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

ABSTRACT

The article reviewed the advance and the forensic meaning of macrophage on the wound age estimation during the wound healing process in resent years. It has also been summarized the relationship between macrophages and wound age estimation on the expression of cytokines derived from macrophages, the changes of macrophage phenotypes and the development process of phagosomes in macrophages after wounding. It is suggested that some regular and characteristic changes of macrophage should be a useful mark to wound age estimation and reminds therefore further study in this field.
