Members the Potyviridae family belong to a group of plant viruses that are causing devastating plant diseases with a significant impact on agronomy and economics. Plum pox virus (PPV), as a causative agent of sharka disease, is widely discussed. The understanding of the molecular biology of potyviruses including PPV and the function of individual proteins as products of genome expression are qu...

The aim of the study was to find out the host specificity of pigeon pox virus-1 (PPV-1) and fowl pox virus-2 (FPV-2) following cross infection with field strains from Bangladesh. The cross infection was investigated in five groups (n=5) of pigeons and seven groups of chickens (n=5) four weeks of age. Irrespective of route of inoculation each bird received either 0.1 mL of PPV-1 or FPV-2 having ...

This study was conducted for explaining the use of combined inactivated pneumo-3 vaccine (bovine viral diarrhea, bovine herpes virus -1 and parainfleunza-3 viruses) as a diluent for sheep pox virus vaccine to be used as a vaccine for goats in one shot. 16 balady adults’ male goats were used which were seronegative against each virus used in this study. All goats were randomly divided into four ...

Background: Avipox virus considered to be a contagious disease of many types of birds wild and domestic. The current study focused on the isolation of recently common Avipox virus which include fowl pox (FP) and pigeon pox (PP) viruses in Iraq. Materials & methods: Isolation of the viruses was done via chorioallantoic membrane (CAM) route of avian embryo inoculation, also used by a chicken fibr...

BACKGROUND Invasive parasites are a major threat to island populations of animals. Darwin's finches of the Galápagos Islands are under attack by introduced pox virus (Poxvirus avium) and nest flies (Philornis downsi). We developed assays for parasite-specific antibody responses in Darwin's finches (Geospiza fortis), to test for relationships between adaptive immune responses to novel parasites ...

To investigate an outbreak of avian pox in psittacines in a conservation facility, we examined 94 birds of 10 psittacine species, including sick and healthy birds. We found psittacine pox virus in 23 of 27 sick birds and 4 of 67 healthy birds. Further characterization is needed for these isolates.

HREE live poultry viruses-fowl pox, Rous sarcoma and Newcastle diseasehave been employed experimentally at the Agricultural Research Center, Beltsville, Maryland, iin studies designed to test their action on parthenogenesis in eggs of Beltsville Small White (BSW) turkeys. Each of the viruses was found to have an enhancing influence on cells of parthenogenetic origin (OLSEN 1956, 1961; OLSEN and...

The Chrysodeixis chalcites single nucleopolyhedrovirus (ChchSNPV) infects and kills C. chalcites larvae, an important pest of banana crops in the Canary Islands. Five genotypes present in the most prevalent and widespread isolate in the Canary Islands were sequenced, providing genetic data relevant to the genotypic and phenotypic diversity of this virus.

Identifying the key factors underlying the spread of a disease is an essential but challenging prerequisite to design management strategies. To tackle this issue, we propose an approach based on sensitivity analyses of a spatiotemporal stochastic model simulating the spread of a plant epidemic. This work is motivated by the spread of sharka, caused by plum pox virus, in a real landscape. We fir...
