    Abstract: From human and animal provenances, antibiotic-resistant microorganisms come into water mediums. Such bacteria are capable of diffusing their genes into water-indigenous microbes, which as well hold resistance genes. Conversely, several antibiotics from industrial sources spread in water mediums, greatly modifying microbial ecosystems. During the la... Show More
