Louis, Missouri) (each at 25 [micro]g/ml), ampicillin (Sigma), streptomycin (Fisher Scientific, Fair Lawn, New Jersey), gentamycin (Fisher) (each at 10 [micro]g/ml), ciprofloxacin (ICN) (5 [micro]g/ml) or sulfathiazole (ICN) (200 [micro]g/ml).
There was no significant difference between the total number of isolates resistant to sulfathiazole or chloramphenicol over the sampling dates.
All geese carried enterococci resistant to streptomycin and sulfathiazole.
coli resistant to chlorotetracycline and sulfathiazole.
coli was highest to sulfathiazole, the [beta] lactams and to chlorotetracycline.
Sulfathiazole and sulfamethoxypyridazine were commercially pure samples and used as received.
5 mL concentrated hydrochloric acid was poured into a refluxing solution of sulfathiazole (0.
According to experimental data, the structures of the ligands H2L and H2A, prepared by the condensation of benzoylacetone with sulfathiazole or sulfamethoxypyridazine, were listed in Figs.
Six veterinary pharmaceuticals--dimetridazole, metronidazole, thiamphenicol, sulfamethazine, sulfathiazole, and tylosin--were found at median concentrations of 1.
The percentage of samples with positive detections are shown in parentheses for each compound; sulfathiazole and metoprolol were only detected in a single sample each and their respective concentrations were regarded as maximum levels and shown as horizontal bars.
coli isolates from migratory Canada geese sampled on the eastern shore of Maryland in the United States were resistant to penicillin G, ampicillin, cephalothin, and sulfathiazole
