Although Covid-19 is a viral infection but simultaneous bacterial infection can result in a more severe infection especially in hospitalized patients. This Co-infection can complicate the treatment process and increase mortality in these patients. To date, many studies have been conducted on SARS-CoV-2 infection, but studies regarding the bacterial co-infection of SARS-CoV-2 are scarce.
Three hundred and four blood, sputum, and urine samples were collected from patients with Covid 19 disease who were hospitalized in the intensive care unit of Rasool Akram Hospital for six months. All samples were evaluated with microscopic and biochemical tests. Then they were identified by specific media. The collected data were analyzed by SPSS-26 software.
Out of 304 patients with Covid 19 disease who were admitted to the intensive care unit, 178 (58.6%) were male and 126 (41.4%) were female. 138 patients had a positive culture. The highest prevalence of infection was seen with Klebsiella pneumonia (42) 30.45%, followed by Acinetobacter (30) 21.74% and Staphylococcus aureus (22) 15.95%. The lowest rate of infection was reported with Citrobacter (1) 0.7%.
Our study result showed that Klebsiella pneumonia, Acinetobacter and Staphylococcus aureus are the most common pathogens that cause secondary infections in Covid-19 patients. Although these pathogens may be different in other medical facilities but identification of these agents can be vital in reducing the Covid-19 infection mortality.
