Bacterial flora of the intestine in normal captive oriental white storks

A survey was conducted to examine the normal intestinal bacterial flora of captive Oriental white storks (Ciconia boyciana) maintained at the Korea Institute of Oriental White Stork Rehabilitation Research, Cheongwon, South Korea. From the cloaca of 44 healthy storks, 44 fecal samples were collected and cultured under aerobic and anaerobic conditions. The 16S ribosomal RNA gene sequences and the heat shock protein 60 gene were cloned and sequenced for bacterial identification. Under aerobic conditions, Enterococcus faecalis, Escherichia coli, Bacillus spp., Enterococcus avium, Enterococcus gallinarum, Pseudomonas spp., Alcaligenes spp., Enterobacter spp., Corynebacterium spp., and Proteus mirabilis were identified. Under anaerobic conditions, E. coli, Clostridium tertium, En. faecalis, and P. mirabilis were identified. E. coli, En. faecalis, or both were isolated from all samples. These results will add to the information available on this stork species and help for the interpretation of fecal culture results.
