Ceftazidime/Avibactam and Other Commonly Used Antibiotics Activity Against Enterobacterales and Isolated in Poland in 2015-2019.

Purpose: Infections caused by resistant Gram-negative bacteria are becoming increasingly common and now pose a serious public health threat worldwide, because they are difficult to treat due to few treatment options and they are associated with high morbidity and mortality. The combination of ceftazidime with the beta-lactamase inhibitor avibactam - seems to be the right choice in this situation. The aim of the study was to evaluate the activity of ceftazidime/avibactam and other commonly used antibiotics against Enterobacterales and strains isolated within last years in Poland.
