Not sure where I posted 2 other research studies on recent research regarding Marek's treatments. They were all about Chinese substances: Glycyrrhiza uralensis (not glabra which might caught hemorrhages) to shrink tumors, also Dan Shen to stop new tumors from forming, both from one study that tested about 20 traditional Chinese medicine substances. The other study used Baicalin from scuttelaria baicalensis Georgi.
Finally found my last post:
Marek's Disease
I'm in a hurry tonight but here's another one. I usually have to use Google to find research but got lucky with Bing this time.
Anti-herpes virus activity of soursop ( Annona... | Posters | F1000Research
So looks like I'm ordering L-lysine as well as more cranberry extract for the pullets I'm treating now. Turns out Soursop is a no go. After I read more about Soursop, I found it has some serious neurological side effects, the last thing Marek's victims need.
I know I'm changing too many variables at once to know which substance(s) worked if any do, but I'm slightly encouraged that the one who won't eat fought so hard against crop feeding today after only 3 days of Chinese licorice root powder and cranberry extract in her formula and water. Slightly encouraged because previous victims all had good days before downturns.
Found new research for Lysine as a treatment for Covid-19:
(PDF) Lysine Therapy for SARS-CoV-2 (researchgate.net)
I read the whole thing because I was worried about side affects. Lysine has warnings too, mainly to prevent the virus from using Arginine to multiply. For Covid-19 victims, coffee/caffeine are big no-nos. As bad as the pandemic is, I hoped the research would somehow benefit chickens with Marek's.
Hope this helps somebody, if not their chickens.
