A fatal endocarditis case due to an emerging bacterium: Moraxella nonliquefaciens

Meningitis due to Moraxella nonliquefaciens in a paediatric patient: a case report and review of the literature

Introduction.Moraxella nonliquefaciens is an unusual organism to be isolated from cerebral spinal fluid (CSF) and there exists only one case report of M. nonliquefaciens meningitis from a neonate. Moraxella species normally exist as part of the human upper respiratory tract flora and rarely cause invasive human disease. There are only a handful of case reports implicating the organism as a caus...

Reciprocal Genetic Transformation between Neisseria Catarrhalis and Moraxella Nonliquefaciens.

Association of mucoid encapsulated Moraxella duplex var. nonliquefaciens with chronic bronchitis.

The recovery of two strains of highly mucoid encapsulated Moraxella duplex var. nonliquefaciens from the sputum of two patients suffering from chronic bronchitis is described. The biochemical, morphological, and pathogenic characteristics of this microorganism are discussed.

Selective medium for Moraxella nonliquefaciens.

A medium is described which selectively inhibits most bacteria from the normal flora of the conjunctiva, the lid-margin, and the upper respiratory tract but permits growth of Moraxella nonliquefaciens, M. liquefaciens, and the less fastidious strains of M. lacunata. The selective conditions are obtained with thiostrepton, tyrothricin, and sodium nalidixinate as inhibitors. Incubation under incr...

Profiling bacterial community in upper respiratory tracts

BACKGROUND Infection by pathogenic viruses results in rapid epithelial damage and significantly impacts on the condition of the upper respiratory tract, thus the effects of viral infection may induce changes in microbiota. Thus, we aimed to define the healthy microbiota and the viral pathogen-affected microbiota in the upper respiratory tract. In addition, any association between the type of vi...
