DNA and protein analyses of tick-derived isolates of Borrelia burgdorferi from California.
Nine isolates of Borrelia burgdorferi from ixodid ticks collected in northern California were characterized. Restriction endonuclease analysis, pulsed-field gel electrophoresis, and Western blot (immunoblot) analysis were used in this study. Four isolates were very similar to each other. The others shared some similarities but were classified as having unique genotypes. A strain from an Ixodes neotomae tick displayed the greatest genetic and antigenic diversity when compared to the isolates collected from Ixodes pacificus ticks. A computerized library based on DNA banding patterns of the isolates by restriction enzyme analysis is also reported. This library was created by using a scanning laser densitometer.
