TL;DR: No evidence is found that dietary inclusion of monensin or tylosin, alone or in combination, increased fecal shedding of E. coli O157:H7 or its persistence in the environment.

TL;DR: Sixty individually housed Charolais crossbred steers originating from one ranch source had a 12-d adaptation period in their pens to adjust to their ration and surroundings, followed by two consecutive backgrounding periods with overall prevalence of C. andersoni and G. duodenalis 85 and 82%, respectively.

TL;DR: The environmental conditions that may promote STEC biofilm formation in food processing facilities are identified and the ability of specific strains to form biofilms contributes to their persistence within these environments.

TL;DR: Dry matter intake and average daily gain of steers increased and feed efficiency improved linearly with increasing grain level in the isonitrogenous diets of alfalfa or fenugreek silage, supplemented with three levels of steam-rolled barley.

TL;DR: The results suggest that Bgxa1 has a number of properties that make it an interesting candidate for the saccharification of lignocellulosic material and the deletion of the PA14 domain and insertions in loops adjacent to the active site are found to be an important determinant in the substrate specificity of proteins related to B gxa1.
