Mycoplasma synoviae (M. synoviae) is a major worldwide poultry pathogen that causes serious economic losses in the poultry industry. This study was designed to detect M. synoviae through culture isolation and polymerase chain reaction (PCR) assay to demonstrated the involvement of M. synoviae infection in trachea and the lung/air sac samples taken from commercial broiler chicken farms in 3 m...

BACKGROUND Infections with the three feline haemotropic mycoplasmas Mycoplasma haemofelis, Candidatus Mycoplasma haemominutum and Candidatus Mycoplasma turicensis cause feline infectious anemia. The purpose of this study was to investigate the prevalence of carriage of feline haemoplasma in Danish cats in different age groups. The presence was detected by a conventional polymerase chain reactio...

We read with great interest the data reported by Castilla and Wadowsky about the elimination of a Mycoplasma hominis-like mycoplasma from the TW-183 strain of Chlamydia pneumoniae and its lack of effect on chlamydial infection of HEp-2 cells (1). We recently described detection of Mycoplasma fermentans, M. hominis, and M. hyorhinis in several strains of C. trachomatis and C. pneumoniae, the suc...

Since Mycoplasma hyopneumoniae isolation in appropriate media is a difficult task and impractical for daily routine diagnostics, Nested-PCR (N-PCR) techniques are currently used to improve the direct diagnostic sensitivity of Swine Enzootic Pneumonia. In a first experiment, this paper describes a N-PCR technique optimization based on three variables: different sampling sites, sample transport m...

BACKGROUND AND OBJECTIVES Mycoplasma arthritidis mitogen (MAM) superantigen has been shown to induce chronic arthritis, which resembles human rheumatoid arthritis (RA) in a rodent model. However, its role as a causative agent in human RA is not well understood yet. The aim of this study was to investigate the presence of MAM superantigen gene in the synovial fluid (SF) of RA patients. MATERIA...

BACKGROUND Intra-amniotic infection has long been recognized as the leading cause of preterm delivery. Microbial culture is the gold standard for the detection of intra-amniotic infection, but several days are required, and many bacterial species in the amniotic fluid are difficult to cultivate. METHODS We developed a novel nested-PCR-based assay for detecting Mycoplasma, Ureaplasma, other ba...

PCR primers corresponding to the adhesin genes of Mycoplasma pneumoniae and Mycoplasma genitalium were shown to detect the corresponding organisms specifically. Absence of cross-reaction with seven other mollicute species and six unrelated bacterial species commonly found in humans was demonstrated. Positive control primers directed against human mitochondrial DNA could be mixed with the Mycopl...

The current study described the isolation and molecular detection of Mycoplasma gallisepticum (Mg) and Mycoplasma synoviae from tracheal swabs of diseased birds showing signs of respiratory distress in selected commercial (layer and broiler) farms and from yolk and an open air of pens of vaccinated breeder flocks in Sudan. A number of 45 Mycoplasma isolates were recovered from chickens in Khart...

BACKGROUND: Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) are the most important and pathogenic mycoplasma in chicken production. The tendency of avian mycoplasma for interaction with other pathogen is well-known. Interaction within several disease-producing factors in respiratory tract exacerbate the disease and known as multicausal respiratory disease. OBJECTIVES: In recent years...

Background: Mycoplasma is one of the most important pathogens of respiratory system in poultry. OBJECTIVES: The aim of the present study was to identify Mycoplasma spp. isolated from pigeons. METHODS: Sixteen pooled samples were provided and cultured on PPLO medium and finally the DNA was extracted from the resulting single colonies. RESULTS: Through 16S rRNA gene amplification Mycoplasma genus...
