Spotted-fever group Rickettsia in Dermacentor variabilis, Maryland

Emerg Infect Dis. 2004 Aug;10(8):1478-81. doi: 10.3201/eid1008.030882.

Abstract

Three-hundred ninety-two adult Dermacentor variabilis were collected from six Maryland counties during the spring, summer, and fall of 2002. Infection prevalence for spotted fever group Rickettsia was 3.8%, as determined by polymerase chain reaction. Single strand conformational polymorphism (SSCP) analysis followed by sequencing indicated that all infections represented a single rickettsial taxon, Rickettsia montanensis.
