Treatment of these infections is directed at the underlying cause. For proctitis caused by bacterial infection with gonorrhea and chlamydia, the treatment is ceftriaxone and doxycycline. Treatment is usually started before the culture results return from the laboratory and is based on what is seen on examination. The treatments for chlamydia, gonorrhea, herpes, LGV, and syphilis are described in the respective sections in this part of the book.
The treatments for the bacterial causes of enteritis, such as salmonella and shigella and Campylobacter infections, are antibiotics. Giardia infections are usually treated with metronidazole.
Sexual contacts must be examined and treated. For some organisms that cause enteritis, such as giardia and shigella, evaluation of nonsexual household contacts(parents, spouses, children, and siblings) is also recommended, since these infections are fairly easy to transmit nonsexually as well, especially through improper food handling.
