Ionophores: their use as ruminant growth promotants and impact on food safety.
Because of the complexity and high degree of specificity of ionophore resistance, it appears that ionophores do not contribute to the development of antibiotic resistance to important human drugs.
What are we doing about Escherichia coli O157:H7 in cattle?
A broad range of live-animal intervention strategies, both probiotic and antipathogen, are described, which could synergistically decrease human illnesses by providing for additional barriers in a multiple-hurdle approach to improving food safety.
Sensitivity of multidrug-resistant Salmonella typhimurium DT104 to organic acids and thermal inactivation in liquid egg products
Differences in thermal sensitivity of the two types of cells were few, and rates of thermal inactivation of S. typhimurium DT104 cells indicate that the USDA pasteurization process would eliminate >8 log 10 cfu ml −1 of EW heated at 57°C and >11 log 10cfu ml -1 of THE AUTHORS, EY, WES, or EYS heated at 61°C.
Effects of short-chain nitrocompounds against Campylobacter jejuni and Campylobacter coli in vitro.
Viable cell counts measured during incubation revealed main effects (P < 0.05) of all nitrocompounds on the survivability of C. jejuni, and the superior inhibitory effect of 2-nitro-l-propanol was reiterated.
Inactivation of Enterobacter sakazakii by water-soluble muscadine seed extracts.
Examining Changes in Soil Organic Carbon with Oat and Rye Cover Crops Using Terrain Covariates
Winter cover crops have the potential to increase soil organic C in the corn (Zea mays L.)-soybean [Glycine max (L.) Merr.] rotation in the upper Midwest. Management effects on soil C, however, are
Mutational analysis of photosystem I polypeptides in Synechocystis sp. PCC 6803. Subunit requirements for reduction of NADP+ mediated by ferredoxin and flavodoxin.
Results suggest that PsaE and the C-terminal domain of PsaD generate the docking site for the electron acceptors of photosystem I, and are more crucial for "docking" of ferredoxin than of flavodoxin.
