Many recent papers have deepened the state of knowledge about lactic acid bacteria (LAB) in fish gut. In spite of high variability in fish microbiota, LAB are sometimes abundant in the intestine, notably in freshwater fish. Several strains of Streptococcus are pathogenic to fish. Streptococcus iniae and Lactococcus garvieae are major fish pathogens, against which commercial vaccines are availab...

Gou and colleagues have conducted a systematic review and meta-analysis of randomized controlled trials to determine the effects of probiotics in the treatment of severe acute pancreatitis [1]. We congratulate and applaud their important work, but several important issues should be noted. First, in the 'Methods' subsection of the Abstract, the authors stated 'Eligible studies were randomized co...

an inactivated agalactia vaccine was prepared with mycoplasma agalactiae in fermenter. the culture was inactivated and subsequently adjuvanted with aluminum hydroxide gel. four sheep and four goats were immunized with the experimental vaccine. two doses of 1ml of vaccine were administered three weeks interval. monthly, blood samples were taken from the vaccinated animals up to the fifth month a...

BACKGROUND The colonic epithelium maintains a life long reciprocally beneficial interaction with the colonic microbiota. Disruption is associated with mucosal injury. AIMS We hypothesised that probiotics may limit epithelial damage induced by enteroinvasive pathogens, and promote restitution. METHODS Human intestinal epithelial cell lines (HT29/cl.19A and Caco-2) were exposed to enteroinvas...

BACKGROUND Competition of probiotic bacteria with other species from the intestinal microbiota involves different mechanisms that occur regardless of probiotics' viability. The objective of this paper was to assess the cytokine serum levels in holoxenic mice after oral administration of non-viable components (NVC) of Enterococcus faecium probiotic culture stimulated with heat-inactivated Escher...

The effects of the dietary administration of two heat-inactivated whole bacteria from the Vibrionaceae family, singly or combined, on innate immune response of the seabream were studied. The two bacteria (Pdp11 and 51M6), which were obtained from the skin of gilthead seabream, showed in vitro characteristics that suggested they could be considered as potential fish probiotics. The fish were fed...

Background: The effects of the dietary administration of two heat-inactivated whole bacteria from the Vibrionaceae family, singly or combined, on innate immune response of the rainbow trout were studied. The two bacteria (Pdp11 and 51M6), which were obtained from the skin of rainbow trout, showed in vitro characteristics that suggested they could be considered as potential fish probiotics. Meth...
