In the present study, oxytetracycline and tylosin’s WDTs were estimated. The concentration and depletion of these molecules in eggs were linked to their pharmacokinetic and physicochemical properties. Twenty-seven Leghorn hens were used: 12 treated with oxytetracycline, 12 treated with tylosin, and 3 remained as an untreated control group. After completion of therapies, eggs were collected daily and drug concentrations in egg white and yolk were assessed. The yolk was used as the target tissue to evaluate the WDT; the results were 9 and 3 days for oxytetracycline and tylosin, respectively. In particular, oxytetracycline has a good oral bioavailability, a moderate apparent volume of distribution, a molecular weight of 460 g/mol, and is lightly liposoluble.

  • Lack of Evidence for Direct Linkage of Plant Agriculture Use of Oxytetracycline to Antibiotic Resistance in Human Pathogens
    Lack of evidence for direct linkage of plant agriculture use of oxytetracycline to antibiotic resistance in human pathogens Oxytetracycline: source and mechanisms of resistance. Oxytetracycline (Terramycin) is a naturally produced tetracycline antibiotic of Streptomyces rimosus, with a spectrum of activity similar to chlortetracycline and tetracycline and remarkable thermostability (16). In plant agriculture, oxytetracycline is used in the USA primarily on pear and apple for fire blight management. Oxytetracycline is also important for the management of a serious disease of stone fruits (e.g. peach and nectarine) in the USA called bacterial spot, caused by Xanthomonas arboricola pv. pruni (6,14). Oxytetracycline is bacteriostatic, inhibiting the multiplication of bacterial cells by binding reversibly to the bacterial ribosome blocking the synthesis of proteins (15). As oxytetracycline applied to plant surfaces degrades, the growth of bacteria resumes when oxytetracycline releases naturally from the ribosome (13, 15, 24). Bacteria have three major strategies for developing tolerance to oxytetracycline: efflux pumps, alteration of the ribosome to block binding of oxytetracycline and production of enzymes that inactivate oxytetracycline. Oxytetracycline is not a mutagen, but rather selects for bacterial cells that have developed resistance through acquisition of resistance genes or by accumulation of mutations that occur naturally during replication of its DNA. Over 30 tetracycline resistance genes have been described (5). Plant agriculture-grade antibiotic formulations did not carry resistance genes or 16S rRNA After alarming reports that low-grade avoparcin formulations added to animal feed for growth promotion were highly contaminated with Amycolatopsis orientalis, the producer organism, and its resistance genes for the glycopeptide antibiotic (12, 32), the cleanliness of antibiotic formulations used in plant agriculture was questioned.

Resumen Esta mini-revisión se relaciona con el uso de la oxitetraciclina y la gentamicina, dos antimicrobianos de aplicación en medicina humana, en la horticultura y otras actividades productivas. El manuscrito inicia con una breve descripción del mecanismo de acción y uso clínico de ambas drogas. Seguidamente, el autor aborda los principales mecanismos de resistencia adquirida que han sido descritos hasta la fecha y algunas implicaciones de su mal uso y abuso en escenarios no hospitalarios. En este sentido, se presentan reportes de la ocurrencia de bacterias resistentes y genes de resistencia que demuestran la existencia de un riesgo y que justifican la instauración de programas de monitoreo y de impacto ambiental.
