Now I have a possible explanation of my neverending overgowth:
"C. albicans can prevent the regrowth of Lactobacillus spp. in the stomach after cefoperazone and promote increased colonization by Enterococcus spp"
After 3 rounds of Antibiotics for ENT infections they found these bacteria in my mouth!
I was thinking about candida and they told its just another bug but now make sense. discovered candida overgrowth later with stool test
