Erythromycin resistance in Borrelia burgdorferi.
Susceptibility testing of laboratory strains and clinical isolates of Borrelia burgdorferi indicates that resistance to erythromycin is present in them. Evaluation of the MICs, minimal bactericidal concentrations, and kinetics of bacterial killing of erythromycin suggests that this resistance is increased by preexposure to the antibiotic, is dependent on inoculum size, and may be the result of ...
متن کاملaadA confers streptomycin resistance in Borrelia burgdorferi.
To enhance genetic manipulation of the Lyme disease spirochete Borrelia burgdorferi, we assayed the aadA gene for the ability to confer resistance to the antibiotics spectinomycin and streptomycin. Using the previously described pBSV2 as a backbone, a shuttle vector, termed pKFSS1, which carries the aadA open reading frame fused to the B. burgdorferi flgB promoter was constructed. The hybrid fl...
متن کاملChemotaxis in Borrelia burgdorferi.
Borrelia burgdorferi is a motile spirochete which has been identified as the causative microorganism in Lyme disease. The physiological functions which govern the motility of this organism have not been elucidated. In this study, we found that motility of B. burgdorferi required an environment similar to interstitial fluid (e.g., pH 7.6 and 0.15 M NaCl). Several methods were used to detect and ...
متن کاملMutations conferring aminoglycoside and spectinomycin resistance in Borrelia burgdorferi.
We have isolated and characterized in vitro mutants of the Lyme disease agent Borrelia burgdorferi that are resistant to spectinomycin, kanamycin, gentamicin, or streptomycin, antibiotics that target the small subunit of the ribosome. 16S rRNA mutations A1185G and C1186U, homologous to Escherichia coli nucleotides A1191 and C1192, conferred >2,200-fold and 1,300-fold resistance to spectinomycin...
متن کاملComparative in vitro activities of clarithromycin, azithromycin, and erythromycin against Borrelia burgdorferi.
The in vitro activities of the macrolide antibiotics clarithromycin, 14-hydroxy-clarithromycin, azithromycin, and erythromycin against 19 isolates of Borrelia burgdorferi were investigated. MICs ranged from 0.003 to 0.03 microgram of clarithromycin per ml, 0.007 to 0.03 microgram of 14-hydroxyclarithromycin per ml, 0.003 to 0.03 microgram of azithromycin per ml, and 0.007 to 0.06 microgram of e...
