Coxiella burnetii Infection in Livestock, Pets, Wildlife, and Ticks in Latin America and the Caribbean: a Comprehensive Review of the Literature

Purpose of the Review Q fever , a bacterial zoonosis caused by Coxiella burnetii, is reported very heterogeneously in humans in Latin America. The objective of this study was to review the data on Coxiella burnetii Infection in animals in Latin America and the Caribbean. Recent Findings A comprehensive literature review was carried out in the 47 countries and territories of Latin America on various search engines and grouped into four groups: livestock, pets, wildlife, and ticks. Summary Thus, 113 studies were selected between 1950 and 2022. Among the 47 countries, only 25 (53%) had at least one publication related to C. burnetii infection in animals. The most productive country was Brazil (N = 51), followed by French Guiana (N = 21), and Colombia (N = 16). Studies in livestock from 20 countries have shown widely varying country-to-country rates of seroprevalence, ranging from 0 to 67%. Some studies from seven countries, especially French Guiana and Brazil, found antibodies and sometimes positive PCR in dogs and cats, generally in the context of investigations around human clustered cases. Knowledge remained fragmented about infection in wildlife from only five countries (Chile, Colombia, Brazil, French Guiana, and Uruguay). C. burnetii infection was identified by PCR in Chiroptera (7 species), Rodentia (6 species), Suina (2 species), Xenartha (1 species), Cingulata (1 species), and Perissodactyla (1 species). Studies on Coxiella sp. in ticks have been performed in 11 countries, mostly in Brazil, and mainly found Coxiella-like endosymbionts. Thus, data on C. burnetii infection in animals are sparse and incomplete in Latin America and the Caribbean, and more research is warranted

Densidad de los armadillos (dasypus spp.) mediante el uso de cámaras la densidad de armadillos trampa y densidad de madrigueras en la Guayana Francesa

Armadillo density estimates are important for species knowledge, but they are unknown in the Guiana Shield. We aimed at estimating Dasypus density through burrow density and camera trapping. We surveyed and trapped burrows in three protected sites in French Guiana, on strip transects covering 4.8 ha in each site, and estimated Dasypus density taking into account burrow measures and occupancy. Population densities ranged between 7.6 and 48.6 animals/km2 for Dasypus sp. nov. and 10.3 and 34.7 animals/km2 for D. kappleri. Dasypus density estimates through burrow survey and exclusive burrow entrance camera trapping is relatively low-cost, non-invasive and reliable.La densidad de armadillos es desconocida en el Escudo guayanés. Nuestro objetivo fue estimar la densidad de Dasypus a través de la densidad de madrigueras y mediante cámaras trampa. Identificamos y monitoreamos madrigueras en tres sitios en Guayana Francesa, en transectos cubriendo 4.8 ha por sitio. Estimamos la densidad poblacional de Dasypus teniendo en cuenta las medidas y la ocupación de las madrigueras. Las densidades poblacionales variaron entre 7.6 y 48.6 animales/km2 para Dasypus sp. nov. y 10.3 y 34.7 animales/km2 para D. kappleri. Estimar la densidad de Dasypus mediante las madrigueras y cámaras trampas es relativamente de bajo costo, no invasivo y confiable.Fil: Schaub, Roxane. Université de Guyane; Guayana Francesa.
