  abstract: Three populations of canines (owned dogs brought to
  abstract: veterinary clinics, dogs from a dog pound, and coyotes) were
  abstract: tested for the prevalence of Ehrlichia spp. antibodies.
  abstract: Sero-prevalence to Ehrlichia ranged from 20.8% among clinic
  abstract: dogs to 84.6% and 62.3% among pound dogs and coyotes,
  abstract: respectively. Ehrlichia seroprevalence among clinic dogs was
  abstract: positively associated with increased age, occupation as guard
  abstract: dogs or hunting dogs, being kept outside the majority of the
  abstract: time, and a history of travel. Unfed, adult Rhipicephalus
  abstract: sanguineus males and females were found to have a mean
  abstract: exchangeable water mass of almost 40% of their total body
  abstract: water, which approached 70% among hydrated specimens.
  abstract: Comparisons to Amblyomma americanum ticks revealed that R.
  abstract: sanguineus is significantly more tolerant of dry
  abstract: environments. Unfed R. sanguitieus adults were able to
  abstract: survive over a period of 7-8 months when released into a lawn
  abstract: environment in late fall in central Texas. Examination of
  abstract: several ticks during the winter revealed that the brown dog
  abstract: tick appears to overwinter by either becoming quiescent or
  abstract: going into a facultative diapause. Host-seeking among the
  abstract: fall cohort of R. sanguineus adults was found to be primarily
  abstract: dependent on temperature and daylength. Host seeking among
  abstract: ticks released in May appeared to be dependent primarily on
  abstract: just temperature. Daily host-seeking does not appear to be
  abstract: overly affected by age. Seasonal host-seeking behavior and
  abstract: development appear to be timed so that the following stage
  abstract: will have the greatest chance of surviving to find a host.
  abstract: The development of R. sanguineus eggs, larvae, nymphs and
  abstract: adults in a lawn environment appears to be dependent on
  abstract: temperature. Development and molting appear to slow during
  abstract: times of cold weather and increase as temperatures increase.
  abstract: The ability of the brown dog tick to overwinter in lawn
  abstract: environments coupled with its tolerance of the relatively
  abstract: xeric conditions found around residential premises, and
  abstract: capacity to complete its life cycle in a short period of time
  abstract: provide a rationale for the rapid establishment of large
  abstract: populations of this tick. Large populations can, in turn,
  abstract: increase the risk of transmission of pathogens.
