“…We present Borrelia species data that is differentiated into two broad categories. The first group is B. burgdorferi sensu lato (also recognized as the genus Borreliella [ 39 – 41 ]), hereafter referred to as Lyme group Borrelia , which includes the disease agent most commonly responsible for Lyme disease in the United States, B. burgdorferi sensu stricto , and B. mayonii ( 5 , 42 ). Additionally, this group includes closely related genospecies, e.g., B. americana , B. andersonii , B. bissettiae , B. californiensis , B. carolinensis , and B. kurtenbachii ( 30 , 41 – 46 ).…”
