for its grain and fodder yield and resistance to pests and diseases and showed superior performance over the three nation checks.Results: Sorghum culture SPV 2437 recorded highest grain and fodder yield of 3179.8 kg ha-1 and15900.2 kg ha-1and yielded +39.25%, +3.86% and +14.88% higher grain yield and +92.48, +13.59, and +8.46 higher fodder yield superiority than checks CSV 17, CSV 20 and CSV-27 and shown 3.67 mean field grade and 4.37 mean threshed grade showing resistant reaction to grain mold disease.Conclusion: The sorghum variety SPV 2437 with higher grain and fodder yield, resistance to pest and disease and good cooking quality as compared to the check varieties was released through central varietal release committee during 2020 for Zone I (Andhra Pradesh, Telangana, Tamil Nadu, Rajasthan and Gujarat states) on the name of Telangana Jonna 1/CSV 41 and gaining its importance across the states for its high potential yield.

RÉSUMÉ

During 1992-96, outbreaks of buffalopox zoonosis were reported from different villages in Jalgaon, Dhule and Beed districts of Maharashtra State. In humans, pox lesions were observed on the hands whereas in affected buffaloes and cows the lesions were noticed mainly on the teats and udder. Twenty two virus strains were isolated from the skin scabs collected from infected humans and milch animals. Neutralizing antibodies were detected not only in the sera of affected humans but also in their contacts. Detection of antibodies in young individuals from endemic area, who were neither vaccinated for smallpox nor had any contact with buffaloes or history of any poxvirus disease, is suggestive of occurrence of subclinical infection. A few children who had no contact with infected animals also showed clinical manifestations with disseminated lesions on the face, arm and buttocks, and thus suspected to have acquired infection through their infected parents or other family members indicating a possible man to man transmission. Therefore, in the light of discontinuation of smallpox vaccination, buffalopox outbreaks need to be monitored carefully as this may emerge as a serious zoonotic disease in India.

RÉSUMÉ

Anti-idiotypic antibodies (anti-Ids, Ab2s) were prepared by immunizing rabbits with two murine monoclonal antibodies (Ab1) having specificities for two independent haemagglutinin (HA) epitopes on JE virus [viz., Hs-1, monoclonal antibody (MAb) specific for Japanese encephalitis virus (JEV) and Hx-1, MAb common to flaviviruses]. Anti-Hs-1 (S-Ab2) and Anti-Hx-1 (X-Ab2) reacted specifically with the immunizing Ab1. In addition, they could react with other MAbs whose reactivity was similar to their immunizing homologous Ab1. The paratope inhibition assay indicated that both anti-idiotypes recognized paratope related idiotopes on their respective Ab1 and could therefore be designated as Ab2 beta. Experimental animals (Swiss mice, Balb/c mice and guineapigs) immunized with S-Ab2 or X-Ab2 produced anti-JE virus antibodies (Ab3) which could be detected by enzyme linked immunosorbent assay, immunofluorescence, haemagglutination inhibition and neutralization tests. The anti-idiotypes were also found to stimulate a cellular immune response in vitro as assessed by 3H thymidine incorporation by lymphocytes from JE vaccinated individuals and experimentally immunized Balb/c mice. The findings of the present study suggest that both the anti-Id antibodies are homobodies which may act as surrogate antigens to manipulate the immune response against JEV.

RÉSUMÉ

6-MFA, an extract from the fungus Aspergillus ochraceus was administered to 8 bonnet macaques. An equal number of monkeys matched for age, sex and weight received placebo and served as controls. Twenty hours after the administration of the 6-MFA/placebo the monkeys were challenged with an Indian strain of Japanese encephalitis virus by the intranasal route. Signs and symptoms of the disease such as fever, tremors, loss of appetite, dehydration, flaccid paraplegia or quadriplegia were pronounced in all the control monkeys, while in the 6-MFA treated group only two developed symptoms. Virus could be isolated from only one of the 6-MFA treated monkeys on day 6, and from four control monkeys; one each from CSF, spinal cord, blood and from both nasal swab and blood of the fourth monkey. The appearance of HI and N antibodies in 6-MFA treated group was either delayed or completely suppressed. The results indicate that 6-MFA is a potential antiviral agent which can be used to reduce the morbidity and mortality in bonnet macaques (Macaca radiata) experimentally infected with Japanese encephalitis virus.
