Korat‐Scrub Typhus Score: A Clinical Tool for Predicting Scrub Typhus in Patients With Acute Undifferentiated Febrile Illness

Tropical Medicine &International Health, EarlyView.
ABSTRACT Objective Scrub typhus is a major cause of acute undifferentiated febrile illness (AUFI) in the Asia–Pacific region. Nonspecific presentation, limited diagnostic accuracy and delayed treatment increase morbidity and mortality. This study aimed to develop a simple clinical score for early diagnosis in adults with AUFI. Methods A cross‐sectional

Infection with the Neorickettsial Organism Stellantchasmus falcatus Agent in an Arctic Fox (Vulpes lagopus)

Veterinary Clinical Pathology, EarlyView.
ABSTRACT A 1‐year‐old female‐intact arctic fox (Vulpes lagopus) presented for diarrhea, lethargy, severe thrombocytopenia, and hyperbilirubinemia. Blood film evaluation revealed intracytoplasmic coccoid bacteria within moderate numbers of leukocytes consistent with infection by a rickettsial organism.

Comparison of real-time quantitative PCR and culture for the diagnosis of emerging Rickettsioses. [PDF]

PLoS Neglected Tropical Diseases, 2012
BACKGROUND: Isolation of Rickettsia species from skin biopsies may be replaced by PCR. We evaluated culture sensitivity compared to PCR based on sampling delay and previous antibiotic treatment.

First Reported Case of Fulminant Weil's Disease in South Khorasan, Eastern Iran: Diagnostic Challenges in a Non‐Endemic Region and Implications for Military Deployment

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Weil's disease should be considered even in non‐endemic regions when compatible clinical findings are accompanied by relevant exposure history. This case is epidemiologically notable as the first documented report from South Khorasan Province, highlighting the diagnostic challenges of leptospirosis in non‐endemic settings and the potential ...

Spatial Distribution and Host‐Specific Patterns of Avian Haemosporidian Infections in a Semi‐Arid Region of Northeastern Iran

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
A survey of 263 birds across 10 species in Semnan Province, Iran, revealed a 22.1% prevalence of avian haemosporidian infections, dominated by Haemoproteus spp. Pigeons showed significantly higher infection risk. Spatial analysis identified clustering in Shahroud County, suggesting local climatic and ecological conditions influence parasite ...

Serological and molecular detection of spotted fever group Rickettsia in a group of pet dogs from Luanda, Angola

Parasites & Vectors, 2017
Background Infections with tick-borne rickettsiae can cause diseases well known in humans but still not so well characterized in dogs. Susceptibility to infection depends on the virulence of Rickettsia spp.

Pathways of Protein Secretion in Prokaryotes and Eukaryotes: Molecular Mechanisms, Biological Functions, and Therapeutic Opportunities

MedComm, Volume 7, Issue 6, June 2026.
This graphical abstract delineates noncanonical protein secretion systems across eukaryotes and prokaryotes. Eukaryotic UcPS covers four ER–Golgi bypass pathways, enabling rapid leaderless protein export via direct transmembrane translocation or vesicle‐mediated release.
