The medicinal resistance of salmonellae isolated in the USSR and the Slovak Republic in 1987-1988 was studied. The resistance of salmonellae at this period was shown to decrease in comparison with the period of 1985-1986. The study revealed the presence of multiresistant strains capable of the conjugative transmission of some resistance markers. The minimal inhibiting concentrations of antibiotics to which salmonellae proved to be resistant were determined.

Objective: Bacterial gastroenteritis is a significant public health concern, capable of causing severe infections. Among the various pathogens involved, those belonging to the Enterobacteriaceae family are the most frequently isolated and associated with gastrointestinal disorders. This study aimed to investigate the prevalence of common diarrheagenic Enterobacteriaceae in Iran over the past two decades, from 2000 to 2023.

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).
