AIM To analyze the changes of different Lactobacillus species in ulcerative colitis patients and to further assess the therapeutic effects of selected Lactobacillus strains on dextran sulfate sodium (DSS)-induced experimental colitis in BALB/c mice. METHODS Forty-five active ulcerative colitis (UC) patients and 45 population-based healthy controls were enrolled. Polymerase chain reaction (PCR...

BACKGROUND Data regarding antimicrobial susceptibility of clinical Lactobacillus isolates are scarce, and appropriate interpretation criteria for susceptibility tests are not available. METHODS We examined 85 cases of Lactobacillus bacteremia, of which 47 cases have been included in our previous studies. Overall, 14 antimicrobial agents were evaluated by the E-test method, and these results w...

Potential fructophilic characteristics of Lactobacillus apinorum, originally isolated from the guts of honeybees (Apis mellifera), were studied in the present study. The species showed typical fructophilic growth characteristics, i.e., active growth on d-fructose, poor growth on d-glucose, and accelerated growth on d-glucose in the presence of electron acceptors. Biochemical characteristics str...

We previously discovered a symbiotic lactic acid bacterial (LAB) microbiota in the honey stomach of the honeybee Apis mellifera. The microbiota was composed of several phylotypes of Bifidobacterium and Lactobacillus. 16S rRNA gene sequence analyses and phenotypic and genetic characteristics revealed that the phylotypes isolated represent seven novel species. One grouped with Lactobacillus kunke...

The taxonomic positions of species of the Lactobacillus casei group have been evaluated by sequencing and phylogenetic analysis of a 277 bp recA gene fragment. High sequence similarity between strain ATCC 393T, currently designated as the type strain of L. casei, and the type strain of Lactobacillus zeae, LMG 17315T, has been established, while L. casei ATCC 334 and Lactobacillus paracasei NCDO...

Puba or carimã is a Brazilian staple food obtained by spontaneous submerged fermentation of cassava roots. A total of 116 lactobacilli and three cocci isolates from 20 commercial puba samples were recovered on de Man, Rogosa and Sharpe agar (MRS); they were characterized for their antagonistic activity against foodborne pathogens and identified taxonomically by classical and molecular methods. ...

Here, we report the draft genome sequences of two type strains of Lactobacillus, Lactobacillus farraginis JCM 14108(T) and Lactobacillus composti JCM 14202(T), isolated from the compost of distilled shōchū residue. Their genome information will be useful for studies of ecological and physiological functions of these Lactobacillus species.

Intrinsic resistances to tetracycline, vancomycin and erythromycin are common in Lactobacillus species; however, resistance to streptomycin, clindamycin, gentamicin, oxacillin and lincosamide is also reported in these species. Resistant markers tet(W), tet(M) and erm(B) have been frequently detected in the resistant strains while van(A), lnu(A) and tet(L) have also been found in some strains of...

Three heterofermentative lactic acid bacteria, obtained from Greek and Belgian artisanal wheat sourdoughs, were preliminarily identified as Lactobacillus brevis-like after screening using whole-cell protein fingerprinting and 16S rRNA gene sequence analysis. The three sourdough isolates showed nearly identical sequences (>99.7 % sequence similarity), and highest similarities of 98.2 and 97.6 % ...

Ghee is widely produced from a traditional fermented butter-like product named mashita in western Uganda. However, no detailed studies have been done to identify the microorganisms involved in mashita fermentation. The aim of this study was to identify the microorganisms present at the end of mashita ripening using culture-dependent and culture-independent techniques. The most commonly identifi...
