| Para determinar los contenidos de cadmio, cobre, zinc y plomo en hojas, tallos y raíces de Rhizophora mangle se tomaron muestras en tres parcelas ubicadas en la desembocadura del río Sevilla-Ciénaga Grande de Santa Marta, en octubre de 2003. Las mediciones de las concentraciones de metales, se hicieron mediante la técnica de espectrometría de emisión atómica de plasma inductivamente acoplado (ICP-AES). Los resultados indicaron que la concentración de plomo en órganos de R. mangle estuvo bajo el límite de detección del método utilizado (<2.38 μg/g), a excepción de las raíces absorbentes (16.3 μg/g); y que existen diferencias significativas en los contenidos de cadmio, cobre y zinc entre órganos de R. mangle, encontrándose el siguiente orden de... |

| Several cases of Candida bloodstream infections were documented from June to October 2004 at a tertiary care center in Bogotá, Colombia. Since no cases of candidemia had occurred during the preceding four months, an outbreak was declared. As a result, a microbiological study, a revision of infection control practices and a case-control study were performed. In all, 18 cases of candidemia were ascertained. Parenteral nutrition (p=0.04), presence of a central line (p=0.03), and severity of illness (p=0.03) were associated with candidemia in bivariate analysis. Diverse Candida species were observed. Candida parapsilosis contamination was found in plastic containers used for transient intravenous (IV) medication storage at the bedside, plastic bags reused for... |

| OBJECTIVES: This study was designed to simulate standard and optimized dosing regimens for intravenous antibiotics against contemporary populations of Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa using MIC distribution data to determine which of the tested carbapenem regimens provided the greatest opportunity for obtaining maximal pharmacodynamic (PD) activity. METHODS: The isolates studied were obtained from the COMPACT-COLOMBIA surveillance program conducted between February and November 2009. Antimicrobial susceptibility testing was conducted by broth microdilution method according to the CLSI guidelines. Doripenem, imipenem-cilastatin, and meropenem, were the modeled antibiotics. A 5,000 patient Monte... |

| Background:Bloodstream infection by Candida species has a high mortality in Latin American countries. The aim of this study was to describe the characteristics of patients with documented bloodstream infections caused by Candida species in third level hospitals and determine the risk factors for in-hospital-mortality.Methods:Patients from seven tertiary-care hospitals in Bogotá, Colombia, with isolation of a Candida species from a blood culture were followed prospectively from March 2008 to March 2009. Epidemiologic information, risk factors, and mortality were prospectively collected. Isolates were sent to a reference center, and fluconazole susceptibility was tested by agar-based E-test. The results of susceptibility were compared by using 2008 and 2012... |

| ABSTRACT Dengue, the most prevalent arboviral disease worldwide, is caused by any of the four dengue virus (DENV) serotypes that co-circulate constantly in hyperendemic areas such as Medellin (Colombia), and these serotypes are transmitted by mosquitoes of the genus Aedes. In this study, we evaluated the replicative capacity of strains isolated in Medellin between 2003 and 2007 in C6/36 cells and in colonies of Aedes aegypti collected during 2010-2011 from high or low-incidence areas within the same city. The phylogenetic analysis grouped isolates according to the predominant genotypes found in the Americas, and the in vitro characterization showed differences in the morphological changes induced by the isolates of each of the isolated serotypes compared... |

| OBJECTIVE: Describe the presence of CTX-M-1 phylogenetic subgroup extended-spectrum i-lactamases (ESBL), associated with TEM and SHV genes, and the gene encoding cephalosporinase, CMY-2 in Escherichia coli and Klebsiella pneumoniae isolates from community-acquired urinary tract infections. METHODS: 102 E. coli and 21 K. pneumoniae were collected from patients with culture-proven urinary tract infection (UTI), during February and March, 2011. Antimicrobial susceptibility test was performed by disk diffusion according to the standards of the Clinical Laboratory Standard Institute. Screening for cephalosporins-resistant E. coli and K. pneumoniae was performed by PCR assay for blaTEM, blaSHV, blaCTX-M-1,-2,-8,-9, blaPER-2 and blaCMY-2 genes. Statistical... |
