All rights reserved Introduction into Pathology of Ocular Zoonoses Hans E. Schaefer Institute of Pathology - University of Freiburg im Breisgau Germany Published Zoonosis what does it mean The meaning of the term Zoonosis has changed greatly over the time. At least in the first half of the 19th century early microscopes easily identified fungi small animals protozoans and metazoans bacteria and viruses were much too small to be visualized. Hence for more than a century the term zoonosis indicated any disorder due to infectious agents visible by microscope. Ironically the first reports of cytomegaly were attributed to an infection by a novel fungal or amebic organism. However with the advent of modern microbiolgy the understanding of zoonosis has changed completely. No later than 1958 the World Health Organization produced an official definition of Zoonosis as diseases transmitted in a natural way from vertebrate animals to humans . Currently three subtypes of Zoonoses may be distinguished 1 1. Zooanthroponoses transmitted from vertebrates to humans. 2. Anthropozoonoses rare transmitted from humans to animals. 3. Geonoses Sapronoses diseases produced by animal-borne infectious agents surviving in faeces food soil or on plants from there eventually affecting humans. This treatise on ocular Zoonoses will be divided into two main groups A and B according to their respective way of transmission. A. Zoonoses transmitted through the conjunctiva the eye is the entrance for the infectious agent. A. I. Bacterial agents Parinaud s Syndrome PS PS is probably the first description of an infection by Listeria monocytogenes. It takes its name from the French ophthalmologist Henri Parinaud who in 1889 described a granulomatous conjunctivitis with regional suppurative lymphadenitis and parotid oedema mainly affecting butchers .
