Not to be too nosy, but what did they culture?
Just in case we run in to this in the future...sometimes you need to know what to ask for

Have you noticed any gut upset from the shots?

Hope they are back to vigorous health soon

He took a swab of his stomach and a dab from his nose.
The results showed aerobic bacterias so I would assume that is what he cultured for. It also showed what meds these were resistive too and which they were sensitive too.

No gut upset from the shots and they have been getting them once a day for two weeks, now I will give it to them once every 48 hours.
I have not noticed any negative effects so far. My vet said he perfers the shots as they do not cause the stomach upset that oral meds do. But Baytril is a painful shot and can cause some distruction to the tissue. So I try not to give it in the same or even near the same location.

The only difference I have noticed is that they are more active and eating more. Ajax is even getting cheeky with poor Echo now. Must be feeling MUCH better.

Thank you for the information...
I am so glad to hear they are eating better and getting cheeky
