Furthermore, they assert that infection prevalence in these ticks removed from animal hosts would likely be different from that of questing nymphs that are more likely to infect humans, further supporting our argument for the incompatibility of contrasting these two datasets, ours and the one in Williamson et al. affirm that “tick stage was not reported” for our collections, but this information is addressed extensively in page 12, paragraph 2, where collected adult ticks are described. It is highly possible that infection levels on non-human hosts differ from infection levels detected in humans, thus making both datasets not comparable.Īlso, Norris et al. report does not include any ticks recovered from humans. burgdorferi infection levels in ticks exclusively found in non-human-hosts or questing on vegetation. Contrary to what Norris and collaborators wrongly state in their letter, our paper reported B. study were obtained from humans in a passive surveillance setting, we do not consider a comparison of Williamson et al. , to question our findings is based on data obtained by Williamson et al. burgdorferi infection does occur in Texas ( ). scapularis collected from non-human mammal hosts, although they do concur that B. burgdorferi infection that we detected on I.

scapularis in Southern US, where the incidence of LD in humans is very low. burgdorferi and its interaction with the competent vector I. These efforts will serve to increase our knowledge of the ecology of B. The major motivation of this study was the need to generate a current distribution model for this tick vector, together with future distribution models that forecast any changes under different climate change scenarios. scapularis in the Texas-Mexico transboundary region, based on present predictions of suitable habitat, as well as forecasting to year 2050. consists of the potential impact of climate change in the distribution model of the tick vector I. The most relevant issue addressed by Feria-Arroyo et al. This allowed us to state that northeastern Mexico meets ecological criteria to be considered endemic for LD. scapularis from wild mammals in forest zones at an altitude of 1600–2670 meters above the sea level in the Mexican state of Nuevo León. In addition, members of our international research group collected nymph and adult I. failed to relate our collective findings based on eco-epidemiological data documenting a continuum in the pathogenic landscape of LD in the Texas-Mexico transboundary region. scapularis collected in Texas and Mexico, but seem to question the tick infection rates reported. First and foremost, perspectives like the one presented in our publication can help address the gap in knowledge of Lyme disease (LD) considering that its geographical area is expected to spread in the coming years. burgdorferi tick infection rates in Texas and northeastern Mexico. that our intergenic spacer (IGS) data for Borrelia burgdorferi sensu stricto sequences does not support the claim of B. We begin addressing the criticism expressed by Norris et al.
