Members of the Bifidobacteriaceae family represent both dominant microbial groups that colonize gut various animals, especially during suckling stage their life, while they also occur as pathogenic bacteria urogenital tract. The pan-genome genus Bifidobacterium has been explored in detail recent years, though genomics not yet received much attention. Here, a comparative genomic analyses 67 (sub) species including all currently recognized genera this family, i.e., Aeriscardovia,...
Abstract Studies so far conducted on irritable bowel syndrome (IBS) have been focused mainly the role of gut bacterial dysbiosis in modulating intestinal permeability, inflammation, and motility, with consequences quality life. Limited evidences showed a potential involvement fungal communities. Here, microbiota cohort IBS patients characterized compared that healthy subjects (HS). The microbial community structure differed significantly to HS. In particular, we observed an enrichment taxa...
Monarda spp. are promising Lamiaceae due to essential oil (EO) composition and antimicrobial activity. To investigate these properties, didyma M. fistulosa were grown for two years in Italian sites EO extraction (distillation), analysis (GC GC/MS), activity (microplate diffusion broth method). yield greatly increased from first second year of cultivation (0.27 0.51% 2013 2014, respectively), showing minor differences between fistulosa. Conversely, significantly varied the species years. Of...
In a previous study on bifidobacterial distribution in New World monkeys, six strains belonging to the Bifidobacteriaceae were isolated from faecal samples of baby common marmosets (Callithrix jacchus L.). All isolates Gram-positive-staining, anaerobic, asporogenous and fructose-6-phosphate phosphoketolase-positive. Comparative analysis 16S rRNA gene sequences revealed relatively low levels similarity (maximum identity 96 %) members genus Bifidobacterium, placed three independent clusters:...
Bifidobacterium has a diverse host range and shows several beneficial properties to the hosts. Many species should have co-evolved with their hosts, but phylogeny of is dissimilar that animals. The discrepancy could be linked niche-specific evolution due hosts’ dietary carbohydrates. We investigated relationship between bifidobacteria diet using comparative genomics approach. Since carbohydrates are main class nutrients for bifidobacterial growth, we examined distribution carbohydrate-active...
The essential oils (EOs) of Origanum compactum and Satureja montana chemotyped (CT) at carvacrol, two Thymus vulgaris CT thujanol thymol, Hydrolates (Hys) S. Citrus aurantium var. amara were chosen for studying their bactericidal efficacy against few phytobacterial pathogens. Minimal Inhibitory Concentration (MIC) Bactericidal (MBC) found by microdilution assay. O. (MBC 0.06% v/v), T. thymol Hy C. 6.25% v/v) resulted in being the most effective Erwinia amylovora; thus, they used as starting...
Despite the constant presence of members Bifidobacteriaceae in human oral cavity, few studies their occurrence this habitat have been made. The and distribution plaque dental caries <i>Bifidobacterium dentium</i>, <i>Scardovia inopinata</i> <i>Parascardovia denticolens,</i> all belonging to family Bifidobacteriaceae, were studied. identification species level was based on morphological growth type features, fermentation tests, polyacrylamide gel...
Abstract Here, we investigated the possible linkages among geophagy, soil characteristics, and gut mycobiome of indri ( Indri ), an endangered lemur species able to survive only in wild conditions. The eaten by resulted enriched secondary oxide-hydroxides clays, together with a high concentration specific essential micronutrients. This could partially explain role detoxification as nutrient supply. Besides, found that subject geophagy indris’ faeces shared about 8.9% fungal OTUs. Also,...
The extensive use of antibiotics has contributed to the current antibiotic resistance crisis. Livestock infections
The species Bifidobacterium longum currently comprises four subspecies: B. subsp. , infantis suis and suillum . Recently, several studies on suggested the presence of a separate clade containing strains isolated from infants one rhesus macaque. These shared phylogenetic similarity to DSM 20210 T JCM1995 [average nucleotide identity (ANI) 98.1 %) while showed an ANI 96.5 % with both current work describes five novel additional Bangladeshi weaning demonstrates their common origin those...
Folate (the general term for all bioactive forms of vitamin B9) plays a crucial role in the evolutionary highly conserved one-carbon (1C) metabolism, network including central reactions such as DNA and protein synthesis methylation macromolecules. delivers 1C units, methyl formyl, between reactants. Plants, algae, fungi, many bacteria can naturally produce folate, whereas animals, humans, must obtain folate from external sources. For deficiency is, however, widespread problem. Bifidobacteria...
Six Gram-positive-staining, microaerophilic, non-spore-forming, fructose-6-phosphate phosphoketolase-positive bacterial strains with a peculiar morphology were isolated from faecal samples of baby common marmosets (Callithrix jacchus). Cells these showed not reported previously for bifidobacterial species, which resembled coiled snake, always or ring shaped forming 'Y' shape. Strains MRM 3/1(T) and 4/2 chosen as representative characterized further. The bacteria utilized wide range...
Four Gram-positive-staining, microaerophilic, non-spore-forming, fructose-6-phosphate phosphoketolase-positive bacterial strains were isolated from a faecal sample of 5-year-old ring-tailed lemur ( Lemur catta ). The showed peculiar morphology, resembling small coiled snake, ring shape, or forming little ‘Y’ shape. appeared identical, and LMC 13 T was chosen as representative strain characterized further. Strain an A3β peptidoglycan type, similar to that found in Bifidobacterium longum . DNA...
In our previous study based on hsp60 PCR-restriction fragment length polymorphism and 16S rRNA gene sequencing, we stated that the bifidobacterial strains isolated from individual faecal samples of five baby common marmosets constituted different phylogenetically groups genus Bifidobacterium. study, also proposed these potentially represented novel species Out them, Bifidobacterium aesculapii, myosotis, tissieri hapali, have been described recently. Another strain, designated MRM 8.19T, has...
