Emerging Neisseria meningitidis ST-1466 and ST-11026 as urogenital pathogens in China.
Article in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNeisseria meningitidis, known primarily for causing severe sepsis and meningitis, has also been identified as a cause of urethritis. However, reports of such cases in China are scarce. We present two cases of N. meningitidis strains isolated from the urogenital tract in China in 2024.
methodsTwo N. meningitidis isolates were recovered from the urogenital tract. Whole genome sequencing (WGS) was performed to identify genogroup and sequence type (ST), factor H binding protein (fHbp), capsule polysaccharide synthesis (cps) and nitrite reductase (aniA) gene. Phylogenetic analysis was also performed.
resultsThe first case was an infertile female with significant symptoms of urethritis. The strain isolated from her cervical secretion (FE-07) was identified as genogroup Y, ST-1466, clone complex (cc)-174, fHbp variants 2.21, harboring intact cps locus, and frameshift-mutated aniA gene. The second case was an infertile male presenting with mild pruritus of the glans. The strain recovered from his semen (FE-08) was classified as nongroupable, ST-11026, cc-32, fHbp variants 1.1, harboring incomplete cps locus, and frameshift-mutated aniA gene. Both STs of N. meningitidis have not been reported in China previously and are phylogenetically distinct from strains with the same STs in the NCBI GenBank database.
conclusionsOur study highlights the emergence of N. meningitidis as a urogenital pathogen in China and underscores the need for vigilance against potential outbreaks of meningococcal urethritis.
