The socioecological conditions of Mexican regions are conducive to the spread of vector-borne diseases. Although there are established treatment guidelines for dengue and rickettsiosis, diagnosis is complicated. The objective of this work was to identify epitopes of Rickettsia and dengue virus that could be used in serology screening against vector-borne diseases.

- * A scientific symposium held from November 8-10, 2023, brought together experts from academia and health authorities to discuss RMSF challenges and potential solutions.
- * The One Health approach is emphasized as a key strategy to enhance surveillance, diagnosis, and prevention efforts to combat RMSF effectively in Mexico.
Potential zoonotic role of the tick Amblyomma cf. oblongoguttatum (Ixodida: Ixodidae) in the bacterial transmission of Ehrlichia chaffeensis (Rickettsiales: Anaplasmataceae) in a deciduous tropical forest in Mexico.

Article Synopsis
- Ehrlichia chaffeensis is a bacterium that can be associated with tick species and has been identified in Mexico, where only two related species have been recorded.
- A study was conducted in the Chamela-Cuixmala Biosphere Reserve, Jalisco, Mexico, to detect Ehrlichia bacteria in ticks collected from mammals and vegetation; a total of 204 ticks were analyzed.
- The results showed that 1.47% of ticks tested positive for Ehrlichia sp., particularly in larval and nymph stages of Amblyomma species, indicating a potential zoonotic risk, although the exact role of these ticks as vectors is still unclear.
Introduction: is an obligate, intracellular pathogen and the causative agent of Rocky Mountain spotted fever (RMSF). RMSF is an important zoonotic disease due to its high fatal outcome in humans. The difficulty of clinical diagnosis due to the low sensitivity and specificity of current diagnostic methods are a principal setback.
