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 purpose of this compendium is to provide information about Chlamydophila psittaci to all those concerned with the control of the disease, which had 66 reported human cases between 2005 and 2009. It includes standardized procedures to control avian chlamydiosis in birds, which causes the disease in humans.
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.
In addition, a cockatiel purchased at the flea market tested positive for avian chlamydiosis, sometimes called “parrot fever.” It is a bacterial infection that can cause the illness ...
Chlamydia is a genus of pathogenic Gram-negative bacteria that are obligate intracellular parasites. Chlamydia infections are the most common bacterial sexually transmitted diseases in humans and are the leading cause of infectious blindness worldwide.
In a PCR-based study, Chlamydiosis, an infectious disease of avians, was found to infect the grey parrot. In the study 253 clinical samples were taken from 27 bird species belonging to seven orders. Thirty-two (12.6%) samples were positive for Chlamydi and two new genotypes were discovered: Chlamydophila psittaci and Chlamydophila abortus. [20]
All Chlamydiota are anaerobic bacteria with a biphasic developmental lifecycle that depends on obligately intracellular growth in eukaryotic host cells.. Chlamydophila was recognized by a number of scientists in 1999, [3] with six species in Chlamydophila and three in the original genus, Chlamydia.
The avian immune system is the system of biological structures and cellular processes that protects birds from disease. The avian immune system resembles that of mammals since both evolved from a common reptilian ancestor and have inherited many commonalities. [1] They have also developed a number of different strategies that are unique to birds.
