Although in the last years poliovirus (PV) transmission has been reported at the lowest levels ever recorded, the spread of virus from endemic countries endures; the high levels of immigration flows across the Mediterranean Sea jeopardize Italy for PV reintroduction. The World Health Organization (WHO) strategic plan for global poliomyelitis (polio) eradication indicates the nationwide surveillance of Acute Flaccid Paralysis (AFP) as the gold standard for detecting cases of polio. In addition, the Environmental Surveillance (ES), seeking the presence of PV and Non-Polio Enterovirus (NPEV) in sewage, is recognized as a powerful tool to confirm PV circulation in absence of AFP cases, especially in polio-free countries...

We experienced 13 cases (29.8 ± 7.0 years) of mumps meningitis and 365 cases of adult aseptic meningitis during 11 years from 2004 to 2014. A small epidemic of mumps occurred for 3-4 years, and the incidence rate of adult mumps meningitis coincided with the epidemic without seasonal fluctuation. Parotitis was observed in 8 of the 13 mumps meningitis patients (61.5%) and orchitis in 2 of 7 male patients (28.6%). There were no differences in clinical manifestations, laboratory findings, and outcome between patients with adult mumps meningitis and those with echovirus 9 meningitis (9 patients), except for the low frequency of nausea/vomiting and a high percentage of mononuclear cells of the cerebrospinal fluid in those with mumps...

Human echovirus 11 (E-11), a member of the species Enterovirus B, frequently causes aseptic meningitis and hand, foot and mouth disease (HFMD). We determined the complete genome sequence of strain 520K/YN/CHN/2010, isolated from a subject with HFMD and aseptic meningitis in Yunnan Province, China, in 2010. The strain shared 78.8% and 81.1% nucleotide sequence similarity with prototype strain Gregory in the complete VP1 gene and the complete genome, respectively. Only the VP2-VP3-VP1 genome region of 520K/YN/CHN/2010 was similar to that of the E-11 strain; the other genome regions were most similar to those of other members of the species Enterovirus B...

Over 100 known enterovirus serotypes differ in their epidemiological and pathogenic properties. Much less is known about variation of these features on a sub-serotype level, such as genotypes. Echovirus 11 (E11) and E30 are amongst the most frequent causative agents of aseptic meningitis. We studied the molecular epidemiology of these pathogens to evaluate potential epidemiological and pathogenic dissimilarities of their genotypes. The complete VP1 genome region was sequenced for 97 E11 and 62 E30 isolates collected in Russia from 2008 to 2012, and they were studied in comparison with all 140 E11 and 432 E30 sequences available in GenBank...

Pleconaril is a capsid inhibitor used previously to treat enterovirus infections. A pleconaril-resistant echovirus 11 (E11) strain was identified before pleconaril treatment was given in an immunocompromised patient. The patient was also treated with intravenous Ig (IVIg) for a long period but remained unresponsive. The pleconaril-resistant strains could not be neutralized in vitro, confirming IVIg treatment failure. To identify the basis of pleconaril resistance, genetic and structural analyses were conducted...
