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
These birds were carefully monitored over extended periods, well exceeding the documented 90-day inoculation period for PDD, yet failed to show any signs of PDD. [8] However, the differences in responses to the experimental infections may be associated to ABV strain variation in pathogenicity, the chronic nature of the infection and the ...
Psittacine beak and feather disease was first described in the early 1980s and has become recognised as the dominant viral pathogen of psittacine birds worldwide. In wild red-rumped grass parakeets (Psephotus haematonotus), a case of feather loss syndrome that was highly suggestive of PBFD was first recorded in South Australia in 1907. [2]
Bird flu is a scary illness with a high mortality rate. But so far, infections in the U.S. have been relatively mild—until now. A patient in Louisiana has been hospitalized with a severe case of ...
Borna disease, also known as sad horse disease, [1] is an infectious neurological syndrome [2] of warm-blooded animals, caused by Borna disease viruses 1 and 2 (BoDV-1/2). BoDV-1/2 are neurotropic viruses of the species Mammalian 1 orthobornavirus, and members of the Bornaviridae family within the Mononegavirales order.
What are the symptoms? What to know about highly pathogenic avian influenza, aka, H5N1. A person in Louisiana has been hospitalized with a possible case of human bird flu
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.
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.
