The first link in the chain of infection is the pathogen. A pathogen is anything that causes a disease. Bacterium A group of microscopic organisms that are capable of reproducing on their own, causing human disease by direct invasion of body tissues. Bacteria often produce toxins that poison the cells they have invaded.
In anaerobic clostridial infections, these enzymes play a role in invasion and pathology. Most of the clostridia are saprophytes, but a few are pathogenic for humans, primarily Clostridium perfringens, C. difficile, C. tetani and C. botulinum. Those that are pathogens have primarily a saprophytic existence in nature and, in a sense, are opportunistic pathogens.
