House Finch Conjunctivitis
(Mycoplasma gallisepticum)

This photograph, taken in late winter 1994, is perhaps one of the first ever taken of the finch conjunctivitis outbreak, caused by the organism Mycoplasma gallisepticum. It was among a roll of photos that were forwarded to the federal National Wildlife Health Center in Madison, WI, alerting them to the existence of this new disease perhaps for the first time. Though difficult to tell from this digitized image, there are at least five house finches infected with the disease in this photo. Photo by the Author.
