A Multiplex PCR assay for a differential diagnostic of rickettsiosis, Lyme disease and scrub typhus

Journal of Vector Borne Diseases, 2022
Background & objectives: Coexistence of tick-borne diseases in some regions in Latin America makes the diagnosis difficult due to shared initial signs and symptoms. Rickettsiosis, Lyme disease and recently, scrub typhus are gaining more importance.

New Orientia tsutsugamushi Strain from Scrub Typhus in Australia

Emerging Infectious Diseases, 1998
In a recent case of scrub typhus in Australia, Orientia tsutsugamushi isolated from the patient's blood was tested by sequence analysis of the 16S rDNA gene. The sequence showed a strain of O. tsutsugamushi that was quite different from the classic Karp,

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 ...

Diagnostic Value of Neutrophil CD64 in Differentiating Scrub Typhus From Febrile Diseases

Immunity, Inflammation and Disease, Volume 14, Issue 3, March 2026.
ABSTRACT Background Scrub typhus, lacks specific early symptoms, and traditional serological tests have low sensitivity. This study shows that CD64 has superior diagnostic performance compared to CRP and PCT in bacterial infections. Methods This retrospective study analyzed 242 febrile patients admitted to the Jiangsu Province (Suqian) Hospital ...

CD8+ T cells provide immune protection against murine disseminated endotheliotropic Orientia tsutsugamushi infection. [PDF]

PLoS Neglected Tropical Diseases, 2017
Scrub typhus, caused by a Gram-negative obligately intracellular coccobacillus, Orientia tsutsugamushi, is a long neglected but important tropical disease. Orientia tsutsugamushi causes illness in one million people each year, and 1 billion people are at

Concurrent Scrub Typhus, Dengue, and Leptospirosis: A Rare Triple Co‐Infection: A Case Report and Comprehensive Literature Review

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT In endemic areas, acute undifferentiated febrile illness has a wide differential with overlapping features that can lead to misdiagnosis. Although triple co‐infection with scrub typhus, dengue, and leptospirosis is extremely rare, high clinical suspicion and early detection are vital to avoid delayed treatment, multi‐organ dysfunction, and ...

A comparison of super‐resolution microscopy techniques for imaging tightly packed microcolonies of an obligate intracellular bacterium

Journal of Microscopy, Volume 301, Issue 2, Page 187-205, February 2026.
Abstract Conventional optical microscopy imaging of obligate intracellular bacteria is hampered by the small size of bacterial cells, tight clustering exhibited by some bacterial species and challenges relating to labelling such as background from host cells, a lack of validated reagents, and a lack of tools for genetic manipulation.

Identification of Potential Therapeutic Agents for Primary Amebic Meningoencephalitis Using Text Mining and Bioinformatics Analyses

Analytical Cellular Pathology, Volume 2026, Issue 1, 2026.
Naegleria fowleri, the brain‐eating ameba, causes primary amebic meningoencephalitis (PAM), a fatal infectious disease that affects the central nervous system (CNS). We aimed to evaluate the functions and potential drugs targeting PAM using text mining and bioinformatics analyses.
