| The aqueous extract of Agaricus blazei Murill ss. Heinem, a basidiomycete native from Brazil, frequently used by popular medicine, mainly in the form of tea, was assessed to its antiviral action against herpes simplex type 1 (HSV-1) and bovine herpes type 1 (BoHV-1) in HEp-2 cell culture. Viral replication inhibition was evaluated by plaque assay and immunofluorescence test. The extract demonstrated virucide action for both viruses, being more effective against HSV-1, inhibiting its infectivity in 78.4 and 73.9% at the concentrations of 50 and 100 µg/mL, respectively moreover, reduction in 47% the number of fluorescent cells was observed for both concentrations. The extract also showed discrete therapeutic activity. These results suggest that A. blazei... |

| 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... |

| Rotaviruses are common pathogens and the causal agents of acute diarrhea among children and young animals. The involvement of rotavirus in human diarrheal disease among population of urban and rural areas of the city of Londrina, Parana was evaluated. Nine hundred and five fecal specimens from persons with diarrhea were studied, being 686 and 219 from urban and rural areas, respectively. Thirty-eight samples (4,2%) were positive for rotavirus by polyacrylamide gel electrophoresis of viral RNA and latex agglutination test of which 36 were from urban and two from rural areas. Out of the positive specimens, 17 strains were further characterized by RT-PCR typing assay, resulting in 16 strains of G1 genotype while one sample was found to be a mixture of G1 and... |
