Conclusion: Antibiotics have varying effects on the different morphological forms of B. burgdorferi. Amoxicillin reduced spirochetal forms by ∼85%% and round body forms by ∼68%, while treatment with metronidazole led to reduction of spirochetal structures by ∼90% and round body forms by ∼80%. Results: Doxycycline reduced spirochetal structures ∼90% but increased the number of round body forms about twofold. Persistence of viable organisms in round body forms and biofilm-like colonies may explain treatment failure and persistent symptoms following antibiotic therapy of Lyme disease. Antibiotics have varying effects on the different morphological forms of B. burgdorferi. When quantitative effects on biofilm-like colonies were evaluated, the five antibiotics reduced formation of these colonies by only 30%%. In terms of qualitative effects, only tinidazole reduced viable organisms by ∼90%. Tigecycline and tinidazole treatment reduced both spirochetal and round body forms by ∼80%%.

  • Our in-vitro methodology will. The study also describes novel microscopic viability determination methods to assess three morphological forms of B. burgdorferi (spirochetes, round bodies, and biofilm-like colonies), and the methods were used to evaluate antibiotic susceptibility of the different morphological forms of this complex organism. To evaluate in-vitro antibiotic sensitivity of spirochete and round body morphological forms, two strains of B. burgdorferi (B31 and S) were incubated for 72 hours with different antibiotics at concentrations above the calculated MIC and MBC. Persistence of viable organisms in round body forms and biofilm-like colonies . Conclusion: Antibiotics have varying effects on the different morphological forms of B. burgdorferi. Studies have suggested that resistance and recurrence of Lyme disease might be due to formation of different morphological forms of B. 5 ก.ค. Our in-vitro methodology will facilitate the design of experiments that mimic tissue-based in-vivo conditions in order to optimize the antibiotic treatment of Lyme disease. May 03, · The study also describes novel microscopic viability determination methods to assess three morphological forms of B. burgdorferi (spirochetes, round bodies, and biofilm-like colonies), and the methods were used to evaluate antibiotic susceptibility of the different morphological forms of this complex organism. Although antibiotic therapy is usually effective early in the disease, relapse may occur when administration of antibiotics is discontinued. Evaluation of in-vitro antibiotic susceptibility of different morphological forms of. Borrelia burgdorferi. Background: Lyme disease is a tick-borne illness caused by the spirochete Borrelia burgdorferi. When quantitative effects on biofilm-like colonies were evaluated, the five antibiotics reduced. Tigecycline and tinidazole treatment reduced both spirochetal and round body forms by ∼80%%. Treatment with these higher concentrations showed that. Antibiotic sensitivity was evaluated using the direct cell counting and dark field morphological evaluation methods (Figure 1). Studies have suggested that resistance and recurrence of Lyme disease might be due to formation of different morphological forms of B. Antibiotics have varying effects on the different morphological forms of B. burgdorferi, and persistence of viable organisms in round body.
