Wolbachia presence Yes
Confidence level Medium
Explanation of confidence level

I can’t be completely confident on the fact that I have positive Wolbachia because somehow during the protocol the H2O in the Wolbachia test got contaminated and it showed positive. This lowers my confidence on my bug having Wolbachia.
