Three hundred Enterococcus isolates from the rumen and faeces of three sheep were analysed for antibiotic resistance. Resistance to tetracycline, kanamycin, and streptomycin was predominant, followed by erythromycin resistance. About 7% of the isolates were resistant to ampicillin and vancomycin only. All tested isolates were susceptible to chloramphenicol. The presence of selected antibiotic resistance determinants was tested by PCR. No tested β-lactamase resistance determinant was detected in ampicillin resistant lactamase positive isolates. Both tet(M) and tet(L) tetracycline resistance determinants were detected. While tet(M) was predominant in both rumen and faecal isolates, clearly a higher frequency of tet(L) determinant was observed in rumen isolates. Among erythromycin resistant isolates, the erm(B) gene was detected only. From this data, it may be concluded that genotypically different enterococcal populations dwell in the upper and lower parts of sheep gastrointestinal tract.

Hibernation is an extraordinary phenomenon evolved in many animals including some mammals, allowing them to survive unfavorable environmental conditions. This period represents a phase of fasting, which is known to affect the gut microflora in nonhibernating mammals. Since during hibernation the physiological parameters (e.g., body temperature) differ from values in nonhibernating individuals, the food starvation is not the only parameter affecting the gut microflora. However, little is known about gut microflora in hibernating mammals. This study is focused on the examination of the gut microflora of Mediterranean horseshoe bat (Rhinolophus euryale) during hibernation. Faecal samples were collected during the winter from November 2014 to March 2015 and subsequently subjected to cultivation, non-cultivation analyses and morphological examination. Cultivation analysis revealed that the numbers of total cultivable bacteria, enterobacteria and enterococci in the faecal samples decreased during the hibernation and restored to pre-hibernation numbers at the end of hibernation. Results of non-cultivation analysis showed time-dependent (but surprisingly almost not individual-specific) changes in the gut microflora and decrease in bacterial variability dependent on hibernation stage. Changes in microflora were accompanied by changes in faecal content identified by morphological analysis. Our results demonstrate that hibernation affects the gut microflora of bats in significant degree in both quantitative and qualitative scale

The Aerococcus viridans isolates from bovine mastitis in Slovakia were isolated and characterized by classical microbiological and biochemical, and molecular techniques including IGS-PCR and rep-PCR, ARDRA and 16S rDNA gene sequencing. The substantial variability of antibiotic resistance patterns was observed. The majority of strains were resistant to beta-lactam antibiotics, the resistance to tetracycline was observed in 3 tested strains, resistance to lincomycin was found in 4 strains and practically all tested strains were sensitive to neomycin and ciprofloxacin. While variable at a phenotypic level, no significant genetic variability among A. viridans isolates was detected by molecular DNA based methods. The data obtained suggest that a few A. viridans strains spread among cow's population in Slovak farms.
