Epidemiological study on Mycoplasma synoviae infection in layers
Veterinary Microbiology, 2006Mycoplasma synoviae infection occurs worldwide in commercial poultry flocks and may result in severe economic losses. The prevalence of this mycoplasma in standard layers older than 60 weeks was studied in a French department and the characteristics of infected or free flocks were compared.

Pneumonia of Turkey Breeder Hens Associated with Mycoplasma Synoviae
Avian Diseases, 2007Turkey breeder hens showed an increase in mortality beginning at 38 wk of age with no other clinical signs or changes in egg production. While no respiratory signs were observed in live turkeys, those that died consistently had gross lesions of pneumonia.

Multilocus sequence analysis forMycoplasma synoviaemolecular genotyping
British Poultry Science, 2015The aim of this study was to identify molecular techniques which enable clear discrimination between Mycoplasma synoviae isolates for improved epidemiology. Multilocus sequence analysis (MLSA) of 6 M. synoviae loci was conducted for genotyping of isolates with previously determined 5'-vlhA sequences. Sequencing of three polymorphic genes (5'-vlhA, cysP

Airsacculitis in Turkeys Exposed to Mycoplasma synoviae Membranes
Avian Diseases, 1987In studies to investigate the pathogenesis of mycoplasmal airsacculitis, exudative lesions were produced in turkeys by intra-air-sac inoculation with Mycoplasma synoviae cell membranes and viable organisms. Membrane inocula containing 5 mg of protein produced more severe lesions than inocula containing either 2.5 mg or 1 mg protein.

Avian Pathology, 2004
In order to study the airborne transmission of an arthropathic strain of Mycoplasma synoviae, preliminary aerosol experiments were performed. They were conducted in duplicate in an empty isolator (1.3 m3) to assess the yield and viability of M. synoviae with time compared with Mycoplasma gallisepticum and Enterococcus faecalis. After aerosol generation

The Genotyping Potential of the Mycoplasma synoviae vlhA Gene
Avian Diseases, 2012Mycoplasma synoviae (MS) continues to cause significant losses to poultry producers, and studying the epizootiology of infection is an important component of MS control. The partial variable lipoprotein hemagglutinin A (vlhA) gene is the only genomic target identified so far for MS sequence typing.

A number of experiments were carried out to study the thermal sensitivity of Mycoplasma synoviae and Mycoplasma gallisepticum as well as that of young embryos in vitro and in ovo. A full mycoplasmacidal effect was attained after heating in bouillon cultures for six hours at 45 degrees C (including cultures of Mycoplasma meleagridis), for two and a half
