The psittacine beak and feather disease (PBFD) is a globally widespread infectious bird disease that mainly affects species within the Order Psittaciformes (parrots and allies). The disease is caused by an avian circovirus (the beak and feather disease virus, BFDV), which is highly infectious and...

Although parrot species are infrequently infected by hemoparasites in the wild, some fatal infections have been reported in captive individuals. Conversely birds of prey are frequently infected by hemoparasites. In this study, 193 captive birds from Convention on International Trade in Endangered...

The mosquito-borne flavivirus Usutu virus (USUV) is responsible for countless deaths in both resident populations and birds kept in outdoor aviaries. Since 2001, USUV outbreaks have attracted increased attention due to the rapid geographical spread of the virus and its close relationship to West...

Confiscated parrots are frequently introduced to captive populations in zoological institutions, regularly with insufficient health screening. This short communication describes a case where 25 confiscated parrots, from four different locations, were brought to the same zoological institution...

In Thailand a proventricular dilation disease (PDD)-like syndrome commonly occurs in captive psittacine birds. The etiology, however, has been unknown to date and studies to detect parrot bornaviruses have never been performed in Southeastern Asia. Therefore, 111 psittacines (22 different species)...

Conservation efforts for the orange-bellied parrot (Neophema chrysogaster), one of the world's most critically endangered bird species, have been hampered by beak and feather disease virus (BFDV) spillover infection. To understand the vulnerability of orange-bellied parrots to potential reservoirs...

To assess the prevalence of adenoviruses in psittacine birds kept in Slovenia, 258 cloacal swabs were collected from different psittacine species and screened by a nested PCR with degenerate, consensus primers targeting the adenoviral DNA polymerase gene. Forty-two samples were found to be...

More than 16% of parrot species (Aves Psittaciformes) of the world have currently established at least one breeding population outside their natural distribution ranges. Though including the most introduced bird species all over the world, their interactions with native biodiversity and...

This work contains information on the aetiology, epidemiology, prevalence, transmission, risk factors, clinical signs, diagnosis, treatment, prevention, control and recommendations for viral, bacterial, fungal and parasitic zoonotic diseases in rodents (rats, mice, hamsters, gerbils, guineapigs and ...

Circovirus is a non-enveloped, single-stranded DNA virus and the etiological agent of avian circovirus, that commonly affects parrots causing Psittacine Beak and Feather Disease (PBFD). The disease is highly contagious and lethal, being considered exotic in Brazil. The aim of the present review is...
