“…Central America and the Caribbean region encompass a vast biodiversity of fauna, including ticks, with approximately 80 species reported to date [13][14][15][16][17]. Despite the fact that TBDs have been reported in most countries in the CAC region, more epidemiological studies are needed to determine the ecology and prevalence of ticks and TBDs in the animal population of the region [4,18].…”

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.

“…The brown dog tick, Rhipicephalus sanguineus , is one of the main arthropod vectors responsible for the transmission of TBPs in dogs worldwide [ 5 ]. A previous study found that this tick is the most prevalent species found on dogs on the island of Tobago [ 6 ]. Rhipicephalus sanguineus ticks have been implicated in the transmission of a range of canine TBPs, including Anaplasma platys, Babesia canis , Ehrlichia canis , Hepatozoon canis and Rickettsia spp.…”

“…Tick infestations and TBDs of the canine population have been reported throughout the Caribbean [ 6 , 22 , 33 , 34 , 35 , 36 , 37 ]. However, very little or no reported data is available for some islands, including Tobago, the smaller of the two islands that comprise the Republic of Trinidad and Tobago.…”

“…In November 2020, a cluster of dogs exhibiting clinical signs consistent with tick-borne illness was reported in Charlotteville, a small fishing village in Tobago. Dogs on this island are known to be infested with R. sanguineus and A. ovale ticks [ 6 ]. While diagnostic methods such as clinical presentation, microscopic detection of pathogens in peripheral blood smears, serological testing (lateral flow test kits) and response to chemotherapeutic agents are used to diagnose tick-borne illness in animals in Tobago, their sensitivity and specificity are not reliable.…”

Eight hunting dogs were visited by a state veterinarian on the island of Tobago, Trinidad and Tobago, West Indies, as owners reported anorexia and paralysis in five of their dogs. The veterinarian observed a combination of clinical signs consistent with tick-borne illness, including fever, anorexia, anaemia, lethargy and paralysis. Blood and ticks were collected from each dog and submitted to a diagnostic laboratory for analysis. Microscopic analysis revealed a mixed infection of intracytoplasmic organisms consistent with Babesia spp. (erythrocyte) and Ehrlichia spp. (monocyte), respectively, from one dog, while a complete blood count indicated a regenerative anaemia (n = 1; 12.5%), non-regenerative anaemia (n = 4; 50%), neutrophilia (n = 3; 37.5%), lymphocytosis (n = 2; 25%), thrombocytopaenia (n = 3; 37.5%) and pancytopaenia (n = 1; 12.5%). DNA isolated from the eight blood samples and 20 ticks (16 Rhipicephalus sanguineus and 4 Amblyomma ovale) were subjected to conventional PCR and next-generation sequencing of the 16S rRNA and 18S rRNA gene for Anaplasma/Ehrlichia and Babesia/Theileria/Hepatozoon, respectively. The DNA of Ehrlichia spp., closely related to Ehrlichia canis, was detected in the blood of three dogs (37.5%), Anaplasma spp., closely related to Anaplasma marginale, in two (25%), Babesia vogeli in one dog (12.5%) and seven ticks (35%) and Hepatozoon canis and Anaplasma spp., in one tick (5%), respectively. These findings highlight the need to test both the vector and host for the presence of tick-borne pathogens when undertaking diagnostic investigations. Further studies are also warranted to elucidate the susceptibility of canids to Anaplasma marginale.
