| Popis: | Background: The genome of the bacteria has considerable diversity in terms of sequence of nucleotide bases and change over the time. With the advancement of bioinformatics science possibility of the vast comparison to living organisms has risen. During the last two decades many information about genome sequencing of pathogenic and non-pathogenic bacteria have been published. Using this information and to find connections between them and many phenotypic characteristics and behavior of bacteria could be used in many studies. In this study we compared some of the genetic, phenotypic and behavioral properties of archaebacteria and eubacteria. Methods: In this analytical study, genomic Information of 286 species of archaebacteria and 122 species of eubacteria were collected from the NCBI (National Center for Biotechnology Information) site which was conducted in April to June 2015. Mean of gene size, gene number, protein number and C+G content compared in the two groups of archaebacteria and eubacteria. Association of genomic characterization of bacteria with several other characteristics were analyzed using SPSS statistical software version 19 (Chicago, IL, USA). For this purpose, the Pearson correlation coefficient (Pearson), Student’s t-test and ANOVA test (One-way analysis of variance) was used. The P values less than 0.05 was considered as significant level. Results: There was significant association between means discrepancy in two group (P= 0.01). The genome size of eubacteria and archaebacteria have significant association with some of the characteristics of bacteria, such as the C+G content, the number of proteins, genes and habitats of the bacteria (P= 0.01). As well as there was significant association between genome size and features such as number of pseudogene, mobility and type of breathing in eubacteria (P= 0.01) but not in archaebacterial (P˃ 0.05). Conclusion: Many characteristics of eubacteria and archaebacteria are significantly associated with genomic properties. Comparison genomics of bacteria will help in identification of evolutionary origins as well as differences between different categories of bacterial. |
