Detección de Streptococcus pneumoniae en líquidos estériles mediante una PCR en tiempo real (qPCR) en pacientes hospitalizados con sospecha de enfermedad neumocócica invasiva
The standard for diagnosing invasive pneumococcal disease (IPD) is to isolate pneumococcus in culture. However, the etiological agent cannot be identified in some patients, especially those who received empirical antibiotic therapy. This study aimed to detect pneumococcus in normally sterile fluids by qPCR in patients with suspected IPD hospitalized in Lima. qPCR had a detection limit of 1.2 x 101 genome copies/uL. Of the 71 clinical samples (51 …
Distribución de serotipos, biotipo y sensibilidad antibiótica de Haemophilus influenzae en niños portadores nasofaríngeos en Lima, Perú
After the introduction of the Hib (Haemophilus influenzae type b) vaccine, invasive infection caused by this bacterium markedly decreased; however, concern increased regarding the other typable and non-typable strains (NTHi). Prior colonization with this pathogen can become a source of invasive infection. This study aimed to determine colonization by H. influenzae in 888 healthy children under 24 months of age. Colonization was 4.1% (37 samples) …
Presencia de Enterobacteriaceae y Escherichia coli multirresistente a antimicrobianos en carne adquirida en mercados tradicionales en Lima
Multiple drug resistance levels were high compared to antibiotics frequently used in humans; chicken and beef are highlighted as potential reservoirs of BLEE and pAmpC-producing Escherichia coli, respectively
Frecuencia y patotipos de Escherichia coli diarrogénica en niños peruanos con y sin diarrea
Introduction. Diarrheagenic E. coli (DEC) are a major cause of diarrhea in children in developing countries. However, they are not part of routine diagnosis in clinical laboratories. Objectives. To determine the DEC prevalence in Peruvian children and to describe the genetic variability of these strains. Materials and methods. A total of 8 003 E. coli strains previously isolated from eight different studies of diarrhea in children, mainly from pe…
Patrones de adherencia de cepas de Escherichia coli Difusamente adherente (Daec) provenientes de niños con y sin diarrea
Our findings suggest a difference between adherence patterns, actin polymerization and motility between DAEC strains corresponding to diarrhea and control groups. The significance of these results must be confirmed with a bigger number of strains and determining the presence of virulence genes in the strains
Patrones de adherencia de cepas de Escherichia coli difusamente adherente (Daec) provenientes de niños con y sin diarrea
Introduction. Diffusely adherent E. coli (DAEC) is the sixth recognized group of diarrheagenic E. coli. However, its association with diarrhea remains controversial. Variability in the adherence patterns of clinical strains is unknown. Objectives. To compare the adherence patterns between strains isolated from children with and without diarrhea. Materials and methods. A total of 31 DAEC strains were analyzed, 25 from children with diarrhea and 6 …
Frecuencia y patotipos de Escherichia coli diarrogénicas en niños peruanos con y sin diarrea
DEC are a major cause of diarrhea in Peruvian children. These pathogens are highly heterogeneous. Additional studies are required to determine the prevalence in rural areas of Peru and in severe diarrhea cases
