Abstract:
... The main objective was to assess the effectiveness of preharvest application of chitosan (CH) and tea tree essential oil (TT) in butterhead lettuce in controlling native microflora growth and counteract exogenous Escherichia coli O157:H7 contamination. TT and CH were applied to lettuce plants at 14, 10, 7, 3 and 0 days before harvest. CH showed significant reductions at harvest on mesophilic (−2.0 ...

Abstract:
... Enterohemorrhagic Escherichia coli (EHEC) have been responsible for several outbreaks of hemolytic–uremic syndrome (HUS) worldwide. HUS is the most common cause of acute renal failure in children and results in fatalities as high as 50% in the elderly. Currently, neither a specific treatment nor a vaccine is available for EHEC. Lactococcus lactis is a generally regarded as safe “GRAS” bacterium th ...

Abstract:
... Direct-fed microbials (DFM) have been employed in ruminant production for over 30 yr. Originally, DFM were used primarily in young ruminants to accelerate establishment of the intestinal microflora involved in feed digestion and to promote gut health. Further advancements led to more sophisticated mixtures of DFM that are targeted at improving fiber digestion and preventing ruminal acidosis in mat ...
