Wolbachia spp. and Spiroplasma spp. in Musca spp.: Detection Using Molecular Approaches

Abstract

This study aimed to detect the presence of Wolbachia and Spiroplasma endosymbionts in Musca flies through molecular approaches. In total, 40 Musca spp. (20 female and 20 male) were used. Before DNA extraction, the flies were dissected and their heads, wings and legs were detached from their bodies under a stereomicroscope. Genomic DNA was analysed by standard polymerase chain reaction (PCR) using primers against Musca beta-tubulin. Afterward, the samples were examined for the presence of Wolbachia spp. using primers against Wolbachia wsp and GroEL. Furthermore, the DNA samples were analysed by PCR to detect the presence of Spiroplasma using primers against the 16S rRNA. No Wolbachia positivity was detected in Musca flies, as shown by the negative PCR results for wsp and GroEL. Spiroplasma positivity was detected in 5% (1/20) of the female Musca flies but not in the male flies (0/20). Wolbachia spp. were not detected in Musca flies. Of the total Musca flies, only one was positive for Spiroplasma spp. To our knowledge, this is the first study to detect the presence of Spiroplasma in Musca flies.
