The aim of this study was to investigate the genetic variability of echovirus 6 (E6) isolates from environmental samples and clinical cases of aseptic meningitis from 2006 to 2014. The analysis of the VP1 region showed the extensive diversity (up to 18.8%) and revealed that E6 circulating in Poland belong to four groups. Environmental strains clustered in three groups excepting the 2012 outbreak group, which shows the sudden introduction of new epidemic variant with Asiatic origin. Data from the study established relationships of E6 from Poland with previously characterized strains and confirmed the importance of both clinical and environmental surveillance...

We have demonstrated previously that the human picornavirus Echovirus 1 (EV1) triggers an infectious internalization pathway that follows closely, but seems to stay separate from the EGFR pathway triggered by EGF. Here we confirmed by using live and confocal microscopy that EGFR and EV1 vesicles are following intimately each other but are distinct entities with different degradation kinetics. We show here that despite being sorted to different pathways and located in distinct endosomes, EV1 inhibits EGFR down-regulation...

Enteroviruses (EVs) are the most common viral agents in humans. Although most infections are mild or asymptomatic, there is a wide spectrum of clinical manifestations that may be caused by EV infections with varying degrees of severity. Among these viruses, EV-A71 and coxsackievirus (CV) CV-A16 from group A EVs attract the most attention because they are responsible for hand, foot and mouth disease (HFMD). Other EV-A viruses such as CV-A6 and CV-A10 were also reported to cause HFMD outbreaks in several countries or regions...

In October and November 2010, six children and one woman were presented with symptoms of aseptic meningitis in Jena, Thuringia, Germany. Enterovirus RNA was detected in the cerebrospinal fluid of all patients by RT-PCR, and preliminary molecular typing revealed echovirus 18 (E-18) as causative agent. Virus isolates were obtained from stool samples of three patients and several contact persons. Again, most isolates were typed as E-18. In addition, coxsackievirus B5 (CV-B5) and echovirus 25 (E-25) were found to co-circulate...

Coxsackievirus (Cox) B is the second common picornaviruses, after echovirus, detected from children younger than 2 months of age. Neonates who present with Cox B3 infection in the first week are known to have severe illness such as myocarditis or menigoencephalitis. Severity is commonly associated with perinatal vertical transmission. Here, we report a neonatal case of Cox B3 infection with severe thrombocytopenia through horizontal transmission. The patient was a preterm infant born without asphyxia by selective cesarean section...

UNLABELLED: One of the hallmarks of enterovirus genome delivery is the formation of an uncoating intermediate particle. Based on previous studies of mostly heated picornavirus particles, intermediate particles were shown to have externalized the innermost capsid protein (VP4) and exposed the N terminus of VP1 and to have reduced infectivity. Here, in addition to the native and intact particle type, we have identified another type of infectious echovirus 1 (E1) particle population during infection...

Primary immunodeficiencies (PIDs) encompass more than 250 different pathological conditions. X-linked agammaglobulinemia (XLA) has been occasionally associated with cutaneous and muscular manifestations resembling dermatomyositis, often termed dermatomyositis-like syndrome (DLS). This syndrome has been associated with cutaneous, muscular and central nervous system manifestations, accompanying a persistent infection by an Echovirus. According to sixteen previously reported cases, this syndrome has a poor prognosis...

Recently, a cell-culture independent protocol for detection of enteroviruses from clinical specimen was recommended by the WHO for surveillance alongside the previously established protocols. Here, we investigated whether this new protocol will show the same enterovirus diversity landscape as the established cell-culture dependent protocols. Faecal samples were collected from sixty apparently healthy children in Ibadan, Nigeria. Samples were resuspended in phosphate buffered saline, RNA was extracted, and the VP1 gene was amplified using WHO recommended RT-snPCR protocol...
