Post-procedural Wound Infections by Mycobacterium fortuitum: A Series of Seven Cases From Eastern India

Cureus · doi:10.7759/cureus.117663 · PubMed 43001065

What
A case series from the Department of Microbiology, Manipal-Tata Medical College, Jamshedpur, with AIIMS Kalyani, describing the clinical, microbiological and therapeutic features of post-procedural wound infections caused by the rapidly growing nontuberculous mycobacterium Mycobacterium fortuitum in Eastern India.
Design
Cross-sectional observational study at a tertiary care teaching hospital between September 2024 and August 2025. Specimens were processed for Ziehl-Neelsen staining, routine bacterial culture and mycobacterial culture (BacT/ALERT MP liquid culture and Middlebrook medium); species identification was by MALDI-TOF MS. Seven patients with culture-confirmed M. fortuitum infection were described.
Key findings
The mean patient age was 39 years, and six (85.7%) were female. Five patients (71.4%) had undergone their primary procedure at peripheral nursing homes. Patients presented with chronic non-healing wounds, persistent serous or seropurulent discharge and poor response to conventional antibacterial therapy. Direct Ziehl-Neelsen staining was positive in two (28.6%) cases, whereas all isolates were recovered by BacT/ALERT MP liquid culture within 4-11 days. All patients received prolonged combination antimicrobial therapy, one required surgical debridement, and complete clinical healing was achieved in all cases.
Limitations
Small single-centre descriptive series; the abstract does not report susceptibility results or the source of infection.
Relevance to India
The authors highlight M. fortuitum as an overlooked cause of chronic post-procedural wound infection, particularly where routine bacterial cultures are negative, and the cluster of procedures at peripheral nursing homes is relevant to surgical IPC and laboratory practice.

Modelling indirect protection from typhoid conjugate vaccines in the TyVAC-Bangladesh trial

Epidemiology and Infection · doi:10.1017/S0950268826102337 · PubMed 43000950

What
A modelling analysis, with authors from Yale School of Public Health, icddr,b and the Oxford Vaccine Group, examining why indirect (herd) protection from typhoid conjugate vaccine (TCV) was modest and not statistically significant in the TyVAC-Bangladesh cluster-randomised trial, in which one TCV dose in children aged 9 months to <16 years gave strong direct protection.
Design
The trial was simulated with a primary transmission dynamic model calibrated against clinical surveillance data and an alternative model incorporating serological data, testing transmission across cluster boundaries, limited protection against infection and insufficient coverage as explanations.
Key findings
Vaccinating 64% of eligible children (the observed trial coverage) induced up to 67% and 54% indirect protection in the primary and alternative models, respectively, depending on chronic-carrier transmissibility and TCV efficacy against S. Typhi infection. Trial results were consistent with 15% to 85% TCV efficacy against infection in the primary model and 60% to 90% in the alternative model. If adults had been vaccinated at the same coverage as children, indirect protection was estimated to rise from 19% to 40%-57%.
Limitations
Model-based estimates whose ranges depend on assumptions about carrier transmissibility and vaccine efficacy against infection.
Relevance to South Asia
The authors conclude that TCV protects against transmission from acute infections and that low observed indirect protection can be explained by transmission from unvaccinated adults, relevant to TCV programme design in typhoid-endemic South Asia.
