Prevalence of Gram-Negative Bacteria Among Patients Admitted to Shahid Rajaee Hospital of Karaj in 1396

Abstract

Introduction: Septicemia or blood infection is one of the most important causes of mortality in patients hospitalized in different parts of hospitals, which is considered as an emergency medical emergency. This study was conducted to investigate the role of Gram-negative bacteria in the development of blood infection in Rokhayee hospital in Karaj. Materials and Methods: This study was performed on 3500 patients with septicemia suspicious symptoms admitted to Shahid Rajaee Hospital. Samples were taken from patients for blood culture. The bacteria developed in blood cultures were isolated and identified using conventional bacteriological methods. Results: Out of 3500 patients under study during one year, 70 cases of Gram-negative bacteria were isolated in blood cultures, 13 of which were in the first six months of the year and 57 of them were in the second six months. In total, six types of Gram-negative bacteria were isolated from patients (Escherichia coli, Enterobacter, Pseudomonas, Acinetobacter, Yersinia, and Klebsiella). Escherichia coli was the most common bacteria responsible for the infection of the blood. Conclusion: The results of this study showed that Gram-negative bacteria were the main causes of blood infection and mortality and the prevalence of blood infections in the second month was higher.
