                                                         a pig with Erysipelothrix insidiosa sp. (now E. rhu-
                                                         siopathiae) infection. This pig was treated with
                                                         antibiotics and subsequently recovered.

                                                         of deaths at lambing time but the presence of the
                                                         occasional deformed lamb may not necessarily indi-
                                                         cate that there is a disease present. Abnormalities
                                                         like this one-eyed lamb (‘cyclops’) occur during
                                                         development, abnormal embryos are usually reab-
                                                         sorbed or aborted early in development. Occasionally
                                                         some survive to term but die shortly after birth. This
                                                         lamb was one of two, the other lamb was normal.
                                                         Some mycotoxins, plants or drugs may result in
                                                         foetal abnormality (that is, they are teratogenic).
