Chlamydia psittaci is a lethal intracellular bacterial species that may cause endemic avian chlamydiosis, epizootic outbreaks in other mammals, and respiratory psittacosis in humans. Potential hosts include feral birds and domesticated poultry, as well as cattle, pigs, sheep, and horses.
Psittacosis was first reported in Europe in 1879. [9] In 1929, a highly publicized outbreak of psittacosis hit the United States. Although not the first report of psittacosis in the United States, it was the largest up to that time. It led to greater controls on the import of pet parrots. [9]
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.
Bird fancier's lung (BFL), also known as bird breeder's lung, is a type of hypersensitivity pneumonitis.It can cause shortness of breath, fever, dry cough, chest pain, anorexia and weight loss, fatigue, and progressive pulmonary fibrosis (the most serious complication).
Chlamydophila psittaci, which causes psittacosis; The unique physiological status of the Chlamydiota including their biphasic lifecycle and obligation to replicate within a eukaryotic host has enabled the use of DNA analysis for chlamydial diagnostics. [37] Horizontal transfer of genes is evident and complicates this area of research.
For example, at that time genus C. psittaci was distinguished from C. trachomatis by sulfadiazine resistance, although not all strains identified as C. psittaci at the time were resistant, and C. pneumoniae was classified by its appearance under electron microscopy (EM) and its ability to infect humans, although the EM appearance may differ ...
DES MOINES, Iowa (AP) — More than 4 million chickens in Iowa will have to be killed after a case of the highly pathogenic bird flu was detected at a large egg farm, the state announced Tuesday.
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.
