Restriction Endonuclease Analysis of Mycoplasma synoviae Strains

Avian Diseases, 1990
A diverse group of Mycoplasma synoviae strains from various hosts, pathological processes, and geographic areas collected over about 25 years were analyzed by restriction endonuclease analysis. The results suggest that restriction endonuclease analysis of M. synoviae strains may be a useful strain identification tool to study epidemiological problems.

Pathogenicity of Mycoplasma synoviae in Chicken Embryos

Avian Diseases, 1999
Pathogenicity of Mycoplasma synoviae (MS) was examined in specific-pathogen-free (SPF) white leghorn chicken embryos. Six isolates of MS were inoculated into 7-day embryos via the yolk sac. Isolates were evaluated for gross and microscopic lesions through 19 days' incubation and for embryo lethality through 20 days' incubation.

Factors Associated with Virulence of Mycoplasma synoviae

Avian Diseases, 1999
Virulence mechanisms of six isolates of Mycoplasma synoviae (MS), previously classified as pathogenic (K1968), moderately pathogenic (WVU 1853, K1858, 92D8034, and F10-2AS), and mildly pathogenic (FMT) in chickens, were examined. The most virulent isolate, K1968, had been found to invade systematically and produce lesions following eye-drop inoculation.

Genetic and antigenic relatedness between Mycoplasma gallisepticum and Mycoplasma synoviae

Veterinary Microbiology, 1989
The two avian pathogens Mycoplasma gallisepticum and Mycoplasma synoviae were found, by Southern blot hybridization of their digested DNAs, to share genomic nucleotide sequences additional to those of the highly conserved ribosomal RNA genes. The assumption that some of the shared sequences encode for antigens or epitopes common to both mycoplasmas was

Turkey Sinusitis: Synergism between Mycoplasma synoviae and Mycoplasma meleagridis

Avian Diseases, 1977
Sinusitis was produced experimentally in turkeys after intrasinus inoculation with broth cultures of both Mycoplasma synoviae and Mycoplasma meleagridis. No evidence of sinusitis was observed in other turkeys exposed to each of these organisms separately- indicating pathogenic synergism with these mycoplasmas.

Mycoplasma synoviae cell invasion: Elucidation of the Mycoplasma pathogenesis in chicken

Comparative Immunology, Microbiology and Infectious Diseases, 2011
Fluorochrome-labelled cells of two field isolates and Mycoplasma synoviae (Ms) were inoculated onto monolayer cultures of fluorochrome-labelled HEp-2 cells and monitored by confocal laser scanning microscopy (CLSM). Ms was detected initially adhered to and subsequently inside the host cells.

Comparison ofMycoplasma synoviaeisolates by immunoblotting

Avian Pathology, 1992
SDS-polyacrylamide gel electrophoresis (PAGE) and immunoblot profiles using antisera from M. synoviae F10-2AS-inoculated chickens detected heterogeneity among 10 M. synoviae isolates. This variation was primarily seen in immunoblots as a difference in the molecular size of immunoreactive proteins below 50 kDa and corresponded to an area of variability ...

Molecular Typing of Indian Mycoplasma synoviae Isolates

Indian Journal of Animal Research, 2020
Background: Mycoplasma synoviae is an economically significant pathogen in poultry with reported increased prevalence and virulence in recent years. The pathogen causes subclinical upper respiratory tract infection, air sacculitis and infectious synovitis. Methods: This study aimed to characterize the field isolates of M.

Serological Detection of Mycoplasma synoviae Infection in Turkeys

Avian Diseases, 1992
The antibody response of turkeys experimentally infected with Mycoplasma synoviae was determined by the serum plate agglutination (SPA), hemagglutination-inhibition (HI), and microagglutination (MA) tests and the enzyme-linked immunosorbent assay (ELISA). No antibody response was detected until 2 weeks postinfection (PI) with the MA test (17% positive),
