This is a descriptive metagenomic survey identifying bacterial sequences of public health relevance—including Yersinia pestis, Bartonella elizabethae, Acinetobacter baumannii, and Bordetella spp.—in tissue and flea samples from commensal small mammals at Bangkok Port between June and August 2025. The study provides evidence that rats, shrews, and their ectoparasites may harbour zoonotic and antimicrobial-resistant pathogens at an international cargo hub, but does not quantify prevalence, transmission risk, or clinical impact.
Observational cross-sectional study with shotgun metagenomic sequencing. Commensal small mammals (rats and shrews) and their ectoparasites (fleas) residing in the international cargo vessel berth of Bangkok Port, Khlong Toei District, Bangkok, Thailand. In 2025, 200 traps were deployed, yielding 54 captures.. Intervention: Shotgun metagenomic sequencing of tissue samples and ectoparasites following host read depletion.. n = 54. Bangkok Port (Khlong Toei Port), Thailand; eight warehouse areas within the international cargo vessel berth..
Shotgun metagenomic analysis identified bacterial taxa of public health relevance including Bordetella spp., Yersinia pestis, Bartonella elizabethae, and Acinetobacter baumannii in small mammal and flea samples. Yersinia pestis was identified as a shared taxon among rats, shrews, and their associated fleas. Virulence factor and antibiotic resistance gene profiles indicated pathogenic potential and drug resistance in detected organisms.

The detection of pathogenic and drug-resistant bacterial sequences in port-resident small mammals supports enhanced surveillance at international maritime gateways, but does not directly evidence human transmission risk or inform immediate clinical practice without epidemiological validation.
This is a descriptive metagenomic surveillance study from a single port location over one season, identifying potential zoonotic pathogens without quantitative effect measures, comparators, or validation of detected sequences in clinical or epidemiological outcomes.

Commensal small mammals, such as rats and shrews, are recognized reservoirs for numerous zoonotic pathogens; however, their role in pathogen circulation at transport hubs remains underexplored. This study employs shotgun metagenomic sequencing to characterize microbial communities and assess zoonotic potential in tissue samples from commensal small mammals captured at Bangkok Port, an international cargo shipping hub in Thailand between June and August 2025. Following host read depletion, taxonomic profiling was performed to identify bacterial taxa of public health relevance, including sequences assigned to Bordetella spp., Yersinia pestis, Bartonella elizabethae, and Acinetobacter baumannii. The virulence factor and antibiotic resistance gene profiles revealed that some of these pathogens have pathogenic potential and are related to drug-resistant bacteria. In addition, Y. pestis was identified as a shared taxon among rats, shrews, and their associated fleas. The findings support the ecological roles of mammalian hosts and their ectoparasites as reservoirs for pathogens of public health concern. These results emphasize the need to strengthen surveillance programs for commensal small mammals to monitor and mitigate the spread of transboundary pathogens at international maritime gateways.
