Revised Mycoplasma synoviae vlhA PCRs

Avian Diseases, 2010
Mycoplasma synoviae (MS) is an important pathogen of chickens and turkeys. In recent years sequence analysis of the partial MS variable lipoprotein and hemagglutinin A (vlhA) gene PCR product has been utilized routinely for MS strain genotyping. Several PCR assays have been proposed for the amplification of the conserved upstream region of the MS vlhA ...

Serological Studies with Mycoplasma synoviae

Avian Diseases, 1967
One of the agents responsible for the clinical syndrome in chickens known as infectious synovitis has been designated Mycoplasma synoviae (14). It is represented in this study by strain WVU 1853. Various papers have indicated antigenic relationship between M. synoviae and M. gallisepticum. Pooled serum samples from chickens infected with M.

Field Studies with Mycoplasma synoviae

Avian Diseases, 1973
SUMMARY Mycoplasma synoviae infections have been shown to affect broiler performance as determined by reduced body weight, poorer feed conversion, increased condemnations for airsacculitis and septicemia-toxemia, as well as increased cost of pounds of broilers produced by an integrated broiler-producing operation.

Factors Influencing Growth of Mycoplasma synoviae

Avian Diseases, 1974
Ten isolates of Mycoplasma synoviae (MS) from air sacs and joints of chickens were propagated in a medium enriched with diphosphopyridine nucleotide (NAD), cysteine, and glucose. Yields of antigen were 1.4 to 3.3% of the total medium. Three antigens did not agglutinate with all heterologous antisera.

Lyophilization of Mycoplasma synoviae Hemagglutination Antigen

Avian Diseases, 1987
Two hemagglutination (HA) antigens produced from Mycoplasma synoviae isolates WVU-1853m and FMT grown in Frey's mycoplasma broth were lyophilized for HA preservation. Some increase in the HA titer occurred following lyophilization.

Recombinant DNA Probes for Mycoplasma synoviae

Avian Diseases, 1990
A genomic library was prepared from Mycoplasma synoviae (MS) strain WVU 1853 cloned in plasmid vector pUC8 and transformed in Escherichia coli host JM83. In dot blot assays, four transformed E. coli clones hybridized with 32P-labeled chromosomal DNA of MS but not with 32P-labeled chromosomal DNA of M. gallisepticum (MG) strain S6.

Immunoglobulin G Fc Receptors of Mycoplasma synoviae

Avian Diseases, 1991
The objective of the study was to demonstrate and characterize IgG Fc receptors of Mycoplasma synoviae. Two IgG Fc receptors were recognized with molecular weights (MW) of 80,000 and 90,000 and isoelectric focusing points (pI) of 5.3 and 4.3, respectively.

Strain of Mycoplasma synoviae of Low Transmissibility

Avian Diseases, 1983
An infection with Mycoplasma synoviae that spread slowly within and among pens of chickens was observed in a brown-egg breeding population that had long been free of M. gallisepticum and M. synoviae. There were unusually long periods of time between the first serological evidence of infection in a pen of chickens and the time that most of the group ...

Experimental Infection of Ducks with Mycoplasma synoviae

Avian Diseases, 1983
Specific-pathogen-free ducks 24 and 180 days old were inoculated intranasally with the WVU 1853 strain of Mycoplasma synoviae (MS). No significant gross lesions were found in the infraorbital sinus, trachea, or air sacs at 7 or 28 days postinfection (PI), although MS was recovered from all these organs. A few ducks responded serologically by developing

Haemagglutination and haemagglutination inhibition with Mycoplasma synoviae

Research in Veterinary Science, 1975
A haemagglutinating antigen prepared from cultures of M synoviae WVU 1853 successfully detected homologous haemagglutination inhibition (HI) in sera of fowls and turkeys inoculated with M synoviae. Nonspecific HI was encountered with normal fowl sera but this was removed by treatment with receptor destroying enzyme. It is suggested that M synoviae.
