Introduction of Microbes Responsible for Bloodstream Infections
Table of Contents
Bloodstream infections (BSIs) occur when microbes can enter the bloodstream as a severe complication of infections like pneumonia or meningitis, during surgery, or due to catheters and other foreign bodies invading the arteries or veins. Bloodstream infections (BSIs) are associated with significant patient sepsis-related morbidity and mortality across the globe.
List of Microbes Responsible for Bloodstream Infections
A common list of etiological agents of bloodstream infections (BSI) is as follows-
|Type of Microbes||Organisms|
|Coagulase-negative staphylococci (CoNS)|
|Virus||Human Immunodeficiency Virus (HIV)|
|Epstein- Barr Virus|
Keynotes on Microbes Responsible for Bloodstream Infections
- Klebsiella pneumoniae and Escherichia coli are the most common cause of both community and hospital-acquired bloodstream infections (BSIs).
- The frequency of invasive mycoses due to opportunistic fungal pathogens is increasing significantly.
- The patient populations at risk for the development of serious fungal infections are due to solid-organ transplantation, blood, and marrow transplantation (BMT), major surgery, and those with acquired immunodeficiency syndrome (AIDS), neoplastic disease, immunosuppressive therapy, advanced age, and premature birth.
- Blood parasites are organisms that live in the blood of their hosts and they are malaria parasites (Plasmodium species), microfilaria (Wuchereria, Loa loa), trypanosomes, and Babesia.
