A Novel Terrestrial Rabies Virus Lineage Occurring in South America: Origin, Diversification, and Evidence of Contact between Wild and Domestic Cycles.

The rabies virus (RABV) is characterized by a history dominated by host shifts within and among bats and carnivores. One of the main outcomes of long-term RABV maintenance in dogs was the establishment of variants in a wide variety of mesocarnivores. In this study, we present the most comprehensive phylogenetic and phylogeographic analysis, contributing to a better understanding of the origins, diversification, and the role of different host species in the evolution and diffusion of a dog-related variant endemic of South America.

Evaluation of Two Real-Time, TaqMan Reverse Transcription-PCR Assays for Detection of Rabies Virus in Circulating Variants from Argentina: Influence of Sequence Variation.

In rabies diagnosis, it is essential to count on a rapid test to give a quick response. The combined sensitivity and robustness of the TaqMan RT-PCR assays (qRT-PCR) have made these methods a valuable alternative for rabies virus (RABV) detection. We conducted a study to compare the applicability of two widely used qRT-PCR assays targeting the nucleoprotein gene (LysGT1 assay) and leader sequences (LN34 qRT-PCR assay) of RABV genomes, in all variants circulating in Argentina.

Global phylodynamics of Echovirus 30 revealed differential behavior among viral lineages.

Echovirus 30 (E30) is an important causative agent of aseptic meningitis worldwide. Despite this, the global and regional dispersion patterns, especially in South America, are still largely unknown. We performed an in-depth analysis of global E30 population dynamics, by using the VP1 sequences of 79 strains isolated in Argentina, between 1998 and 2012, and 856 sequences from GenBank.

Atypical hand, foot, and mouth disease caused by Coxsackievirus A6 in Argentina in 2015.

We present two groups of cases of atypical hand, foot, and mouth disease (HFMD) caused by Coxsackievirus A6 (CV-A6) detected in Argentina in 2015. The first group involved 14 patients from Chubut province and the second group affected 12 patients from San Luis province. Molecular analysis of the complete VP1 protein gene revealed the circulation of E2 sublineage, the most predominant worldwide.

Unusual increase of cases of myelitis in a pediatric hospital in Argentina.

Introduction: The association between enterovirus D68 and acute flaccid myelitis was first described in the United States in 2014. Since then, sporadic cases have been reported in Canada and Europe. This study describes a series of cases of acute flaccid myelitis at Hospital de Pediatría "Prof.

Diversity of picornaviruses in rural Bolivia.

The family Picornaviridae is a large and diverse group of viruses that infect humans and animals. Picornaviruses are among the most common infections of humans and cause a wide spectrum of acute human disease. This study began as an investigation of acute flaccid paralysis (AFP) in a small area of eastern Bolivia, where surveillance had identified a persistently high AFP rate in children.

[Epidemiology of enterovirus associated with neurologic diseases].

This report describes the results of human enterovirus (HEV) detection and characterization using cell culture, polymerase chain reaction and molecular typing in 2167 samples obtained from acute flaccid paralysis, aseptic meningitis and acute encephalitis patients, from 1991 to 1998 in Argentina. HEV were isolated in 130 out of 666 cases (19.5%) and 36 out of 666 (5.

[Neurologic disease due to adenovirus infection].

The aim of this study was to assess the prevalence of adenovirusm (ADV) infections in neurological disorders. A total of 108 cerebrospinal fluid (CSF) samples from 79 encephalitis cases, 7 meningitis and 22 other neurological diseases analysed in our laboratory between 2000 and 2002 were studied. Forty nine (47.
