Ureaplasma gallorale is a species of Ureaplasma, a genus of bacteria belonging to the family Mycoplasmataceae.[1] It has been isolated from chickens and barnyard fowl. It possesses the sequence accession no. (16S rRNA gene) for the type strain: U62937.[2][3] It is a commensal species with its host organism but has the ability to colonize and create infection. In the presence of virulence factors (H2O2, antigen proteins, etc.) is when these species start to over colonize .[4] They have relatively small genomes, utilizing their host organisms natural processes to further their growth and survival.[4] Nutrient required by the Ureaplasma species to continue metabolism are taken directly from the host. They proliferate in environments with a pH of 6.0-6.5 and a temperature of 35-37 °C.[5] These characteristics are common to most biological environments which is why Ureaplasma species regularly cause infection. These infections can be found in the genital and respiratory tracks of avian species (chickens and turkey). Ureaplasma gallorale infections cannot always be managed by the host due to the mechanisms the bacteria have adapted. A host will release immune signals of IgA molecules to the bacterial cells to signify infection but the Ureaplasmas can secrete an enzyme known as IgAse that destroys IgA, rendering the signal inactive and leaving the host susceptible to health concerns.[4] These infections, known as the condition Ureaplasmosis, have further ramifications for the barnyard fowl such as low egg production, weight loss, reduced feed conversion efficiency and even death.[6] These health issues are a serious concern in maintaining adequate production for the agricultural industry.[citation needed]
