Leptospirosis, melioidosis, and rickettsioses in the vicious circle of neglect.

The global priorities in the field of infectious diseases are constantly changing. While emerging viral infections have regularly dominated public health attention, which has only intensified after the COVID-19 pandemic, numerous bacterial diseases have previously caused, and continue to cause, significant morbidity and mortality-deserving equal attention. Three potentially life-threatening endemic bacterial diseases (leptospirosis, melioidosis, and rickettsioses) are a huge public health concern especially in low- and middle-income countries.

Case Report: Soft tissue infection with capsular variant: case report from the Lao PDR.

Background: is an environmental bacteria closely related to that rarely causes infection in humans. Some environmental isolates have shown to express a capsular polysaccharide known as capsular variant (BTCV), but human infection has not previously been reported. Although has been identified in environmental samples in Laos before, there have not been any human cases reported.

Use of Comparative Genomics To Resolve an Unusual Case of Aminoglycoside Susceptibility in the Melioidosis Pathogen Burkholderia pseudomallei in Bangladesh.

Melioidosis is an emerging tropical infectious disease with a rising global burden caused by the environmental bacterium Burkholderia pseudomallei. It is endemic in Southeast and South Asia, including Bangladesh. A rare aminoglycoside-susceptible B.

Point mutation P174L of the penA gene endowing ceftazidime resistance to Burkholderia pseudomallei in China.

In a clinical isolate of Burkholderia pseudomallei from Hainan, the association between the emergence of ceftazidime resistance and a novel PenA P174L allele was identified for the first time, providing an understanding of one mechanism by which ceftazidime resistance arises in B. pseudomallei.

Melioidosis in Patients with COVID-19 Exposed to Contaminated Tap Water, Thailand, 2021.

In September 2021, a total of 25 patients diagnosed with COVID-19 developed acute melioidosis after (median 7 days) admission to a COVID-19 field hospital in Thailand. Eight nonpotable tap water samples and 6 soil samples were culture-positive for Burkholderia pseudomallei. Genomic analysis suggested contaminated tap water as the likely cause of illness.
