| antimicrobial substances produced by staphylococcus aureus strains isolated from cattle in brazil. | among 46 isolates of staphylococcus aureus obtained from cattle in the state of paraíba, brazil, four were shown to produce antimicrobial substances (ams). the two best ams producers carried single plasmids of about 8.0 kbp and 50 kbp, respectively, which were designated prj34 and prj35. curing experiments and molecular analysis associated the ams production with the presence of these plasmids in the cells. the biochemical properties exhibited by the ams suggested that they might be bacteriocins ... | 1998 | 9812401 |
| antimicrobial drug resistance in staphylococcus aureus isolated from cattle in brazil. | isolates of staphylococcus aureus obtained from apparently healthy cattle in the state of paraiba, brazil were characterized in relation to resistance to 21 antimicrobial agents. among the 46 isolates obtained, resistance to penicillin was most frequent, followed by resistance to cadmium, streptomycin, arsenate, tetracycline, mercury, erythromycin and kanamycin/neomycin. all isolates were susceptible to fusidic acid, ethidium bromide, cetrimide, chloramphenicol, benzalkonium chloride, doxycyclin ... | 1995 | 7786507 |
