BACKGROUND: Community-acquired bacterial meningitis due to Klebsiella pneumoniae has mainly been described in Southeast Asia and has a poor prognosis. Severe invasive infections caused by K. pneumoniae, including meningitis, are often due to hypervirulent strains (hvKP), which are characterized by capsular serotypes K1 and K2, a gene responsible for hypermucoviscosity, and the cluster for synthesis of the siderophore aerobactin.
CASE PRESENTATION: A 55 year old man with a history of essential hypertension, benign prostate hyperplasia, hyperlipidemia, obstructive sleep apnea, and chronic alcoholism was admitted for meningitis due to Klebsiella pneumoniae with a wild-type susceptibility profile. Its genomic features were consistent with a capsular K2 strain belonging to clonal group 86 (CG86) displaying the large virulence of Klebsiella plasmid (pLVPK) with heavy metal resistance gene clusters, aerobactin, rmpA.
CONCLUSION: This is the first case of community-acquired meningitis caused by a hypervirulent strain of hvKP ever reported in the Caribbean.https://www.ncbi.nlm.nih.gov/pubmed/27923372
