The antibacterial activity in vitro of Imipenem (N-formimidoyl-thienamycin) was studied on 237 recently-isolated nosocomial bacterial strains and compared with Aztreonam, Cefotaxime, Ceftazidime, Ceftriaxone, Piperacillin, Amikacin and Netilmicin through the determination of susceptibility by the Kirby-Bauer method. Taking into account that 65% bacterial strains, out of the examined ones, came from antibiotic high-pressure departments (45% from bone-marrow transplanted patients in the Hematological Department and 20% from Intensive Care Unit patients), the results obtained in vitro show an activity of Imipenem on Gram-negative bacteria as much as a 92.7% susceptibility and a 75.7% on Gram-positive bacteria; when compared with the activity of the other antibiotics, Imipenem shows a really excellent activity.

Catabolic plasmids are critical factors in the degradation of recalcitrant xenobiotics, such as dioxins. Understanding the persistence and evolution of native catabolic plasmids is pivotal for controlling their function in microbial remediation. Here, we track the fitness and evolution of Rhodococcus sp.

Objective: Antiresorptives cases of adverse reactions to highly effective drugs used to treat skeletal-related events that occur during treatment of osteoporosis or malignancy have been reported in the jaw. To date, there is no clear pathophysiology for medication-related osteonecrosis of the jaw (MRONJ), but the role of inflammation or infection has been proposed as one of several possible pathogenesis theories. This study was designed to investigate the role of infection in the pathogenesis of MRONJ by analyzing the microbial communities observed in the bone samples from MRONJ patients.

Inducer-free expression systems are promising tools for biorefinery because they can reduce the reliance on inducers, reducing production costs and simplifying processes. Owing to their broad range of substrate structures and catalytic reactions, cytochrome P450s are promising biocatalysts to produce value-added compounds. However, unsuitable levels of cytochrome P450 expression could result in cell stress, affecting the efficiency of the biocatalyst.

This study investigated the effects of non-thermal atmospheric plasma (NTAP) treatment on the growth, chemical composition, and biological activity of geranium (Pelargonium graveolens L'Herit) leaves. NTAP was applied at a frequency of 13.56 MHz, exposure time of 15 s, discharge temperature of 25 °C, and power levels (T1 = 50, T2 = 80, and T3 = 120 W).
