Journal ArticleDOI
Variation in honey bee gut microbial diversity affected by ontogenetic stage, age and geographic location.
Zuzana Hroncová,Jaroslav Havlik,Jiri Killer,Ivo Doskocil,Jan Tyl,Martin Kamler,Dalibor Titera,Josef Hakl,Jakub Mrázek,Vera Bunesova,Vojtech Rada +10 more
TL;DR: It is found that bacterial counts do not show only yearly cycles within a colony, but vary on the individual level, and redundancy analysis conducted using denaturing gradient gel electrophoresis identified bacterial species that were characteristic of each developmental stage.
Journal ArticleDOI
Bifidobacterium actinocoloniiforme sp. nov. and Bifidobacterium bohemicum sp. nov., from the bumblebee digestive tract.
TL;DR: Results indicate that the isolates of the two groups belong to novel species within the genus Bifidobacterium, as proposed by phylogenetic and phenotypic analyses and analysis of 16S rRNA and partial hsp60 gene sequences.
Journal ArticleDOI
Bifidobacterium bombi sp. nov., from the bumblebee digestive tract.
Jiří Killer,Jan Kopečný,Jakub Mrázek,Vojtech Rada,Oldřich Benada,I. Koppová,Jaroslav Havlik,Jakub Straka +7 more
TL;DR: The results presented support the proposal of a novel species to accommodate strain BluCI/TPT, with the name Bifidobacterium bombi sp.
Journal ArticleDOI
Bombiscardovia coagulans gen. nov., sp. nov., a new member of the family Bifidobacteriaceae isolated from the digestive tract of bumblebees
Jiří Killer,Jan Kopečný,Jakub Mrázek,Jaroslav Havlik,I. Koppová,Oldřich Benada,Vojtech Rada,Olga Kofroňová +7 more
TL;DR: In this article, a new genus of Bifidobacteriaceae, Bombiscardovia coagulans gen. nov., sp.Nov. (type strain=BLAPIII-AGV(T)=DSM 22924 (T)=ATCC BAA-1568(T)).
Journal ArticleDOI

TL;DR: Populus nigra and Betula pendula were identified as species with the highest xanthine oxidase inhibitory potential in this study, which correlates with the ethnobotanical data on their use in Central European folklore and provides the basis for further investigation on these plants.
