Lactobacilli colonizing the rectum may be a reservoir for vaginal lactobacilli. In a cross-sectional study of 531 females, vaginal and rectal colonization by lactobacilli were assessed by culture methods. A subset of isolates was identified to the species level by use of whole-chromosomal DNA probes. Lactobacillus crispatus (16%), L. jensenii (10%), and L. gasseri (10%) were the prevalent lacto...

BACKGROUND Lactobacilli are non-spore forming, lactic acid producing, gram-positive rods. They are a part of the normal gastrointestinal and genitourinary microbiota and have rarely been reported to be the cause of infections. Lactobacilli species are considered non-pathogenic organisms and have been used as probiotics to prevent antibiotic associated diarrhea. There are sporadic reported cases...

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...

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 (...

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...

lactic acid bacteria are characterized as gram-positive, usually non-motile, non-sporulating bacteria that produce lactic acid as a major or sole product of their fermentative metabolism. in this study, the presence of lactobacilli were investigated in the intestines of beluga ( huso huso) and persian sturgeon ( acipenser persicus ), inhabiting caspian sea. the obtained data showed that various...

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...

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...

Cereal grains are often included in equine diets. When starch intake exceeds foregut digestion starch will reach the hindgut, impacting microbial ecology. Probiotics (e.g., lactobacilli) are reported to mitigate GI dysbioses in other species. This study was conducted to determine the effect of exogenous lactobacilli on pH and the growth of amylolytic and lactate-utilizing bacteria. Feces were c...
