re Holmes Ball The advent of unbiased metagenomic virus discovery has revolutionized studies of virus biodiversity and evolution. Despite this, our knowledge of the virosphere, including in mammalian species, remains limited. We used unbiased metagenomic sequencing to identify RNA viruses in European field voles and rabbits. Accordingly, we identified a number of novel RNA viruses including astrovirus, rotavirus A, picorna-like virus and a morbilli-like paramyxovirus. In addition, we identified a sobemovirus and a novel luteovirus that likely originated from the rabbit diet. These newly discovered viruses were of...

This study applied a causal inference approach to data from a multisite study that deployed broadly inclusive diagnostics for numerous high-burden common enteropathogens. Relative risks (RRs) of infection with each pathogen during a flooding disaster that occurred at one of the sites—Loreto, Peru—were calculated from generalized linear models using a comparative interrupted time series framework with the other sites as a comparison group and adjusting for background seasonality. During the early period of the flood, increased risk of heat-stable enterotoxigenic E. coli (ST-ETEC) was identified (RR = 1.7...

This study investigated the prevalence of bovine coronavirus (BCoV), bovine norovirus (BNoV), bovine group A rotavirus (BoRVA), and bovine torovirus (BToV) in calves aged ≤ 60 days, regardless of diarrhea, across nine different regions in the Republic of Korea (ROK) and reported associations between these viruses and diarrhea. Fecal samples were collected rectally from 689 calves: normal (n = 360) and diarrheic (n = 329). BNoV (84/689, 12.2%) was the most prevalent regardless of diarrhea, followed by BCoV (37/689, 5.4%), BToV (15/689, 2.2%), and BoRVA (13/689, 1.9%). Although BCoV...

Abstract A rapid increase and dominance of G9P[8] Rotavirus A strains occurred in northern Vietnam between 2016 and 2018, during which period there appeared three G9P[8] strains possessing short RNA patterns. To understand how the first-ever G9P[8] strains possessing short RNA patterns were formed, next generation sequencing technology was used to examine the whole genomes of the three strains, i.e., RVA/Human-wt/VNM/RVN16.1024/2016/G9P[8], RVA/Human-wt/VNM/RVN17.0879/2017/G9P[8], and RVA/Human-wt/VNM/RVN18.0197/2018/G9P[8], and those of seven representative G9P[8] strains possessing long RNA patterns. The VP7 gen...

In conclusion, this work gives us a whole panorama of the pre-vaccine era of the RVA molecular epidemiology in the most populated region of Argentina. In this way, this work inspires us to continue with this type of studies in the post-vaccination era. PMID: 31931256 [PubMed - as supplied by publisher]

SUMMARY: Since 2005, it has been known that mother-to-child transmission of the chikungunya virus is possible. Transmission generally occurs in the perinatal period. In the present study, we describe the brain lesions seen on MR imaging of 6 cases of perinatal chikungunya infection. Patients who underwent brain MR imaging in the acute phase presented with areas of restricted diffusion in the white matter, suggesting a perivascular distribution, whereas those in the subacute/late phase showed cystic lesions, also with a perivascular distribution, with or without brain atrophy. One patient also presented with scattered hemor...

Purpose of review Rotavirus is a leading cause of viral acute gastroenteritis in infants. Neonates hospitalized in neonatal intensive care units (NICUs) are at risk of rotavirus infections with severe outcomes. The administration of rotavirus vaccines is only recommended, in the United States and Canada, upon discharge from the NICU despite rotavirus vaccines being proven well tolerated and effective in these populations, because of risks of live-attenuated vaccine administration in immunocompromised patients and theoretical risks of rotavirus vaccine strains shedding and transmission. We aimed to summarize recent evide...

Vlasova Rotavirus infection is the major cause of acute gastroenteritis among children globally. Sub-Saharan Africa including Ethiopia is disproportionally affected by the disease. The aims of this review were to determine the pooled prevalence of rotavirus infection among children under-five and to identify the dominant rotavirus genotypes in Ethiopia. Twelve studies were included to estimate the pooled prevalence of rotavirus acute gastroenteritis and five studies were used to determine predominantly circulating genotypes of rotavirus. The pooled prevalence of rotavirus infection was 23% (95% CI = 22%–24%)....
