“…En este estudio se encontró que el 92% de los VCB estaban parasitados con garrapatas, aunque las especies de garrapatas identificadas en este estudio ya habían sido reportadas parasitando VCB en México y también han demostrado estar infectadas con los géneros Rickettsia y Ehrlichia (Ojeda-Chi et al, 2019;Sánchez-Montes et al, 2021). Rhipicephalus microplus fue la garrapata con mayor frecuencia (29.0%) e intensidad (25.2) en los VCB, esta especie de garrapata ha sido reportada parasitando principalmente a los bovinos de la misma región (Rodríguez-Vivas et al, 2016).…”

Background: Louse-fly (Lipoptena spp.) and ticks are blood-sucking ectoparasites of domestic and wild animals and accidentally of humans. Globally, there is little information on the medical importance of these ectoparasites, but there are studies that suggest that these ectoparasites might be involved in the transmission of pathogens. In Mexico, both ectoparasites have been reported parasitizing white-tailed deer (WTD, Odocoileus virginianus). Objective: To estimate the prevalence and intensity of Lipoptena spp. and ticks in WTD and its possible implication of louse-flies as a vector of Anaplasma spp. in Southeastern Mexico. Methodology: 25 WTD were inspected for their louse-flies and ticks. Pools of louse-flies were tested by a nested polymerase chain reaction (PCR) to identify the presence of a fragment of the 16S-rDNA gene of Anaplasma spp. Results: All louse-fly (96 specimens) were identified as Lipoptena mazamae and 348 ticks of the genera Amblyomma, Ixodes, Rhipicephalus and Haemaphysalis were also identified. The prevalence of WTD with L. mazamae was 56% with an intensity of 6.9 flies/WTD, meanwhile the prevalence of ticks was 92% with an intensity of 15.5 ticks/WTD. Anaplasma spp. was not detected in any of the pools of flies evaluated. Implications: WTD are parasitized by ectoparasites that affect their health and can be transmitters of pathogens to wild animals, domestic animals, and humans, therefore their identification is important for the design of prevention programs. Conclusion: WTD showed high prevelances of L. mazamae and different species of ticks, being the latter with high prevalence and intensity. Molecular tests showed that louse-flies evaluated in this study were not found to be infected with Anaplasma spp.

“…Subsequently, a battery of oligonucleotides was implemented for the detection of bacterial ( Anaplasma, Borrelia, Coxiella, Ehrlichia and Rickettsia ) and protozoan ( Babesia ) pathogens 13 , in tick and the patients’ blood sample. The PCR was performed in a final volume of 25 μL, using 12.5 μL of GoTaq of Promega, 1 μL of each oligonucleotide (2 μM), 8.5 μL of DNA (300 ng) and 2 μL of nuclease-free water.…”

In this study, we report the presence of a female Amblyomma americanum tick attached to a former resident of the East Coast of the United States who moved to Mexico city. The amplification and sequencing of gene fragments of the 16S-rDNA and cytochrome c oxidase subunit 1 corroborated the identification of the species of the tick. Additionally, the presence of DNA of Rickettsia amblyommatis was confirmed. This work is the first report of an exotic tick of the genus Amblyomma in a traveler from the US to Mexico and represents the second record of an imported tick attached to humans in Mexico.

“…Across México, rickettsiae pathogens have been described in vectors and hosts in northern Baja California, Sonora, Chihuahua [19], Campeche [20,21], Yucatán [22], Tabasco [23], Veracruz [21,24], Tamaulipas [24][25][26], and Coahuila [4,12,27]. Ongoing outbreaks of RMSF since 2008, with high fatality rates, in northwestern regions of México have been much of the focused surveillance, with human disease also reported from adjacent indigenous communities of Arizona [28][29][30][31][32].…”

Of the documented tick-borne diseases infecting humans in México, Rocky Mountain spotted fever (RMSF), caused by the Gram-negative bacterium Rickettsia rickettsii, is responsible for most fatalities. Given recent evidence of brown dog tick, Rhipicephalus sanguineus s.l., as an emerging vector of human RMSF, we aimed to evaluate dogs and their ticks for rickettsiae infections as an initial step in assessing the establishment of this pathosystem in a poorly studied region of northeastern México while evaluating the use of dogs as sentinels for transmission/human disease risk. We sampled owned dogs living in six disadvantaged neighborhoods of Reynosa, northeastern México to collect whole blood and ticks. Of 168 dogs assessed, tick infestation prevalence was 53%, composed of exclusively Rh. sanguineus s. l. (n = 2170 ticks). Using PCR and sequencing, we identified an overall rickettsiae infection prevalence of 4.1% (n = 12/292) in ticks, in which eight dogs harbored at least one infected tick. Rickettsiae infections included Rickettsia amblyommatis and Rickettsia parkeri, both of which are emerging human pathogens, as well as Candidatus Rickettsia andeanae. This is the first documentation of pathogenic Rickettsia species in Rh. sanguineus s.l. collected from dogs from northeastern México. Domestic dog infestation with Rickettsia-infected ticks indicates ongoing transmission; thus, humans are at risk for exposure, and this underscores the importance of public and veterinary health surveillance for these pathogens.
