3.2.5 Early Detection of Critically Colonized Wounds by
Thermography
Chronic wounds, such as pressure ulcers, are always exposed to external pathogens
and are prone to delayed healing. Conventionally, the relationship between the host
and the bacterium has been thought of as contamination, resident, and infection, but
since about 2000, it has been classified into four categories including critical
colonization. Contamination is a state in which bacteria are present only in the
wound and no growth is observed, and colonization is a state in which bacteria
