Resistance to oxytetracycline, oxolinic acid and furazolidone in bacteria from marine sediments

Sediments experimentally treated with oxytetracycline (OTC) or oxolinic acid (OXA) were placed on the seabottom for a period of 1 year. At the end of the test period the fraction of bacteria resistant to OTC in sediments to which OTC had been added (SOT) was more than three times higher (16%) than t...

Zusammenfassung:Sediments experimentally treated with oxytetracycline (OTC) or oxolinic acid (OXA) were placed on the seabottom for a period of 1 year. At the end of the test period the fraction of bacteria resistant to OTC in sediments to which OTC had been added (SOT) was more than three times higher (16%) than the background level (5%). The same tendency was found for the sediments to which OXA was added (SOX). Cross-resistance towards OTC and OXA was found both in SOT and SOX. A high level of cross-resistance (34%) towards furazolidone was found for SOX, but was not observed for SOT.
