objective: mycoplasma salivarium (m. salivarium) isone of the most common contaminants present in cell culture laboratories that cause undesirable effects on cell cultures. thus, the identification and rapid diagnosis in controlling and prevention of this contaminant are important. the aim of this study is the detection of mycoplasma salivarium contamination in cell culture using polymerase cha...

BACKGROUND Mycoplasmas are the smallest free-living organisms; Mycoplasma salivarium and Mycoplasma orale are the most common species isolated from the oropharynx. Oral leukoplakia is the most prevalent potentially malignant disorder of the oral mucosa; its etiology has not been defined. Our previous study with DNA-binding fluorescent dye suggested the presence of mycoplasmas in the epithelial ...

Mycoplasma salivarium infections outside the oral cavity are rare. We describe a 49-year-old man with laryngeal cancer and right pleural space infection with M. salivarium. To our knowledge, this is the first report of empyema due to Mycoplasma salivarium.

The growth of Mycoplasma salivarium ATCC 23064 and Mycoplasma orale ATCC 15539 was inhibited by MnCl2. The growth-inhibitory effect was much more remarkable on M. orale than M. salivarium and was much more remarkable in medium supplemented with 10% (vol/vol) horse serum (HS) than 20% (vol/vol) HS. It was suggested that isolates of Mycoplasma from the oral cavity could be roughly identified as e...

Bacteria in genus Mycoplasma spp. are the smallest and simplest form of freely replicating bacteria, with 16 species known to infect humans. In the mouth, M. salivarium is the most frequently identified species. Mycoplasma spp. are parasites with small genomes. Although most of the Mycoplasma spp. that infect humans remain attached to the host cell surface throughout their life cycle, we have p...

It has been suggested that infection by some mycoplasma species can act as possible cofactors in the acceleration of immunodeficiency in HIV-infected patients. The present study was designed to examine infections by oral mycoplasma species in HIV-seropositive (HIV(+)) patients. Mycoplasma salivarium and Mycoplasma orale were isolated from 59.5% and 16.7% of 42 HIV(+) patients, respectively. Non...

Thirty-six synovial fluid samples of temporomandibular joints were obtained from 33 patients with pain and anterior disk displacement (closed lock) in the joints. DNAs were prepared from the samples and amplified by a PCR-based assay specific for Mycoplasma salivarium or Mycoplasma fermentans. Of the 36 samples, five (14%), three (8%), and 19 (53%) were positive for M. salivarium, M. fermentans...

Mycoplasma salivarium belongs to the class of the smallest self-replicating Tenericutes and is predominantly found in the oral cavity of humans. In general it is considered as a non-pathogenic commensal. However, some reports point to an association with human diseases. M. salivarium was found e.g. as causative agent of a submasseteric abscess, in necrotic dental pulp, in brain abscess and clog...

BACKGROUND Oral lichen planus (OLP) is a T-cell-mediated inflammatory disease; however, its exact etiology is unknown. Hyperkeratosis is often observed in OLP lesions. Previous studies have revealed the localization of Mycoplasma salivarium in the epithelial cells of oral leukoplakia with hyperkeratosis. Herein, we investigated the presence of M. salivarium in OLP tissue by immunohistochemistry...

Incubated mixtures of Mycoplasma salivarium and nonsensitized mixed leukocytes released histamine. Spectrophotofluorometric detection of histamine occurred at physiological temperature and pH independent of complement and specific antiserum.
