Background: Moraxella catarrhalis is Gram negative diplococci which is a member of Neisseriacae. It was considered as a harmless commensal of the upper respiratory tract. Since 1990 its pathogenecity was established and known as a common cause of respiratory infection, particularly otitis media, sinusitis and lower respiratory tract. The aim of this research was to determine the prevalence and ...

In a study lasting over two years the frequency and sensitivity of moraxella catarrhalis causing respiratory tract infections were studied. Sputum samples from patients with lower respiratory tract infections were screened for moraxella catarrhalis. The organisms isolated identified and their sensitivity determined by simple methods which are practicable. The study shows that 22.4% of the infec...

Respiratory tract infections are considerably prevalent worldwide and identifying their aetiological agents is of great medical and therapeutic value. The aims of the present study are to determine the prevalence of Moraxella catarrhalis among Sudanese patients infected with respiratory tract infections (upper and lower) and to determine the antibiotic sensitivity pattern of Moraxella catarrhal...

The bloodstream is sterile under normal conditions. Transient bacteremia occurs when bacteria enter the bloodstream. Bacterial species; general health care of the patient; and type of dental procedures are effective on the emergence of bacteremia complications. Moraxella catarrhalis is an exclusively human commensal of the upper respiratory tract and oral cavity. As Moraxella catarrhalis has be...

Moraxella catarrhalis has gained reputation as a pathogen in the lower respiratory tract especially in patients with underlying chronic lung diseases. It is considered significant when isolated from sputum specimens of adults with respiratory tract infections. A study was carried out to determine the prevalence of Moraxella catarrhalis isolated in sputum specimens and beta-lactamase production ...

Moraxella (formerly Branhamella) catarrhalis was discovered at the end of the nineteenth century, and for many decades it was considered to be a harmless commensal of the upper respiratory tract. It is a Gram-negative, aerobic diplococcus considered to be the third most common pathogen isolated in childhood sinusitis and otitis media and in adult chronic lower respiratory disease, as well as an...

Moraxella catarrhalis is a major cause of infectious exacerbations of chronic obstructive lung disease. In pulmonary epithelial cells, M. catarrhalis induces release of the pro-inflammatory cytokine interleukin (IL)-8, which plays a pivotal role in orchestrating airway inflammation. The present study demonstrated that protein kinase (PK)C was activated by Moraxella infection and positively regu...

background neisseria lactamica as one of the main commensal in oropharynx during the childhood is related to the induction of a natural immunity against meningococcal meningitis. also moraxella catarrhalis in oropharynx of children is a predisposing factor for otitis media infection. objectives the current study aimed to investigate the frequency of the n. lactamica, other nonpathogenic neisser...

Barbe and coworkers tested 318 isolates of Haemophilus and Neisseria species as well as Moraxella catarrhalis in an evaluation of the API NH kit in a study primarily addressing the ability of that kit to accurately identify organisms in its intended area of application (1). They found that only 1 of the 305 strains that were included in the kit database was identified incorrectly, and of the 13...
