The bacterial membranes in at least the B31, NL303 and N40 strains of B. burgdorferi do not contain lipopolysaccharide, which is extremely atypical for Gram negative bacteria; instead, the membranes contain glycolipids.
As membranas bacterianas de polo menos as cepas B31, NL303 e N40 de B. burgdorferi non conteñen lipopolisacárido, o cal é moi atípico en bacterias gramnegativas; e no seu lugar as membranas conteñen glicolípidos.
