Abstract Calf diarrhea is associated with enteric infections, and also provokes the overuse of antibiotics. Therefore, proper treatment represents a therapeutic challenge in livestock production public health concerns. Here, we describe ability fecal microbiota transplantation (FMT), to ameliorate restore gut microbial composition 57 growing calves. We conduct multi-omics analysis 450 longitudinally collected samples find that FMT-induced alterations (an increase family Porphyromonadaceae )...
Although several studies have identified a distinct gut microbial composition in Parkinson's disease (PD), few investigated the oral microbiome or functional alteration of PD. We aimed to investigate connection between and changes PD-specific using shotgun metagenomic sequencing. The taxonomic was significantly different PD patients healthy controls (P = 0.003 0.001, respectively). Oral Lactobacillus more abundant associated with opportunistic pathogens (FDR-adjusted P < 0.038). Functional...
Invertebrates are a very attractive subject for studying host-microbe interactions because of their simple gut microbial community and host diversity. Studying the composition invertebrate microbiota determining factors is essential understanding symbiotic mechanism. Cephalopods invertebrates that have similar biological properties to vertebrates such as closed circulation system, an advanced nervous well-differentiated digestive system. However, it not currently known whether microbiomes...
Two strains, VM2412T and VR2415T, were isolated from the feces of an Andean condor (Vultur gryphus) living in Seoul Grand Park, Gyeonggi-do, South Korea. Cells both strains observed to be Gram-stain positive, non-motile, aerobic, catalase positive oxidase negative. Growth was found occur at 10-30°C, showing optimum growth 30°C. The could tolerate up 15% (w/v) NaCl concentration grow pH 6-9. shared 99.3% 16S rRNA gene sequence similarity each other but identified as two distinct species based...
Neonatal calf diarrhea is a common disease leading to major economic loss for cattle producers worldwide. Several infectious and noninfectious factors are implicated in diarrhea, but control remains problematic because of the multifactorial etiology disease. Here, we conducted diagnostic multiplex PCR assay meta-omics analysis (16S rRNA gene-based metataxonomics untargeted transcriptional profiling) rectal content normal diarrheic beef calves (
A strictly anaerobic, Gram-stain-positive, non-motile and coccoid- or oval-shaped bacterium, designated strain KB1T, was isolated from a faecal sample of patient with diverticulitis in South Korea. Degeneracies the 16S rRNA gene sequence KB1T were resolved by cloning, which yielded five different sequences heterogeneity. Phylogenetic analysis based on showed that formed monophyletic branch species genus Blautia, highest similarity to type Blautia producta (97.7-98.9 %), followed coccoides...
Cultivation and isolation of gut bacteria are necessary for understanding their role in the intestinal ecosystem. We isolated a novel bacterium, designated strain BG01T, from faeces patient with Crohn's disease. Strain BG01T was strictly anaerobic, rod-shaped, Gram-variable endospore-forming bacterium. possessed C12 : 0, C18 0 dimethyl aldehyde (DMA) 1 ω9c DMA as predominant cellular fatty acids meso-diaminopimelic acid diagnostic diamino acid. grew at 15-45 °C (optimum, 37 °C), 0-4 % (w/v)...
A novel Gram-stain-negative, non-spore-forming, obligate aerobic, motile, rod-shaped, and flagellated bacterium, designated S11R28T, was isolated from the intestinal tract of a Korean shiner, Coreoleuciscus splendidus. Based on 16S rRNA gene sequences, strain S11R28T identified as member genus Undibacterium in class Betaproteobacteria, closely related to parvum DSM 23061T (98.49 %). The isolate grew at 4-25 °C, pH 6-9, with 0 % (w/v) NaCl, optimally 20 8, absence NaCl. main cellular fatty...
A polyphasic taxonomic approach was used to characterize two novel bacterial strains, designated as HDW11 T and HDW19 , isolated from intestine samples of the dark diving beetle Hydrophilus acuminatus Cybister lewisianus respectively. Both isolates were Gram-stain-positive, facultatively anaerobic non-motile. Strain grew optimally at 30 °C, pH 8 in presence 1% (w/v) NaCl. 25 7 0.3% Phylogenetic analysis based on 16S rRNA gene sequences genome revealed that strain is a member genus...
A novel Gram-negative, obligately aerobic, rod-shaped and non-motile bacterium, designated strain K13M18T, was isolated from the intestinal tract of a Korean indigenous fish, oily bitterling (Acheilognathus koreensis). Strain K13M18T formed creamy-pink colonies on marine agar plate. Results phylogenetic analysis based 16S rRNA gene sequence similarity indicated that most closely related to Tabrizicola sediminis DRYC-M-16T, sharing 97.62 % with strain. belonged genus Tabrizicola, which...
A Gram-stain-positive, facultatively aerobic, spore-forming, oxidase-positive, catalase- and DNase-negative, rod-shaped motile bacterial strain, AR23208T, was isolated from the gut of a cinereous vulture (Aegypius monachus), collected at Seoul Grand Park Zoo (Republic Korea). Strain AR23208T grew optimally 25-30 °C, pH 7 in absence NaCl. Phylogenetic analysis revealed that strain shared 98.2 97.1 % 16S rRNA gene sequence similarity with Tumebacillus algifaecis THMBR28T...
Kushneria konosiri X49T is a member of the Halomonadaceae family within order Oceanospirillales and can be isolated from salt-fermented larval gizzard shad. The genome K. reported here provides genetic basis for its halophilic character. Diverse genes were involved in salt-in -out strategies enabling adaptation to hypersaline environments. Due resistance high salt concentrations, research will contribute improvement environmental biotechnological usage by enhancing understanding osmotic...
A novel Gram-stain-negative, aerobic, rod-shaped, reddish-orange-coloured, gliding bacterial strain, designated L12M1T, was isolated from the gut of Korean scallop, Patinopecten yessoensis. Phylogenetic analysis based on 16S rRNA gene sequence revealed that strain L12M1T formed a monophyletic clade with strains in genus Flammeovirga and showed highest similarity to kamogawensis YS10T (98.66 %). The major cellular fatty acids were iso-C15 : 0 C20 4ω6,9,12,15c. predominant isoprenoid quinone...
A novel, Gram-stain-positive, non-spore-forming, facultatively anaerobic bacterium, designated strain H21T32 T , was isolated from the faeces of an Oriental stork, Ciconia boyciana .
