Area of Science:

  • Microbiology
  • Cell Biology
  • Parasitology

Background:

  • Wolbachia are essential bacterial symbionts found in many arthropods.
  • Maintaining Wolbachia viability outside of host cells is crucial for research applications.

Purpose of the Study:

  • To provide a detailed video protocol for the purification and maintenance of extracellular Wolbachia.
  • To demonstrate methods for assessing Wolbachia viability and suitability for downstream applications.

Main Methods:

  • Purification of Wolbachia from cultured mosquito cells.
  • Fluorescent viability assay for extracellular Wolbachia.
  • Maintenance of purified Wolbachia in cell-free medium.

Main Results:

  • Purified Wolbachia remain viable in cell-free medium for at least one week at room temperature.
  • Extracellular Wolbachia do not replicate until re-inoculated into eukaryotic cells.
  • Purified Wolbachia are suitable for micro-injection and DNA extraction.

Conclusions:

  • This protocol enables the successful isolation and short-term preservation of viable extracellular Wolbachia.
  • The method facilitates the use of Wolbachia in various experimental procedures, advancing research in host-symbiont interactions.
