Comparative genome hybridization for Lactobacillus casei

ABSTRACT: Lactobacillus casei is remarkably adaptive to diverse habitats. To understand the evolution and adaptation of Lb. casei strains isolated from different environments, the gene content of 22 Lb. casei strains isolated from various habitats (cheeses, n=8; plant materials, n=8; and human sources, n=6) were examined by comparative genome hybridization with an Lb. casei ATCC 334-based microarray. Comparative genome hybridization was performed against an Affymetrix custom microarray designed to include 2,661 (97%) chromosomal and 17 (85%) plasmid CDSs predicted to occur in Lb. casei ATCC 334, as well as all predicted CDSs in the draft Lb. helveticus CNRZ 32 genome. CDSs that were not included in the microarray design were all transposase-encoding genes.

Lactobacillus casei is remarkably adaptable to diverse habitats and widely used in the food industry. To reveal the genomic features that contribute to its broad ecological adaptability and examine the evolution of the species, the genome sequence of L. casei ATCC 334 is analyzed and compared with other sequenced lactobacilli. This analysis reveals that ATCC 334 contains a high number of coding sequences involved in carbohydrate utilization and transcriptional regulation, reflecting its requirem ...[more]

Functional redundancy of iron acquisition systems is required for Proteus mirabilis pathogenesis during UTI

Project description:Proteus mirabilis is a primary cause of complicated urinary tract infections (UTI). Surprisingly, iron acquisition systems have been poorly characterized in this uropathogen despite the urinary tract being iron-limited. In this report the transcriptome of strain HI4320, cultured under iron limitation, was examined using microarray analysis. Of genes upregulated at least 2-fold, 45 were statistically significant and comprise 21 putative iron-regulated systems. Two of these systems, PMI0229-0239 and PMI2596-2605, are organized in operons and appear to encode siderophore biosynthesis genes. Five microarrays comparing P. mirabilis HI4320 cultured in LB broth to P. mirabilis cultured in LB broth + 15 uM Desferal (an iron chelator) were analyzed. All five arrays are biological replicates; arrays #2 and 4 are dye swaps.

Project description:Genomic rearrangement, often driven by insertion sequence (IS) elements, is one of the major processes in the evolution of prokaryotes. Sequence analysis of 16S rRNA of Lactobacillus helveticus, an organism that evolved in a dairy environment and Lactobacillus acidiophilus an organism that evolved associated with the gastrointestinal tract (GIT) demonstrated 98.4% identity suggesting that they divergently evolved from a common ancestor. Moreover, complete genome sequence analysis of both organisms has demonstrated a remarkable degree of gene synteny (75% homologous genes) despite the presence of an exceptionally high number and diversity of IS elements in the Lb. helveticus genome. Array based comparative genomic hybridization (aCGH) performed on nine strains of Lb. helveticus revealed sixteen clusters of open reading frames (ORFs) flanked by IS elements. Four of these ORFs are associated with restriction/modification which may have played a role in accelerated evolution of strains in a commercially intensive ecosystem undoubtedly challenged through successive phage attack. Furthermore, analysis of the IS-flanked clusters demonstrated that the most frequently encountered IS were also those most abundant in the genome (IS1201, ISL2, ISLhe1, ISLhe2, ISLhe65 and ISLhe63). These findings contribute to the overall viewpoint on a versatile character of IS elements and the role they may play in bacterial genome plasticity.
