Wall teichoic acid structure governs horizontal gene transfer between major bacterial pathogens
Mobile genetic elements (MGEs) encoding virulence and resistance genes are widespread in bacterial pathogens, but it has remained unclear how they occasionally jump to new host species. Staphylococcus aureus clones exchange MGEs such as S. aureus pathogenicity islands (SaPIs) with high frequency via helper phages. Here we report that the S. aureus ST395 lineage is refractory to horizontal gene ...
متن کاملPossible inhibitory effect of teichoic acid on Bacillus subtilis transfer ribonucleic acid.
1. tRNA of Bacillus subtilis was found to be variably contaminated with membrane teichoic acid. 2. Samples with high contents of teichoic acid showed no accepting activity for tRNA(Phe) and tRNA(Tyr). 3. Removal of teichoic acid restored accepting activity and fractions containing teichoic acid, separated on Sephadex G-150, inhibited the charging of tRNA(Tyr). 4. The presence of teichoic acid d...
متن کاملChanges in wall teichoic acid during the rod-sphere transition of Bacillus subtilis 168.
Wall teichoic acid (WTA) is essential for the growth of Bacillus subtilis 168. To clarify the function of this polymer, the WTAs of strains 168, 104 rodB1, and 113 tagF1 (rodC1) grown at 32 and 42 degrees C were characterized. At the restrictive temperature, the rodB1 and tagF1 (rodC1) mutants undergo a rod-to-sphere transition that is correlated with changes in the WTA content of the cell wall...
متن کاملCell wall teichoic acid as a reserve phosphate source in Bacillus subtilis.
Although exponential growth of Bacillus subtilis 168 in a phosphate-limited medium halted with the exhaustion of inorganic phosphate, the bacteria continued to grow at a slower rate for a further 3 to 4 h at 37 degrees C. This postexponential growth in the absence of an exogenous phosphate supply was accompanied by a loss of teichoic acid from the cell walls of the bacteria. Quantitative analys...
متن کاملInvestigating Gram-positive Wall Teichoic Acid Investigating the Dispensability of Wall Teichoic Acid in the Gram-positive Bacteria Bacillus Subtilis and Staphylococcus Aureus
In recent decades, the emergence of multi-drug resistant pathogenic organisms has proven to be a significant threat to human health. Today, resistant organisms have been identified for every class of antibiotics introduced into clinical practice. Combining this with the knowledge that the introduction of new antimicrobial classes has been almost non-existent since the early 1960's, stresses the...
