Bacterial Distribution and Susceptibility in Bloodstream Infection in Primary-Care Hospital in Nova Friburgo, Rio de Janeiro
Abstract Human blood is sterile. When there is an infection, microorganisms can reach the bloodstream, which is known as bacteremia. This can be detected by blood culture. To study the prevalence of microorganisms isolated from blood culture samples. One hundred thirty-seven blood cultures were collected from hospitalized patients. All blood samples were processed for culture using a BACT/Alert blood culture machine. Further identification of bacterial pathogens and their antimicrobial susceptibility test were performed using standard microbiological procedures.Among these samples, 20.44% had a positive culture, 60.71% of which belonged to females and 39.29% were from male patients. The most common microorganisms found in positive blood cultures were coagulase negative Staphylococcus (33.33%), Staphylococcus aureus (23.33%), Klebsiella pneumoniae (6.70%), and Escherichia coli (6.66%). One sample showed an ESBL-producing E. coli. Gram-positive microorganisms were 100% susceptible to vancomycin and displayed considerable resistance to oxacillin. Many Gram-negative bacteria were resistant to cephalosporins..
