xylosus ( Planchon et al., 2009 Xu et al., 2017). Of interest are pathways involved in nitrogen metabolism, amino acids metabolism, and histidine synthesis pathway, all of which has been reported to have a major impact on the biofilm formation of S. It has been shown that metabolism of nutrients has a great influence on biofilm formation ( Planchon et al., 2006). xylosus strains have the ability to form biofilm which could lead to chronic infections and antibiotics resistance ( Parsek and Singh, 2003 Planchon et al., 2006).Д«acterial biofilm formation is a result of several complex molecular mechanisms involving a wide range of proteins that are thought to play major roles in cell adhesion, maturation, signaling, etc. xylosus might be involved in human opportunistic infections and bovine mastitis ( Akhaddar et al., 2010 Rumi et al., 2013 Tan et al., 2014). However, recent studies have demonstrated that S. This AT-rich gram-positive bacteria is normally regarded as non-pathogenic.

Staphylococcus xylosus is a CNS found on the skin of mammals and in food. xylosus, and we propose IGPD as an attractive protein target of cefquinome.

xylosus biofilm formation especially, IGPD involved in histidine metabolism might play a crucial role in sub-MICs cefquinome inhibition of biofilm formation of S. Thus, our data sheds light on important role of histidine metabolism in S.

xylosus by gene ( hisB) knockout, IGPD enzyme activity and histidine content assays. We demonstrated the important role of IGPD in sub-MICs cefquinome inhibiting biofilm formation of S. Interestingly, we found a sharply down-regulated enzyme involved in histidine metabolism pathway in cefquinome-treated cells. Using iTRAQ technique and KEGG database analysis, we found that proteins differently expression in histidine metabolism pathway may play a role in the process by which 1/2-MIC (0.125 Ојg/mL) cefquinome inhibits S. To investigate the potential protein targets of cefquinome, we used iTRAQ for the analyses of cells at two different conditions: 1/2-MIC (0.125 Ојg/mL) cefquinome treatment and no treatment. In our study, we found that sub-MICs of cefquinome were sufficient to inhibit biofilm formation. xylosus biofilm formation and the protein targets of cefquinome. Biofilms are also involved in chronic infections and antibiotic resistance, there are only a few reports about cefquinome inhibiting S. xylosus strains have the ability to form biofilm. It is normally regarded as non-pathogenic, however, recent studies have demonstrated that it is related to human opportunistic infections and bovine mastitis. xylosus) is an AT-rich and coagulase-negative Staphylococcus (CNS).
