Transcription in Mycoplasma pneumoniae
Das humanpathogene Bakterium Mycoplasma pneumoniae besitzt lediglich ein kleines Repertoire von Genen, die vermutlich an der Transkriptionsregulation beteiligt sind. Dieser Umstand reflektiert seine Anpassung an ein nährstoffreiches Habitat mit konstanten Umweltbedingungen, dem menschlichen …

Regulation of HPr phosphorylation in Mycoplasma pneumoniae
Das Genom des Mollicuten Mycoplasma pneumoniae enthält lediglich 688 Gene. Zu den wenigen erhalten gebliebenen Proteinen mit regulatorischer Funktion gehört die HPr-Kinase/Phosphorylase (HPrK/P) aus dem Phosphoenolpyruvat:Zucker-Phosphotransferase-System. In dieser Arbeit wurde das in vivo …

Glycerolmetabolismus und Pathogenität von <i>Mycoplasma pneumoniae</i>
Mycoplasma pneumoniae, der Erreger der atypischen Pneumonie, kann neben Glukose und Fruktose auch Glycerol als Kohlenstoffquelle nutzen. Das Glycerol wird über erleichterte Diffusion in die Zelle geschleust und anschließend durch die Glycerol-Kinase phosphoryliert. Das Glycerol-3-phosphat wird dann …

Untersuchungen von Cytoskelett-Komponenten und Motilität bei Mycoplasma pneumoniae
Die Zellstruktur des Bakteriums Mycoplasma pneumoniae wurde durch elektronenmikroskopische und lichtmikroskopische Methoden untersucht. Ultrastrukturelle Details des Cytoskeletts von M. pneumoniae wurden mittels verschiedener Präparationstechniken abgebildet. Ein im Tip der Zelle lokalisiertes …

Mycoplasma Pneumoniae Infections - Role of Nucleotide Metabolism in the Mechanism of Pathogenesis
The method by which Mycoplasma pneumoniae induces a cytopathic effect (CPE) in host cells is not clearly defined. This study was designed to delineate some of the factors involved in the mechanism of pathogenesis of M. pneumoniae infection. Two major areas affecting the host-parasite interaction …

Analysis of protein-protein interactions linked to the formation of a bacterial cytoskeleton in Mycoplasma pneumoniae
Mycoplasma pneumoniae has a cytoskeleton-like structure. Based on genetic evidence, it was proposed that the 1818 amino acids long protein HMW2 plays a central role in both formation of the cytoskeleton-like structure and adherence to its host cell (cytadherence). As gene products of the hmw2 gene …

The prevalence of Legionella and mycoplasma seropositivity in the elderly in Cape Town
… an appropriate agent has been delayed. Whereas Mycoplasma pneumoniae and Legionella pneumophila are sensitive to the macrolides or tetracycline, they do not respond to the currently recommended first-line agents for community acquired pneumonia, penicillin or a cephalosporin. It was therefore …

The spectrum of acute and subacute myelopathy
… virus infections and 1 had an infection with Mycoplasma pneumoniae. Two had systemic lupus erythematosus and 1 had an acute cord infarct following an aortic aneurysm repair. The literature is reviewed and the findings of this study correlated with previous ones. Conclusions regarding …

Regulation of Adaptive Immunity in the Lung by the Alveolar Epithelial Type II Cell and Surfactant Protein a
… cells. Using a model of pulmonary infection with Mycoplasma pneumoniae, wildtype mice were found to have fewer mature dendritic cells in the mediastinal lymph nodes than SP-A null mice. The presence of SP-A in the wild-type mice had a suppressive effect on the M. pneumoniae-induced maturation of …

The effect of human cytomegalovirus on neutrophil survival, autophagy, and extracellular traps
… clean HCMV after the discovery of contaminating Mycoplasma spp. in the viral inocula of the initial experiments. Mycoplasma-HCMV coinfection induced an autophagic phenotype in neutrophils, as assessed by Western blotting and qPCR of autophagy-related components. Inhibition of autophagy using 3-MA …

Identification of potential pathogens of pneumonia in sputum samples from adult patients at the University Teaching Hospital in Lusaka
… aeruginosa 19.9% (45/226), and Klebsiella pneumoniae 14.2% (32/226). Almost all (10/11) K. pneumoniae isolates were multidrug resistant (7 of 9 drugs) and were ESBL positive. About 71% of the 146 samples tested using PCR yielded human cytomegalovirus 24.3% (44/181), K. pneumoniae 17.7% …
