Alloscardovia macacae sp. nov., isolated from the milk of a macaque (Macaca mulatta), emended description of the genus Alloscardovia and proposal of Alloscardovia criceti comb. nov.

A novel bacterial strain, designated M8(T), was isolated from milk of a female macaque bred in captivity. The strain was Gram-stain-positive, anaerobic, irregular coccoid-rod-shaped without catalase activity. Analysis of 16S rRNA gene sequence similarity revealed that the isolate was most closely related to Alloscardovia omnicolens CCUG 31649(T) (96.

Bifidobacterium animalis subsp. lactis strains isolated from dog faeces.

The aim of the study was to identify and characterize dog bifidobacterial isolates and compare them with commercial probiotic strains. Sixteen isolates of Bifidobacterium animalis ssp. lactis from dog faeces (German Shepherd Dog) were identified by subspecies-specific PCR, MALDI-TOF MS and sequencing.

Growth of infant fecal bacteria on commercial prebiotics.

Fecal bacteria from 33 infants (aged 1 to 6 months) were tested for growth on commercial prebiotics. The children were born vaginally (20) or by caesarean section (13). Bifidobacteria, lactobacilli, gram-negative bacteria, Escherichia coli, and total anaerobes in fecal samples were enumerated by selective agars and fluorescence in situ hybridization.

Growth and survival of lactic acid bacteria in lucerne silage.

A rifampicin-resistant variant of two strains of Lactobacillus plantarum, one strain of Pediococcus acidilactici, and one strain of Enterococcus faecium were used for the experimental production of lucerne silage. Laboratory silage without inoculants served as a control. Counts of total anaerobes, total lactic acid bacteria (LAB), lactobacilli, pediococci, and enterococci were determined on days 14, 21, 30, 49, and 60 of lucerne fermentation.

Inter-species differences in the growth of bifidobacteria cultured on human milk oligosaccharides.

Human milk (HM) contains as the third most abundant component around 200 different structures of human milk oligosaccharides (HMOs). HMOs are the first and irreplaceable prebiotics for infants, supporting bifidobacteria as the most important bacterial group in an infant intestine. The aim of our study was to test the growth of bifidobacteria in HM and on HMOs.
