Genotoxicity studies (using SOS chromotest and comet assay) of Escherichia coli and carp (Cyprinus carpio) were performed for three pharmaceutically active compounds, ciprofloxacin, 17α-ethinylestradiol and 5-fluorouracil, used in the treatment of humans. The values of genotoxicity induction coefficient (I) in the SOS chromotest clearly showed genotoxicity for ciprofloxacin, both in the presence and in the absence of S9 fraction; 17α-ethinylestradiol demonstrated slight genotoxicity at the highest tested concentration; and 5-fluorouracil did not induce genotoxic effects in Escherichia coli mutants. Statistical analysis of the results of the comet assay revealed significant differences in cell populations derived from carp placed in a solution of 5-fluorouracil in comparison with the negative control. Statistical analysis also showed a significant increase of "% DNA in tail" of comets in cell populations incubated in solutions of 17α-ethinylestradiol at concentrations of 10000, 2000 and 400 µg/L and in solutions of 5-fluorouracil with S9 fraction at concentrations of 50,000 and 2,000 μg/L in comparison with the negative controls.

The World Health Organization has identified multidrug-resistant bacteria as a serious global health threat. Gram-negative bacteria are particularly prone to antibiotic resistance, and their high rate of antibiotic resistance has been suggested to be related to the complex structure of their cell membrane. The outer membrane of Gram-negative bacteria contains lipopolysaccharides that protect the bacteria against threats such as antibiotics, while the inner membrane houses 20-30% of the bacterial cellular proteins.

Despite significant progress in cancer treatment, traditional therapies still face considerable challenges, including poor targeting, severe toxic side effects, and the development of resistance. Recent advances in biotechnology have revealed the potential of bacteria and their derivatives as drug delivery systems for tumor therapy by leveraging their biological properties. Engineered bacteria, including , , and , along with their derivatives─outer membrane vesicles (OMVs), bacterial ghosts (BGs), and bacterial spores (BSPs)─can be loaded with a variety of antitumor agents, enabling precise targeting and sustained drug release within the tumor microenvironment (TME).

The rise in antimicrobial resistance poses a significant threat to global health, particularly among diabetic patients who are prone to urinary tract infections (UTIs). Pathogens that cause UTI among diabetic patients exhibit significant multidrug resistance (MDR) patterns, necessitating more precise empirical treatment strategies..
