Evidence for a peptidoglycan‐like structure in Orientia tsutsugamushi [PDF]

Molecular Microbiology, 2017
Summary Bacterial cell walls are composed of the large cross‐linked macromolecule peptidoglycan, which maintains cell shape and is responsible for resisting osmotic stresses. This is a highly conserved structure and the target of numerous antibiotics.

Assessment of a Sensitive qPCR Assay Targeting a Multiple-Copy Gene to Detect Orientia tsutsugamushi DNA

Tropical Medicine and Infectious Disease, 2019
Scrub typhus is caused by an obligated intracellular organism, Orientia tsutsugamushi (Orientia). The disease was traditionally thought to be limited in the tsutsugamushi triangle.

Rickettsiales in South America: A Systematic Review of Their Molecular Detection and Distribution in Arthropods and Vertebrates

Public Health Challenges, Volume 5, Issue 2, June 2026.
ABSTRACT Bacteria of the order Rickettsiales comprise a diverse group of obligate intracellular microorganisms that are globally distributed and highly prevalent in tropical and subtropical regions. In South America, these bacteria have been associated with arthropod vectors, such as ticks, fleas, mites, lice, and certain dipterans, as well as with a ...

Leptotrombidium imphalum Chiggers as Vector for Scrub Typhus in Human Settlements, India, 2022–2023

Emerging Infectious Diseases
Scrub typhus is a common bacterial infection in many parts of Asia. The causative agent, Orientia tsutsugamushi, is transmitted by trombiculid mite (chigger) larvae that require small mammals as maintaining hosts.
