[The Bacteriodaceae flora in the faeces of pigs (author's transl)[].

A total of 180 Bacteroidaceae strains from the fecal specimens of 31 clinically healthy pigs aged 120 to 180 days from 4 farms were isolated in numbers of 10(8)-10(10) per gram feces and differentiated for their morphological, cultural and biochemical properties. 161 of these strains belonged to Bacteroides ruminicola and related species, 10 to B. fragilis ss. fragilis, 3 to B. fragilis ss. vulgatus, 4 to Fusobacterium necrogenes, 1 to F. mortiferum and 1 to a non-motile variant of F. novum. The taxonomic relationships between B. ruminicola and B. oralis are discussed.

[Studies on the composition of the fecal flora of healthy dogs with the special references of Lactobacillus flora and Bifidobacterium flora (author's transl)].

With the new method the fecal flora of 13 clinically healthy dogs aged 3 to 42 months was analysed qualitatively and quantitatively. It was characterized by that bacteroidaceae constituted the most prodominant flora, catenabacteria, streptococci, peptostreptococci, lactobacilli and bifidobacteria were the next most numerous, enterobacteria consisted the accompanying flora. The numbers of Clostridium perfringens were remarkably fluctuated and seem to be influenced by the composition of the food ingested by the host. The total cultivable counts averaged log 10.8 +/- 0.2/g. The composition of the Lactobacillus flora and Bifidobacterium flora in the feces of 34 dogs from 3 different age groups was analysed. In the feces of all age groups L. acidophilus, L. salivarius and L. fermenti with 9 different types were found. Within the lactobacilli L. acidophilus type VI c, L. salivarius type VI a and L. fermenti type IV b were most frequently found. L. acidophilus types VI c and XI, L. salivarius types VI a and VI b could not be placed in any established types of each species, and were described as new types. Bifidobacteria were regularly found in large numbers in the feces of dogs aged 2 to 24 months. B. adolescentis and B. pseudolongum consisted the main Bifidobacterium flora.

[The fecal flora of man. III. Communication: The composition of Lactobacillus flora of different age groups (author's transl)].

From fecal flora of 66 infants aged 3 to 220 days, 29 children aged 4 to 6 years, 42 adults aged 20 to 64 years and 21 senile persons aged 65 to 86 years, the Lactobacillus flora was analysed qualitatively and quantitatively. In the feces of babies only the resident lactobacilli (L. acidophilus, L. salivarius and L. fermenti) were found, while in the feces of children, adults and senile persons the resident lactobacilli as well as the transient lactobacilli (L. casei, L. plantarum, L. brevis, L. buchneri and L. lactis) were found simultaneously. Within the Lactobacillus species L. acidophilus type I, L. fermenti type IVa and L. salivarius type Ia were most frequently found in the feces of all age groups. In addition, L. acidophilus type X was also often found in the feces of senile persons. In connection with the numbers of species or types of lactobacilli in one fecal specimen, one or two species or types were demonstrated in 94,5% of positive cases of infants. With increasing age the numbers increased, especially more than three species or types were demonstrated in 85% of positive cases. In infants in 3 different clinics, clinic-specificities were demonstrated in relation to the species or types of lactobacilli isolated: in each clinic clearly certain species or types of lactobacilli were present. The results indicate that the composition of the Lactobacillus flora in the feces is influenced by lactobacilli orally ingested.
