Summary: The study investigated the impact of oxytetracycline and sulfamethoxazole antibiotics, both as single agents and in combination, on the nitrifying microbiome. Results showed that the antibiotic mixture had a more significant and longer-lasting disturbance on nitritation and nitratation compared to the single antibiotic. Bioinformatic analysis revealed changes in the nitrite-oxidizing and ammonium-oxidizing populations, which were associated with the disturbance caused by the antibiotic mixture. Furthermore, the antibiotic mixture also affected the biotransformation pathways of oxytetracycline. Overall, this study provides insights into the environmental consequences of antibiotic mixtures on nitrifying microbiomes.

Summary: The study found that sulfamethoxazole (SMX) can increase methane production by promoting acetogenesis and homo-acetogenesis processes, but inhibits the transformation of butyric acid at certain concentrations. Under anaerobic conditions, acetate kinase and cytochrome P450 enzymes continue to participate in SMX degradation. Based on the products, five biotransformation pathways of SMX were proposed, including hydroxylation, hydrogenation, acetylation, deamination, oxidation, and the elimination of oxygen atoms on the sulfonyl, isoxazole ring, and N-S bond cleavage.

Summary: Antibiotics, when present in aquatic environments at low concentrations, can disrupt the gut microbiome and host gene expression in fish, leading to an imbalance in microbial populations and impaired immune responses. This study found that chronic exposure to low concentrations of erythromycin and ampicillin significantly increased the proportion of opportunistic pathogens, such as Aeromonas veronii, in the fish, while decreasing the proportion of other bacterial phyla. The expression of immune response-related genes, such as chemokines and immunocyte chemotaxis, was also significantly affected in fish exposed to antibiotics in the aquatic environment.
