Résumé / Abstract

Results of a survey for ixodid ticks and/or serum antibodies to Borrelia burgdorferi from 14 species of small to large mammals from eastern coastal areas of the United States are presented. Most samples were obtained from July 1987 through June 1989 (excluding December-March) at 3 locales: Assateague Is. National Seashore, Worcester Co., MD., and Accomack Co., VA. (38° 05' N 75° 10' W). and Cape Hatteras National Seashore, Dare Co., NC (35° 30' N 76° 35' W). Hosts sampled included opossums (Didelphis virginiana). least shrews (Cryplotis parva). gray foxes (Urocyon cinercoargenleus). red foxes (Vulpes vulpes), raccoons (Procyon lotor). feral cats (Felis sylvestris), feral horses (Equtis cabollus), sika deer (Cervus nippon). rice rats (Oryzomys palustris), white-footed mice (Peromyscus leucopus). meadow voles (Microtus pennsylvanicus), house mice (Mus musculus). norway rats (Rattus norvegicus) and jumping mice (Zapus hudsonius). An indirect fluorescent antibody test was used for testing sera from opossums, raccoons, and feral cats; enzyme-linked immunosorbent assays were used for sera from foxes, horses, deer, and house and white-footed mice. Antibodies to B. burgdorferi were found in all species tested from each locale. Seasonal data reinforce the contention that P. lcucopus is a suitable sentinel species for B. burgdorferi. Ticks on hosts included Ixodes scapularis Say. I. texanus Banks. Dermacentor variabilis (Say). D. albipictus (Pack-ard), and Amblyomma americanum (L.). Males comprised 0-22 and 60-81% of Ixodes sp. and Amblyomma-Dermacentor adults collected from hosts, respectively. All stages of A. america adult D. variabilis. and larval I. scapalaris were collected from vegetation. The highest seropositivity rate (67%) was recorded for 45 P. leucopus at Assateague during July 1 mo. after peak nymphal I. scapularis intensity, Borrelia burgdorferi was isolated from 6 nymphal and 12 female I. scapularis collected from P. lcucopus and C nippon, respectively, on Assateague.
