“…The infestation interval ranged between 1 and 8 specimens. Tick species found in the present study have been previously identified in Yucatan, Mexico ( Solís Hernández et al ., 2015 ; Rodríguez-Vivas et al ., 2016 ; Martínez-Ortiz et al ., 2019 ).…”

Background: Hunting activity in the Mayan communities has increased due to COVID-19 and domestic dogs have gained more importance. Due to its proximity to humans, domestic dogs are a bridge between tick-borne diseases and humans and their peri-domestic environment. In Mexico, and especially in rural regions, there were not adequate records of tick-borne diseases during the SARS-CoV-2 pandemic. Aim: Identify tick-borne diseases (TBD) of ticks collected during the COVID-19 pandemic in a rural community. Methods: Tick capture was carried out in March 2021, in Teabo, Yucatan. Ticks were removed using from domestic dogs and placed in ethanol. Collected ticks were morphological identified and underwent DNA extraction and a partial segment of the mitochondrial 16S-rDNA gene was amplified to corroborate the tick species. The DNA was screened for the presence of Anaplasma spp., Borrelia spp., Ehrlichia spp., and Rickettsia spp.. Purified amplification products were submitted for sequencing and the results were compared to those deposited in GenBank using BLAST. Results: We collected 33 ectoparasites, Ixodes affinis, Rhipicephalus sanguineus, Rhipicephalus microplus and Amblyomma mixtum on 11 hunting dogs. The most frequently ectoparasite was Rh. sanguineus (66%). We detected the presence of DNA of Rickettsia endosymbionte in Ixodes affinis and Anaplasma platys in Rhipicephalus sanguineus. R. endosymbionte presented a similarity of 100% with the partial sequence of Rickettsia endosymbiont of Ixodes affinis isolate IACACTM001 16S ribosomal RNA gene and the sequence of Anaplasma platys had a similarity of 100% with the partial sequence of the isolate 23-33TX 16S ribosomal RNA gene of Anaplasma platys from dogs from Texas, USA and with the partial sequence of the isolate L134 16S ribosomal RNA gene of Ehrlichia canis from dogs from Piura, Peru. Conclusion: We confirmed for the first time the presence of Anaplasma platys in Rh. sanguineus and R. endosymbiont in I. affinis ticks from dogs in the state of Yucatan.

“…Their importance is also reflected in the epidemiological fact that some active cases of rickettsiosis in humans have been associated with Rickettsia infection in these companion animals due to the closeness and coexistence with them, favouring the possibility of their ectoparasites passing to humans (Breitschwerdt et al, 1987). Likewise, domiciliated dogs are hosts of different genera of vector ticks (Martínez‐Ortiz et al, 2019) that can eventually parasitize humans and generate the zoonotic transmission cycle of Rickettsia (Saraiva et al, 2014; Torres‐Castro, Reyes‐Novelo, et al, 2022).…”

Rickettsia parkeri belongs to the spotted fever group (SFG) of the Rickettsia genus. This bacterium causes mild rickettsiosis in humans and is mainly transmitted by Amblyomma ticks. Its medical importance is emerging in the Americas, including Mexico. Synanthropic rodents and domiciled dogs participate as accidental hosts in epidemiological cycles of Rickettsia of the SFG. The aim is to report the presence of R. parkeri in synanthropic rodents and domiciled dogs from a rural community of Yucatán, Mexico. Rodents were captured, and plasma samples were taken from dogs in 48 households from Ucú, Yucatán, Mexico. A spleen sample (rodents) and plasma (dogs) were used in the propagation of Rickettsia on Vero cells. These infected cells were used in the extraction of genomic DNA. Rickettsia DNA was identified using a semi‐nested PCR (snPCR); some products were sent for sequencing. The recovered sequences were analysed with bioinformatics programs, and a phylogenetic tree was built to determine the Rickettsia species. One hundred animals were sampled: 36 synanthropic rodents and 64 dogs. The snPCR evidenced the presence of Rickettsia DNA in 10 rodents (10/36, 27.8%) and 18 dogs (18/64, 28.1%), which represents a global frequency of 28% (28/100) in this study. The bioinformatics analysis yielded homology to R. parkeri and was demonstrated in the phylogenetic tree. The first evidence of the presence of R. parkeri in synanthropic rodents (Mus musculus) from Mexico is presented; likewise, the participation of domestic dogs in the transmission cycle of this bacterium with potential importance in public health is confirmed.

“…Although there are reports of rickettsial infections in native ticks (including species of Amblyomma, Haemaphysalis, Ixodes, and Ornithodoros) [21,41,42], to date, there is no confirmation of these ticks being vectors of TBPs or cause of clinical cases in dogs from CAC, despite the reports of E. canis in Amblyomma ovale in Yucatán and Rickettsia sp. in Ixodes affinis [21,43]. In the case of the causative agent of Q fever, Coxiella burnetii (formerly Rickettsia burnetii), little is known about its epidemiology and distribution within the CAC.…”

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.
