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.

Abstract
Background:Hospital infections worldwide, as a major public health problem, have a significant burden on patients. Therefore, due to the increased antibiotic resistance and mortality in hospitalized patients, this study aimed to determine the frequency of hospital infections and its antibiotic resistance pattern.
Methods:This is a descriptive-analytical study that was conducted on a retrospective survey on 16566 children admitted to the Sheikh Pediatric Hospital in Mashhad. Data were collected using a questionnaire designed for the National Institutes of Internal Medicine Infection Monitoring System (INIS) to detect the prevalence of major hospital infections (blood, urinary, respiratory and burn), and all hospitalized patients were monitored for clinical signs and if they were suspected of being infected, they were confirmed by an infectious expert on the basis of clinical and laboratory symptoms.
Results:In the present study, a total of 16566 patients admitted during the year 1395, 60 cases of hospital infection (0.36%) were observed. The most common type of infection is respectively 0.19%, pneumonia 0.102% , urinary tract infection 0.036% and eye infection 0.030%. The most common bacterial agents in the most commonly reported type of hospital infection in children undergoing infections are Staphylococcus aureus (53.22%). The highest microbial infections caused by Klebsiella are 19.35% and the lowest is Candida Albicans 1.61%.
Conclusion:The results of this study show a lower proportion of hospital infection in this center than the country's statistics one of the reasons for this is the effect of observing handwashing by mothers of children in adolescents and staff, the effectiveness of health education to employees and mothers, as well as the proper use of disposable items. In this study, the highest incidence of infection related to blood infection, 32 cases, due to the fact that patients admitted to hematology and oncology departments are immunocompromised due to their individual circumstances and the nature of the disease ; identifying the causes of these infections and the weaknesses in the care of patients admitted to this section is of great importance.
