Pathogenic organisms come in a variety of different forms. Each infection must be carefully evaluated to determine the specific causative organism and the therapy that will be most effective against it. This is usually done through:
1. stool examination.
2. scraping of lesions.
3. incubation of discharge from lesions.
4. culture and sensitivity studies.

The organisms must be carefully cultured and tested to see which medications are effective against them (medication sensitivity).
