First Identification and Description of Rickettsioses and Q Fever as Causes of Acute Febrile Illness in Nicaragua

BackgroundRickettsial infections and Q fever present similarly to other acute febrile illnesses, but are infrequently diagnosed because of limited diagnostic tools. Despite sporadic reports, rickettsial infections and Q fever have not been prospectively studied in Central America.Methodology/Principal FindingsWe enrolled consecutive patients presenting with undifferentiated fever in western Nicaragua and collected epidemiologic and clinical data and acute and convalescent sera. We used ELISA for screening and paired sera to confirm acute (≥4-fold rise in titer) spotted fever and typhus group rickettsial infections and Q fever as well as past (stable titer) infections. Characteristics associated with both acute and past infection were assessed.Conclusions/SignificanceWe enrolled 825 patients and identified acute rickettsial infections and acute Q fever in 0.9% and 1.3%, respectively. Clinical features were non-specific and neither rickettsial infections nor Q fever were considered or treated. Further study is warranted to define the burden of these infections in Central America.

“…Regarding livestock, two exotic ticks (i.e., Rhipicephalus microplus and A. variegatum) are considered to be major threats to the industry [47,48]. Rhipicephalus microplus, a onehost tick, is the most economically important tick in the global livestock industry and is associated with the transmission of Anaplasma marginale, Anaplasma centrale, Babesia bigemina, and Babesia bovis [49].…”

“…Rhipicephalus microplus, a onehost tick, is the most economically important tick in the global livestock industry and is associated with the transmission of Anaplasma marginale, Anaplasma centrale, Babesia bigemina, and Babesia bovis [49]. In CAC, R. microplus is widely distributed and has been reported in different climatic conditions at altitudes varying from 0 to 2000 m [13,14,48,50]. Amblyomma variegatum is a three-host tick that, in addition to E. ruminantium, R. africae, and R. conorii, also transmits pathogens of the genera Ehrlichia and Theileria [10,[51][52][53].…”

Ticks and Tick-Borne Diseases in Central America and the Caribbean: A One Health Perspective

Ticks have complex life cycles which involve blood-feeding stages found on wild and domestic animals, with humans as accidental hosts. At each blood-feeding stage, ticks can transmit and/or acquire pathogens from their hosts. Therefore, the circulation of tick-borne pathogens (TBPs), especially the zoonotic ones, should be studied in a multi-layered manner, including all components of the chain of infections, following the ‘One Health’ tenets. The implementation of such an approach requires coordination among major stakeholders (such as veterinarians, physicians, acarologists, and researchers) for the identification of exposure and infection risks and application of effective prevention measures. In this review, we summarize our current knowledge on the epidemiology of tick-borne diseases in Central America and the Caribbean and the challenges associated with the implementation of ‘One Health’ surveillance and control programs in the region.

“…En un estudio se demostró la presencia de R. microplus en cuatro países centroamericanos, incluyendo a Honduras (4,11,12,13), donde también se ha reportado resistencia de 66% a deltametrina, 55-62% a flumetrina, y 58% a ciflutrina. Sin embargo, no se ha evaluado a uno de los piretroides ampliamente usado en Honduras: la cipermetrina.…”

Objetivo. El presente estudio tiene por objetivo evaluar la eficacia in vitro de cinco productos comerciales empleados en el sitio con mayor producción de bovinos en Honduras. Materiales y métodos. Se colectaron garrapatas en cuatro fincas ganaderas en Catacamas (14°50' N, 85°53' S), considerando una cantidad de 300 bovinos. Se colectaron aproximadamente 1,000 teleóginas de R. microplus para implementar un grupo control y cinco grupos de comparación, cada grupo incluyó dos replicas con 50 individuos. Se realizó el método de inmersión con cada uno de los cinco productos comerciales y se estimaron las siguientes tasas: mortalidad, ovoposición, eclosión, eficiencia reproductiva y eficacia del producto según lo propuesto por Drummond et al., 1973. Resultados. Cuatro de los productos comerciales con los siguientes ingredientes activos (Producto 1: cipermetrina, clorpirifós, butóxido de piperonilo. Producto 2: cipermetrina, ethion, butóxido de piperonilo. Producto 3: amitraz. Producto 4: coumaphos), obtuvieron una eficacia superior al 90%, sobresaliendo las familias químicas de amidinas, organofosforados y la combinación de organofosforados con piretroides para el control de R. microplus en la localidad de Catacamas, Honduras. Por otra parte, un producto (Producto 5: cipermetrina), presenta una eficacia del 68%. Este producto de la familia de los piretroides muestra problemas de eficacia con mortalidad del 33% y los individuos sobrevivientes presentan una tasa reproductiva del 30%. Conclusiones. Es necesario modificar el uso de la cipermetrina en Catacamas, Honduras, incorporando un control integral de parásitos para reducir la posibilidad de resistencia antiparasitaria de R. microplus.
