Listeriosis is a rare infectious disease caused by Listeria monocytogenes (L. monocytogenes) in the public. L. monocytogenes is a bacterium that generally infects high-risk patients, particularly the elderly, immunocompromised patients, and pregnant women. Here, we present a case of L. monocytogenes meningitis in a 79-year-old male with diabetes mellitus and pemphigus vulgaris.

Introduction The appropriate use of antibiotics is an important strategy in slowing the development of antimicrobial resistance. This study aimed to evaluate antibiotic consumption and antibiotic use during the coronavirus disease 2019 (COVID-19) pre-pandemic period and pandemic period. Material and methods Antibiotic consumption was evaluated with the antibiotic consumption index (ACI). Results Antibiotics with the largest increase in ACI value during the pandemic period compared to the previous year increased from 0.4 to 1.8 DDI/100 bed days in moxifloxacin. Teicoplanin, linezolid, and clindamycin were not affected in terms of consumption. Conclusions It was observed that the use of many intravenous antibiotics in our hospital increased during the pandemic period.
