Anaerobic Bacteroides species are dominant microbiota of the digestive tract of mammals. Along with other symbiotic bacteria located in the gastrointestinal tract, they contribute to the proper functioning of the organism. Some Bacteroides species are highly pathogenic. Virulence of these bacteria is related to their polysaccharide capsule, lipopolysaccharide and a variety of enzymes and enterotoxin. In recent years, an increase of antibiotic resistance in Bacteroides spp. has been noted

We evaluated the usefulness of the Carba NP test for rapid detection of carbapenemase activity in Bacteroides spp. The minimum inhibitory concentration (MIC) for imipenem was determined with gradient test strips, and cfiA gene was investigated by polymerase chain reaction for 27 clinical Bacteroides spp. isolates. Carba NP test was performed according to recommendations of the Clinical and Laboratory Standards Institute. Among three cfiA gene harboring clinical isolates, two imipenem resistant

structure of the two groups (vaginal delivery and cesarean section) in 3-day-old neonates and 30–42-day-old infants is shown in Fig. 1 and 2, respectively. As shown in Fig. 1, in the 3-day-old neonates, there were no significant differences in the levels of Escherichia-Shigella in the two groups (p > 0.05). The genera Bifidobacterium, Lactobacillus, and Bacteroides were more prominent in the vaginal delivery group than the cesarean section group, which had higher levels of Staphylococcus, Streptococcus

The growing number of children with overweight and obesity constitutes a major health problem of the modern world and it has been suggested that intestinal microbiota may influence energy intake from food. The objectives of this study were to determine quantity and proportions of dominant genera of Bacteroides, Prevotella (phylum Bacteroidetes); Clostridium, Lactobacillus (phylum Firmicutes) and Bifidobacterium (phylum Actinobacteria) in the intestines and to determine the content of short

abundance of Bacteroidetes or Firmicutes appeared to vary. Regarding genera, the populations of Bacteroides and Akkermansia decreased with increasing age.

method. Eight group of clones representing different restriction patterns were identified. The nucleotide sequences of their inserts suggest that bacteria present in the mine environment belong to: Flavobacteria, Sphingobacteriia, Bacteroides, Proteobacteria, Mollicutes and Firmicutes. The metagenomic approach allows to demonstrate a higher diversity of microbiota than classical microbiological studies of cultivable isolates.

, Ruminococcaceae, Paraprevotellaceae, Rikenellaceae, Alcaligenaceae and Coriobacteriaceae, genera Prevotella, Bacteroides, Roseburia, Faecalibacterium and Sutterella were statistically significant different species (P < 0.05) between white and red pitayas. These findings might be useful for growth improvement, fruit preservation and processing of different pitaya species from different origins.

genus level, 93 genera were obtained. The healthy group consists of 46 genera with four abundant genera (> 1% of the total DNA sequences), including Lactobacillus, Bacteroides, Alistipes, and Clostridium sensu stricto. There were 47 genera in the NKLA group with six abundant genera, and 59 genera in the KLA group with six abundant genera.
The linear discriminant analysis effect size (LEfSe) method was employed in this study to assess alterations in the composition of gastric mucosal microbiota in

The caecal chyme of pigs was incubated anaerobically in McDougall buffer with and without fumonisin B1 (5 μg/ml) for 0, 24 and 48 h. The plate count agar technique was applied for enumerating the amount of bacteria including aerobic, anaerobic bacteria, coliform, Escherichia coli and Lactobacillus sp. The quantitative polymerase chain reaction was also performed to estimate the number of copies of the total bacteria, Lactobacillus, Bacteroides and Prevotella. No significant differences in

Firmicutes increased significantly in the MDG group compared to the NC group (p = 0.01).
The four most prevalent bacterial genera in the guts of the NC and treatment groups were Alistipes, Alloprevotella, unidentified_Ruminococcaceae, and Bacteroides (Fig. 4). Compared to the NC group, Alistipes exhibited significantly decreased proportions in the HDG group (p = 0.038). In addition, the abundance of Candidatus_Saccharimonas decreased significantly in the MDG and HDG groups (p=0.01, p=0.007). By contrast
