Abstract
Ticks are responsible for transmission of multiple bacterial, parasitic and viral diseases. Tick-borne diseases (TBDs) occur particularly in tropical and also subtropical areas. The frequency of these TBDs has been increasing and extending to new territories in a significant way, partly since ticks’ populations are highly favored by prevailing factors such as change in land use patterns, and climate change. Therefore, in order to obtain accurate estimates of mortality, premature mortality, and disability associated about TBDs, more molecular and epidemiological studies in different regions of the world, including Latin America, are required. In the case of this region, there is still a limited number of published studies. In addition, there is recently the emergence and discovering of pathogens not reported previously in this region but present in other areas of the world. In this article we discuss some studies and implications about TBDs in Latin America, most of them, zoonotic and with evolving taxonomical issues.

Additional, new species are being reported; their pathogenicity has not been definitely confirmed, they should be considered as potential pathogens13. Ehrlichiosis is another Tick-borne diseases (TBDs) caused by rickettsial organisms of the genus Ehrlichia14,15
Tick and TBDs investigators, vet doctors, medical and public health practitioners should work to share their expertise on different aspects of TBDs, such as tick ecology, disease transmission, diagnostics, and treatment, in order to face the challenges of scientific, political, and public engagement for TBD research and control in this region33
Summary
This article is included in the Emerging Diseases and Outbreaks gateway. University of Uberlandia, Uberlândia, Brazil Any reports and responses or comments on the article can be found at the end of the article. Additional, new species are being reported; their pathogenicity has not been definitely confirmed, they should be considered as potential pathogens13 Ehrlichiosis is another TBD caused by rickettsial organisms of the genus Ehrlichia. In Venezuela, detection of Anaplasma platys has been described in humans Those patients were bitten by Rhipicephalus sanguineus and suffered chronic non-specific clinical signs, including headaches and muscle pains, supporting A. platys as a zoonotic tick-borne pathogen. Etiological agents of the group of Rickettsial, including those in the genuses Anaplasma, Neorickettsia, Ehrlichia, and Rickettsia, are relevant and often vector-borne organisms of canines and felines, and of bovine, livestock and other animals, which appears to be a wide range of hosts
