background and aims: a multiplex transcription-polymerase chain reaction (m-pcr) was developed for direct detection and discrimination between canarypox virus (cpv) and other avian poxvirus (apv). materials and methods: three compatible primer sets were designed for m-pcr amplification of different loci fpv126, fpv140, and fpv167 located at highly conserved apv genes. results: results showed th...

Between January 2002 and November 2003, 50% (n = 395) of short-toed larks (Calandrella rufescens) and 28% (n = 139) of Berthelot's pipits (Anthus berthelotti) examined on the islands of Fuerteventura and Lanzarote, Canary Islands, had gross lesions compatible with avian pox. However, Spanish sparrows (Passer hispaniolensis, n = 128) and trumpeter finches (Bucanetes githagineus, n = 228), which ...

Experiments are reported in which it was shown that rabbits which had recovered from experimental or spontaneous rabbit pox were refractory to inoculation of pox virus injected by various routes, and in addition did not develop clinical manifestations of the disease under conditions of exposure to florid cases of pox. It was found that pox recovered rabbits were susceptible to inoculation with ...

Sheeppox virus (SPPV) and goatpox virus (GTPV) are the causative agents of sheep pox and goat pox, and with lumpy skin disease virus make up the genus Capripoxvirus in the family Poxviridae. Sheep pox and goat pox are endemic in Africa north of the Equator, the Middle East and Asia, while some parts of Europe have experienced outbreaks recently. Countries that reported outbreaks of the disease ...

Abstract Background and Aims: For more than half a century, the production of fowl pox vaccine at Razi Vaccine and Serum Research Institute, has been carried out by injection method in the chick chorioallantoic membrane (CAM) and the vaccine has a favorable and effective in poultry flocks and has provided a complete satisfaction to the poultry flocks owner. Fowl pox vaccine is also manufactured...

Aim: To detect and differentiate Capripox virus (sheeppox virus and goatpox virus) infections by using 30 kDa RNA polymerase subunit (RPO30) gene based PCR. Materials and Methods: Two capripox viruses' viz., sheep pox virus (SPPV) and goatpox virus (GTPV) from clinical samples of different outbreaks were detected and differentiated using capri pox virus (CaPVs) genotyping PCR targeting the CaPV...

Kid kidney cells form less than 2 months of age were grown, 80% confluent monolayers were obtained after 10-12 days. Live attenuated goat pox virus vaccine (Gorgan 55, Iranian) was used to infect the confluent monolayers. Eighty percent cytopethic effect (CPE) was obtained on day 5 of virus inoculation. TCID50 calculated for the pool virus was 10 / ml. Vaccine was found free from any bacterial ...

Fowl pox is a viral disease of domestic and wild birds. The large size of the genome makes it a useful vector for recombinant DNA technology. Although the disease has been described in both commercial and indigenous chickens in Nigeria, data are limited on seroprevalence in free range chickens. Such data are, however, important in the design and implementation of fowl pox virus vector vaccine. ...
