Strangles - Time lapse with symptoms?

Hi All, just wondering if anyone has had a similar experience with Strangles: Back in November my riding horse became ill with a cough, temperature and generally under the weather. The vet diagnosed aspiration pneumonia after two visits and it wasn't until a third visit, after other ponies became ill with more classic Strangles symptoms that Strangles was confirmed. Unfortunately, the delay in diagnosis meant that the original horse had had access to all my others and no bio security measures had been put in place because of the pnuemonia diagnosis. Anyway, it basically went through my whole herd of Shetlands and the last pony became symptomatic at the end of December and was symptom free by 7th January. We haven't seen any symptoms in any ponies since then. At the time we decided to cancel all sales until Easter to be safe (vet advised 6 weeks) so nothing has been on or off the yard since the initial diagnosis. One of the ponies that was heavily symptomatic from 15th December for around 7 or 8 days was a 3yo homebred gelding. He had a really snotty nose, loss of condition, slight cough and was really miserable, but no abscesses. Once he was better he has been fine ever since, but yesterday an abscess burst under his jaw - 4 months on from his initial infection! He is absolutely fine in himself, just has this abscess which was quite gooey yesterday. The vets have just advised to give Bute if needed, and re-isolate for 6 weeks, but I am curious as to why there could be a time lapse between symptoms? Anybody experienced similar?

No real insight to give but given that as mammals we all have different immune systems and how we react to the same virus is therefore different..it may have had a longer “brewing” time. As a horse owner your experience is slightly concerning as it would mean we must be on our guard for longer if the the strangles virus is diagnosed on our yards..so thank you for bringing it to my attention.

Thanks for your reply, my thoughts were the same as yours - vet said 6 week isolation, I gave 3 months to be absolutely sure and then still end up with a potentially infectious case - he was due to go to his new home today so it's fortunate that the abscess came to light before he had the chance to mix with new ponies ( although the only new addition to our farm since the original infection is my daughter's new riding pony, who my sister kept at her's until we were well out of our isolation period. Typically she was in the same field as him when all this happened :/ ) He is his usual chirpy self this morning, no other symptoms whatsoever - just lots of goo draining out!

It can sit in the guttural pouches for ages - that's why vets should recommend a scope and wash. Horses can go on to be carriers without showing any symptoms.

We had to have clear blood tests & / or clear pouch wash before the all clear was given.
