Clinical characteristics and trends in the antimicrobial susceptibility profile of Streptococcus suis infections in a large tertiary hospital, Thailand, 2007-2023.
Article in PLoS neglected tropical diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundStreptococcus suis is an emerging pathogen causing invasive zoonotic infections in humans. Antimicrobial resistance (AMR) to penicillin, macrolides, and tetracyclines has emerged in S. suis-infected swine. AMR among zoonotic S. suis strains causes a critical concern for human infection and antimicrobial treatment options. Thus, the study aims to delineate the clinical characteristics and to explore the changing pattern of the antimicrobial susceptibility (AST) of S. suis infection in humans.
methodsWe conducted a chart review of adult patients with culture-confirmed S. suis infection in any body sites at Siriraj Hospital, Bangkok, Thailand, between May 2007 and May 2023. We also reviewed the AST profile of S. suis isolates during the study period.
resultsOver 16 years, 86 adult patients with S. suis infection were identified (59.3% male, mean age 59.29 ± 14.46 years). Of them, 60.5% had comorbidities (hypertension 43%, dyslipidemia 23.3%, diabetes mellitus 20.9%, alcoholism 19.8%), and 35.0% had swine contact a median of 1 (0.0-6.5) days before onset. Clinical presentations included septicemia (91.9%), meningitis (30.2%), endocarditis (26.7%), and septic arthritis (9.3%), leading to multiorgan dysfunction (32.5%), cardiopulmonary failure (26.8%), renal failure (17.4%), and septic shock (14.0%). Mortality was 7%. Definitive therapy primarily used ceftriaxone (76.7%) or penicillin (8.1%) as a basis regimen. Among S. suis isolates tested, 48.2% were susceptible to penicillin (median MIC 0.064 [0.047-0.094] µg/mL), 96.5% were susceptible to ceftriaxone (median MIC 0.380 [0.110-0.500] µg/mL), and susceptibility to vancomycin, ofloxacin, tetracyclines, and clindamycin was 100%, 96.4%, 4.8%, and 1.2%, respectively. Penicillin MICs increased significantly (p < 0.001), while other agents' profiles remained stable.
conclusionsS. suis can cause severe human infection, leading to fatal complications. S. suis displayed an upward trend of penicillin MICs and resistance to several antimicrobial agents. These findings underscore the need to monitor emerging resistance.
