OBJECTIVE To determine whether (1) a decreased concentration of Lactobacilli allows S. pyogenes to grow; (2) S. pyogenes is able to grow in the presence of healthy Lactobacillus concentrations; (3) S. pyogenes is capable of inhibiting Lactobacilli. METHODS One hundred fifty patient samples of S. pyogenes were mixed with four different concentrations of L. crispatus and L. jensenii. Colony cou...

lactobacilli, like the other gut commensal bacteria, are well known for their use in poultry nutrition and for their probiotic properties. however, little is known about their interaction with the gastro-intestinal tract when administered in vivo. to specifically monitor the passage of lactobacilli after administered in hatchery, lactobacillus plantarum was transformed with the recombinant vect...

This research aimed to evaluate goat milk rich in Omega-3 PUFA from animals fed extruded flaxseed as a raw material produce fermented using beneficial lactobacilli. Experimental milks were produced Lacticaseibacillus paracasei Shirota and two potential probiotic lactobacilli, namely rhamnosus A2 FS109. The goats basal diet without any supplementation (CON) supplemented with 200 g/d of linseed (...

We investigated the effects of Cu2+-loaded silicate (CLS) on the growth performance, microflora of skin, gill and intestine, and intestinal morphology of crucian carp Carassius auratus. A total of 225 native wild crucian carp, with an average initial body weight of 20 g, were randomly divided into 5 treatment groups using 3 replicate tanks of 15 fish per group. The dietary treatments were (1) b...

Inflammatory bowel disease (IBD) was regarded as a problem of the industrialised nations. However, with popularity and convenience connected to ultra-processed food, fast food restaurant dining, due lack appropriate strategies avoid foodborne microbes, started emerge in other parts world also. Bacterial imbalance, intestinal permeability, associated dysbiosis-caused polarization immune componen...

background: the aim of this study was to clarify the mechanism by which lactobacilli exert their cytotoxic effects on cervical cancer cells. in addition, we aimed to evaluate the effect of lactobacilli on the expression of human papilloma virus (hpv) oncogenes. materials and methods: in this experimental study, using quantitative real-time polymerase chain reaction (pcr), we analyzed the expres...

Previous animal studies have shown that the administration of probiotic Lactobacillus rhamnosus can provide a protective effect against ischemia/reperfusion and necrotic injury to the intestine, liver, and heart, as well as a therapeutic effect to the outcome of ischemic injury to the heart, including cardiac hypertrophy and heart failure. We hypothesized that L. rhamnosus GR-1 major secreted p...

trichomoniasis, a worldwide prevalent infection, is a perfect example of interplay between the infecting parasite and the host, on which the presentation of disease depends. to study the pathogenesis, animal model is required for establishment of infection. in this study, by using strains of trichomonas vaginalis isolated from vaginal swabs and/or urine samples and maintained in axenic form fro...

In the present study, an attempt has been made to assess the probiotic characteristics of lactobacilli and yeast strains isolated from whey beverage under conditions simulating the in vivo stresses encountered in the gastrointestinal tract i.e. acid, alkaline, proteolytic enzymes and bile stress. The therapeutic potential of probiotics Lactobacillus casei or Lactobacillus yoghurt was assessed i...

The probiotic properties of two selected lactobacilli strains were assessed. L. salivarius and L. plantarum displayed higher hydrophobicity (48% and 54%, resp.) and coaggregation ability with four pathogens (from 7.9% to 57.5%). L. salivarius and L. plantarum had good inhibitory effects on S. aureus (38.2% and 49.5%, resp.) attachment to Caco-2 cells. Live lactobacilli strains and their conditi...
