ABSTRACT

Las medidas de bioseguridad están predestinadas a reducir el riesgo de transmisión de microorganismos a partir de fuentes de infección reconocidas o no reconocidas en clínicas dentales vinculadas con lacontaminación de los materiales, aparatos y/o instrumentos. Un microorganismo reemergente es el Mycobacterium abscessus, que es unabacteria ambiental que puede ocasionar problemas de salud muy serios, por lo que debe ser controlada y prevenida su transmisión.


Biosafety measures are designed to reduce the risk of transmission ofmicroorganisms from recognized or unrecognized sources of infectionin dental procedures associated with the contamination of materials,apparatus, and/or instruments. One reemerging microorganism isMycobacterium abscessus, which is an environmental bacterium thatcan cause serious health problems and therefore needs to be controlledand prevented.

ABSTRACT

A Mycobacterium abscessus subspécie abscessus é um pesadelo quando envolvida em infecção pulmonar que são incuráveis, a despeito do uso de antimicrobianos com atividade in vitro, caso o tratamento não inclua a ressecção cirúrgica da área afetada. É a micobactéria patogência de crescimento rápido mais frequentemente isolada de culturas de sítios pulmonares. Há um número reduzido de opções terapêuticas para o tratamento dessas infecções, e é ainda mais reduzido o número de antimicrobianos que atingem concentrações terapêuticas no compartimento intracelular, em particular no fagossomo. O número limitado de antimicrobianos disponíveis para tratamento apontam a necessidade de determinação do perfil de susceptibilidade frente a antimicrobianos isolados e em combinação, nos compartimentos intra e extracelular. Os objetivos deste estudo foram avaliar: a sensibilidade de M. abscessus estruturadas em biofilmes e presentes no interior dos macrófagos; a ocorrência de sinergismo quando da associação entre fármacos, inibidores de betalactamase e o anti-inflamatório. As combinações entre os antimicrobianos foram apenas indiferente quanto ao FIC e a atividade dos fármacos em biofilme e em macrófagos é bacteriostático


Mycobacterium abscessus subspecies abscessus is a nightmare when involved in lung infection that is incurable, despite the use of antibiotics with in vitro activity, if the treatment does not include surgical resection of the affected area. It is a MCR - rapidly growing mycobacteria pathogenic most frequently isolated from cultures of lung sites. There are a small number of therapeutic options for the treatment of such infections is further reduced and the number of drugs that reach therapeutic concentrations in the intracellular compartment, particularly in the phagosome. The limited number of antimicrobials available for treatment indicate the need for determining the susceptibility profile against antimicrobials alone and in combination, in the intra and extracellular compartments. The objectives of this study were sensitivity of MCR structured biofilms and present in macrophages, the occurrence of synergism when the association between drugs, beta-lactamase inhibitors and anti-inflammatory. Combinations of antimicrobials were just indifferent and the activity of drugs on biofilms and macrophages was bacteriostatic
