Beak and feather disease virus is the dominant viral pathogen of Psittaciformes in Australasia, where it has been present for at least 10 million years, [16] and Australia has been identified as the most likely origin of the virus. [18] The richness of psittacine avifauna in this region has produced a mixture of potential hosts for the ...
The virus Psittacid alphaherpesvirus 1 is the etiologic agent that causes Pacheco's disease. This virus species is closely related to Gallid alphaherpesvirus 1. [2] It was initially identified as a herpesvirus by examining its virion size, sensitivity to ether, the formation of intranuclear inclusions, its ability to thicken the nuclear membranes of the host cells.
Proventricular dilatation disease (PDD) is an incurable probably viral disease of psittacine birds. It was first recognized and described in 1978 by Dr. Hannis L. Stoddard. Since the first reported cases were involving species of macaw, the condition was termed macaw wasting syndrom
Psittacosis—also known as parrot fever, and ornithosis—is a zoonotic infectious disease in humans caused by a bacterium called Chlamydia psittaci and contracted from infected parrots, such as macaws, cockatiels, and budgerigars, and from pigeons, sparrows, ducks, hens, gulls and many other species of birds.
Chlamydia psittaci serovar A is endemic among psittacine birds and has caused sporadic zoonotic disease in humans, other mammals, and tortoises. Serovar B is endemic among pigeons , has been isolated from turkeys , and has also been identified as the cause of abortion in herds of dairy cattle .
Iltovirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Alphaherpesvirinae.Birds, galliform birds, psittacine birds, chickens, turkeys, and quail serve as natural hosts.
African swine fever virus (ASFV) is a large double-stranded DNA virus which replicates in the cytoplasm of infected cells and is the only member of the Asfarviridae family. The virus causes a lethal haemorraghic disease in domestic pigs. Some strains can cause death of animals within as little as a week after infection.
The grey parrot has been known to contract beak and feather disease virus (BFDV) which causes a highly contagious, and sometimes fatal, psittacine beak and feather disease in parrots. [19] In a PCR-based study, Chlamydiosis, an infectious disease of avians, was found to infect the grey parrot.
