A Borrelia burgdorferi chromosomal gene encodes a 30-kDa antigen (P30) that has considerable homology with periplasmic substrate-binding proteins of Gram-negative bacteria, and is recognized by antibodies in sera from a subset of patients with Lyme disease and from B. burgdorferi-infected mice. The p30 gene is 801 nucleotides in length and P30 contains 267 amino acids, with a predicted molecular mass of 30 kDa. The P30 amino acid region 36-258 has homology to conserved domains of the oligopeptide permease A of Gram-negative bacteria. Immunofluorescence studies using murine anti-P30 serum suggest that P30 is on the outer surface of B. burgdorferi. P30 expression could be detected in representatives of all 3 subspecies of B. burgdorferi sensu lato, but not in all of the tested strains. Antibodies to P30 were detected in sera of 18 out of 82 patients (22%) with Lyme disease, including individuals with early- or late-stage infection. Although antibodies to P30 are present in the sera of C3H/HeN mice infected with B. burgdorferi for at least 90 days, immunization with recombinant P30 does not protect mice from infection. We conclude that P30 is a putative substrate-binding protein of B. burgdorferi and is immunologically recognized in human and murine Lyme borreliosis.

UI MeSH Term Description Entries
D008193 Lyme Disease An infectious disease caused by a spirochete, BORRELIA BURGDORFERI, which is transmitted chiefly by Ixodes dammini (see IXODES) and pacificus ticks in the United States and Ixodes ricinis (see IXODES) in Europe. It is a disease with early and late cutaneous manifestations plus involvement of the nervous system, heart, eye, and joints in variable combinations. The disease was formerly known as Lyme arthritis and first discovered at Old Lyme, Connecticut.
