Where are endotoxins primarily found?

Endotoxins are primarily located in the cell walls of gram-negative bacteria. These toxins are part of the outer membrane of the bacteria and are released when the bacterial cells die or undergo lysis. Unlike exotoxins, which are secreted proteins produced by both gram-positive and gram-negative bacteria, endotoxins are not actively secreted; they are integral components of the bacteria's structural framework.

Understanding the nature of endotoxins is crucial in microbial remediation as they can trigger strong inflammatory responses in humans and animals. Their presence is a significant concern in environments where bacterial contamination occurs, particularly in water damage and mold remediation scenarios managed by professionals in the field. Recognizing the source of endotoxins is essential for assessing health risks and implementing proper remediation strategies.
