Inclusion Conjunctivitis (Encyclopedia of Medicine)
Inclusion conjunctivitis is an inflammation of the conjunctiva (the membrane that lines the eyelids and covers the white part, or sclera, of the eyeball) by Chlamydia trachomatis. Chlamydia is a sexually transmitted organism.
Inclusion conjunctivitis, known as neonatal inclusion conjunctivitis in the newborn and adult inclusion conjunctivitis in the adult, is also called inclusion blennorrhea, chlamydial conjunctivitis, or swimming pool conjunctivitis. This disease affects four of 1,000 (0.4%) live births. Approximately half of the infants born to untreated infected mothers will develop the disease.
Causes and symptoms
Inclusion conjunctivitis in the newborn results from passage through an infected birth canal and develops five to 14 days after birth. Both eyelids and conjunctivae are swollen. There may be a discharge of pus from the eyes.
Most instances of adult inclusion conjunctivitis result from exposure to infected genital secretions. It is transmitted to the eye by fingers and occasionally by the water in swimming pools, poorly chlorinated hot tubs, or by sharing makeup. In adult inclusion conjunctivitis, one eye is usually involved, with a stringy discharge of mucus and pus. There may be little bumps called follicles...

Inclusion Conjunctivitis (Encyclopedia of Children's Health)
Inclusion conjunctivitis is an inflammation of the conjunctiva, or white of the eye. In the neonate this condition is part of a larger group of eye diseases called neonatal conjunctivitis. Inclusion conjunctivitis is also called a chlamydial conjunctivitis.
Chlamydiae are similar to bacteria but cannot produce their own energy and thus live in the cells of other organisms. Once inside the host cell, chlamydiae replicate and form inclusion bodies. They then replace and finally destroy the cell membrane of the host, releasing more chlamydiae to continue the infection process. The life cycle of chlamydia is 72 hours. Chlamydiae are found in parts of the body with a mucosal membrane, which are the eye, the respiratory tract, and the genitourinary tract.
Neonatal inclusion conjunctivitis develops within five to 12 days after birth and is contracted as the child passes through the mother's cervix. Two-thirds of those females with a chlamydial infection pass the infection on to the child during childbirth.
Adult inclusion conjunctivitis, which can affect sexually active adolescents, is usually...
