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 ...

Salmonella Typhi and Salmonella Paratyphi A elaborate distinct systemic metabolite signatures during enteric fever. [PDF]

, 2014
The host-pathogen interactions induced by Salmonella Typhi and Salmonella Paratyphi A during enteric fever are poorly understood. This knowledge gap, and the human restricted nature of these bacteria, limit our understanding of the disease and impede the

Mitochondrial Dysfunction in Ehrlichia canis Infection

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Transmitted by tick vectors, Ehrlichia canis (E. canis) is a Gram‐negative, obligate intracellular bacterium of zoonotic concern that infects both canine and human hosts. Its pathogenesis centers on the targeting of mononuclear phagocytes, where it establishes an intracellular niche by suppressing phagolysosomal fusion and evading immune detection ...

Bayesian population‐based assessment of ascertainment bias in flea‐borne typhus surveillance in California, 2011–2019

Medical and Veterinary Entomology, Volume 39, Issue 4, Page 765-775, December 2025.
Although flea‐borne typhus is historically associated with poorer living conditions, FBT surveillance reporting is associated with greater socioeconomic advantage at the population level. FBT surveillance may be biased towards socioeconomic advantage in its ascertainment of surveillance data.
