چکیده

Mycoplasma contamination is a frequent problem in chlamydial cell culture. After obtaining contradictory contamination results, we compared three commercial PCR kits for mycoplasma detection. One kit signaled contamination in mycoplasma-free Chlamydia pneumoniae cultures. Sequencing of cloned PCR products revealed primer homology with the chlamydial genome as the basis of this false-positive result.

Isolation and detection of Mycoplasma pneumoniae from cell culture by culture and PCR.

Background: Mycoplasma pneumoniae is one of the major species of mycoplasmas which could contaminate cell cultures. Identification of M. pneuminae is significant because Mycoplasmas could contaminate and have unsuitable effect on the cell cultures. Rapid detection of these contaminations is so important and it could be significant role in preventing and controlling of contamination in cell cul...

Detection of mycoplasma contamination in cell cultures by a mycoplasma group-specific PCR.

The suitability of a 16S rRNA-based mycoplasma group-specific PCR for the detection of mycoplasma contamination in cell cultures was investigated. A total of 104 cell cultures were tested by using microbiological culture, DNA fluorochrome staining, DNA-rRNA hybridization, and PCR techniques. A comparison of the results obtained with these techniques revealed agreement for 95 cell cultures. Disc...

Mycoplasma fermentans, M. hominis, and M. hyorhinis inhibit infectivity and growth of Chlamydia trachomatis and C. pneumoniae in HEp-2 cells.

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...

Investigation of Mycoplasma agalactiae in sheep in Kurdistan province by PCR

Contagious agalactia (CA) is a serious disease syndrome of sheep and goats that is characterized by mastitis, arthritis, keratoconjunctivitis and, occasionally, abortion. Mycoplasma (M.) agalactiae is the main cause of the disease in sheep and goats. The aim of the present study was to detect M. agalactiae in conjunctival, synovial fluid, nasal, ear and milk samples in sheep herds with or witho...
