Agustina Fitte, 12 Mar 2025 Hi all. I had a case of cysticercosis today on a roan antelope. It was a massive cyst with another one inside. I thought this would be of interest. Dave Midgeley, 16 Mar 2025 Cysticercus? Maybe Hydatidosis? Did the "cyst" have many heads inside. Anna Verster did a lot of work on tapeworm in game species, as did Joop Boomker. I do see "pearls" from time to time and larger cysts in organs, in the abdominal cavity and in the brain. I have not seen one like this though. Interesting indeed. I would like to try and identify it. Did you keep a few heads in formalin or alcohol? Agustina Fitte, 16 March 2025 Hi Dave, thanks for that info. Yes, we kept several samples and have sent it for ID. We plan to write a case report on it. I’ve seen one before on the gluteal muscle of a sable but not a as big as this one. This roan cow comes from the zoo farm in Mokopane, so that can explain it all. Please if you find that discussion would love to go through it. Very interesting case. If you can enlarge the picture, you can have an idea of the size of the cyst. Bossie Boshoff, 16 Mar 2025. Agustina Fitte, [17 Mar 2025]: Very interesting Bossie, it looks exactly the same as the case that I saw. Jacques ODell, [17 Mar 2025 at 06:28:40] Agustina, that is most likely Taenia multiceps or T. serialis. A few other odd Coenuris also possible, but those two are by far the most common causes. Agustina Fitte, [17 Mar 2025 at 10:09:46]: Thanks Jacques! Does somebody have a praziquantel dose for deworming antelope? Roy Bengis, [17 Mar 2025 at 11:02:32]: On game ranches, advise the owner to deworm his dogs (one of the definitive hosts of Taenia multiceps), and to keep them out of the game camps. Agustina Fitte, [17 Mar 2025 at 11:48:25] Thanks Roy, I have other 2 roan in the enclosure, would deworming them be advisable? Jacques ODell, [17 Mar 2025 at 13:52:44]: Agustina, treatment is not always successful but praziquantel and albendazole works okay. As Roy has said, deworm the farm dogs. Agustina Fitte, [17 Mar 2025 at 13:54:34]: Thanks Jacques.
