          Abstract

          Introduction

          Mycobacterium avium complex (MAC) and Mycobacterium abscessus are a group of nontuberculous mycobacteria (NTM) that have been described as human pathogens. Their ability to develop biofilms in tissues and medical devices is one of the most important pathogenicity factors, with important implications in diagnosis and treatment. Macrolides are usually considered one of the bases of this treatment.

          Methods

          Here we have studied the biofilm prevention concentration (BPC) of 16 strains (n=16) with clarithromycin to avoid the biofilm development by these NTM.

          Results

          In this study, all M. abscessus strains have similar BPC, while MAC strains showed different values. For MAC the concentrations ranged between 1-16 mg/L, while for M. abscessus the concentration was 32 mg/L for all strains except one that was 64 mg/L.

          Conclusions

          These results open the possibility of using macrolides for the prevention of biofilm development in patients with a risk of developing NTM disease.

          Introducción

          Mycobacterium avium complex (MAC) y Mycobacterium abscessus son un grupo de micobacterias no tuberculosas (NTM) que han sido descritas como patógenos humanos. Entre los factores de patogenicidad más importantes se encuentra su capacidad para desarrollar biopelículas en tejidos y dispositivos médicos, con importantes implicaciones en el diagnóstico y tratamiento. Los macrólidos suelen considerarse una de las bases de este tratamiento.

          Métodos

          En este estudio hemos estudiado la concentración para la prevención de biopelículas (BPC) de 16 cepas (n=16) con claritromicina para varias de estas NTM.

          Resultados

          Todas las cepas de M. abscessus tienen BPC similares, mientras que las cepas de MAC mostraron valores diferentes. Para MAC las concentraciones presentaron un rango entre 1-16 mg/L, mientras que para M. abscessus la concentración fue de 32 mg/L para todas las cepas excepto una, que fue de 64 mg/L.

          Conclusiones

          Estos resultados abren la posibilidad de utilizar macrólidos para la prevención del desarrollo de biopelículas en pacientes con riesgo de desarrollar enfermedad por NTM.

            Proposal that Mycobacterium massiliense and Mycobacterium bolletii be united and reclassified as Mycobacterium abscessus subsp. bolletii comb. nov., designation of Mycobacterium abscessus subsp. abscessus subsp. nov. and emended description of Mycobacterium abscessus.

            The names 'Mycobacterium abscessus subsp. abscessus' and 'Mycobacterium abscessus subsp. massiliense', proposed by Leao et al. (2009, J Clin Microbiol 47, 2691-2698), cannot be validly published. The purpose of this report is to provide a description in accordance with the Rules of the Bacteriological Code (1990 Revision). Moreover, the proposal of the name 'Mycobacterium abscessus subsp. massiliense' is contrary to Rule 38 and the correct name of this taxon, at the rank of subspecies, is Mycobacterium abscessus subsp. bolletii comb. nov. A description of Mycobacterium abscessus subsp. abscessus subsp. nov. and an emended description of Mycobacterium abscessus are also given.
