In this study, antibiotics and ARGs from the effluent of a veter- inary hospital were measured in order to analyze the efficiency of an alternative wastewater treatment. Based on removal rates of both antibiotics and ARGs, fungal treatment emerges as an inter- esting technology; however, an optimization or combination with other methods is needed in order to reduce the amount of associ- ated microbiota. This treatment offers good results in terms of elimination of certain compounds such as ciprofloxacin, enro- floxacin, marbofloxacin and ampicillin, which are recalcitrant in conventional WWTPs.
It has also been observed that the presence of antibiotic compounds is not the only factor influencing the fate of antibiotic resistance. Therefore, other factors should also be taken into ac- count such as the operational parameters of bioreactors, the wastewater-associated bacterial communities and their interaction with fungi, which may contribute to the spread of resistance genes associated with certain families of microorganisms.
