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 …

Characterization of Moraxella bovis Aspartate Transcarbamoylase
… holoenzyme architecture, and enzyme kinetics. Moraxella bovis is a fastidious organism, the etiologic agent of infectious bovine keratoconjunctivitis (IBK). The M. bovis ATCase was purified and characterized for the first time. It is a class A enzyme with a molecular mass of 480 to 520 kDa. It …

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 …

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 …

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 …

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 …

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 …

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 …

Development of an ocular drug release system for cattle
… groups of Holstein calves were infected with Moraxella bovis, the agent that causes IBK. A comparison of the ocular ring treatment with that of a field method of treatment using subconjunctival injections of Azimycin°ler demonstrated that the treatment using the ring device was significantly …

A reassessment of the epidemiology, pathogenesis and prevention strategies of bovine keratoconjunctivitis in Western Cape dairy cattle
… principal bacterial agents associated with BK, Moraxella bovis and M. bovoculi, are part of the core ocular surface microbiota in cattle. Rather than behaving as classical infectious agents, these symbionts demonstrate pathogenic potential under permissive conditions, while a range of animal- …
