Indian Veterinary Research Institute or IVRI is located at Izztnagar, Bareilly in Uttar Pradesh state. It is India's premier advanced research facility in the field of veterinary medicine and allied branches. It has regional campuses at Mukteshwar, Bangalore, Palampur, Bhopal, Kolkata and Srinagar. Formerly known as Imperial Bacteriological Laboratory, it was renamed in 1925 as Imperial Veterinary Research Institute. The name of the Institute was changed following independence to Indian Veterinary Research Institute. Administrative control of the Institute is currently under Indian Council of Agricultural Research , New Delhi. The Ministry of Education, Govt. of India on the recommendation of University Grants Commission conferred the status of the Deemed to be University on 16 November 1983 under Section 3 of UGC Act .

Peste des petits ruminants (PPR) is a contagious viral disease of small ruminants. It is endemic in several African, Middle Eastern and Asian countries, including India. India has recently taken comprehensive steps to deal with PPR through the development and production of potent vaccines and monoclonal-antibody-based diagnostic kits, while also gathering baseline information on the disease situation and human resources. As a result, PPR can now be controlled by focused vaccinations in high-risk populations of sheep and goats, followed by mass vaccination campaigns. Mass vaccination campaigns must achieve high levels of herd immunity (70% to 80%) to block the epidemic cycle of the virus. With the tools currently available, disease control and subsequent eradication programmes for PPR may be a feasible option, following the example of the National Rinderpest Eradication Programme, which has successfully eradicated rinderpest from India. An understanding of the cultural and socio-economic circumstances of goat and sheep owners and a keen watch on the endemic nature of PPR in neighbouring countries will enhance the success of this approach. Coordinated efforts from all stakeholders, combined with proper funding and execution of control programmes, will be needed to achieve the goal of a PPR-free India. In addition, the availability of effective combined vaccines of PPR with goat pox or sheep pox offers a cost-effective way of simultaneously launching control programmes against all three of these diseases.

The family Poxviridae includes several viruses of medical and veterinary importance. Global concerted efforts combined with an intensive mass-vaccination campaign with highly efficaceious live vaccine of vaccinia virus have led to eradication of smallpox. However, orthopoxviruses affecting domestic animals continue to cause outbreaks in several endemic countries. Different kinds of vaccines starting from conventional inactivated/attenuated to recombinant protein-based vaccines have been used for control of poxvirus infections. Live virus homologous vaccines are currently in use for diseases including capripox, parapox, camelpox and fowlpox, and these vaccines are highly effective in eliciting (with the exception of parapoxviruses) long-lasting immunity. Attenuated strains of poxviruses have been exploited as vectored vaccines to deliver heterologous immunogens, many of them being licensed for use in animals. Worthy of note are vaccinia virus, fowlpox virus, capripoxvirus, parapoxvirus and canary pox, which have been successfully used for developing new-generation vaccines targeting many important pathogens. Remarkable features of these vaccines are thermostability and their ability to engender both cellular and humoral immune responses to the target pathogens. This article updates the important vaccines available for poxviruses of livestock and identifies some of the research gaps in the present context of poxvirus research.

Hemorrhagic septicemia (HS), an acute, fatal and septicemic disease of cattle and buffaloes caused by Pasteurella multocida, is important in tropical regions of the world, especially in African and Asian countries. The prevalence of disease has been well documented with predominant isolation of P. multocida serotypes B:2 and E:2. Conventional methods of identification such as serotyping, biotyping, antibiogram determination and pathogenicity as well as molecular methods (P. multocida-specific polymerase chain reaction (PCR), a serogroup B-specific PCR assay, multiplex capsular typing system and loop-mediated isothermal amplification techniques) and characterization (restriction endonuclease analysis, randomly amplified polymorphic DNA analysis, repetitive extragenic palidromic PCR and enterobacterial repetitive intergenic consensus PCR analysis) are applied in parallel for rapid epidemiological investigations of HS outbreaks. Although several vaccine formulations including alum precipitated, oil adjuvant and multiple emulsion vaccines are commercially available, the quest for suitable broadly protective HS vaccines with long-lasting immunity is on the upsurge. Concurrently, attempts are being made to unravel the mysteries of the pathogen and its virulence factors, pathogenesis and determinants of protective immunity as well as diversity among strains of P. multocida. This review highlights the advances in these various aspects of HS.

This study investigated the anti-neoplastic potential of avian reovirus σC (sigma C) protein on Rous sarcoma virus-induced fibrosarcoma in chicken. The recombinant vector expressing σC protein was injected intra-tumorally into specific pathogen free chicken with fibro-sarcoma at the dose 100μg per bird, while control birds were mock-treated with 100μg of empty vector per bird. Recombinant σC protein induced apoptosis in tumors of treated birds resulting in progressive tumor regression, while similar changes were absent in tumors of mock-treated controls. The σC protein-induced apoptosis in tumors was quantified by flow cytometry and the mean level of apoptosis up to 66% was observed in treated tumors, whereas any significant level of apoptosis was absent in mock-treated controls.

Contents: The present review addresses summer anoestrus in buffaloes. The condition is a major impediment in the improvement of reproductive as well as productive efficiency in buffalo. Factors affecting summer anoestrus include environment, nutrition and management. The environmental factors especially longer day length and increased temperature with high humidity pre-dispose to the condition when the nutritive status of buffaloes is poor. Buffaloes with summer anoestrus fail to exhibit oestrus as a result of aberration in the endocrine profile leading to ovarian inactivity. Increased day length with high environmental temperature causes hyper-prolactinaemia, suppressing the secretion of gonadotrophins, which leads to an alteration in ovarian steroidogenesis. Heat stress produced during summer also affects folliculogenesis, follicular fluid microenvironment and oocyte quality. A large number of hormonal regimens have been used with varying degree of efficacy in terms of oestrus induction and conception rate. A combined strategy of improvement in environment, nutrition and management is pre-requisite for hormonal manipulation in order to improve productivity in summer anoestrus buffaloes. A brief description of summer anoestrus with special reference to factors responsible, endocrinology, deleterious effects on reproductive system and possible remedial measures is presented in this review. © 2010 Blackwell Verlag GmbH.
