Environmental Macrolide–Lincosamide–Streptogramin and Tetracycline Resistant Bacteria
Bacteria can become resistant to antibiotics by mutation, transformation, and/or acquisition of new genes which are normally associated with mobile elements (plasmids, transposons, and integrons). Mobile elements are the main driving force in horizontal gene transfer between strains, species, and genera and are responsible for the rapid spread of particular elements throughout a bacterial commu...
متن کاملAntigen specific for bacteria resistant to tetracycline.
Antisera produced against envelope fractions of tetracycline-resistant Escherichia coli and supernatant fluid of disrupted cells of tetracycline-resistant Salmonella typhi were adsorbed with the corresponding fractions of susceptible cultures. With these sera, cross-reacting antigens were demonstrated in the following fractions obtained from tetracycline-resistant strains: envelopes of E. coli,...
متن کاملCharacterization of unusual tetracycline-resistant gram-positive bacteria.
Tetracycline-resistant Tet M-negative isolates of Actinomyces viscosus, Eubacterium lentum, Mobiluncus curtisii, and Mobiluncus mulieris were screened with the Tet K, Tet L, and Tet O DNA probes. Ten (71%) of the resistant Mobiluncus strains hybridized with the Tet O probe, two of the three E. lentum strains hybridized with the Tet K probe, and the A. viscosus isolate hybridized with the Tet L ...
متن کاملAntibiotic-Resistant Enteric Bacteria in Environmental Waters
Sources of antibiotic resistant organisms, including concentrated animal feeding operations (CAFOs), may lead to environmental surface and groundwater contamination with resistant enteric bacteria of public health concern. The objective of this research is to determine whether Salmonella, Escherichia coli, Yersinia enterocolitica, and enterococci resistant to clinically relevant antibiotics are...
متن کاملEffect of tetracycline residues in pig manure slurry on tetracycline-resistant bacteria and resistance gene tet(M) in soil microcosms.
Effects of tetracycline residues from pig manure slurry on the prevalence of tetracycline-resistant bacteria and the tetracycline resistance gene, tet(M), were studied in soil microcosms. Four types of soil microcosms were established for a period of 152 days, supplemented with combinations of pig manure slurry and a tetracycline-resistant Enterococcus faecalis, CG110, containing the tetracycli...
