BACKGROUND Mycoplasma synoviae causes infectious synovitis and respiratory diseases in chickens and turkeys and may lead to egg shell apex abnormalities in chickens; hence possesses high economic impact on the poultry industry. Control of the disease consists of eradication, vaccination or medication. The aim of the present study was to determine the in vitro susceptibility to 14 different anti...

We have analyzed the sequenced genomes of three strains of Mycoplasma hyopneumoniae and one strain of M. synoviae, and have found three and two different transposable element families, respectively in each species. In M. hyopneumoniae, the Insertion Sequences of the IS4 family is represented by ISMHp1, a putatively active element. The IS3 family is represented by several degenerated sequences. ...

State wildlife agencies have translocated thousands of wild turkeys (Meleagris gallopavo) since the 1930s to reestablish this species. Because of threats to the domestic poultry industry and wild birds, screening for selected infectious agents has become routine since the early 1980s. One of the principal sources for Rio Grande wild turkeys (M. gallopavo intermedia) for translocation purposes w...

A reservoir of pseudogene alleles encoding the primary adhesin VlhA occurs in the avian pathogen Mycoplasma synoviae. Recombination between this reservoir and its single expression site was predicted to result in lineages of M. synoviae that each express a different vlhA allele as a consequence of host immune responses to those antigens. Such interstrain diversity at the vlhA expression site, i...

detection of mycoplasma synoviae (ms) by culture and polymerase chain reaction (pcr) has been reported from commercial chicken farms in different provinces of iran. in some reports the phylogenetic analysis of ms isolates based on 16s rrna and variable lipoprotein hemagglutinin (vlha) genes have been carried out. the pcr product containing partial 16s rrna genes of iranain isolates was sequence...
