“…Several studies have compared the relative abundance of ticks among specific habitats, terrains, or residential sites (Carey et al 1980, Stafford et al 1998, Stafford and Magnarelli 1993, or reported tick prevalence on domestic and wild mammals, or characterized the species of ticks found naturally attached to a wide range of hosts including humans (Anderson and Magnarelli 1980, Barker et al 2004, Carey et al 1980, Falco and Fish 1988, Felz et al 1996, Foley et al 1999, Goddard 1989, Greiner et al 1984, Hall et al 1991, Koch 1982, Kollars and Ladine 1999. These studies, however, covered small geographic areas and used a wide variety of techniques to measure tick abundance.…”

“…Mapping distribution based on direct field observations, however, is time consuming and requires large-scale organization (Daniel and Dusbabek 1994). Limited areas are studied using techniques such as flagging, walking, trapping, and collecting from several wild and domestic hosts including humans, to report tick abundance (Anderson and Magnarelli 1980, Barker et al 2004, Carey et al 1980, Falco and Fish 1988, Felz et al 1996, Foley et al 1999, Goddard 1989, Greiner et al 1984, Hall et al 1991, Kollars and Ladine 1999, Stafford et al 1998, Koch 1982, Stafford and Magnarelli 1993. Because of the diversity in measurement techniques, the findings from published reports cannot always be directly compared across the nation.…”

Knowledge of the geographic range and seasonal activity of vector ticks is important for determining which people or animals are at risk of acquiring tick-borne infections. Several time-consuming methods requiring large-scale organization are used to map geographic and seasonal variations in tick distribution. A cost-effective, complementary approach to study tick distribution using a large nation-wide veterinary database is described in this paper. Prevalence of canine tick infestation in 40 states was estimated by analyzing electronic medical records of more than 8 million dog visits to Banfield veterinary hospitals in 2002-2004. Prevalence was defined as the proportion of dog visits in which tick infestation was recorded, and was expressed per 10,000 dog visits with 95% confidence intervals (CI). The overall prevalence (CI) of tick infestation was 52 (51, 53) dogs per 10,000 dog visits. Among states, Oklahoma (249 [229, 271) dogs with ticks per 10,000 dog-visits), Arkansas (242 [213, 274]), Connecticut (136 [119, 155]), West Virginia (130 [105, 161]), and Rhode Island (122 [97, 154]) ranked highest in prevalence of canine tick infestation. Overall prevalence peaked from May through July, although monthly prevalence varied by geographic region. In multiple logistic regression, younger dogs, male dogs, and sexually intact dogs, were at increased risk of tick infestation. Toy breeds were least likely to be infested, but no linear pattern of risk was evident with body weight. Identified risk factors should enable veterinarians to prevent tick infestation in pet dogs although differences in risk of tick infestation may be related to outdoor activity of dogs. Feasibility of collecting information for surveillance of vectors ticks on a national level using this large, electronic veterinary database is discussed.

“…There have been several surveys on wild pig parasites (Coombs and Springer, 1974;Foreyt et al, 1975;Prestwood et al, 1975;Smith et al, 1982;Greiner et al, 1984;Pence et al, 1988), but only a few studies on wild pig blood biochemistry (Williamson and Pelton, 1975;Wolkers et al, 1993Wolkers et al, , 1994b. Except for some information on packed cell volume (PCV) and hemoglobin concentration (HB), there are no known values reported for whole blood parameters from feral pigs.…”

In the summers of 1996 and 1997, 60 wild pigs (Sus scrofa) were necropsied from three sites in south Texas (USA) to test the hypothesis that serum and whole blood parameters vary significantly (P Յ 0.05) with the prevalence and intensity of parasites infecting wild pigs. We found ten parasite species: five nematodes (Metastrongylus salmi, Metastrongylus pudentotectus, Stephanurus dentatus, Oesophagostomum dentatum, and Physocephalus sexalatus); four ixodid ticks (Amblyomma cajennense, Amblyomma maculatum, Amblyomma americanum, and Dermacentor variabilis); and one trematode (Fascioloides magna). Among juvenile pigs, the intensity of the four species of ticks, collectively, was negatively correlated (P Յ 0.05) with whole blood principal component number one (PC-1); this factor was positively associated with lymphocytes and eosinophils. Lungworm intensity (Metastrongylus spp.) among adult pigs was negatively correlated (P Յ 0.05) with whole blood PC-2; this factor was negatively associated with segmented neutrophils and monocytes. There were no significant correlations found between parasite prevalences and either serum or whole blood principal component factors. The correlations observed between parasite intensities and serum and whole blood parameters generally were weak. Thus, we found no strong evidence that serum and whole blood parameters provided good predictive information on parasite infections in wild pigs for most practical management decisions.

“…Tick surveys in Georgia (Hanson and Karstad 1959) and Florida (Greiner et al 1984;Allan et al 2001) Amblyommma mixtum and A. tenellum are reported by these names on feral swine here for the first time, but previously, these two species names were treated as synonyms of A. cajennense until their recent resurrections (Nava et al 2014 a, b). Geographically, both species occur in the U.S.A. only in South Texas, and the range of each also includes much of east-central Mexico, but A. mixtum further occupies southern Mexico, all of Central America, and northeastern coastal South America as far south as Ecuador (Estrada-Peña et al 2014;Rivera-Páez et al 2016), whereas the singular, disjunct, and southern-most record for A. tenellum is from Honduras (Becklund 1959).…”

We collected ticks from feral swine, Sus scrofa L., during 1-3 September 2015, in pastures known to be infested by southern cattle ticks, Rhipicephalus (Boophilus) microplus (Canestrini), at the Laguna Atascosa National Wildlife Refuge in Cameron County, Texas, U.S.A. All 81 examined feral swine were infested by ticks, but none was infested by R. microplus. Tick species collected were Amblyomma maculatum Koch, Amblyomma mixtum Koch, Amblyomma tenellum Koch, Dermacentor halli McIntosh, and Dermaentor variabilis (Say). This is the first formal report of A. tenellum infesting feral swine.
