Funny you should pose that question. I was just coming back to this thread to ask where I could find some good information on the different strains. I just lost my BA...I don't believe this was Marek's but a poisonous spider bite...and my MJ is limping and staggering this morning. At this point, I am defeated. I don't even know what to do or where to turn anymore. My last thought was to find out the differences and try and find the proper vaccine. Even if I have to go through my vet to do it...I know that he would order it for me. I am so bummed out that I just want to give up. But, if I do, who would take care of my chickens????
I can't agree on all flocks being exposed either. If you have only hatched eggs, or bought hatchery chicks, you would most likely be Marek's free. If you have bought any birds that have been in contact with other people's flocks, you would have a chance that Marek's would be in your flock. If all your chickens are older, and you buy a chicken, you may not have any deaths, and not know that your flock has been exposed.
Most of this information is "most likely" info because nothing is 100% with Marek's. Some die, some do not. There are many different symptoms or no symptoms. Paralysis is not the most common, it's the most common recognised. The paralysis most likely shows up in younger birds. The wasting show up most likely in older birds over a year old. But not all the time.
Since there is no test, we must rely on flock history, patterns of death, and symptoms.
Jessy, I never gave alot of thought to serotypes and virulence, but you have an interesting point, that vaccine does not cover it all. I'm sorry you've been dealing with it too.
Leadwolf, I wonder if it's possible to check into giving several different vaccines to cover more strains, or asking a hatchery what their vaccine is and if it covers more than what is sold to us..
