“…They estimated larval densities for south Texas of approximately 200,000 per hectare; these simulations also estimated somewhat less than 200 adult ticks per cow and no other hosts were included in that model. The influence of landscape features on the annual variation of host-seeking larvae determined by ecological factors was also documented in Puerto Rico (Urdaz-Rodríguez et al 2012).…”

White-tailed deer (Odocoileus virginianus) are a host for cattle fever ticks (Rhipicephalus (Boophilus) sp.), which are vectors of the pathogens causing bovine babesiosis and anaplasmosis in cattle. Tick eradication efforts focused on cattle along the U.S.-Mexico border are high priority and the potential role of white-tailed deer in compromising these efforts is of great concern. We developed a spatially-explicit,

“…Most dwarf goats infested with Anaplasma spp come from areas along the Bandama River and Kan River. The surroundings of these rivers represent a microclimate in which moisture is maintained for the survival of certain vectors responsible for anaplasmosis (Urdaz-Rodriguez et al, 2012). This would explain the many cases of goats infested in these places.…”

geographical areas. This makes the diagnosis difficult and their prevalence often underestimated (Ohashi et al., 2005). They are often the cause of several weeks of inactivity, sometimes leading to considerable losses in production and fertility on farms (Sharff, 2010; Moses and Phillip, 2013). Material and methods:-Study zone This study is a cross-sectional study. It was conducted from December 2015 to September 2016 on goats from the Béoumi sub-prefecture in central Côte d'Ivoire, in humid West Africa, between the tropic of cancer and the equator (FAO, 2005). This sub-prefecture covers an area of 1780 km 2 for 73475 inhabitants (INS, 2014). It is limited to the north by the sub-prefecture of Bodokro, to the south by the department of Sakassou, to the east by the department of Bouaké, to the west by the sub-prefectures of Kounahiri and Gohitafla (Fig. 1). Relief consists of a set of trays. Climate is of Baoulean type, characterized by a dry season and a wet season, with rainfall between 1200 and 1600 mm / year (FAO, 2005). Two rivers irrigate the sub-prefecture namely the Bandama River and the Kan River which is its tributary. This site was chosen because of the presence of a large number of goat farmers. Samples collection Study was conducted on a total of 270 dwarf goats coming from two different zones (Zone A and Zone B). These animals were divided into two groups. The first group including 135 dwarf goats were come from all the localities located at more than 15 km of the rivers (Zone A). This area is characterized by savannah which is covered with grass and shrubs. This herbaceous carpet is abundant during the rainy seasons but is destroyed by the fires in the dry season. The second group including also 135 goats were come from all the zones located close to the rivers Bandama and Kan between 0.5 and 1 km (zone B). These two rivers do not dry during the dry season; their bank promotes the development of vegetation likely to host some vectors of Anaplasma. Two types of sample were collected. The first type (270 blood sample) was taken out on the level of the jugular vein for the realization of the serological examinations (ELISA). The second type (270 blood samples) was taken out on the level of auricular vein for the parasitological examinations (blood Smears).

“…Giant reed may also be creating a localized climatic refuge for CFT when conditions in the upland habitat are not favorable for survival. As giant reed declines, lower ET rates, increased ground temperatures, and lower humidity levels are expected in these riparian habitats and these conditions are known to reduce the survival of larval and adult CFT ( 41 – 45 ). Giant reed also indirectly impacts the CFTEP by reducing visibility in the PQZ along the Rio Grande.…”

Transboundary zoonotic diseases, several of which are vector borne, can maintain a dynamic focus and have pathogens circulating in geographic regions encircling multiple geopolitical boundaries. Global change is intensifying transboundary problems, including the spatial variation of the risk and incidence of zoonotic diseases. The complexity of these challenges can be greater in areas where rivers delineate international boundaries and encompass transitions between ecozones. The Rio Grande serves as a natural border between the US State of Texas and the Mexican States of Chihuahua, Coahuila, Nuevo León, and Tamaulipas. Not only do millions of people live in this transboundary region, but also a substantial amount of goods and people pass through it everyday. Moreover, it occurs over a region that functions as a corridor for animal migrations, and thus links the Neotropic and Nearctic biogeographic zones, with the latter being a known foci of zoonotic diseases. However, the pathogenic landscape of important zoonotic diseases in the south Texas–Mexico transboundary region remains to be fully understood. An international perspective on the interplay between disease systems, ecosystem processes, land use, and human behaviors is applied here to analyze landscape and spatial features of Venezuelan equine encephalitis, Hantavirus disease, Lyme Borreliosis, Leptospirosis, Bartonellosis, Chagas disease, human Babesiosis, and Leishmaniasis. Surveillance systems following the One Health approach with a regional perspective will help identifying opportunities to mitigate the health burden of those diseases on human and animal populations. It is proposed that the Mexico–US border along the Rio Grande region be viewed as a continuum landscape where zoonotic pathogens circulate regardless of national borders.
