Outbreaks of buffalopox or pox-like infections affecting buffaloes, cows and humans have been recorded in many parts of the world. Since the first outbreak in India, a large number of epidemics have occurred. Unlike in the previous years, generalized forms of the disease are now rare; however, there are severe local forms of the disease affecting the udder(More)
Peste des petits ruminants (PPR) is a highly contagious, economically important viral disease of sheep and goats with high morbidity and mortality rates. In order to control the disease effectively, highly sensitive diagnostic tests coupled with potent vaccines are important pre-requisites. At present, there are three live attenuated PPR vaccines available(More)
This study describes seroprevalence of Peste des petits ruminants (PPR) in cattle and buffaloes carried out during the period 2009–2010 using the randomly collected serum samples from different parts of Southern peninsular India. The report presents the results of PPR virus (PPRV)—specific antibodies in situations where either the subclinical or inapparent(More)
Orf virus (ORFV), the type species of Parapoxvirus, is responsible for contagious ecthyma in sheep and goats. In the present report, sequence analysis of major envelope gene (B2L) of four Indian orf virus isolates originating two each from sheep and goats was carried out. These recent isolates belonged to different outbreaks that occurred in Kumaon hills(More)
In the present study, the partial gene sequences of P32 protein, an immunogenic envelope protein of Capripoxviruses (CaPV), were analyzed to assess the genetic relationship among sheeppox and goatpox virus isolates, and restriction enzyme specific PCR-RFLP was developed to differentiate CaPV strains. A total of six goatpox virus (GTPV) and nine sheeppox(More)
The present study was undertaken to express goatpox virus (GTPV) P32 protein in Pichia pastoris and evaluate its potential use as a diagnostic antigen in ELISA. The amplified P32 gene of GTPV was cloned into pPICZalphaA vector and characterized by PCR, restriction enzyme digestion and sequencing. The characterized linear recombinant plasmids were(More)
Peste des petits ruminants (PPR) is a contagious, notifiable and economically important transboundary viral disease of small ruminants. In this study, a hydrolysis probe-based real-time reverse transcription-polymerase chain reaction (rt RT-PCR) assay for the detection and semi-quantification of PPR virus (PPRV) nucleic acid was developed using the virus(More)
Sheep are the moving banks of shepherds and their economic contribution in terms of meat, wool and skin/hide is immense. Various infectious diseases jeopardize the optimum productivity; among which sheep pox is more important as the disease restricts the export of sheep and their products besides other economic losses. Although, clinical signs are(More)
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(More)
In this study, thermo-adapted (Ta) PPR vaccines were assessed for their stability at 25, 37, 40, 42 and 45°C in lyophilized form using two extrinsic stabilizers {lactalbumin hydrolysate-sucrose (LS) and stabilizer E} and in reconstituted form with the diluents (1 mol/L MgSO4 or 0.85% NaCl). The lyophilized vaccines showed an expiry period of 24–26 days at(More)
