Sixty-four rabbits (M91 meatline, both sexes) were divided into three experimental: E (EntM), S (sage), E + S (EntM + sage) groups and control group (C).

Enterococci Isolated from Trout in the Bukovec Water Reservoir and Čierny Váh River in Slovakia and Their Safety Aspect.

The aim of this study was to investigate enterococci as lactic acid bacteria and as part of Firmicutes phylum. We focused on the virulence factor, biofilm formation, and antibiotic resistance and also on lactic acid production and enterocin gene detection. Intestinal samples were taken from 50 healthy trout (3 and 47 ) collected in April 2007, 2010, and 2015 from different locations at the Bukovec water reservoir and the Čierny Váh River in Slovakia.

Some safety aspects of enterococci isolated from Slovak lactic acid dairy product "žinčica".

In Slovakia, dairy products made from ewes' milk have a long tradition. These products include the lactic acid product called "žinčica" which is a by-product occurring during the preparation of ewes' lump cheese. There is no information in the literature regarding the special properties of the microbiota, especially lactic acid Firmicutes, which can survive in "žinčica.

Relation to enterocins of variable Aeromonas species isolated from trouts of Slovakian aquatic sources and detected by MALDI-TOF mass spectrometry.

Aeromonads represent bacteria thought to be primarily mostly autochthonous to aquatic environments. This study was focused on the relation with antibiotics and enterocins of identified Aeromonas species isolated from the intestine of trouts living in Slovakian aquatic sources. Intestinal samples from 50 trouts (3 Salmo trutta and 47 Salmo gairdnerii) were collected in April of years 2007, 2010, and 2015 from trouts of different water sources in Slovakia (pond Bukovec near Košice, river Čierny Váh).

Enterocin M and its Beneficial Effects in Horses-a Pilot Experiment.
