Objective:
This study aimed to detect the presence of Wolbachia and Spiroplasma endosymbionts in Musca flies through molecular approaches.
Methods:
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.
Results:
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).
Conclusion:
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.
Insights
This study found no Wolbachia endosymbionts in Musca flies but detected Spiroplasma in 5% of females. This is the first report of Spiroplasma in Musca flies.
Area of Science:
- Microbiology
- Entomology
- Molecular Biology
Background:
- Endosymbiotic bacteria play crucial roles in insect physiology and reproduction.
- Wolbachia and Spiroplasma are common endosymbionts with significant impacts on their hosts.
- Musca flies are globally distributed and economically important insects.
Purpose of the Study:
- To investigate the presence of Wolbachia and Spiroplasma endosymbionts in Musca flies.
- To utilize molecular techniques for accurate detection of these bacteria.
- To establish a baseline for endosymbiont prevalence in Musca populations.
Main Methods:
- Collection and dissection of 40 Musca spp. specimens (20 female, 20 male).
- DNA extraction followed by standard polymerase chain reaction (PCR) using specific primers.
- Targeted PCR assays for Wolbachia (wsp, GroEL genes) and Spiroplasma (16S rRNA gene).
Main Results:
- Wolbachia endosymbionts were not detected in any of the Musca fly specimens.
- Spiroplasma was detected in one female Musca fly (5% prevalence).
- No Spiroplasma was found in male Musca flies.
Conclusions:
- Wolbachia appears to be absent or present at undetectable levels in the studied Musca population.
- Spiroplasma endosymbionts can infect Musca flies, with a higher prevalence observed in females.
- This study provides the first molecular evidence of Spiroplasma detection in Musca flies, opening avenues for further research.
