Biofilm Formation by Moraxella Catarrhalis
… in vitro by the Gram-negative bacterial pathogen Moraxella catarrhalis. Growth of M. catarrhalis in a continuous-culture biofilm system resulted in little detectable change in outer membrane protein production compared to broth-grown M. catarrhalis. Biofilm-grown M. catarrhalis may produce an …

HAEMOPHILUS INFLUENZAE AND MORAXELLA CATARRHALIS INTRA- AND INTERSPECIES QUORUM SIGNALING
… influenzae</italic> and <italic>Moraxella catarrhalis</italic> are more frequently found to coexist than to be isolated individually. Polymicrobial infection and biofilm formation may have a dramatic impact on the severity and treatability of OM. Thus, there is a pressing need to …

The role of Moraxella catarrhalis outer membrane proteins in pathogenesis
Moraxella catarrhalis is an important respiratory pathogen. It is a common cause of otitis media in children, a usual infections agent in sinusitis and makes up to 10% of all exacerbations of chronic obstructive pulmonary disease (COPD). It is known to cause more frequent disease in the colder …

Interactions between Streptococcus pneumoniae and Moraxella catarrhalis in polymicrobial communities affect antimicrobial resistance and survival in vivo
… pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. The initial step in the development of otitis media is nasopharyngeal colonization. The next step involves ascension through the Eustachian tube to access the middle ear space. For persistance within their host, it has been …

Antibiotic Resistance: Multi-Drug Profiles and Genetic Determinants.
… profiles were assembled for isolates of <em>Moraxella catarrhalis</em> collected from the Mountain Home Veteran's Affairs Medical Center (VAMC) clinical laboratory in Johnson City, Tennessee. The goal of the study was to identify isolates for genetic characterization using comparisons of …

Assessing the Effect of “Time of Birth” on Nasopharyngeal Microbial Load in Infants
… microbial load of the most abundant otopathogen, Moraxella Catarrhalis. This is a retrospective analysis of data collected between 2009 – 2014 as part of a longitudinal study to determine risk factors for AOM. Subjects were recruited near birth and followed up to 1 year of age. For measurement of …

Bacterial Outer Membrane Vesicles. Mediators of virulence and antibiotic resistance.
… involved in pathogenesis and bacterial survival. Moraxella catarrhalis and Haemophilus influenzae are Gram-negative bacterial species that cause respiratory tract infections such as acute otitis media and exacerbations in chronic obstructive pulmonary disease (COPD). The aim of this thesis was to …

Electrochemical Studies and Antimicrobial Properties of Synthesized Green Mediated Metal Oxide Nanoparticles
… Enterococcus faecium, Escherichia coli, Moraxella catarrhalis, Aeromonas hydrophilia, and Listeria monocytogenes used in the analysis. Iron oxide nanoparticles also showed activity against the pathogenic strains with the exception of Klebsiella pneumoniae in the case of iron oxide …

Identification of potential pathogens of pneumonia in sputum samples from adult patients at the University Teaching Hospital in Lusaka
… probable pathogens with the most common being Moraxella catarrhalis 20.8% (47/226), Pseudomonas 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 …

THE EFFECT OF INDOOR TOTAL SUSPENDED PARTICLES (TSP) ON THE HUMAN UPPER RESPIRATORY SYSTEM: FROM THE MICROBIOME TO HERV METHYLATION
… samples. The winter samples were enriched in Moraxella species (Moraxella catarrhalis and Moraxella nonliquefaciens) and the diversity was lower. The microbiome of the anterior nares was similar in taxa composition to the nasopharynx microbiome. They were both mostly dominated by gram-positive …

Purification of Aspartate Transcarbamoylase from Moraxella (Branhamella) catarrhalis
… aspartate transcarbamoylase (ATCase) from Moraxella (Branhamella) catarrhalis, has been purified. The holoenzyme has a molecular mass of approximately 510kDa, harbors predominantly positive charges and is hydrophobic in nature. The holoenzyme possesses two subunits, a smaller one of 40 kDa …
