Escherichia coli isolates of serotype O18:K1:H7, taken from women with acute cystitis, healthy control patients, and infants with neonatal bacterial meningitis (NBM), were analyzed and were compared with phylogenetically diverse control strains from the E. coli Reference collection. Clonal relationships were defined by amplification phylotyping, nicotinamide auxotrophy, and outer membrane protein patterns (OMPs). Virulence factor profiles were determined by multiplex polymerase chain reaction, probe hybridization, and hemagglutination testing. The O18:K1:H7 cystitis, fecal, and NBM isolates were clonally derived. The cystitis isolates and archetypal NBM isolates RS218 and C5 were from the OMP6 subclone of E. coli O18:K1:H7 and exhibited a consensus virulence genotype that included papG allele III (cystitis-associated P fimbrial adhesin), sfaS (S fimbrial adhesin), hlyA (hemolysin), cnf1 (cytotoxic necrotizing factor), iroN (putative siderophore), and ibeA (invasion of brain endothelium). The demonstrated commonality between O18:K1:H7 isolates from cystitis and NBM suggests common pathogenetic mechanisms and the possibility of new approaches to prevention.

Escherichia coli NU14, a cystitis isolate used to study the pathogenesis of cystitis and to develop a FimH (type 1 fimbrial adhesin) vaccine, was assessed for extended virulence genotype, phylogenetic background, and FimH sequence and binding phenotype(s). NU14 exhibited the same virulence genotype and was derived from the same (meningitis- and cystitis-associated) subclone of E. coli O18:K1:H7 as the archetypal neonatal bacterial meningitis (NBM) isolate RS218. NU14 also displayed the same Ser62Ala FimH polymorphism as did NBM isolates RS218 and IHE3034-conferring both collagen binding and a distinct monomannose binding capability (which characterizes uropathogenic but not commensal E. coli and dramatically increases adherence to uroepithelial cells). These findings establish that strain NU14 exhibits numerous urovirulence-associated traits and derives from the single most prevalent clonal group in acute cystitis. They provide further evidence of clonal and pathotypic similarities between cystitis and NBM isolates of E. coli O18:K1:H7.

A combination of acute urinary retention and aseptic meningitis has occasionally been described, which is referred to as meningitis-retention syndrome. In contrast, acute urinary retention has rarely been reported in bacterial meningitis. We herein report a case of Streptococcus pneumoniae meningitis presenting with acute urinary retention which led to emphysematous cystitis in an elderly woman. She presented with impaired consciousness and a distended lower abdomen. She was diagnosed with pneumococcal meningitis by lumbar puncture. Abdominal computed tomography revealed the presence of emphysematous cystitis. She completely recovered with antibiotic therapy without any complications. Acute urinary retention can occur secondary to pneumococcal meningitis.
