Peste-des-petits-ruminants (PPR) is a contagious and highly devastating disease of small ruminants. For control of endemic PPR, adequate supply of affordable and reliable diagnostics is critical for effective surveillance, along with the use of highly efficacious live vaccines that are currently available. The nucleocapsid (N) protein of PPR virus (PPRV) is an important candidate antigen for developing specific diagnostic, as it is a major viral protein being highly immunogenic and conserved among the structural proteins. In the present study, we expressed the N protein of PPRV (Sungri/96 strain), in baculovirus expression system and purified using affinity column chromatography. The recombinant protein reacted well with PPRV anti-N monoclonal antibodies and PPRV-specific polyclonal antiserum, suggesting that the expressed protein was authentic and in native form. The recombinant protein was evaluated as antigen in the diagnostic ELISA as reference positive control in place of whole virus antigen. The utility of recombinant PPRV N protein circumvents the need to use live PPRV antigen in the routinely used diagnostics targeting â€~N’ protein of PPRV, thus allowing large-scale field application of the test.

Higher vegetable production can be achieved by adoption of all the recommended technologies by large number of farmers. Adoption of vegetable production technology was studied during 2004-09 at Kullu district of Himachal Pradesh. Majority of the farmers showed low level of overall adoption of recommended technology. Weedicide application in nursery, weedicide application in main field, plant population, seed treatment with fungicides, organic manure application and nursery area were not adopted by the majority of the farmers. Non ovailability of high-yielding varieties, High cost of labour, Lack of awareness of new technology and weak extension activities at the village level were the major constraints faced by the farmers. Therefore, it was necessary to intensify the extension efforts to increase their knowledge level and adoption of recommended vegetable technologies, which would help in increasing the yield, of vegetable at farm level.

Not Available Foot-and-mouth disease (FMD) is a devastating acute viral disease of livestock with cloven hooves. Among various therapeutic control measures, RNA interference (RNAi) is one of the methods being explored to inhibit FMD virus replication and spread. The RNAi is achieved by short hairpin RNAs or artificial microRNAs (amiRNAs). Utility of amiRNAs as antiviral, targeting conserved regions of the viral genome is gaining importance. However, delivery of miRNA in vivo is still a challenge. In this study, the efficacy of amiRNAs in preventing FMD virus replication in a permissive cell culture system was investigated, by generating stable cell lines expressing amiRNAs targeting three functional regions of the FMD virus (FMDV) genome (IRES, 3B3 and 3D). The results showed that amiRNA targeting 3D polymerase is relatively more efficient. However, expression of multiple microRNAs targeting the three regions did not exhibit additive effect. The data suggest that 3D specific miRNA is a potential valid strategy in developing novel antiviral measures against FMDV infection.

Based on Likert’s summative rating technique of scaledevelopment, a scale was constructed in the year 2020 to measure the attitude of animalhusbandry personnel toward using the ICAR-IVRI Crystoscope. The scale consisted offinal 16 statements, including 8 positive and 8 negative statements. Reliability of the scalewas calculated using Cronbach’s alpha method which was found to be 0.824 and reflectsthe high reliability of the measuring instrument. The validity of the scale was tested byexpert’s judgment. The reliability and validity of the scale indicate its consistency andprecision of the results. This scale can be used to measure the attitude of animal husbandrypersonnel in similar situation beyond the study area with suitable modifications. Not Available |
