“…Eggs are laid within two weeks following female engorgement, and larvae hatch about four weeks later. The peak in larval abundance may occur from late July to September (Bishopp and Hixson 1936;Semtner and Hair 1973); in coastal areas of Texas, Teel et al (1988; observed greatest numbers of larvae on meadowlarks during November to January. Ground-foraging birds (e.g., meadowlarks and bobwhite quail) and small mammals are important hosts, and larvae attach to the head and neck regions (Hixson 1940).…”

“…Its predilection for birds is one reason we see this species in Canada (Scott et al 2001). In the Gulf States, adults appear early in spring and may be present on large mammals until late summer, though their peak in abundance is usually June to early July (Hixson 1940;Semtner and Hair 1973); their abundance may remain high until September in some areas (Bishopp and Hixson 1936). Eggs are laid within two weeks following female engorgement, and larvae hatch about four weeks later.…”

“…Ground-foraging birds (e.g., meadowlarks and bobwhite quail) and small mammals are important hosts, and larvae attach to the head and neck regions (Hixson 1940). In some parts of its range, nymphs may be collected in every month of the year (Hixson 1940), while elsewhere, the season may be more limited, with peak abundance in late summer or early autumn (Bishopp and Hixson 1936;Semtner and Hair 1973) or during December or February to March (Teel et al 1988;.…”

“…A. cajennense is also a tropical tick species sometimes reported in the southern United States; it has not spread as widely in North America as has A. maculatum. The latter was once thought not to be endemic beyond a range of about 200 miles from the Gulf Coast, whereas it now is endemic quite far inland, including northeastern Oklahoma and southeastern Kansas (58,60). In Brazil, A. cajennense ticks found on dogs were usually larvae or nymphs; favored hosts of the adults were equids (52).…”

American Canine Hepatozoonosis

American canine hepatozoonosis (ACH) is a tick-borne disease that is spreading in the southeastern and south-central United States. Characterized by marked leukocytosis and periosteal bone proliferation, ACH is very debilitating and often fatal. Dogs acquire infection by ingesting nymphal or adult Gulf Coast ticks (Amblyomma maculatum) that, in a previous life stage, ingested the parasite in a blood meal taken from some vertebrate intermediate host. ACH is caused by the apicomplexan Hepatozoon americanum and has been differentiated from Old World canine hepatozoonosis caused by H. canis. Unlike H. canis, which is transmitted by the ubiquitous brown dog tick (Rhipicephalus sanguineus), H. americanum is essentially an accidental parasite of dogs, for which Gulf Coast ticks are not favored hosts. The geographic portrait of the disease parallels the known distribution of the Gulf Coast tick, which has expanded in recent years. Thus, the endemic cycle of H. americanum involves A. maculatum as definitive host and some vertebrate intermediate host(s) yet to be identified. Although coyotes (Canis latrans) are known to be infected, it is not known how important this host is in maintaining the endemic cycle. This review covers the biology of the parasite and of the tick that transmits it and contrasts ACH with classical canine hepatozoonosis. Clinical aspects of the disease are discussed, including diagnosis and treatment, and puzzling epidemiologic issues are examined. Brief consideration is given to the potential for ACH to be used as a model for study of angiogenesis and of hypertrophic osteoarthropathy

“…There are also occasional reports of the species from inland and northern states (Goddard & Norment 1983;Snoddy & Cooney 1984), and a well-established population occurs in Oklahoma and Kansas (Semtner & Hair 1973). Recently, the GCT has emerged as an arthropod of increasing medical and veterinary importance, being known to transmit Rickettsia parkeri to humans, causing a condition sometimes called "American boutonneuse fever" (Goddard 2004;Paddock et al 2004), the protozoan Hepatozoon americanum to dogs (Ewing & Panciera 2003), and potentially the agent of heartwater, Ehrlichia ruminantium, to ruminants (Uilenberg et al 1982).…”

During August of 2008 and 2009, observations were made on the questing heights, behaviors, and spatial distribution of adult Gulf Coast ticks, Amblyomma maculatum, in a plot near Gautier, Jackson County, Mississippi, U.S.A. Ticks were not evenly distributed in the plot, being found mostly on torpedograss and/or wiregrass along and in a small dirt field road. Adult ticks were visually observed questing on three different plants: torpedograss, Panicum repens, wiregrass, Aristida stricta, and Johnsongrass, Sorghum halepense, all but the last of which have small-diameter stems and thin, pointed leaves. Ticks were located at or near the tips of the plants (2-tail binomial probability, p = 0.0074). Observed questing heights ranged from 20-75 cm, with an average of 36 cm. Nine of 15 ticks (60%) seen questing were oriented head upward, while 6 (40%) were headdown. Limited mark-release-recapture observations were made in the study site, using ticks collected from the field road. Of 27 ticks marked and released, 15 were recaptured in three samples spanning a 24-d period. Of these, 5 had moved closer to the dirt road where they were originally captured and 2 farther away.
