Neonates, like older children and adults, are subject to viral infections acquired by horizontal routes, such as those due to influenza, rotavirus, and enteroviruses. They also are at risk for acquisition of viruses through routes that are unique to the perinatal setting where mother-to-child transmission (MTCT) occurs transplacentally, during birth, or from breast milk. The ability of certain ...
The human-pathogenic viruses in urban sewage have been extensively monitored to obtain information on circulating viruses in human communities. Enteroviruses (EVs) excreted by patients who present with diverse clinical syndromes can remain infectious in the environment for several weeks, and limited data on circulating environmental EVs are available. A 4-year (2009 to 2012) surveillance study ...
Confined aquifers are overlain by low-permeability aquitards that are commonly assumed to protect underlying aquifers from microbial contaminants. However, empirical data on microbial contamination beneath aquitards is limited. This study determined the occurrence of human pathogenic viruses in well water from a deep sandstone aquifer confined by a regionally extensive shale aquitard. Three pub...
Four poliomyelitis outbreaks caused by vaccine-derived polioviruses have been reported recently, including one in Madagascar in 2002. In all cases, the viral strains involved were recombinant between poliovirus vaccine strains and nonpoliovirus strains, probably enterovirus species C. Nevertheless, little is known about the circulation and epidemiology of enteroviruses in the regions where thes...
Picornaviruses are a diverse family of small, RNA viruses which include several pathogens of man and animals. They are divided, on the basis of physicochemical properties such as acid stability and buoyant density, into four main genera: enteroviruses, rhinoviruses, cardioviruses and aphthoviruses. The enteroviruses are the most important in terms of human pathogenicity and include the poliovir...
Persistence of enteroviruses in heart tissue has been implicated in the etiology of idiopathic dilated cardiomyopathy (IDC). Therefore, we determined the prevalence of enterovirus RNA in heart tissue from patients with end-stage IDC. During heart transplantation, 287 transmural biopsy specimens were aseptically collected from the explanted hearts of 38 patients with IDC and of 39 patients with ...
The 65 serotypes of human enteroviruses are classified into four species, Human enterovirus (HEV) A to D, based largely on phylogenetic relationships in multiple genome regions. The 3'-non-translated region of enteroviruses is highly conserved within a species but highly divergent between species. From this information, species-specific RT-PCR primers were developed that can be used to rapidly ...
