Frecuencia de genes que codifican proteínas autotransportadoras serinproteasa de Enterobacteriaceae (SPATE) en cepas de Escherichia coli difusamente adherente (Daec) provenientes de niños con y sin di…
The aim of the study was to determine the frequency of six genes encoding serine protease autotransporter proteins Enterobacteriaceae (SPATE) in diffusely adherent Escherichia coli (DAEC) isolates from children with (WD, n=63) and without diarrhea (WOD, n=41) from Lima, Peru. WOD were considered a control group. For the detection of the genes, 2 multiple PCRs were standardized: triple A (sigA, pet, espP) and triple B (sat, pic, espC). In both gro…
Resistencia antimicrobiana de cepas comensales de Escherichia coli en niños de dos comunidades rurales peruanas
Antibiotic resistance is a major global problem. The objective of this study was to determine antibiotic resistance in commensal strains isolated from healthy children from rural communities of Moyobamba and Urubamba in Peru. This cohort study identified 179 commensal E. coli strains from 93 children, followed for six months. Thirteen antibiotics were analyzed by diffusion disk. The highest rates of resistance were for cotrimoxazole (49.1%), ampi…
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
Multirresistencia y factores asociados a la presencia de betalactamasas de espectro extendido en cepas de Escherichia coli provenientes de urocultivos
El tratamiento empírico para la infección urinaria se ve complicado frente a la presencia de multirresistencia y de betalactamasas de espectro extendido (BLEE). El objetivo del estudio fue describir los patrones de resistencia antibiótica de cepas de Escherichia coli aisladas en urocultivos y los factores clínico-epidemiológicos asociados a la presencia de BLEE en un grupo pediátrico y adulto. Se recolectaron durante 14 meses, 353 cepas provenien…
Enteropatógenos de importancia en salud pública
Diarrhea remains the third leading cause of death in children under five years, despite recent advances in the management and prevention of this disease. It is caused by multiple pathogens, however, the prevalence of each varies by age group, geographical area and the scenario where cases (community vs hospital) are recorded. The most relevant pathogens in public health are those associated with the highest burden of disease, severity, complicati…
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
