mycoplasmosis is one of the most important diseases in the poultry industry. its causative agent, mycoplasma has various species, which two of them, mycoplasma gallisepticum (mg) and mycoplasma synoviae (ms) are the most important species. due to the enormous losses in the production farms of industrial poultry, achieving a rapid, accurate and definite diagnosis of mycoplasma is of great import...

Mycoplasma synoviae strain MS-H, developed by chemical mutagenesis of the Australian field strain 86079/7NS, is a live temperature-sensitive (ts (+)) vaccine used for control of M. synoviae infection in poultry worldwide. Genetic basis of temperature sensitivity and attenuation of MS-H has not been revealed thus far. Comparison of the complete genome sequence of MS-H, its parent strain 86079/7N...

This study aimed to investigate Mycoplasma species in the lungs of 500 geese with pneumonia from Kars region (Turkey) via cultural and molecular methods. The samples were cultured on Frey’s Broth Agar media. To identify a Growth Inhibition Test was used. identification continued species-specific PCR sequence analysis which provide amplification genes dnaX, pcrA, rpoB, 16S rRNA gene, respectivel...

Mycoplasma gallisepticum is a bacterial pathogen of poultry that is estimated to cause annual losses exceeding $780 million. The National Poultry Improvement Plan guidelines recommend regular surveillance and intervention strategies to contain M. gallisepticum infections and ensure mycoplasma-free avian stocks, but several factors make detection of M. gallisepticum and diagnosis of M. gallisept...

Disease caused by Mycoplasrna s11noviae, so far called infectious synovitis, shows symptoms such as joint swelling, lameness, pale comb, and retarded growth mainly of chicken and turkey. This disease, first noticed in a broiler raising area of U.S.A., was reported by Olson et al. and Wills in 1954. Since then the disease has been recognized in European countries and South Africa•>. In Japan, al...

21 Mycoplasma gallisepticum is a bacterial pathogen of poultry that is estimated to cause 22 annual losses exceeding $780 million. The National Poultry Improvement Plan guidelines 23 recommend regular surveillance and intervention strategies to contain M. gallisepticum 24 infections and ensure mycoplasma-free avian stocks, but several factors make its detection 25 and diagnosis a major challeng...
