Chicken Anaemia Virus in Sparrows in Iran
نویسندگان
چکیده
Circoviridae family contains two genuses. Chicken anaemia virus (CAV) is the only member of the genus Gyrovirus, while the genus Circovirus currently comprises porcine circoviruses type 1 and 2 (PCV1, PCV2), psittacine beak and feather disease virus (BFDV), pigeon circovirus (PiCV), canary circovirus (CaCV), goose circovirus (GoCV) and duck circovirus (DuCV) [24]. Members of circoviridae family are non-enveloped, regular icosahedrons and are the only animal viruses with a circular, single-stranded DNA genome [27]. These viruses share many epizootiological and pathological similarities (i.e. young age of affected animals, particular tropism for lymphoid tissue and organs, related acquired immunosuppression and secondary infections) [2, 21].

Chicken infectious anaemia is a viral disease in young chickens which characterized by aplastic anaemia and immunosuppression. Between January 2004 and July 2005, an unusual hemorrhage in subcutaneous and intramuscular tissues of broiler chickens at slaughter houses of Mashhad, Isfahan and Tehran provinces were occurred. Postmortem examination revealed severe hemorrhages in the wings and muscle...

Avian influenza (AI) is an acute infectious disease with worldwide significance causing extensive economic losses in the poultry industry. Avian influenza viruses (AIVs) belong to the family Orthomyxoviridae and categorized in the genus influenza virus A. These viruses have been isolated from more than 100 species of free-living birds. Migratory birds are considered as reservoirs for AIVs and a...
متن کاملInfectivity and transmissibility of H9N2 avian influenza virus in chickens and wild terrestrial birds
Genetic changes in avian influenza viruses influence their infectivity, virulence and transmission. Recently we identified a novel genotype of H9N2 viruses in widespread circulation in poultry in Pakistan that contained polymerases (PB2, PB1 and PA) and non-structural (NS) gene segments identical to highly pathogenic H7N3 viruses. Here, we investigated the potential of these viruses to cause di...
متن کاملA Survey of Neospora caninum infection in sparrows (Passer domesticus) in Khuzestan Province, Iran
The present study reports the presence of N. caninum DNA by PCR in brain tissues of house sparrows. The results showed that 6 (2.8%) of brain samples were positive for N. caninum. This is the first report for detection of N. caninum in sparrows, in Khuzestan Province. The results suggest that the meat of infected sparrows can be the source for dogs' infection.
