[QUOTE="SF, post: 445790, member: 1171"] Opinions do vary on this one Billy. Talk to 10 different researchers and you will get 10 different answers, but I will concede and stand corrected. Here is an interesting thought that I read from one source. "Causes of pinkeye There is controversy among researchers about the cause of pinkeye. Some consider pinkeye to be a syndrome, rather than a specific disease entity caused by the bacterium Moraxella bovis. This is because many different environmental factors as well as a number of different kinds of bacteria, viruses, mycoplasmas and even worm parasites of the eye appear to play a role in herd outbreaks of infectious pinkeye. Tear secretions in cattle appear to be deficient in an enzyme that kills bacteria (lysozyme). Recent work has shown that infected carrier animals may be of major source of infection. A carrier is an animal that may or may not have suffered from pinkeye in the past and may show no outward signs of disease. Nevertheless, in the presence of a number of predisposing factors, this animal is still able to spread the M. bovis bacterium. However, whether it is a virus or a bacteria is irrelevant to the point I was making. It will affect bos taurus cattle primarily in the same manner with little regard to color. Bos indicus cattle seem to be resistent to pink eye in comparison to bos taurus cattle. Greg [/QUOTE]
