Abstract: The aim of this study was to compare, using culture methods, the microflora of the small and large intestines, distinguishing pathogenic bacteria, in free-living ruminants: roe deer (Capreolus capreolus) and red deer (Cervus elaphus). Intestinal samples from six individuals of each species were collected immediately after hunting under aseptic conditions. Aerobic and facultatively anaerobic bacteria, including Lactobacillus spp., Escherichia coli, Listeria spp., and Clostridium perfringens, were quantified using standard culture methods. Statistical analysis (ANOVA) revealed no significant differences (p > 0.05) between species in any of the microbial groups analyzed, although higher mean abundances were observed in red deer, particularly in the large intestine. The results indicate that interspecific variation in cultured microbiota may reflect individual and environmental factors rather than consistent taxonomic differences. Due to the high inter-individual variability and limited sample size, this study should be considered preliminary. The results demonstrate the predominance of viable aerobic and facultative anaerobic bacterial groups in culture-based analysis and provide reference data for future metagenomic studies. This study fills an important knowledge gap, as culture-dependent studies of the gut microbiota of wild cervids are still rare due to the logistical and ethical constraints associated with sampling wild animals.
