The gut microbiota plays important roles in its host. However, how each microbiota member contributes to the behavior of the whole population is not known. In this study, we therefore determined protein expression in the cecal microbiota in chickens of selected ages and in 7-day-old chickens inoculated with different cecal extracts on the day of hatching. Campylobacter, Helicobacter,...

Escherichia coli O111 is an emerging non-O157:H7 serotype of Shiga toxin-producing E. coli (STEC). We previously reported that outbreak and environmental, but not sporadic-case, strains of STEC O111 share a distinct aggregation phenotype (M. E. Diodati, A. H. Bates, M. B. Cooley, S. Walker, R. E. Mandrell, and M. T. Brandl, Foodborne Pathog Dis 12:235–243, 2015, http://dx.doi.org/10.1089/...

Abstract Cold-induced sweetening (CIS), which occurs when potatoes stored at low temperature for long-term, causes changes in flavor and unwanted dark colors in fried and roasted potatoes. The culprit for CIS is an enzyme called invertase. Five potato cultivars A (FD3-10), B (FD3-9), C (TPS-9801), D (393574-61) and E (Laal-e-Faisal) were investigated for invertase activity at cold storage. The...
