The immune response modulated by inoculation of commensal bacteria at birth impacts the gut microbiota and prevents Salmonella colonization

Florent Kempf, Rosanna Drumo, Anne‐Marie Chaussé, Pierrette Menanteau et autres

Super- and low-shedding phenomena have been observed in genetically homogeneous hosts infected by a single bacterial strain. To decipher the mechanisms underlying these phenotypes, we conducted an experiment with chicks infected with Salmonella Enteritidis in a non-sterile isolator, which prevents bacterial transmission …

In vitro characterization of lactic acid bacteria and bifidobacteria from wild and domestic pigs: probiotic potential for post-weaning piglets

Kateřina Kavanová, Iveta Kostovová, Monika Morávková, Tereza Kubasová et autres

BACKGROUND: Gastrointestinal diseases in weaned piglets are a frequent cause of high morbidity and mortality in domestic pigs. The use of antibiotics is problematic due to increasing antibiotic resistance in bacterial populations, for which reason the use of suitable probiotics is highly …

Comparative Genome Analysis and Characterization of the Probiotic Properties of Lactic Acid Bacteria Isolated from the Gastrointestinal Tract of Wild Boars in the Czech Republic

Kateřina Kavanová, Iveta Kostovová, Monika Morávková, Tereza Kubasová et autres

Probiotics are crucial components for maintaining a healthy gut microbiota in pigs, especially during the weaning period. Lactic acid bacteria (LAB) derived from the gastrointestinal tract of wild boars can serve as an abundant source of beneficial probiotic strains with suitable properties …

Antibiotic Susceptibility, Resistance Gene Determinants and Corresponding Genomic Regions in Lactobacillus amylovorus Isolates Derived from Wild Boars and Domestic Pigs

Monika Morávková, Iveta Kostovová, Kateřina Kavanová, Radko Pechar et autres

Restrictions on the use of antibiotics in pigs lead to the continuous search for new probiotics serving as an alternative to antibiotics. One of the key parameters for probiotic bacteria selection is the absence of horizontally transmissible resistance genes. The aim of …

Succession, Replacement, and Modification of Chicken Litter Microbiota

Tereza Kubasová, Marcela Faldynová, Magdaléna Crhánová, Daniela Karasová et autres

Despite intimate contact, the composition of bedding, litter, and cecal microbiota differs considerably. Species characteristic for litter microbiota at different time points of chicken production were identified thus opening the possibility for active manipulation of litter microbiota.

Host Species Adaptation of Obligate Gut Anaerobes Is Dependent on Their Environmental Survival

Daniela Karasová, Marcela Faldynová, Jitka Matiasovicova, Alena Šebková et autres

The gut microbiota of warm-blooded vertebrates consists of bacterial species belonging to two main phyla; Firmicutes and Bacteroidetes. However, does it mean that the same bacterial species are found in humans and chickens? Here we show that the ability to survive in …

Probiotic Lactobacilli Do Not Protect Chickens against Salmonella Enteritidis Infection by Competitive Exclusion in the Intestinal Tract but in Feed, Outside the Chicken Host

Helena Juřicová, Jitka Matiasovicova, Marcela Faldynová, Alena Šebková et autres

Lactobacilli are commonly used as probiotics in poultry to improve production parameters and to increase chicken resistance to enteric infections. However, lactobacilli do not efficiently colonise the chicken intestinal tract, and also, their anti-infection effect in vivo is sometimes questionable. In this …

Eggshell and Feed Microbiota Do Not Represent Major Sources of Gut Anaerobes for Chickens in Commercial Production

Jiřı́ Volf, Magdaléna Crhánová, Daniela Karasová, Marcela Faldynová et autres

In this study, we addressed the origin of chicken gut microbiota in commercial production by a comparison of eggshell and feed microbiota with caecal microbiota of 7-day-old chickens, using microbiota analysis by 16S rRNA sequencing. In addition, we tested at which timepoint …

Ecological Adaptations of Gut Microbiota Members and Their Consequences for Use as a New Generation of Probiotics

Tereza Kubasová, Zuzana Seidlerová, Ivan Rychlı́k

In this review, we link ecological adaptations of different gut microbiota members with their potential for use as a new generation of probiotics. Gut microbiota members differ in their adaptations to survival in aerobic environments. Interestingly, there is an inverse relationship between …

The distribution of antibiotic resistance genes in chicken gut microbiota commensals

Helena Juřicová, Jitka Matiasovicova, Tereza Kubasová, Darina Čejková et autres

Antibiotic resistance in bacterial pathogens or several indicator bacteria is commonly studied but the extent of antibiotic resistance in bacterial commensals colonising the intestinal tract is essentially unknown. In this study, we aimed to investigate the presence of horizontally acquired antibiotic resistance …
