Results
Wolbachia presence No
Confidence level Medium
Explanation of confidence level

Many people were in the lab (very crowded) pipets and tools might have been contaminated. Although controls are visible, we aren’t 100% certain what the controls are meant to look like. And ladder is very faint so estimating base pairs could be incorrect.
Wolbachia 16S sequence
Arthropod COI sequence
Summary The Arachnida was found to be negative for Wolbachia.
