Antimicrobial-resistant enteric bacteria from dairy cattle.
A study was conducted to understand the descriptive and molecular epidemiology of antimicrobial-resistant gram-negative enteric bacteria in the feces of healthy lactating dairy cattle. Gram-negative enteric bacteria resistant to ampicillin, florfenicol, spectinomycin, and tetracycline were isolated from the feces of 35, 8, 5, and 42% of 213 lactating cattle on 74, 39, 9, 26, and 82% of 23 farms...
متن کاملDrosophila host defense: differential induction of antimicrobial peptide genes after infection by various classes of microorganisms.
Insects respond to microbial infection by the rapid and transient expression of several genes encoding potent antimicrobial peptides. Herein we demonstrate that this antimicrobial response of Drosophila is not aspecific but can discriminate between various classes of microorganisms. We first observe that the genes encoding antibacterial and antifungal peptides are differentially expressed after...
متن کاملEnteric Bacteria
Biochemical confirmation of salmonellae by conventional tube methods usually requires 2 to 3 days of incubation time preceded by preparation of tubed media and transfer of cultures. The principles of heavy inocula and increased substrate concentrations have been used by Sanders et al. (1) to speed up reaction times and thus reduce the time necessary in the laboratory for analysis. To characteri...
متن کاملAntimicrobial drug use and antimicrobial resistance in enteric bacteria among cattle from Alberta feedlots.
The purpose of this study was to determine whether antimicrobial resistance (AMR) in foodborne pathogens (Escherichia coli O157, Salmonella, and Campylobacter) and non-type-specific E. coli obtained from fecal samples of feedlot cattle was associated with antimicrobial drug (AMD) use. A secondary objective was to determine if AMR in non-type-specific E. coli could be used as a predictor of AMR ...
متن کاملGlycogen of enteric bacteria.
In the course of an investigation of the use of infrared spectrophotometry for bacterial identification (Stevenson and Bolduan, 1952; Levine et al., 1953b), it has been found that a characteristic set of absorption bands appears in the spectra of Enterobacteriaceae and other bacteria under certain cultural conditions. Since this set of bands is common to many organisms, it is important in ident...
