The prevalence of human astroviruses was tested in patients with acute gastroenteritis by using conventional duplex reverse transcription (RT)-PCR and electrophoresis. Diarrheal fecal samples were collected from 9,597 patients at local hospitals in Seoul. The prevalence of astroviruses was 1.0% (94/9,597 patients; mostly infants), and that of sapoviruses was 0.1% (14/9,597 patients). Age- and g...

Several novel astroviruses have been recently discovered in humans and in other animals. Here, we report results from our surveillance of astroviruses in human and rodent faecal samples in Hong Kong. Classical human astroviruses (n=9) and a human MLB1 astrovirus were detected in human faecal samples (n=622). Novel astroviruses were detected from 1.6 % of the faecal samples of urban brown rat (R...

Using viral metagenomics of brain tissue from a young adult crossbreed steer with acute onset of neurologic disease, we sequenced the complete genome of a novel astrovirus (BoAstV-NeuroS1) that was phylogenetically related to an ovine astrovirus. In a retrospective analysis of 32 cases of bovine encephalitides of unknown etiology, 3 other infected animals were detected by using PCR and in situ ...

Astroviruses were first identified over 30 years ago and the virus was soon established as an important cause of gastroenteritis, particularly in young children. Human astrovirus disease was thought to result from infection by a limited number of serotypes. However, recent studies have indicated that the extent of genetic diversity is greater than previously assumed. In addition, the widespread...

Introduction The technology developed by Antenna Technologies has allowed reaching some promising results. In Guinea Conakry, The sales of Sodium Hypochlorite (SH) flasks in a limited zone (target population for 2014: 7’218’882) represent a calculated coverage ratio of 27,5% (2014: 3’390’637 flasks sold at very low price to lowest income group). In Burkina Faso, the excellent results obtained b...

This paper presents the findings of an investigation into the treatment of oral diseases with medicinal plants in the Kadiogo province, Burkina Faso. Although the region is mainly urban, it appears that traditional healers who live there, and the general population, continue to rely on plant products when dealing with a broad range of oral health concerns. Sixty-two relevant species belonging t...

filariasis in dogs is caused by several species of filariids. because of importance of this infection in veterinary medicine and public health, it is necessary to carry out an epidemiological and cross sectional studies in various geographical areas and use of well-adapted diagnosis methods. in this study 205 capillary and whole blood samples were collected from doges in various counties of eas...

Between 2016 and 2018, the prevalence of porcine kobuvirus (PKoV) astrovirus (PAstV) in Korean wild boars (n = 845) was 28.0% 10.7%, respectively. Coinfection by both viruses detected 5.1% boars. Phylogenetic analysis revealed that 134 PKoV isolates belonged to diverse lineages within species Aichivirus C; however, one strain (WKoV16CN-8627) clustered with bovine (Aichivirus B). Forty-seven PAs...

Human astroviruses (HAstVs) are a common etiological agent of infantile gastroenteritis. Recent studies revealed that novel astrovirus (AstV) strains of the MLB clade (MLB-AstVs) and VA clade (VA-AstVs), which are genetically distinct from the classic HAstVs, are circulating in the human population. In the present study, we quantified classic HAstVs as well as carried out a genetic analysis of ...
