AB  - Human noroviruses (HuNoV) are the dominant cause of viral gastroenteritis in all age groups worldwide. In this study, we investigated the effects of pomegranate peel extract (PPE) on the reduction of HuNoV in different food models, on surfaces of fresh produce (green onion and cherry tomato), in low-fat milk, and simulated gastrointestinal fluids. The antiviral efficacy of PPE against HuNoV was evaluated by quantifying the number of residual virus genomes using a quantitative reverse transcription PCR (qRT-PCR) assay. Pomegranate peel, considered as a waste product of industrial processing, is known for beneficial health effects and broad antimicrobial activity due to the high content of phenolic compounds and tannins. PPE showed significant antiviral properties against HuNoV both in phosphate-buffered saline (PBS) and simulated gastric fluid. The reduction of HuNoV by pomegranate juice was lower than with PPE, which could be attributed to the lower content of antimicrobial compounds. A pretreatment of cherry tomato and green onion surfaces with PPE significantly reduced the amount of HuNoV particles that adhered to those surfaces during subsequent virus suspension treatment. A detrimental effect of PPE on HuNoV structure was confirmed by transmission electron microscopy. Our results indicate that PPE is a natural antiviral agent effective against food-borne noroviruses.

AB  - Medicinal plant extracts (MPE) have a broad antimicrobial activity, including antiviral effects. In our study, eleven dry extract of ten different medicinal plant prepared with two solvents (5%, dimethyl sulfoxide (DMSO) and 30% ethanol in 5% DMSO) in different concentrations have been examined for anti-noroviral activity. The reduction of norovirus > 1 log10 genome equivalents (GE) has been obtained with 1 mg/mL of Aronia melanocarpa leaf extract (AMLE), dried wine Prokupac (WPE) and Hypericum perforatum extract (HyPE). Some of MPE i.e. HyPE, Aronia melanocarpa fruit extract (AMFE) and Punica granatum (PPE) showed better activity when dissolved in 30% ethanol with 5% DMSO. All results of anti-noroviral activity of tested MPE which achieve  lt  0.5 log10 GE are considered as not effective.

AB  - Human  noroviruses  are  predominant  cause  of  epidemic  and  sporadic  food-borne  gastroenteritis  in industrialized  countries.  Priority  food  categories,  vehicles  of  viruses  in  many  reported  outbreaks, beside  shellfish  are  food  of  plant  origin  including  berries,  lettuce,  tomatoes  and  green  onions.  These items, as  well  as  deli  ham  are often  components  of  many  ready-to-eat foods.   The  aim  of  this  study  was  to  assess  the  effect  of  different  food  matrices  on  norovirus  detection.  Stool sample  with  previously  determined  concentration  of  norovirus  GII  particles,  was  used  to  inoculate surface  of  lettuce,  tomatoes,  green  onions  and  deli  ham  slices.  For  virus  RNA  extraction  the  direct method  was  used  followed  by  RT-qPCR  assay  with  SYBR  green  one-step  kit  and  degenerate  MON primers  for  the  detection  of  GII  norovirus.  Obtained  mean  Ct  values  and  Ct  alterations  calculated  for each  level  of  inoculation  revealed  that  tomato  had  no  inhibitory  effect  on  NoV  GII  detection,  followed by  one  log  decrease  of  RT-PCRU  due  to  properties  of  green  onions,  and  two  log  decrease  for  lettuce and  deli  ham  slices. The  adsorption  of  viruses  to  different  solid  surfaces  depends  on  their  complexity  and  food  surface factors  such  as  presence  of  hydrophobic  domains  and  acid/base  groups,  virus  specific  ligands,  etc. This  is  important  since  many  fruits  and  vegetables  have  complex  surfaces  that  prevent  the  removal  of viruses  by  simple  washing  and may  decrease desiccation  effects  that  could  lead  to virus  inactivation.
