Roles of tolC on tolerance to bile salts and biofilm formation in Cronobacter malonaticus.

Xin Wang, Yaping Wang, Na Ling, Yizhong Shen, Danfeng Zhang, Dengyu Liu, Dexin Ou, Qingping Wu, Yingwang Ye,

Bile salts is one of essential components of bile secreted into the intestine to confer antibacterial protection. Cronobacter species are associated with necrotizing enterocolitis in newborns and show a strong tolerance to bile salts. However, little attempt has been made to focus on the molecular basis of the tolerance to ... Read more >>

Role of fliC on biofilm formation, adhesion, and cell motility in Cronobacter malonaticus and regulation of luxS.

Na Ling, Xin Wang, Dengyu Liu, Yizhong Shen, Danfeng Zhang, Dexin Ou, Hongying Fan, Juan Wang, Yu Ding, Jumei Zhang, Qingping Wu, Yingwang Ye,

Cronobacter malonaticus is one of the important foodborne pathogens causing infections mainly in adults. Biofilm formation, adhesion, and motility in Cronobacter have been documented, but the implying molecular mechanism has received little attention. Here, a comparison in biofilm formation, adhesion ability, and cell motility among wild type (WT), △luxS, and ... Read more >>

Random Mutagenesis Applied to Reveal Factors Involved in Oxidative Tolerance and Biofilm Formation in Foodborne Cronobacter malonaticus.

Maofeng Zhang, Xiyan Zhang, Liaowang Tong, Dexin Ou, Yaping Wang, Jumei Zhang, Qingping Wu, Yingwang Ye,

Cronobacter species are linked with life-treating diseases in neonates and show strong tolerances to environmental stress. However, the information about factors involved in oxidative tolerance in Cronobacter remains elusive. Here, factors involved in oxidative tolerance in C. malonaticus were identified using a transposon mutagenesis. Eight mutants were successfully screened based ... Read more >>

Exploration of factors in response to low acid tolerance using random mutagenesis in Cronobacter malonaticus

Liaowang Tong, Dexin Ou, Jumei Zhang, Maofeng Zhang, Qingping Wu, Xiyan Zhang, Yaping Wang, Yingwang Ye,

Cronobacter species are associated with rare but severe infections in newborns, and their tolerance to environmental stress such as acid stress has been described. However, the factors involved in low acid tolerance in Cronobacter are poorly understood. Here, a transposon mutagenesis approach was used to explore the factors involved in ... Read more >>

Inhibitory effects of chitosan on Cronobacter malonaticus cells and biofilm formation

Liaowang Tong, Rui Jiao, Xiyan Zhang, Dexin Ou, Yaping Wang, Jumei Zhang, Qingping Wu, Yingwang Ye,

Cronobacter malonaticus is one of foodborne pathogens associated with life-threating infections in newborns and adults. Controlling C. malonaticus in food samples is important to achieve microbial safety. In this study, inhibitory effects of chitosan with low molecular weight (LMW) and high molecular weight (HMW) on growth of C. malonaticus cells ... Read more >>

Genes involved in tolerance to osmotic stress by random mutagenesis in Cronobacter malonaticus.

Maofeng Zhang, Xiyan Zhang, Liaowang Tong, Yaping Wang, Dexin Ou, Jumei Zhang, Qingping Wu, Yingwang Ye,

Cronobacter malonaticus is one of the opportunistic food-borne pathogens in powdered infant formula and has unusual abilities to survive under environmental stresses such as osmotic conditions. However, the genes involved in osmotic stress have received little attention in C. malonaticus. Here, genes involved in osmotic stress were determined in C. ... Read more >>

Short communication: Roles of outer membrane protein W (OmpW) on survival and biofilm formation of Cronobacter sakazakii under neomycin sulfate stress.

Yingwang Ye, Na Ling, Jina Gao, Maofeng Zhang, Xiyan Zhang, Liaowang Tong, Dexin Ou, Yaping Wang, Jumei Zhang, Qingping Wu,

Cronobacter sakazakii is associated with severe infections including sepsis, neonatal meningitis, and necrotizing enterocolitis. Antibiotic resistance in Cronobacter species has been documented in recent years, but the genes involved in resistance in Cronobacter strains are poorly understood. In this study, we determined the role of outer membrane protein W (OmpW) ... Read more >>
