“…Species of Bifidobacterium have been isolated from the feces of adult and infant common marmosets ( Callithrix jacchus ; Endo, Futagawa‐Endo, Schumann, Pukall, & Dicks, ; Lugli et al, ; Michelini et al, ; Michelini, Oki et al, ; Modesto et al, ; Toh et al, ). As found in humans (Stewart et al, ; Yatsunenko et al, ), the relative abundance of bifidobacteria is highly variable between individuals and populations.…”

The genus Bifidobacterium is purported to have beneficial consequences for human health and is a major component of many gastrointestinal probiotics. Although species of Bifidobacterium are generally at low relative frequency in the adult human gastrointestinal tract, they can constitute high proportions of the gastrointestinal communities of adult marmosets. To identify genes that might be important for the maintenance of Bifidobacterium in adult marmosets, ten strains of Bifidobacterium were isolated from the feces of seven adult marmosets, and their genomes were sequenced. There were six B. reuteri strains, two B. callitrichos strains, one B. myosotis sp. nov. and one B. tissieri sp. nov. among our isolates. Phylogenetic analysis showed that three of the four species we isolated were most closely related to B. bifidum, B. breve and B. longum, which are species found in high abundance in human infants. There were 1357 genes that were shared by at least one strain of B. reuteri, B. callitrichos, B. breve, and B. longum, and 987 genes that were found in all strains of the four species. There were 106 genes found in B. reuteri and B. callitrichos but not in human bifidobacteria, and several of these genes were involved in nutrient uptake. These pathways for nutrient uptake appeared to be specific to Bifidobacterium from New World monkeys. Additionally, the distribution of Bifidobacterium in fecal samples from captive adult marmosets constituted as much as 80% of the gut microbiome, although this was variable between individuals and colonies. We suggest that nutrient transporters may be important for the maintenance of Bifidobacterium during adulthood in marmosets.

Forty-three strains of bifidobacteria were isolated from the faeces of two adult black lemurs, Eulemur macaco. Thirty-four were identified as Bifidobacterium lemurum, recently described in Lemur catta. The nine remaining isolates were Gram-positive-staining, non-spore-forming, fructose-6-phosphate phosphoketolase-positive, microaerophilic, irregular rod-shaped bacteria that often presented Y-or V-shaped cells. Typing techniques revealed that these isolates were nearly identical, and strain LMM_E3T was chosen as a representative and characterized further. T showed a peptidoglycan structure that has not been detected in bifidobacteria so far:Based on the phylogenetic, genotypic and phenotypic data, strain LMM_E3 T represents a novel species within the genus Bifidobacterium, for which the name Bifidobacterium eulemuris sp. nov. is proposed; the type strain is LMM_E3 T
