Secondary Mycobacterium abscessus Infection after Debridement in Child with Dog Bite: a Case Report.

Background: In recent years, there have been increasing reports related to infection caused by Mycobacterium abscessus (MAB). As one of the most common mycobacterium iatrogenic infections, it is characterized by pulmonary infection. However, only a few reports of MAB-related skin and soft tissue infections are available.

[Relationship Between the VNTR Loci Polymorphism and MALDI-TOF MS Protein Profile Diversity in Complex].

Objective: To study the relationship between the copy numbers of repetitive units at variable number tandem repeat (VNTR) loci of complex (MTBC) with its diversity of protein profiles.

Methods: The MTBC strains were subjected to genotyping using multiple locus variable number tandem repeat analysis (MLVA). Also, the principal component analysis (PCA) was performed for bacterial protein profiles of MTBC using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS).

[Galactomannan Tests of Bronchoalveolar Lavage Fluid for Diagnosing Invasive Pulmonary Aspergillosis].

Objective: To determine the value of galactomannan (GM) in bronchoalveolar lavage fluid (BALF) for diagnosing invasive pulmonary aspergillosis.

Methods: According to the European Organization for Research and Treatment of Cancer / Invasive Fungal Infection Group (EORTC / IFICG) and the American Mycosis Research Group (MSG),and the American College of Infectious Diseases (IDSA) guidelines,295 patients with pulmonary aspergillosis (IPA) and high risk of invasive infections were divided into four groups: IPA group (42 cases),clinically diagnosed group (68 cases),suspected group (61 cases),and non-IPA group (124 cases). Their serum and BALF concentrations of GM were detected by enzyme-linked immunosorbent assay (ELISA).
