Melioidosis is an infection caused by the gram-negative bacterium Burkholderia pseudomallei. This disease is endemic in Southeast Asia and North Australia with sporadic occurrence in temperate countries, mostly imported from travellers. Any organ can be involved in melioidosis whereby Burkholderia pseudomallei causes an acute inflammatory reaction with rapid development of small abcesses which tend to coalesce to form larger abscesses. Cutaneous manifestations vary greatly. We report a man with systemic melioidosis who presented with cutaneous lesions.

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.

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.

Background: Melioidosis is a multisystem infectious disease caused by the environmental bacterium . Osteomyelitis (OM) and septic arthritis (SA) are uncommon primary presentations for melioidosis but important secondary foci, often requiring prolonged therapy and multiple surgeries. We characterized the epidemiology, presentation, treatment, and outcomes of patients from 24 years of the Darwin Prospective Melioidosis Study (DPMS).

Burkholderia pseudomallei, the causative agent of melioidosis, is intrinsically resistant to multiple classes of antibiotics and primarily affects immunocompromised individuals, such as those with poorly controlled diabetes or malignancies. In this case, a 58-y-old female farmer with poorly controlled diabetes (HbA1c of 11.4%), metastatic breast cancer with chemotherapy-induced pancytopenia and disseminated melioidosis showed no improvement despite receiving antibiotics and supportive care.

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.
