Virulence determinants in multidrug-resistant Acinetobacter baumannii: comparative phenotypic and genomic analysis of clinical and patient-environmental isolates

Frontiers in Cellular and Infection Microbiology · doi:10.3389/fcimb.2026.1969523 · PubMed 42964070

What
A study from JSS Medical College & Hospital, Mysuru, with Kasturba Medical College, Mangalore, comparing phenotypic virulence traits and genomic virulence-associated genes in multidrug-resistant (MDR) Acinetobacter baumannii isolated from clinical specimens and from patients’ environmental surroundings.
Design
110 non-duplicate MDR A. baumannii isolates (55 clinical and 55 corresponding patient-environmental isolates) were tested for biofilm formation, haemolytic activity, proteolytic activity and siderophore production using standard phenotypic assays. All isolates underwent whole-genome sequencing on the Illumina MiSeq platform, and virulence-associated genes were identified using the Virulence Factor Database (VFDB).
Key findings
Clinical isolates showed significantly higher frequencies of strong biofilm formation (34/55, 61.8% vs. 6/55, 10.9%), haemolytic activity (29/55, 52.7% vs. 13/55, 23.6%) and siderophore production (31/55, 56.4% vs. 17/55, 30.9%) than environmental isolates (P < 0.05), whereas proteolytic activity was comparable (36/55, 65.5% vs. 33/55, 60.0%). Virulence-associated genes were highly prevalent among phenotypically positive isolates, and several were also detected in phenotypically negative isolates, indicating phenotype-genotype discordance.
Limitations
The abstract does not report patient outcomes or the study period; the authors note that gene carriage alone does not necessarily predict phenotypic expression.
Relevance to India
The authors conclude that environmental isolates retained multiple virulence-associated genes, highlighting their potential role as reservoirs for persistence and transmission within healthcare settings, and underscore the importance of continuous environmental surveillance and infection prevention strategies.

A meta-analysis-guided sampling plan for estimating the prevalence of 10 zoonotic and 4 transboundary animal diseases across India

Frontiers in Veterinary Science · doi:10.3389/fvets.2026.1919244 · PubMed 42964325

What
A study from the ICAR-National Institute of Veterinary Epidemiology and Disease Informatics (NIVEDI), Bengaluru, with partners including Tamil Nadu Veterinary and Animal Sciences University, Chennai, to build a sampling plan for estimating the prevalence of 10 zoonotic diseases (brucellosis, tuberculosis, Q-fever, scrub typhus, Japanese encephalitis, Crimean-Congo haemorrhagic fever, cysticercosis, cryptosporidiosis, listeriosis, salmonellosis) and four transboundary animal diseases (TADs: swine influenza, porcine reproductive and respiratory disease, lumpy skin disease, African swine fever) across India.
Design
A systematic review and meta-analysis conducted in accordance with PRISMA guidelines (random-effects model, heterogeneity quantified by I²) provided preliminary prevalence estimates. Combined with predetermined assay sensitivity and specificity, these were used to generate a two-stage stratified random surveillance plan at a 95% confidence level, using an in-house epi-calculator with the village as the stratification variable for the targeted animal species in different states.
Key findings
The pooled prevalence estimates of the 14 diseases ranged from 4 to 30%. Based on these estimates, a village-level surveillance plan comprising 34,975 samples across 2,018 villages was generated for India.
Limitations
The plan is a design for future surveillance: its inputs are pooled estimates from published studies, and the paper does not itself report new field prevalence data.
Relevance to India
The authors describe this as the first scientifically rigorous meta-analysis-based sampling plan under one platform for many diseases, which could facilitate a robust prevalence study and serve as a tool for monitoring zoonotic diseases and TADs that are a threat to India.
