Mycoplasma contaminants can be considered important not only for their roles as pathogens but also they may indicate that insufficient care has been taken during vaccine manufacture or quality control. The purpose of this study was to test the poliomyelitis vaccines for Mycoplasma by culture and polymerase chain reaction (PCR) methods. During 2008 to 2009, a total of 47 lots of oral poliomyelit...

The maintenance of contamination-free cell lines is essential to cell-based research. Among the biggest contaminant concerns are mycoplasma contamination. Although mycoplasma do not usually kill contaminated cells, they are difficult to detect and can cause a variety of effects on cultured cells, including altered metabolism, slowed proliferation and chromosomal aberrations. In short, mycoplasm...

mycoplasma is an important respiratory tract pathogen worldwide, causing respiratory tract infection in small ruminants ( sheep and goats). it is a bacterium that causes acute respiratory illness ranging in severity from mild respiratory illness to severe pneumonia. mycoplasmosis in small ruminants is a serious and major problem in iran. this study was determined to isolate mycoplasma species a...

background: mycoplasma hominis and ureaplasma urealyticum microorganisms may play a role in infertility. the aim of this study is to determine prevalence of mycoplasma hominis and ureaplasma urealyticum microorganisms in infertile women and their husbands. methods: in this cross-sectional study presence of mycoplasma hominis and ureaplasma urealyticum were examined in infertile couples who have...

Objective. In connection with the possible relationship between Mycoplasma infection and the onset of asthma, several studies have shown not only a high level of serum total immunoglobulin E (IgE) but also the production of IgE specific to Mycoplasma or common allergens during the course of Mycoplasma infection. It has been suggested that the balance of T helper type 1 (TH1)/T helper type 2 (TH...

haemoplasmas contain eperythrozoon and haemobartonella species, which are widespread causes of animal and human infections. these obligatory cell parasites were previously known as hemobartonella; now hemotropic mycoplasmas. these bacteria are identified by the lack of cell wall and their small genome. the usual diameter is between 0.3 and1μm. mycoplasmasarepolymorphic and seen in circular or b...

Peptide deformylase inhibitor LBM-415 and seven other drugs were tested against Mycoplasma pneumoniae (100 isolates), Mycoplasma hominis (20 isolates), Mycoplasma fermentans (10 isolates), and Ureaplasma species (50 isolates). LBM-415 was active against M. pneumoniae (MICs, <or=0.008 microg/ml). It showed no activity against M. hominis and M. fermentans and modest activity against Ureaplasma spp.

Mycoplasma pneumoniae infection usually presents with upper and lower respiratory tract infection. Extrapulmonary involvement is not uncommon, however. We report two cases of predominantly extrapulmonary manifestations of Mycoplasma pneumoniae infection without significant pulmonary involvement. Both cases were diagnosed by serology. These cases illustrate the diversity of clinical presentation...

A lymphocyte blastogenesis inhibitory factor, (LBIF), was purified from the culture supernatant of human histiocytic lymphoma U937 by fast protein liquid chromatography. In this study, we demonstrated, first, that LBIF originated from a mycoplasma, Mycoplasma arginini, infecting U937 cells, and second, that LBIF bore the arginine deiminase activity. The implication of in vivo immunosuppression ...

We determined in vitro susceptibilities for ABT-492 and other antimicrobials against Mycoplasma pneumoniae, Mycoplasma fermentans, Mycoplasma hominis, and Ureaplasma species. ABT-492 MICs were < or =1 microg/ml, and the agent was bactericidal against selected isolates of M. pneumoniae and M. hominis. ABT-492 has potential for treatment of infections due to these microorganisms.
