Pathogenicity Assessment of Colombian Strains of in the Invertebrate Model.

, first described in 2009, is an opportunistic pathogenic yeast that causes nosocomial outbreaks around the world, with high mortality rates associated with therapeutic failure. In this study, we evaluated the pathogenicity of 107 isolates from two cities in Colombia, associated with fungemia or colonization processes; to achieve this, we used the invertebrate model to compare pathogenicity. Our results showed that less than half of the total isolates of presented a high pathogenicity compared to the reference strain SC5314, and most of those highly pathogenic strains were from colonization processes.

Infections due to Rare Species. A Literature Review.

Infections due to rare species (other than species complex, species complex, or are barely reported. The aim of this work is to present a comprehensive literature review of all the papers describing infections due to these species referenced in the main databases (PubMed/MEDLINE, ScienceDirect, Scopus, and Google Scholar). Clinical and epidemiological data together with laboratory findings (identification and antifungal susceptibility) of each isolate were analyzed.

Differentiation of Species Complex by Tobacco Agar Obtained from Different Cigarette Brands Available in Colombia.

Aim: To evaluate the efficacy of different brands of cigarettes in the preparation of tobacco agar, for the differentiation of these related yeasts. . Tobacco agar was prepared using six brands and four varieties of cigarettes, and 125 clinical isolates previously identified by PCR and Maldi-Tof were used.

Case Series Study of Melioidosis, Colombia.

We report 7 cases of melioidosis in Colombia and comparision of 4 commercial systems for identifying Burkholderia pseudomallei. Phoenix systems were not a definitive method for identifying B. pseudomallei.

Necrotizing fasciitis caused by in an immunocompetent patient.

Mucormycosis caused by Apophysomyces variabilis is rarely reported in humans. A case of A. variabilis infection in an immunocompetent men after friction burns in a car accident is described.

Invasive Infections with Multidrug-Resistant Yeast Candida auris, Colombia.

Candida auris is an emerging multidrug-resistant fungus that causes a wide range of symptoms. We report finding 17 cases of C. auris infection that were originally misclassified but correctly identified 27.

Paradoxical results of two automated real-time PCR assays in the diagnosis of pleural tuberculosis.

Tuberculosis (TB) is a major cause of worldwide mortality. We report the case of a non-HIV-infected woman with clinical suspicion of pleural tuberculosis and contradictory results between Xpert MTB/RIF and Abbott RealTime MTB assays from pleural fluid specimen. Liquid and solid cultures for tuberculosis were performed with negative results.

Multiplex PCR designed to differentiate species within the Candida glabrata complex.

Background: No phenotypic methods are available to unequivocally differentiate species within the Candida glabrata complex.

Aims: To develop a new multiplex PCR method to differentiate between the three species of the C. glabrata species complex, as well as using it to study a C.

Candida glabrata species complex prevalence and antifungal susceptibility testing in a culture collection: First description of Candida nivariensis in Argentina.

The presence of the cryptic species belonging to the Candida glabrata complex has not been studied in Argentina. We analyzed a collection of 117 clinical isolates of C. glabrata complex belonging to a National Culture Collection of Instituto Nacional de Microbiología "Dr.

Saksenaea erythrospora infection after medical tourism for esthetic breast augmentation surgery.

Background: Mucormycosis caused by Saksenaea erythrospora is rarely reported in humans. Three previous cases have been reported in the literature, two associated with trauma (a sailing accident in Argentina and a combat trauma in Iraq) and one as a cause of invasive rhinosinusitis (India), all in immunocompetent patients . The first case of mucormycosis following esthetic surgery, associated with medical tourism, is reported herein.
