Mycoplasma synoviae expressed variable lipoprotein haemagglutinin (VlhA) is believed to play a major role in pathogenesis of the disease by mediating adherence and immune evasion. The aim of this study was sequencing Iranian M. synoviae isolates for the detection of nucleotide variation in the M. synoviae vlhA gene. Using oligonucleotide primers complementary to the single-copy conserved 5´ end...

Mycoplasma synoviae is an economically important pathogen of poultry worldwide, causing respiratory infection and synovitis in chickens and turkeys. Identification of M. synoviae isolates is of critical importance, particularly in countries in which poultry flocks are vaccinated with the live attenuated M. synoviae strain MS-H. Using oligonucleotide primers complementary to the single-copy cons...

Newcastle disease is characterized by respiratory manifestations in association with nervous and/or digestive symptoms. Its prevention is done by vaccination with live attenuated (lentogenic strains) and/or killed vaccines. The lentogenic strains can lead to strong post-vaccination reaction, principally due to the presence of other pathogenic agents. Among them, Mycoplasma synoviae is worldwide...

Poultry industry has high annual growth rate in Pakistan. Mycoplasmosis, separately or in combination with other diseases, cause major setbacks to poultry industry. Due to significant role of Mycoplasmosis in poultry industry, its control programme success depends on timely and accurate diagnosis of infected flocks. Poultry flocks are generally screened for Mycoplasma by Rapid Slide Agglutinati...

A total of 459 serum samples from unvaccinated backyard chickens originating from 4 villages in Mandlakazi district, Southern Mozambique, were tested for the presence of Mycoplasma gallisepticum and Mycoplasma synoviae antibodies through commercial enzyme-linked immunoabsorbent assay [ELISA] kits. Anti-MG and anti-MS antibodies were detected in all villages surveyed and the overall seroprevalen...

At least 13 mycoplasma species cause arthritis in animals. In some cases it remains chronic, and in particular Mycoplasma hyorhinis in swine and Mycoplasma synoviae in poultry clinically and histologically resemble rheumatoid arthritis in man. Of patients with serologically verified Mycoplasma pneumoniae infections 0.9% had arthritis. Usually it is mild, but may sometimes be the dominant clinic...

11 Mycoplasmas have affected poultry production for many years and effective control of mycoplasma infection has been a fundamental stepping stone to improved performance and productivity. However, infections appear to be making a comeback. Numerous species of mycoplasmas have been isolated from avian sources. Two species are recognised as predominantly pathogenic to chickens and turkeys. Mycop...

The techniques of immunofluorescence and of transmission and scanning electron microscopy were used to demonstrate the attachment of Mycoplasma synoviae to chicken embryo fibroblasts. Although the organisms colonized the surface of many of the cells, there was marked variation in the number of organisms associated with individual cells.
