What type of infection is characterized by the presence of bacteria in the blood?

• A. Sepsis
• B. Viremia
• C. Bacteremia
• D. Fungemia

Answer: (C)

The correct response identifies bacteremia as the condition characterized by the presence of bacteria in the bloodstream. Bacteremia refers specifically to the presence of viable bacteria in the blood, which can occur transiently (for instance, after dental work) or can lead to more severe systemic infections, such as sepsis. Understanding this concept is crucial in microbiology because the detection of bacteria in the blood can indicate an underlying infection that requires prompt medical intervention. In certain cases, bacteremia can progress to sepsis, which involves a severe systemic response to the infection. The other options refer to different types of pathogens in the bloodstream. Viremia indicates the presence of viruses in the blood, while fungemia refers to the presence of fungi. Although sepsis implies a serious condition that often results from bacteremia, it encompasses a broader systemic response rather than just the presence of bacteria.
