Rickettsiosis Infections in Sarawak: Epidemiological Insights and Public Health Strategies

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2025, Issue 1, 2025.
Rickettsiosis infections pose a significant public health concern in Sarawak, Malaysia. Despite their importance, these infections remain poorly recognised, under‐researched and inadequately documented within the context of the Sarawak region. This comprehensive evaluation seeks to address this knowledge gap by providing an in‐depth analysis of ...

Use of Deep Sequencing to Evaluate Transitions in Microbial Communities in Stranded Sargassum

International Journal of Microbiology, Volume 2025, Issue 1, 2025.
Deep sequencing technologies can be used to evaluate pathogens in environmental samples. The objective of this study was to use this technology to evaluate Sargassum samples that were characterized by different stranding times, one classified as short‐term stranded (STS) and another classified as long‐term stranded (LTS) Sargassum.

Reassessment of the genetic basis of natural rifampin resistance in the genus Rickettsia

MicrobiologyOpen, Volume 13, Issue 4, August 2024.
Contrary to previous studies, the natural resistance of Rickettsia, a genus of intracellular bacteria, to the antibiotic rifampin is not solely due to the Leu‐973 residue in the RNA polymerase β subunit. Abstract Rickettsia, a genus of obligate intracellular bacteria, includes species that cause significant human diseases.

Tools and mechanisms of vacuolar escape leading to host egress in Legionella pneumophila infection: Emphasis on bacterial phospholipases

Molecular Microbiology, Volume 121, Issue 3, Page 368-384, March 2024.
Scheme of how secreted exit‐associated phospholipases are engaged by Legionella pneumophila during lytic escape. 1. L. pneumophila enters the host cell in an endocytic manner. 2. The bacterium actively establishes an intracellular niche (Legionella‐containing vacuole, LCV) which is required for replication.

Paleoserological detection of Coronavirus antigens in dental calculus  of human remains dating from the beginning of the 19th century, French Ardennes

American Journal of Biological Anthropology, Volume 183, Issue 1, Page 165-171, January 2024.
Abstract Objective Vanishing viral RNA restricts our ability to detect ancient pathogens, so, we used paleo serological approaches to trace the dynamics of the Coronavirus in ancient populations. Materials and Methods We investigated 10 ancient dental calculus samples collected from a cemetery dated to the beginning of the 19th century and excavated in
