The faecal flora of the giant panda (Ailuropoda melanoleuca)

The faecal floras of two adult (male and female) and one infant (male) giant panda kept at the Ueno Zoo, Tokyo, Japan were examined and shown to be quite different from those of other animals. The predominant bacteria in the adults were Streptococcus (including Enterococcus) and Enterobacteriaceae, while obligate anaerobes had minor populations. Fastidious anaerobes were not detected. The predominant bacteria in the suckling infant were Lactobacillus and Streptococcus, followed by Bifidobacterium. After the infant began to eat bamboo leaves the number of Lactobacillus decreased and Bifidobacterium became undetectable, whereas Enterobacteriaceae became one of the most predominant flora. The most dominant streptococcus isolated from the female panda was identified as Streptococcus bovis, but those from the male adult and the weaned infant were not identified as any known species.
