risk of human exposure to vector ticks (acari: ixodidae) in a heavily used recreational area in northern california.	the risk of humans encountering vector ticks along hiking trails or in picnic grounds in a lyme disease-endemic area was evaluated in a multipurpose recreational area (tilden regional park) in the populous san francisco bay region of california. four hillside hiking trails (two high-use, two low-use) were sampled by dragging and walking through low vegetation biweekly for one year; four heavily used picnic areas were sampled concurrently by dragging. adults of three human-biting ticks were enume ...	1996	8780455
detection and characterization of borrelia bissettii in rodents from the central california coast.	this is the first report of borrelia burgdorferi sensu lato in rodents from san luis obispo county, with most isolates obtained from a previously unreported host, neotoma lepida thomas. b. burgdorferi sensu lato was identified in seven rodent species, including the california vole, microtus californicus peale; dusky-footed woodrat, neotoma fuscipes baird; desert woodrat, neotoma lepida thomas; brush mouse, peromyscus boylii baird; california mouse, peromyscus californicus gambel; deer mouse, per ...	2004	15311469
genetic diversity of borrelia burgdorferi and detection of b. bissettii-like dna in serum of north-coastal california residents.	in north america, lyme borreliosis (lb) is a tick-borne disease caused by infection with the spirochete borrelia burgdorferi. we studied the genetic diversity of lb spirochetes in north-coastal california residents. spirochete dna was detected in 23.7% (27/114) of the study subjects using a pcr protocol optimized for increased sensitivity in human sera. californians were most commonly infected with b. burgdorferi ospc genotype a, a globally widespread spirochete associated with high virulence in ...	2010	21177909
