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)
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 MgSO(4) or 0.85% NaCl). The lyophilized vaccines showed an expiry period of 24-26 days at(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 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)
Peste des petits ruminants (PPR) is an acute, highly contagious, notifiable and economically important transboundary viral disease of sheep and goats. In this study, sequence and phylogenetic analyses of structural protein genes, namely the nucleocapsid (N), the matrix (M), the fusion (F) and the haemagglutinin (H) coding sequences of virulent and vaccine(More)
Both conventional and real time PCR (rt-PCR) assays based on the amplification of a 103bp fragment from the DNA polymerase (DNA pol) gene (conserved, non-structural) of Orf virus (ORFV) were developed for detection and semi-quantitation of ORFV DNA from infected cell culture and clinical samples. The latter technique was based on TaqMan chemistry. The(More)
In this study, three outbreaks of peste des petits ruminants (PPR) in goats and sheep flocks with high morbidity and considerable mortality were recorded at Jhansi and Revati in Uttar Pradesh and Bhopal in Madhya Pradesh, India during 2003-2006. Clinical samples were collected from the affected flocks for laboratory investigation. The PPR virus (PPRV)(More)
Thirteen orf virus (ORFV) isolates from natural outbreaks in sheep and goats belonging to different geographical regions of India were analysed on the basis of ORF108 (a homologue of poxviral A32 gene), which is known to encode for ATPase and involved in virion DNA packaging. Comparative sequence analysis of ATPase proteins revealed highly conserved(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)
Camelpox is a contagious viral skin disease that is mostly seen in young camels. The disease is caused by the Camelpox virus (CMLV). In the present study, a polymerase chain reaction (PCR) assay based on the C18L gene (encoding ankyrin repeat protein) and a duplex PCR based on the C18L and DNA polymerase (DNA pol) genes were developed. The former assay(More)
