Journal ArticleDOI
Succession and replacement of bacterial populations in the caecum of egg laying hens over their whole life.

TL;DR: The development of caecal microbiota in egg laying hens over their commercial production lifespan, from the day of hatching until 60 weeks of age, was characterised using pyrosequencing of V3/V4 variable regions of 16S rRNA genes for microbiota characterisation.
Journal ArticleDOI
Whole genome sequences of three Treponema pallidum ssp. pertenue strains: yaws and syphilis treponemes differ in less than 0.2% of the genome sequence.
Darina Čejková,Marie Zobaníková,Lei Chen,Lei Chen,Petra Pospíšilová,Petra Pospíšilová,Michal Strouhal,Michal Strouhal,Xiang Qin,Lenka Mikalová,Steven J. Norris,Donna M. Muzny,Richard A. Gibbs,Lucinda Fulton,Erica Sodergren,Erica Sodergren,George M. Weinstock,George M. Weinstock,David Šmajs +18 more
TL;DR: Hypothetical genes, with genetic differences, consistently found between TPE and TPA strains are candidates for syphilitic treponemes virulence factors and represent suitable targets for subspecies- and strain-specific molecular diagnostics.
Journal ArticleDOI
Whole genome sequencing and function prediction of 133 gut anaerobes isolated from chicken caecum in pure cultures.
Matej Medvecky,Darina Čejková,Ondrej Polansky,Daniela Karasova,Tereza Kubasova,Alois Cizek,Ivan Rychlik +6 more
TL;DR: Major gut microbiota members utilise different strategies for gut colonisation and high oxygen sensitivity of Firmicutes may explain their commonly reported decrease after oxidative burst during gut inflammation.
Journal ArticleDOI
Contact with adult hen affects development of caecal microbiota in newly hatched chicks.
Tereza Kubasova,Miloslava Kollarcikova,Magdalena Crhanova,Daniela Karasova,Darina Čejková,Alena Sebkova,Jitka Matiasovicova,Marcela Faldynova,Alexandra Pokorna,Alois Cizek,Ivan Rychlik +10 more
TL;DR: It was found that a mere 24-hour-long contact between a hen and newly hatched chickens was long enough for transfer of hen gut microbiota to chickens.
Journal ArticleDOI
Characterization of egg laying hen and broiler fecal microbiota in poultry farms in Croatia, Czech Republic, Hungary and Slovenia
Petra Videnska,Masudur Rahman,Marcela Faldynova,Vladimir Babak,Marta Elsheimer Matulova,Estella Prukner-Radovčić,Ivan Krizek,Sonja Smole-Mozina,Jasna Kovac,Ama Szmolka,Béla Nagy,Karel Sedlar,Darina Čejková,Ivan Rychlik +13 more
TL;DR: The prevalence of selected antibiotic resistance genes and microbiota composition in feces of egg laying hens and broilers originating from 4 different Central European countries determined by real-time PCR and 16S rRNA gene pyrosequencing, respectively, was determined.
