The goal of the current study was to evaluate the prevalence of Mycoplasma organisms in the BAL fluid of paediatric patients suffering from a variety of chronic respiratory diseases to determine if there was any clear disease association with bacterial presence.

METHODS: We examined 319 paediatric BAL samples for the presence of M.genitalium, M.hominis, U.urealyticum, U.parvum and M.pneumoniae DNA with species-specific PCR.

RESULTS: Mycoplasma DNA was found in 32.6% (104/319) of patient samples; 10% (32/319) for M.pneumoniae, 8.8% for U.parvum, 2.8% for U.urealyticum; 4.7% for M.hominis and 9.1% for M.genitalium. There were no significant clinical and laboratory differences except serum IgE in asthmatics according to Mycoplasma colonization or not. Elevated levels of IgE were found more often in Mycoplasma DNA-negative patients than patients with bacterial DNA, 85/109 versus 24/109 respectively (P&lt;0.0001). There was no difference in the frequency of Mycoplasmas between the asthmatics and the non-asthmatics; 30.6% (69/225) versus 37.2% (35/94) for Mycoplasma 16S DNA, and 8% versus 14.9% for M.pneumoniae, respectively.

CONCLUSIONS: Our data indicate that in addition to M.pneumoniae, urogenital Mycoplasma species may colonize the airway of patients with chronic respiratory diseases. There was, however, no association between chronic asthma diagnosis and Mycoplasma colonization in this study.</style></abstract><issue><style face="normal" font="default" size="100%">7</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/21722263?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Stuart, Elizabeth S</style></author><author><style face="normal" font="default" size="100%">Webley, Wilmore C</style></author><author><style face="normal" font="default" size="100%">Norkin, Leonard C</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Lipid rafts, caveolae, caveolin-1, and entry by Chlamydiae into host cells.</style></title><secondary-title><style face="normal" font="default" size="100%">Exp Cell Res</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Exp.

C. trachomatis serovar K recently was shown to enter cells via caveolae-like lipid raft domains. We asked here how widespread raft-mediated entry might be among the Chlamydia. We show that C. pneumoniae, an important cause of respiratory infections in humans that additionally is associated with cardiovascular disease, and C. psittaci, an important pathogen in domestic mammals and birds that also infects humans, each enter host cells via cholesterol-rich lipid raft microdomains. Further, we show that C. trachomatis serovars E and F also use these domains to enter host cells. The involvement of these membrane domains in the entry of these organisms was indicated by the sensitivity of their entry to the raft-disrupting agents Nystatin and filipin, and by their intracellular association with caveolin-1, a 22-kDa protein associated with the formation of caveolae in rafts. In contrast, caveolin-marked lipid raft domains do not mediate entry of C. trachomatis serovars A, 36B, and C, nor of LGV serovar L2 and MoPn. Finally, we show that entry of each of these chlamydial strains is independent of cellular expression of caveolin-1. Thus, entry via the Nystatin and filipin-sensitive pathway is dependent on lipid rafts containing cholesterol, rather than invaginated caveolae per se.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/12799183?dopt=Abstract</style></custom1></record></records></xml>
