the first photo is candida which is a result of having parasites in the first place. parasites put a burden on your immune system and also excrete waste into the blood causing candida. your bodys immune system is fighting parasites allowing the candida to profilerate as a secondary infection. the second pic looks like roudworms nematode casings. its also a possiblity you have actual worms in that particular bowel movement as well. you have to remove some of the debris from the toilet and wash them. you might want to freeze unfamilar debris in case you have a stool test from your doctor in the future.
