Avian Mycoplasmosis: A Review
ثبت نشده
چکیده
Avian mycoplasmosis is an important disease of poultry of great economic importance. It is caused by four (4) pathogenic mycoplasma species namely Mycoplasma gallisepticum, Mycoplasma synoviae, Mycoplasma meleagridis and Mycoplasma iowae; although other Mycoplasma species have also been incriminated in the disease. The disease causes cough, rales, ocular and nasal discharges, decreased feed intake, decreased feed conversion, decreased egg production and hatchability. Avian mycoplasmosis can lead to a significant reduction in egg production of between 10-20% in infected layer and broiler breeder flocks. It also causes infectious sinusitis in turkeys. It can be prevented and controlled by the acquisition of birds free from mycoplasma, maintenance of replacements from mycoplasma free sourcesin a single-age, all in all out management system, proper hygiene and biosecurity measures. More interest in the research of this disease should be encouraged especially in Nigeria as there is presently very little literature available on avian mycoplasma research in Nigeria.

Diagnosis of Avian Mycoplasmas: A Comparison between PCR and Culture Technique
Mycoplasma gallisepticum and Mycoplasma synoviae are the causative agents of avian mycoplasmosis in commercial poultry. Among the available tools, polymerase chain reaction (PCR) and culture are confirmatory tools for the diagnosis of mycoplasmosis after the initial serological screening of suspected birds. Overall, 181 samples were analyzed, 152 (84%) and 103 (57%) of which were found positive...

Since 1954, avian mycoplasmosis has been considered a significant problem in chicken flocks in Japan and in other Asian countries. In Japan, Mycoplasma gallisepticum (MG) and M. synoviae (MS) infections were confirmed aetiologically in chicken flocks affected with respiratory disease or synovitis in 1962 and 1973, respectively. In other Asian countries, including Indonesia, the People's Republi...

متن کاملAvian Mycoplasmosis Update
Avian mycoplasmas occur in a variety of bird species. The most important mycoplasmas for chickens and turkeys are Mycoplasma gallisepticum (MG), M. synoviae (MS), and M. meleagridis. Besides, M. iowe (MI) is an emerging pathogen in turkeys, but of little concern for chickens. Mycoplasmas are bacteria that lack cell wall and belong to the class Mollicutes. Although they have been considered extr...
