As a global transcriptional factor, ArcA regulates the expression of hundreds of genes involved in aerobic and anaerobic metabolism. Here we deleted arcA gene and investigated the biological characteristics of arcA deletion mutant (ΔarcA) in Haemophilus parasuis (H. parasuis) serovar 13 clinical strain EP3. Results indicated that deletion of arcA impaired growth of EP3 strain under anaerobic condition,...
CheY, a response regulator of controlling the bacterial chemotactic swimming, can be modulated by either phosphorylation or acetylation to generate clockwise rotation of the flagella. Here, we researched the biological characteristics of cheY deletion mutant in Haemophilus parasuis, and found that the growth rate of this mutant was significantly slower compared with serovar 13 wild strain EP3. Additionally,...
