We are still in the process of completing these Disease Descriptions. A number of them do not, as
yet, have their images formatted and some are also lacking the drawings of their Disease Cycles. Please
be patient as we complete these and add a few more examples.
If you have some good photos you'd like to give us copyright to use, we'd certainly be pleased to consider
them.
