Whether p-bta- miR-3 observed in our study is an authentic miRNA of bacterial origin needs to be further tested.. To characterize the distinct DE miRNA profiles of the two bacterial strains we per- formed pathway analysis using IPA. For three of the ST12-unique DE miRNAs (bta-miR-155, bta-miR-125b and bta-miR-223) evidence of induction by bacteria has been previously documented.

Fifty-two bacterial strains which had been isolated in 2005–2006 from imported dairy products and identified using phenotyping as E. Ten of the ST13 strains had been isolated from PIF. The remaining strainsr were from dairy product ingredients (8), milk powder (7), cheese (5), and other dairy products (2). sakazakii ST4 strains (pathovar associated with neonatal meningitis) were from milk powder, cheese, other dairy products and dairy product ingredients.

Biological method was proved to be an effective method due to this practice containing bacterial strains which can concentrate suspended solid in water and removal nitrogen and phospho. In laboratory experiment, bio-liquid consisting of three good bio-flocculant bacterial strains [T2a, KT1 & P11] and three denitrifying and poly-P bacterial strains [N9b, 6Rc & LV1]) was used to treat sludge from trafish pond bottom.

BacTag - a pipeline for fast and accurate gene and allele typing in bacterial sequencing data based on database preprocessing

The genomic sequence is extracted from the genome of one of the target strains for the corresponding MLST schema (see Table 1). The sequencing data analysis part of the pipeline was validated by using artificial Illumina reads, based on the complete genomes of 30 different bacterial strains belonging to 13 different bacterial species (see Table 2), for which the alleles of housekeeping genes associated with the corresponding MLST schema were previously re- ported.

Inter-chromosomal k-mer distances

tailieu.vn

Results: After defining the various distance measures and summarizing their properties, we also define proximities that rely on the existence of synteny blocks between chromosomes of different bacterial strains. Comparing pairs of strains of bacteria, we find negative correlations between synteny proximities and k-mer distances, thus establishing the meaning of the latter as measures of evolutionary distances among bacterial strains. K-mer structural distances can be defined for all species.
