, a significant zoonotic pathogen, annually caused substantial economic losses in the swine industry and had intensified threat to public health due to the recent emergence of human-associated clade. In this study, we discovered that the rare-earth metal-based metal-organic frameworks (Y-BTC) possessed excellent ECL capabilities. After prereduction at high voltage, its ECL intensity was enhanced by two times.

Specialized Mining Company "Górtech" Sp. z o.o, ul. Wielicka 50, Krakow, 30-552, Poland.

Background: Diatomite is a source of biologically available silicon but in feed industry its insecticide and anti-caking properties have been also widely recognized. The aim of the study was to evaluate the effect of dietary diatomite-bentonite mixture (DBM) supplementation on the quantitative and qualitative composition of the bacterial microbiome of the broiler chicken gut. The trial was carried out on 960 Ross 308 broiler chickens divided into 2 experimental groups throughout the entire rearing period lasting 6 weeks.
