Mycoplasma synoviae (MS) is an important avian pathogen that can cause both respiratory disease and joint inflammation synovitis in poultry, inducing economic losses to the Iranian chicken industry especially breeder farms. The aim of this study was to use the MS specific PCR and culture methods in order to detect of M. synoviae from breeder farms where located in Tehran province. A total of 47...

Pathogens of veterinary and medical importance were investigated in 240 feral pigeons (Columba livia) captured in warehouses in São Paulo State, Brazil for one year. Rapid serum agglutination test (RST) was performed for the detection of antibodies against Mycoplasma synoviae, Mycoplasma gallisepticum and Salmonella Pullorum/ Gallinarum. Positive samples were submitted to hemagglutination inhib...

BACKGROUND Mycoplasma synoviae is an avian pathogen that can lead to respiratory tract infections and arthritis in chickens and turkeys, resulting in serious economic losses to the poultry industry. Enolase reportedly plays important roles in several bacterial pathogens, but its role in M. synoviae has not been established. Therefore, in this study, the enolase encoding gene (eno) of M. synovia...

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 int...

The present work was conducted to study the seroprevalence of Salmonella, Mycoplasma gallisepticum (MG), and Mycoplasma synoviae (MS) infection in backyard chickens located in Entre Ríos, Argentina, over 3 periods of time. A total of 2,441 sera samples were collected from backyard chickens belonging to 256 family farms in 16 counties in the state of Entre Ríos from January to May 2003 (first pe...

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...

We describe a method for the simultaneous identification of up to three Mycoplasma species by the use of contrast-labeled fluorescent antibodies against two species and peroxidase-labeled antibody against a third species. The procedure enabled the rapid identification of colonies of three artificially mixed avian Mycoplasma species on agar blocks and also mixtures of species in cultures from na...

Mycoplasma synoviae (M. synoviae) can cause respiratory disease, synovitis, peritonitis, egg apical abnormalities or a subclinical infection. The importance of M. synoviae is well established in broilers but only a few studies have been conducted in layers. In the present study, the prevalence of M. synoviae in commercial layer flocks was determined by ELISA using egg yolk antibodies. Subsequen...
