What pathogens cause color breaks?

[Stray59]

Happy Holidays everyone -
Here is a question that I have had for some - just keep forgetting to ask.
Are there any other pathogens, beside virus, that cause color breaks?
Don't some bacterial infections cause such coloration issues? If so, how would you suggest tackling severe bacterial infections? I know of various ways to tackle fungus, but are there any fungal agents that cause either bloom color breaks or form mutation?
Thanks for your input -
Again - Peace and Joy

Beyond viruses, you can have genetics, some chemicals, some pests sucking while the bud is forming…
