Possibly Dealing with Corid Resistant Cocci.......Thoughts?

[mymilliefleur]

Hello All, I believe I may be dealing with a nasty strain of Corid resistant Cocci.

The end of April I purchased a Mille Fleur d'Uccle rooster and added him to a flock of 9 MFd'U hens, ranging in age from 2-9 yrs. Right away I noticed the roo had diarrhea and was a little thin, but I thought he just needed a little TLC and STUPIDLY left him with the flock. He seemed to improve at first, but 4 days after adding him, several of the hens also had come down with severe lithargy and diarrhea. NO Blood.

Over the course of about 6 days 5/9 of the hens passed, all about 48 hrs after symtoms started, then the roo also passed. Of the remaining 4 hens, 2 never had noticeable symtoms, and 2 were sick but recovered. I put them on Corid right away suspecting Cocci, but it seemed to have little affect.

I sent one of the dead hens to my state lab for testing. The verdict just came back: Coccidiosis with a secondary bacterial infection. I believe it must be a Corid ressistant strain.

Now it appears one of the hens who recovered is acting a little lithargic.

My research tells me I need a heftier drug, such as a type of Sulfa medication. The problem is, they all require prescription, which I'm not going to be able to get (the vets in my area will not even see a chicken). So are there other over the counter drugs you would recommend? What about Toltrazuril?

And what about this product, it looks like I can get it without a presciption: https://birdpalproducts.com/product...JTFqu344ZNlp_BdSxl5amP16QRfIBndA67bIuCFZyKMge

Thank you so much!

I would definitely try the trisulfa!

Try ordering here. https://jedds.com/products/trimethoprin-sulfa-medpet?_pos=1&_sid=9ba243557&_ss=r It has a coccidiostat plus a sulfa antibiotic. No prescription needed.

The way Corid works is to block thiamine from being absorbed by the chicken's intestines. This deprives coccidia of food and they starve. Corid isn't an antibiotic so it won't treat secondary bacterial infection.

Even though there may not be blood in the stools, infection can occur. What happens is the coccidia erode the intestinal lining and the resulting inflammation can grow bacteria. This is what kills the chicken.

Thanks for the info! From what I'm reading, it seems like there are quite a few strains that are resistant to Corid.

Yes, it's a concerning problem. Here's what turned up when I researched advice on the issue.

What can be done about resistance?

• Drug Rotation: Utilizing different anticoccidial drugs with varying mechanisms of action in a rotating schedule (shuttle programs) can help slow down the development of resistance.
• Good Management Practices: Implementing sound hygiene and management practices, such as proper sanitation, reducing stress, and optimizing feeding and housing conditions, can minimize the need for medication and help prevent resistance.
• Natural Alternatives: Research is exploring natural alternatives like phytomolecules (derived from plants) which can potentially complement or even replace chemical anticoccidials in some cases, offering a broader approach to control coccidiosis.

That's what I use. Sorry for your losses.

Good info. I wonder about all the use of medicated feed, and if that's helping to create resistance. I've never fed medicated to my chicks because of that concern.

Thank you Cathy! The other hen I was worried about seems to have recovered today, but I'm going to go ahead and order some meds to have on hand. Do you think the 4 surviving hens will be carriers? I still have them quarantined, and the ground they were on while infected fenced off.
