A strain of streptomycin-resistant Listeria monocytogenes LM35 isolated from imported frozen beef was examined in this study. In conjugation studies, the L. monocytogenes LM35 strain harbouring two plasmids of 54, 3.0, 2.8 and 2.7 kilobase was used as the donor and streptomycin-sensitive and plasmidless L. monocytogenes LM65 and LM100 strains as the recipients. Streptomycin resistance was trans...
The effects of doxycycline-streptomycin-rifampin versus a standard doxycycline-streptomycin regimen on residual Brucella DNA were compared in 36 acute brucellosis patients. At admission, all patients given triple (n = 22) and double (n = 14) regimens had detectable Brucella DNA with similar mean loads (P = 0.982). At follow-up, 14 to 20 months postpresentation, significantly more patients recei...
Thymidine derivatives of this type are uncommon and only recently have thymidine diphosphate rhamnose I and related deoxysugar nucleotides 17 been described. Guanosine diphosphate mannosO 8 is the only other nucleotide containing mannose. Thymidine diphosphate mannose is of interest as a possible intermediate in the biosynthesis of streptomycin B (a-D-mannopyranosyl-streptomycin) TM, which occu...
Streptomycin is commonly used to control fire blight disease on apple trees. Although the practice has incited controversy, little is known about its nontarget effects in the environment. We investigated the impact of aerial application of streptomycin on nontarget bacterial communities in soil beneath streptomycin-treated and untreated trees in a commercial apple orchard. Soil samples were col...
