Long-term clinical, microbiological, and immunological observations of a volunteer repeatedly infected with Chlamydia trachomatis.

A blind volunteer was inoculated in one eye with an isolate of Chlamydia trachomatis in 1961 and followed for 20 years. During this time, many observations were made of his clinical responses to the first inoculation and several subsequent inoculations with the same and other strains, chlamydial shedding, and antibody and cell-mediated immune responses. Evidence is presented that partial resistance to chlamydial eye infection developed during repeated infections and that antibodies, cell-mediated immune reactions, and specific antigen in conjunctival cells persisted for many years after the last infection. The antibody response was directed mainly against the original infecting immunotype, regardless of whether the response was restimulated by infection with the same immunotype or with other immunotypes. The lymphocyte stimulation response appeared to be species specific.

Opportunistic ocular infections.

Since corticosteroids were introduced, a steadily increasing number of opportunistic pathogens have been causing major disease in both systemically and locally compromised hosts. In ocular disease, the most common cause of compromise (and of infection with such opportunistic pathogens as the herpeviruses, many gram-negative bacteria, numerous fungi and Toxoplasma) is the topical use of corticosteroids and antibiotic-corticosteroid preparations. To avoid the damaging and sometimes blinding results of opportunistic infection, the use of these preparations should be carefully restricted.
