Chlamydophila felis was then reclassified to Chlamydia felis due to dispute on the taxonomic usage of Chlamydophila, which is still disputed to this day. [3] C. felis is found worldwide. [ 9 ] It has been reported to infect humans as well, giving it zoonotic potential, though it is rare. [ 9 ]
Chlamydophila was recognized by a number of scientists in 1999, [3] with six species in Chlamydophila and three in the original genus, Chlamydia. This was immediately seen as controversial. [4] In 2015 the Chlamydophila species were reclassified as Chlamydia. [4] The history of the classification and reclassification is as follows.
Chlamydia psittaci serovar A is endemic among psittacine birds and has caused sporadic zoonotic disease in humans, other mammals, and tortoises. Serovar B is endemic among pigeons, has been isolated from turkeys, and has also been identified as the cause of abortion in herds of dairy cattle.
[6] [7] [8] C. felis infection is limited to the family Felidae which means that C. felis poses no zoonotic (transmission to humans) risk or agricultural (transmission to farm animals) risk. Until recently it was believed that after infection with C. felis, pet cats almost always died.
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.
Chlamydophila pneumoniae, which causes a form of pneumonia; 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]
The bacterial order Chlamydiales includes only obligately intracellular bacteria that have a chlamydia-like developmental cycle of replication and at least 80% 16S rRNA or 23S rRNA gene sequence identity with other members of Chlamydiales.
A feline zoonosis is a viral, bacterial, fungal, protozoan, nematode or arthropod infection that can be transmitted to humans from the domesticated cat, Felis catus. Some of these diseases are reemerging and newly emerging infections or infestations caused by zoonotic pathogens transmitted by cats. In some instances, the cat can display ...
