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 ...
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.
The virus has sickened 55 people in the U.S.
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 ...
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]
Since the outbreak in cows was announced in late March, bird flu has been detected in 33 dairy herds in nine states: Colorado, Idaho, Kansas, Michigan, New Mexico, North Carolina, South Dakota ...
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.
