Colonization Dynamics of Cefotaxime Resistant Bacteria in Beef Cattle Raised Without Cephalosporin Antibiotics
The emergence of infections caused by antimicrobial resistant microorganisms (ARMs) is currently one of the most important challenges to public health and medicine. Though speculated to originate at least partially from the overuse of antibiotics during food animal production, we hypothesized that cattle are exposed to ARMs in the environment. In this cohort study, a herd of beef calves with no...
متن کاملMicrobial transformations of antibiotics.
In spite of their unusual molecular structures and seemingly high degree of biological recalcitrance, many antibiotics have been shown to be susceptible to microbial attack. Among the types of changes brought about by microbial systems are: (i) acylation; (ii) phosphorylation; (iii) adenylylation and ribonucleotide formation; (iv) hydrolysis; (v) oxidation; (vi) suiph oxidation; (vii) reduction...
متن کاملMicrobial Transformation of Antibiotics: Phosphorylation
Addition of clindamycin to whole-cell cultures of Streptomyces coelicolor MUller resulted in the loss of in vitro activity against organisms sensitive to clindamycin. Incubation of such culture filtrates with alkaline phosphatase generated a biologically active material identified as clindamycin. Fermentation broths containing inactivated clindamycin yielded clindamycin 3-phosphate, the structu...
متن کاملMicrobial Degradation of Sulfonamide Antibiotics
Certain microbes can transform antibiotics in the environment. However, little is known about the identity of these microbes and their antibiotic biotransformation processes. The objectives of this study were to (1) isolate bacterial strains capable of transforming antibiotics, (2) determine the biotransformation kinetics of antibiotics, (3) characterize the effects of background carbons on the...
متن کاملPrevalence of antibiotic-resistant E. coli in retail chicken: comparing conventional, organic, kosher, and raised without antibiotics
Retail poultry products are known sources of antibiotic-resistant Escherichia coli, a major human health concern. Consumers have a range of choices for poultry, including conventional, organic, kosher, and raised without antibiotics (RWA) - designations that are perceived to indicate differences in quality and safety. However, whether these categories vary in the frequency of contamination with...
