One hundred and twenty-six epidemiologically sequential, unrelated, carbapenem-resistant Acinetobacter baumannii isolates from nine hospitals in six countries of South America were collected between July 2013 June 2014. Genes coding for Ambler class D B carbapenemases sought by PCR. All typed using the 3-locus sequence typing blaOXA-51-like sequence-based techniques. The blaOXA-23 gene was recovered all participating seven medical centres. blaOXA-72 only two centres Guayaquil city, Ecuador....
We characterized 34 methicillin-resistant Staphylococcus aureus strains isolated in Paraguay 2005. The belonged to two clones. major clone (sequence type 5 [ST5] or ST221, spa t149, staphylococcal cassette chromosome mec [SCCmec] I) was similar the Cordobes/Chilean spreading through South America, and minor (ST239 ST889, t037, SCCmec IIIA) related Brazilian clone.
Introduction: Staphylococcus aureus is considered one of the most important human pathogens, and its levels resistance to methicillin have increased even in strains isolated from people without nosocomial risk factors. Molecular analysis essential for understanding patterns dissemination. The objective this study was identify community-acquired methicillin-resistant S. (CA-MRSA) clones that infected Paraguayan children patients two periods time.
 Methodology: An observational,...
Community-acquired Staphylococcus aureus isolated from Paraguayan children: clinical, phenotypic and genotypic characterization Introduction: The prevalence of in the community has increased, being pediatric population most affected.This fact highlights need for epidemiological surveillance.Aim: To characterize isolates S. children's samples with community-acquired infections, collected hospitals Asuncion Central Department, between November 2009 December 2010.Materials Methods: Descriptive...
La resistencia a las polimixinas mediada por plásmidos (gen mcr-1) representa una amenaza para la salud pública, puesto que colistina es utilizada en práctica médica como de últimas alternativas el tratamiento gérmenes multiresistentes. Este estudio describe circulaciónde cepas Enterobacterias portan este gen resistencia, aisladas pacientes hospitalizados, asà también comunidad. Los hallazgos Red Vigilancia Resistencia los Antimicrobianos-Paraguay fueron casi 5 % (4,7) remitidas con...
Introducción: La capacidad de S. aureus para adherirse a superficies y otras células bacterianas, conformar un biofilm, es una las principales causas la persistencia infecciones por este patógeno.
Streptococcus pneumoniae sigue siendo una de las causas más importantes morbilidad y mortalidad en niños adultos alrededor del mundo. El objetivo estudio fue describir la frecuencia aislamiento S. enfermedad invasiva, distribución serotipos sensibilidad antimicrobiana Paraguay (2010-2018). Se estudiaron 793 cepas aisladas pacientes todas edades con invasiva Paraguay, provenientes los diferentes centros centinelas colaboradores el marco vigilancia meningitis neumonÃas, durante periodo...
The antimicrobial resistance of <i>Pseudomonas aeruginosa</i> to beta-lactams, aminoglycosides and ciprofloxacin was investigated in two Latin American hospitals, one Venezuela the other Paraguay. <i>P. 1,481 clinically isolated strains, 988 from Asunción 493 Caracas, collected between 1996 1999. Susceptibility assessed by disk diffusion method according National Committee for Clinical Laboratory Standards. 11.4% were resistant cefoperazone, ceftazidime, 12.8% piperacillin,...
Las betalactamasas de espectro extendido (BLEE), son enzimas responsables la hidrólisis del anillo betalactámico penicilinas y cefalosporinas, excepto carbapemenes, inhibiendo así su actividad terapéutica.Si bien es posible detección fenotípica este mecanismo resistencia por métodos convencionales, sólo los moleculares permiten identificación gen responsable dicha resistencia.El objetivo estudio descriptivo retrospectivo fue identificar genes bla CTX-M2 , PER-2 SHV TEM en aislamientos...
Introduction.Streptococcus pneumoniae remains a major cause of mortality and morbidity worldwide in children <5 years age, even with advances vaccination programmes.Hypothesis/Gap Statement. Reviewing reporting trends the distribution pneumococcal serotypes antimicrobial resistance Paraguay will be useful for decision-making public health.Aim. This study analysed serotype S. characteristics disease old before after introduction conjugate vaccines (PCVs).Methodology. A total 885 isolates 278...
Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) is one of the first causes skin and soft tissue infections, can also produce severe diseases such as osteomyelitis pneumonia. The aim this descriptive study was to determine SCCmec type virulence profile genetic diversity by MLVA analysis 21 CA-MRSA isolates that infected Paraguayan children in 2010. factors were performed PCR (multiple locus variable analysis). All carried cassette iv. hla, hlb sea genes detected...
