Human noroviruses are the most common cause of acute viral gastroenteritis, and the environmental persistence of these viruses contributes to their transmissibility. Environmental sampling is thus an important tool for investigating norovirus outbreaks and for assessing the effectiveness of cleaning and decontamination regimens. The purpose of this study was to evaluate a sampling material (wipes) for their efficacy at recovering human norovirus from hard surfaces and foods. Dilutions of a human norovirus GII...

Since they were identified in 1975, human astroviruses have been considered one of the most important agents of viral acute gastroenteritis in children. However, highly divergent astroviruses infecting humans have been recently discovered and associated with extra-intestinal infections. The report of cases of fatal meningitis and encephalitis, especially in immunocompromised individuals, has broadened their disease spectrum. Although zoonotic transmission among animal and human astroviruses has not been clearly recognized, the genetic similarity between some human and animal viruses makes it likely to occur...

Campylobacter is a major cause of foodborne illnesses worldwide. Campylobacter infections, commonly caused by ingestion of undercooked poultry and meat products, can lead to gastroenteritis and chronic reactive arthritis in humans. Whole genome sequencing (WGS) is a powerful technology that provides comprehensive genetic information about bacteria and is increasingly being applied to study foodborne pathogens: e.g., evolution, epidemiology/outbreak investigation, and detection. Herein we report the complete genome sequence of Campylobacter coli strain YH502 isolated from retail chicken in the United States...

Sewage samples have been investigated to study the level of noroviruses concentration in sewage or the genotypes of noroviruses circulating in human populations. However, the statistical relationship between the concentration of the virus and the number of infected individuals, and the clinical importance of genotypes or strains detected in sewage are unclear. In this study, we carried out both environmental and clinical surveillance of noroviruses for three years: 2013-2016. We performed cross-correlation analysis between the concentrations of norovirus GI or GII in sewage samples collected weekly and the number of gastroenteritis cases...

BACKGROUND: When the permeability of the glomerular filtration barrier increases, leading to proteinuria, nephrotic syndrome (NS) occurs. First episodes or relapses of NS can be concurrent with acute gastroenteritis (AGE) infections. This condition can cause further deterioration of the hypovolemic state, as intravascular water is lost through both AGE-related vomiting/diarrhea and NS-related fluid shifting into the interstitium. In this case report, we wish to raise the issues about the difficult management of children presenting with both NS and AGE...

Previous reports have demonstrated that the second-generation tetracycline derivative doxycycline (DOX) interrupts mitochondrial proteostasis and physiology, inhibits proliferation of many cell types, and induces apoptosis. However, the effects of DOX, which is widely used in porcine husbandry by feed, on the porcine intestinal epithelium are unclear. In this study, we demonstrated that DOX damaged mitochondrial morphology and induced the co-localization of mitochondria with autophagosomes, suggesting that DOX induces mitophagy in IPEC-J2 cells...

Comamonas testosteroni (formally Pseudomonas testosteroni) is common environmental bacterium that is not part of the human microbiome. Since its identification as a human pathogen in 1987, numerous reports have drizzled in, implicating this organism for various infections. Although these organisms are of low virulence, some of their obscurity perhaps is due to the incapability of clinical laboratories to identify them. Most of the reported cases are bloodstream infections. We report a case of gastroenteritis caused by this organism in a 65-year-old female with colostomy in situ...

The development of porcine epidemic diarrhea virus (PEDV) antibody-based assays is important for detecting infected animals, confirming previous virus exposure, and monitoring sow herd immunity. However, the potential cross-reactivity among porcine coronaviruses is a major concern for the development of pathogen-specific assays. In this study, we used serum samples (n = 792) from pigs of precisely known infection status and a multiplex fluorescent microbead-based immunoassay and/or enzyme-linked immunoassay platform to characterize the antibody response against PEDV whole-virus (WV) particles and recombinant polypeptides derived from the four PEDV structural proteins, i...

Human norovirus (HNoV), a positive-sense RNA virus, is the main causative agent of acute viral gastroenteritis. Multiple pandemic variants of the genogroup II genotype 4 (GII.4) of NoV have attracted great attention from researchers worldwide. However, novel variants of GII.17 have been overtaking those pandemic variants in some areas of East Asia. To investigate the environmental occurrence of GII in South Korea, we collected water samples from coastal streams and a neighboring waste water treatment plant in North Jeolla province (in March, July, and December of 2015)...

Viral acute gastroenteritis (AGE) is a major cause of mortality in childhood and leads to hospitalization in developing countries. Human bocavirus (HBoV) is a newly described virus associated with gastroenteritis. However, little is known about the clinical and epidemiological profile of human bocavirus (HBoV) in pediatric population in Chengdu, China. Between January 2012 and December 2013, 346 fecal samples from children admitted to hospital with acute gastroenteritis were tested for the presence of HBoV as well as other gastroenteritis viruses...
