Project description:We performed comparative analysis of transcriptomes of S. mutans in single biofilms and in mixed-biofilms with A. actinomycetemcomitans. We also compared the transcriptomic profiles of A. actinomycetemcomitans in single biofilms and A. actinomycetemcomitans in mixed biofilms with S. mutans. Finally we looked at the changes in gene expression in both organisms in time.
Project description:The two-component system qseBC is a putative prokaryotic adrenergic receptor. In Aggregatibacter actinomycetemcomitans (Aa), it was shown that the qseBC responds significantly to the presence of both catecholamines and ferrous iron. In addition, growth is significantly increased in the presence of both. Therefore, we performed a custom Aa microarray in order to determine the effects of catecholamines and catecholamines and iron (CAT-Fe) on Aa.
Project description:To analyze the gain and lost of genes in Aggregatibacter actinomycetemcomitans during short-term persistent infection in the same host
