The in vitro activity of a new orally administered carbacephem analog of cefaclor, loracarbef (LY163892), was compared with those of cefaclor and several other oral antimicrobial agents against recent clinical isolates of Haemophilus influenzae and Moraxella catarrhalis. Loracarbef was found to be slightly more active than cefaclor against H. influenzae and had activity essentially equivalent t...
Slevogt, Hortense, Bernd Schmeck, Carola Jonatat, Janine Zahlten, Wiebke Beermann, Vincent van Laak, Bastian Opitz, Solveig Dietel, Philippe Dje N’Guessan, Stefan Hippenstiel, Norbert Suttorp, and Joachim Seybold. Moraxella catarrhalis induces inflammatory response of bronchial epithelial cells via MAPK and NFB activation and histone deacetylase activity reduction. Am J Physiol Lung Cell Mol Ph...
Moraxella catarrhalis, a major nasopharyngeal pathogen of the human respiratory tract, is exposed to rapid and prolonged downshifts of environmental temperature when humans breathe cold air. In the present study, we show that a 26 degrees C cold shock up-regulates the expression of UspA1, a major adhesin and putative virulence factor of M. catarrhalis, by prolonging messenger RNA half-life. Col...
The complement system is an important part of the innate defense against invading pathogens (Blom et al., 2009; [1]). The ability to resist complement-mediated killing is considered to be an important virulence trait for the human-restricted respiratory tract pathogen Moraxella catarrhalis, as most disease-associated M. catarrhalis isolates are complement-resistant (Wirth et al., 2007; [2]). He...
4. Verhaegh SJ, Snippe ML, Levy F, Verbrugh HA, Jaddoe VW, Hofman A, et al. Colonization of healthy children by Moraxella catarrhalis is characterized by genotype heterogeneity, virulence gene diversity and co-colonization with Haemophilus infl uenzae. Microbiology. 2011;157:169–78. http://dx.doi.org/10. 1099/mic.0.042929-0 5. Sturm AW, Mostert R, Rouing PJ, van Klingeren B, van Alphen L. Outbr...
OBJECTIVES The aim of this study was to detect the presence of IgG against Moraxella catarrhalis β-lactamase in healthy adults, and to determine whether outer membrane vesicles (OMVs) could protect the enzyme from inhibition by anti-β-lactamase IgG. METHODS Transmission electron microscopy was used to detect the presence of β-lactamase in OMVs. Sera were examined by ELISA for specific IgG dir...
