“…Exogenous pollutants such as antibiotics can induce oxidative stress in organisms, which plays a crucial role in the study of antibiotic toxicity [47]. In earthworms exposed to oxytetracycline in the present study, tissue biomarkers were significantly affected.…”

“…As the second line of defense of the antioxidant system, when oxidative damage in the earthworm body increases, "detoxification" is initiated [79,80] to promote the reduction of toxic peroxides into non-toxic hydroxyl compounds and to promote the decomposition of H 2 O 2 in the earthworm body [81,82]. Detoxifying enzymes may affect the diversity of microorganisms in earthworms [47]. When GST increases, the utilization intensity of microorganisms in earthworms to polymer carbon sources increases, and the microbial population mostly comprises microorganisms that use polymer carbon sources.…”

Antibiotic contamination has become a global environmental issue of widespread concern, among which oxytetracycline contamination is very severe. In this study, earthworm (Eisenia fetida) was exposed to oxytetracycline to study its impact on the soil environment. The total protein (TP), catalase (CAT), superoxide dismutase (SOD), peroxidase (POD), malondialdehyde (MDA), glutathione S-transferase (GST), and glutathione peroxidase (GPX) oxidative stress indicators in earthworms were measured, and the integrated biomarker response (IBR) approach was used to evaluate the toxic effect of oxytetracycline on earthworms. A Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) and a path analysis model were used to explore the physiological and metabolic processes of earthworms after stress occurs. The results showed that SOD, GPX, and GST play important roles in resisting oxytetracycline stress. In addition, stress injury showed a good dose–effect relationship, and long-term stress from pollutants resulted in the most serious damage to the head tissue of earthworms. These results provide a theoretical basis for understanding the toxic effect of oxytetracycline on soil animals, monitoring the pollution status of oxytetracycline in soil, and conducting ecological security risk assessment.
