Echovirus 7 enters polarized Caco-2 intestinal epithelial cells by a clathrin-mediated endocytic process and then moves through the endosomal system before releasing its genome into the cytoplasm. We examined the possible role in virus entry of core components of the autophagy machinery. We found that depletion of Beclin-1, Atg12, Atg14, Atg16, or LC3 with specific small interfering RNAs inhibi...

BACKGROUND Human enteroviruses have long been associated with various diseases of man resulting into a wide range of acute symptoms involving the cardiac and skeletal muscles, central nervous system, pancreas, skin and mucous membranes. OBJECTIVE To assess the role of enteroviruses in the etiology of hypertension, DCM and HHF. METHODS We obtained stool specimens from 70 subjects comprising ...

Ultraviolet light in the UVC range is a commonly used disinfectant to control viruses in clinical settings and water treatment. However, it is currently unknown whether human viral pathogens may develop resistance to such stressor. Here, we investigate the adaptation of an enteric pathogen, human echovirus 11, to disinfection by UVC, and characterized the underlying phenotypic and genotypic cha...

Fresh water obtained from nine sources was shown to cause inactivation of poliovirus. Further testing with four of these water samples showed that enteric viruses from different genera were consistently inactivated in these freshwater samples. Studies on the cause of inactivation were conducted with echovirus type 12 as the model virus. The results revealed that the virucidal agents in the wate...

Solar disinfection (SODIS) of drinking water in polyethylene terephthalate (PET) bottles is a simple, efficient point-of-use technique for the inactivation of many bacterial pathogens. In contrast, the efficiency of SODIS against viruses is not well known. In this work, we studied the inactivation of bacteriophages (MS2 and ϕX174) and human viruses (echovirus 11 and adenovirus type 2) by SODIS....
