Project description:To analyze the gain and lost of genes in Aggregatibacter actinomycetemcomitans during short-term persistent infection in the same host
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. Aggregatibacter actinomycetemcomitans was grown in triplicate in a chemically defined media (CDM) supplemented with either 100uM of ferrous chloride or 50uM of norepinephrine or both. At mid-log, RNA was harvested using the Qiagen Lipid Tissue Minikit.

Project description:To analyze the gain and lost of genes in Aggregatibacter actinomycetemcomitans during short-term persistent infection in the same host The microarray was used to compare gene contents of 4 different pairs of Aggregatibacter actinomycetemcomitans strains (SCC393 vs A160, SCC1398 vs SCC4092, SCC2302 vs AAS4a, and S23A vs I23C), where each pair was isolated from an individual over time. Two biological duplicates were carried out for each strain.
Project description:To characterize the differences in pattern of gene expression between different pairs of Aggregatibacter actinomycetemcomitans strains (SCC393 vs A160, SCC1398 vs SCC4092, and S23A vs I23C), where each pair was isolated from an individual over time.
