“…Close similarity could be found between strains from different epidemiological resources, and even within the same host species, such as the tree shrews in this study, and characteristics of high genetic diversity in the isolates were also identified. This unexpected result contradicted previous studies, and several studies have indicated that microorganism specificity to their hosts supports the co-evolution of the host and its microbes [51][52]. However, comparative genomics of the Proteus spp.…”

Proteus spp. are commensal gastrointestinal bacteria in many hosts, but information regarding the mutual relationships between these bacteria and their hosts is limited. The tree shrew is an alternative laboratory animal widely used for human disease research. However, little is known about the relationship between Proteus spp. and tree shrews. In this study, the complete genome sequencing method was used to analyse the characteristics of Proteus spp. isolated from tree shrews, and comparative genomic analysis was performed to reveal their relationships. The results showed that 36 Proteus spp. bacteria were isolated, including 34 Proteus mirabilis strains and two Proteus vulgaris strains. The effective rate of sequencing was 93.53%±2.73%, with an average GC content of 39.94%±0.25%. Briefly, 3682.89±90.37, 2771.36±36.01 and 2832.06±42.49 genes were annotated in the NCBI non-redundant nucleotide database (NR), SwissProt database and KEGG database, respectively. The high proportions of macrolide-, vancomycin-, bacitracin-, and tetracyclineresistance profiles of the strains were annotated in the Antibiotic Resistance Genes Database (ARDB). Flagella, lipooligosaccharides, type 1 fimbriae and P fimbriae were the most abundantly annotated virulence factors in the Virulence Factor Database (VFDB). SNP variants indicated high proportions of base transitions (Ts), homozygous mutations (Hom) and non-synonymous mutations (Non-Syn) in Proteus spp. (P<0.05). Phylogenetic analysis of Proteus spp. and other references revealed high genetic diversity for strains isolated from tree shrews, and host specificity of Proteus spp. bacteria was not found. Overall, this study provided important information on characteristics of genome for Proteus spp. isolated from tree shrews.

“…For identification of the species within the L. johnsonii cluster, whole-genome sequencing was performed for 31 isolates (16 from Scotland and 15 from France). Sequences of selected housekeeping genes were used to compare isolates with publicly available sequences of L. johnsonii, L. gasseri, and L. taiwanensis using a Multi-locus Sequence Typing (MLST) approach developed for L. johnsonii [21]. As expected, these three species formed distinct phylogenetic clusters (Fig.…”

“…The two taxa that consistently dominate Lactobacillus population in the murine gut in both molecular and culture-based studies are L. reuteri and closely related species of the L. johnsonii cluster (e.g., L. johnsonii and L. taiwanensis) [16][17][18][19][20]. Both L. reuteri and L. johnsonii have been shown to be composed of host-specific subpopulations [10,21] and partition resources during gut colonization [22]. These findings suggest a long-term tripartite evolutionary relationship between these two lineages and their rodent host.…”

The evolution of ecological facilitation within mixed-species biofilms in the mouse gastrointestinal tract

et al. 2018

The eco-evolutionary interactions among members of the vertebrate gut microbiota that ultimately result in host-specific communities are poorly understood. Here we show that Lactobacillus reuteri coexists with species that belong to the Lactobacillus johnsonii cluster (L. johnsonii, L. gasseri, and L taiwanensis) in a taxonomically wide range of rodents, suggesting cohabitation over evolutionary times. The two dominant Lactobacillus species found in wild mice establish a commensalistic relationship in gastric biofilms when introduced together into germ-free mice in which L. reuteri facilitates colonization of L. taiwanensis. Genomic analysis revealed allopatric diversification in strains of both species that originated from geographically separated locations (Scotland and France). Allopatry of the strains resulted in reduced formation of mixed biofilms in vitro, indicating that interspecies interactions in gastric Lactobacillus-biofilms are the result of an adaptive evolutionary process that occurred in a biogeographical context. In summary, these findings suggest that members within the vertebrate gut microbiota can evolve inter-dependencies through ecological facilitation, which could represent one mechanism by which host-specific bacterial communities assemble across vertebrate species and an explanation for their spatial and biogeographic patterns.

Comportamiento alimenticio de lechones en predestete dosificados vía oral con inóculos bacterianos del tracto digestivo del lechónFeeding behavior of pre-weaned piglets dosed orally with bacteria of the digestive tract of the piglet RESUMENSe evaluó el efecto alimenticio de la administración oral de inóculos de bacterias ácido láctico (BAL) nativas, extraídos y aisladas del tracto digestivo de un lechón e 21 días de edad. Los inóculos evaluados fueron mezclas en proporciones iguales de Lactobacillus johnsonii, Lactobacillus brevis, Enterococcus hirae y Pediococcus pentosaceus y dosificadas en concentraciones obtenidas mediante densidad óptica de 1,5x10 8 , 3x10 8 y 4,5x10 8 UFC/ml, fue administrado vía oral a 36 lechones de 14 días de edad y una semana antes del destete (nueve lechones por tratamiento). No hubo diferencias significativas en ganancia diaria de peso; sin embargo, el índice de conversión alimenticia fue mejor en los tres tratamientos con inoculo (p < 0,05), específicamente el tratamiento que contenía 3x10 8 UFC/ml. Se concluye que los inóculos bacterianos nativos aplicados vía oral tuvieron un efecto positivo en la conversión alimenticia en el predestete de lechones.Palabras clave: bacterias ácido lácticas; inóculo bacteriano; bacterias nativas; destete. ABSTRACTThe nutritional effect of oral administration of inoculums of native lactic acid bacteria (BAL), extracted and isolated from the digestive tract of a piglet and 21 days of age, was evaluated. The evaluated inoculums were mixtures of Lactobacillus johnsonii, Lactobacillus brevis, Enterococcus hirae and Pediococcus pentosaceus in equal proportions and dosed at concentrations measured by optical density of 1,5x10 8 , 3x10 8 and 4,5x10 8 CFU / ml orally given to 36 piglet of 14 day and one week before weaning (nine piglets per treatment). There were no significant differences in daily weight gain; However, the feed conversion index was better in the three treatments with inoculum (p < 0.05), specifically the treatment containing 3x10 8 CFU / ml. It is concluded that native bacterial inoculums applied orally had a positive effect on feed conversion in the pre-weaned of piglets.
