A case of human melioidosis caused by a novel sequence type of Burkholderia pseudomallei occurred in a child in Malawi, southern Africa. A literature review showed that human cases reported from the continent have been increasing.

Melioidosis is a life-threatening infectious disease caused by the bacterium . Although culture is the gold standard for diagnosing melioidosis, it is time-consuming and delays timely treatment. Non-culture-based diagnostic techniques are interesting alternatives for the rapid detection of melioidosis.

Burkholderia pseudomallei (Bp), causing melioidosis, is becoming a major global public health concern. It is highly endemic in Southeast Asia (SEA) and Northern Australia and is persisting beyond the established areas of endemicity. This study aimed to determine the environmental variables that would predict the most suitable ecological niche for this pathogenic bacterium in SEA by maximum entropy (MaxEnt) modeling.

Food contamination with non-typhoidal (NTS) presents a significant public health risk, underscoring the critical need for rigorous food safety measures throughout the production, distribution, preparation, and consumption stages. Conventional diagnostic strategies are time-consuming and labor-intensive and are thus sub-optimal for throughput NTS detection. Bacteriophages (phages) are highly specialized bacterial viruses and exhibit extreme specificity for their hosts.

Hemolysin co-regulated protein 1 (Hcp1) is a component of the cluster 1 Type VI secretion system (T6SS1) that plays a key role during the intracellular lifecycle of Burkholderia pseudomallei. Hcp1 is recognized as a promising target antigen for developing melioidosis diagnostics and vaccines. While the gene encoding Hcp1 is retained across B.

Burkholderia pseudomallei, a soil-borne bacterium that causes melioidosis, endemic in South and Southeast Asia and northern Australia, is now emerging in new regions. Since the 1990s, cases have been reported in French overseas departments, including Martinique and Guadeloupe in the Caribbean, and Reunion Island and Mayotte in the Indian Ocean, suggesting a local presence of the bacterium. Our phylogenetic analysis of 111 B.
