[17:41, 06/05/2022] Peter Rogers: To the bird experts out there a question please. A client has an aviary of about 300 seed -eating birds including a wide variety of doves. Over the last few months he has experienced high mortalities amongst the tambourine doves ONLY. A post mortem diagnosis of Chlamydia was made on histopathology and confirmed with PCR I put them onto 3 weeks of Enrovet in the drinking water (started before the results came out) but the mortalities persisted. I then put them onto oxytetracycline also in the water, and still the mortalities have persisted but still only in the tambourine doves. A few weeks after the antibiotics were stopped , another post mortem was done with the same results - HIGHLY positive on PCR for Chlamydia. Interestingly enough, the owner put 6 tambourine doves into a smaller enclosure within the larger aviary right at the beginning of the outbreak - no medication was given and no losses occurred. 🤷♂️ My questions are threefold - why just the tambourine doves, why are the antibiotics not working and why are the untreated ones in the smaller enclosure not affected at all ? As an aside, a few years ago the same Centre experienced severe Chlamydial ocular lesions in their vultures, but again only in the one species (cannot remember which one ) but the other three species were not affected at all . This has smokkeld my brain - please help 🤷♂️ [18:12, 06/05/2022] Henry Labuschagne: Pete. Put them on doxycycline. Make sure correct concentration and all get space to drink. Put visibly sick ones in cage away from rest. Dose 20 to 40 mg q24 hrs . Give a minimum of 200 mg per litre drinking water; also give Protexin. [18:15, 06/05/2022] Nico du Preez : Pete, you can use Doxymax powder. Purchase from any wholesaler. Get in 30g, 100g and 1kg. [18:16, 06/05/2022] Willem Burger: Ockert Botha, Vetscripts [18:17, 06/05/2022] Henry Labuschagne: Get from any pharmacy – take the powder out of capsules ( 100mg per capsule). Dose at 20 to 40 mg per kg. Also be careful when handling birds or working in aviary, as Chlamydia is zoonotic. [18:45, 06/05/2022] David Gerber: V-Tech is making Supadox in 20g sachets which are sold by Afrivet, and Swa-Doxy-Mycin which is sold by Swavet, both are 50% doxycycline water soluble powders. These are both registered stock remedies. As a compound, V-Tech makes liquid doxycycline solution of 25%. [18:59, 06/05/2022] Robert Campbell: David, do you do nystatin for in water as well? [19:05, 06/05/2022] Ockert Botha: It's very important to dose doxycycline in water and in food - some species do not ingest enough water. Nystatin is not water soluble. If there is no improvement, consider long-acting 50mg/ml doxycycline made specifically for birds. Inject 0.1 ml per 100 g every 5 days for 7 consecutive treatments. [19:19, 06/05/2022] Paul: Are there other doves in there too? What species? Exotic or local? Were they breeding now? [22:04, 06/05/2022 Marie-Pierre Ryser: Most likely species specific differences in disease susceptibility, this is observed for many bird diseases in the wild [02:38, 07/05/2022] Elmien Kotze : F10 had a webinar series recently and they did nebulizing of aviaries with F10 solution - apparently works really well for respiratory diseases 09:55, 07/05/2022] Peter Rogers: Thank you for the excellent advice everybody
