Non-gonococcal non-meningococcal Neisseria sp. normally inhabits the upper respiratory tract in human beings. There are four recognized species within the genus: N. sicca, N. mucosa, N. subflava and N. flavescens. They have low pathogenicity. Among them, Neisseria mucosa and N. sicca have been described to cause endocarditis. To our knowledge, this is the fourth reported case of prosthetic valv...

Phylogenies generated from whole genome sequence (WGS) data provide definitive means of bacterial isolate characterization for typing and taxonomy. The species status of strains recently defined with conventional taxonomic approaches as representing Neisseria oralis was examined by the analysis of sequences derived from WGS data, specifically: (i) 53 Neisseria ribosomal protein subunit (rps) ge...

Peritonitis is a leading complication of chronic ambulatory peritoneal dialysis. However, very rarely does Neisseria mucosa cause peritonitis. We describe an unusual case of N. mucosa peritonitis in a chronic ambulatory peritoneal dialysis patient. A 28-year-old Hispanic male presents with diffuse abdominal pain exacerbated during draining of the peritoneal fluid. Peritoneal fluid examination w...

Antibiotic-sparing treatments are required to prevent the further emergence of antimicrobial resistance in Neisseria gonorrhoeae. Commensal species have previously been found inhibit growth pathogenic species. For example, a previous study that three out five historical isolates mucosa could N. In this study, we used agar overlay assays assess if 24 circulating and 28 Although pitting around ea...

GeneXpert CT/NG was evaluated with 372 characterized bacterial strains. Sensitivity of 10 genome copies/reaction was obtained for both agents. Four Neisseria mucosa and two Neisseria subflava isolates were positive for one of two gonococcal targets; however, the assay flagged all as negative. The assay was analytically highly sensitive and specific.

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...
