Wolbachia presence No
Confidence level High
Explanation of confidence level

The arthropod DNA sequences (CO1) showed up for the insect and DNA positive samples, which not showing for the DNA negative control. This indicates that DNA extraction, PCR, and gel electrophoresis were correctly conducted without contamination, validating the procedure used for the Wolbachia 16S sequence electrophoresis. The results are further justified by the DNA positive and Wolbachia positive samples being the only samples to show a band indicating the 16S sequence on the Wolbachia PCR gel, meaning that there was no contamination specifically during the DNA extraction, PCR, and gel electrophoresis protocol concerning the Wolbachia 16S sequence.
