Upper respiratory infection due to Neisseria meningitidis

An upper respiratory infection due to *Neisseria meningitidis* is a localized bacterial infection of the nasopharynx or upper respiratory tract caused by the Gram-negative diplococcus *Neisseria meningitidis*

An upper respiratory infection due to *Neisseria meningitidis* is a localized bacterial infection of the nasopharynx or upper respiratory tract caused by the Gram-negative diplococcus *Neisseria meningitidis* Although the organism frequently exists as a commensal colonizer of the human nasopharyngeal mucosa, it can cause symptomatic mucosal inflammation characterized by pharyngitis, sore throat, fever, and purulent rhinitis, often serving as a prodrome in susceptible populations such as infants,...

Pathophysiologically, the bacteria adhere to and invade nonciliated nasopharyngeal epithelial cells, eliciting a local inflammatory response that risks breach of the mucosal barrier and subsequent hematogenous dissemination to cause invasive meningococcal disease, including septicemia and meningitis
