Acinetobacter spp. are bacteria responsible for hospital infections, especially among patients submitted to medical devices like mechanical ventilation and catheters. Severe-ill patients with COVID-19 require hospital care, often in Intensive Care Units. These patients are vulnerable to nosocomial or secondary infections as a consequence of immune system imbalance as a consequence of the acute infection by the SARS-CoV-2. This manuscript aims to analyse the current scientific literature on the impact of infection by species of the genus Acinetobacter concomitant to COVID-19 severe-ill patients. Carbapenem-resistant strains of Acinetobacter spp. are prevalent almost worldwide, and strains with resistance to Polymyxin, Colistin and other antibiotics emerge as new threats to critically-ill COVID-19 patients. The context of the SARS-CoV-2 pandemic, particularly the use of empirical antibiotic therapy, may contribute to the selection of opportunistic pathogens and promote an increase of multidrug-resistance profiles, leaving as a legacy the proliferation of populations of Acinetobacter spp. hard to control in the hospital environment for the near future.
Keywords: COVID-19, SARS-CoV-2, Acinetobacter spp., Secondary infections, Multidrug-resistant pathogens.
