Distribution of the bla OXA, bla VEB-1, and bla GES-1 genes and resistance patterns of ESBL-producing Pseudomonas aeruginosa isolated from hospitals in Tehran and Qazvin, Iran

Abstract INTRODUCTION: Pseudomonas aeruginosa is one of the most common nosocomial pathogens. The emergence of extended spectrum β-lactamases (ESBLs) has been increasingly reported as a major clinical concern worldwide. The main aim of the present study was to determine the distribution of bla OXA,...

Characterization of biofilm formation, antimicrobial resistance, and staphylococcal cassette chromosome mec analysis of methicillin resistant Staphylococcus hominis from blood cultures of children

Abstract INTRODUCTION: Methicillin resistant Staphylococcus hominis (MRSHo) has been recognized as an important human pathogen, particularly in immunocompromised patients. METHODS: A total of 19 S. hominis isolates were collected from children at the Children's Medical Centre, Tehran, Iran, from Marc...

Molecular detection of β-lactamase and integron genes in clinical strains of Klebsiella pneumoniae by multiplex polymerase chain reaction

Abstract INTRODUCTION: Infections caused by β-lactamase-producing gram-negative bacteria, such as Klebsiella pneumoniae, are increasing globally with high morbidity and mortality. The aim of the current study was to determine antimicrobial susceptibility patterns and the prevalence of antibiotic r...

Tratamiento antibiótico empírico de elección en pacientes con urosepsis secundaria a litiasis ureteral: reporte de sensibilidad local

Rev. méd. Chile; 145 (6), 2017
Background: Early inappropriate antibiotic therapy for the management of urosepsis is associated with higher mortality. Therefore, to establish an adequate empirical therapy is crucial. Aim: To determine an optimal antibiotic treatment, adjusted according local bacterial resistance in patients diagnosed...

Resistance among Gram-negative ESKAPE pathogens isolated from hospitalized patients with intra-abdominal and urinary tract infections in Latin American countries: SMART 2013-2015

Braz. j. infect. dis; 21 (3), 2017
ABSTRACT Gram-negative ESKAPE pathogens (Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species) are important etiologic agents of nosocomial infection that are frequently resistant to broad-spectrum antimicrobial agents. Gram-negative ESKAPE pathogens were colle...

Sensibilidad a los antimicrobianos de aislamientos de Helicobacter pylori aislados de lesiones gástricas

Rev. argent. microbiol; 49 (2), 2017
Se evaluó la sensibilidad a los antimicrobianos de 30 aislamientos de Helicobacter pylori aislados de biopsias gástricas mediante los métodos de difusión por discos y tiras de E-test. Los antimicrobianos evaluados fueron amoxicilina, claritromicina, metronidazol y ciprofloxacina. No se encontraron ce...

Triazine Compound as Copolymerized Antibacterial Agent in Adhesive Resins

Braz. dent. j; 28 (2), 2017
Abstract The aim of this study was to formulate and evaluate an experimental adhesive resin with the addition of 1,3,5-triacryloylhexahydro-1,3,5-triazine at different concentrations. Experimental adhesive resins were obtained by mixing 50% wt bisphenol A glycol dimethacrylate (BisGMA), 25% wt triethylen...

Surveillance of bacteria Pseudomonas aeruginosa and MRSA associated with chronic suppurative otitis media

Abstract Introduction: Suppurative otitis media is a critical disease causing perforation of the tympanic membrane associated with changes of the mucoperiosteum of the middle ear cleft. Objective: To isolate causative bacteria from chronic suppurative ear discharges and to ascertain their antibiotic pr...

Etiología aerobia de apendicitis aguda en adultos: Estudio multicéntrico de la sepsis abdominal en Argentina
Aerobic etiology of acute appendicitis in adults. Multicenter study of abdominal sepsis in Argentina

Medicina (B.Aires); 77 (2), 2017
El tratamiento antibiótico de las apendicitis agudas se decide empíricamente basándose en la información epidemiológica. Las resistencias son variables entre regiones y los datos de Argentina son escasos. En el contexto de un estudio multicéntrico, observacional, de infecciones abdominales, se efec...

Evaluación de la susceptibilidad directa desde hemocultivos positivos utilizando el sistema Vitek 2: comparación de dos protocolos rápidos

Rev. chil. infectol; 34 (2), 2017
Antimicrobial susceptibility testing using Vitek® 2 (bioMérieux) cards inoculated directly from positive blood cultures was compared with the standard method for gramnegative rods. Two different protocols for the inoculum preparation were evaluated. Protocol 2 was faster and easier to perform. Rapid su...
