Abstract

Routine blood culture is used for the detection of bloodstream infections by aerobic and anaerobic bacteria and by common pathogenic yeasts. A retrospective study was conducted in a public hospital in Maceió-AL, by collecting data of all medical records with positive blood cultures. Out of the 2,107 blood cultures performed, 17% were positive with Staphylococcus coagulase negative (51.14%), followed by Staphylococcus aureus (11.21%) and Klebsiella pneumoniae (6.32%). Gram-positive bacteria predominated among positive blood cultures, highlighting the group of Staphylococcus coagulase-negative. While Gram-negative bacteria had a higher number of species among positive blood cultures.

Highlights

Several people are hospitalized daily and many of them are affected by various diseases
Bloodstream Infections is a serious disease that can quickly lead to death, and without its adequate clinical and laboratory prognosis can hinder an early treatment in the first hours of the disease and in the patient’s survival (Shafer et al, 2019)
The diagnosis of infection is established to an organ or system, being enough to cause an inflammatory process in the individual’s body, which is called Systemic Inflammatory Response Syndrome (SIRS), when the SIRS has an inflammatory cause, it is referred to as a sepsis (Kaukonen et al, 2015)

Summary

Introduction

Several people are hospitalized daily and many of them are affected by various diseases. The identification of bacteria in blood samples determines an important diagnostic resource in infectious diseases. Sepsis was known as septicemias or “blood infection”. Today, it is better known as a generalized infection. It is better known as a generalized infection This definition is not entirely correct because the infection is not necessarily present in all organs. The diagnosis of infection is established to an organ or system, being enough to cause an inflammatory process in the individual’s body, which is called Systemic Inflammatory Response Syndrome (SIRS), when the SIRS has an inflammatory cause, it is referred to as a sepsis (Kaukonen et al, 2015)
