| Acute diarrheal disease is still one of the major public health problems worldwide. Rotaviruses (RV) are the most important viral etiologic agents and children under five years of age are the target population. OBJECTIVE: To investigate the rate of RV infection in hospitalized patients due to acute diarrhea in the cities of Ponta Grossa, Londrina and Assai - Paraná. METHODS: Latex agglutination (LA); immunochromatography (ICG); polyacrylamide gel electrophoresis (PAGE) and negative staining electron microscopy (ME) tests were used to detect the virus. For the genotyping, RT-PCR and RT-PCR-ELISA were used, respectively, for NSP4 and VP4/VP7. RESULT: Out of 124 samples there were 69 positive stool samples for RV, for at least one of the used tests, 67 of... |

| OBJECTIVE: Determine the prevalence of Vancomycin-resistant enterococci (VRE) colonizing the intestinal tract of hospitalized patients and define risk factors. MATERIAL AND METHODS: A point prevalence survey of VRE fecal carriage was carried out among patients who stayed at a 600-bed teaching hospital for at least two days. Resistance to vancomycin was detected by the E-test method. Epidemiological data was recorded for all patients included in the study and was used for the risk factor analysis. RESULTS: A total of 128 patients hospitalized for at least two days were enrolled in this investigation. Thirty-nine patients (30.5%) were colonized with vancomycin-resistant enterococci. Twenty-three of the 39 strains were identified as Enterococcus faecium, 13... |
