The paper investigates the distribution of Mycobacterium tuberculosis Lineage 4 in Southeast Asia using genomic data, finding that most L4 sub-clades in the region have no recent European origin and may involve China as an intermediate.

This study compares the virulence of Cryptococcus neoformans ST5 and non-ST5 isolates in HIV-infected and uninfected patients in Vietnam, finding ST5 isolates show greater variability and initial inflammatory response but lower fungal burden in mice.

This study uses whole-genome sequencing of Salmonella Typhi isolates from travelers to analyze genotype distribution and antimicrobial resistance patterns across regions.

This paper identifies genetically distinct ST313 Salmonella isolates causing gastroenteritis in the UK and invasive disease in Africa, highlighting their evolutionary divergence and adaptation to different environments.
