DRY CLEANING

Pinkeye outbreaks are most frequently seen in summer and autumn when flies are most prevalent and ultraviolet radiation is high... Animals with unpigmented eyelids and protruding eyes are prone to pinkeye, whereas hooded eye conformation, which offers some protection from sunlight and physical damage, may reduce susceptibility to pinkeye... Pinkeye persists in a herd in the eyes of carrier cattle that do not show any signs of the disease. Eye irritation from dust, bright sunlight, thistles and long grass can then cause lachrymation (tear production) which attracts flies. The flies feed on infected secretions and move from animal to animal, spreading the bacteria. Carriers may also carry infection in the nose and vagina, so that discharges fom these areas are also a source of infection.
