Abstract
Introduction: Pythiosis is a high-mortality infectious condition in humans and animals. The etiologic agent is Pythium insidiosum. Patients present with an ocular, vascular, cutaneous/subcutaneous, or gastrointestinal infection. Antifungal medication often fails to fight against P. insidiosum. The effective treatment is limited to radical surgery, resulting in organ loss. Fatal outcomes are observed in advanced cases. Pythiosis needs to be studied to discover novel methods for disease control. Genome data of P. insidiosum is publicly available. However, information on P. insidiosum biology and pathogenicity is still limited due to the lack of a cost-effective animal model and molecular tools. Materials and methods: We aimed to develop a high-efficiency protocol for generating P. insidiosum protoplast, and used it to set up an animal model, in vitro drug susceptibility assay, and DNA transformation for this pathogen. Results: P. insidiosum protoplast was successfully generated to establish a feasible pythiosis model in embryonic chicken eggs and an efficient in vitro drug susceptibility assay. DNA transformation is a critical method for gene manipulation necessary for functional genetic studies in pathogens. Attempts to establish a DNA transformation method for P. insidiosum using protoplast were partly successful. Significant work needs to be done for genetically engineering a more robust selection marker to generate stable transformants at increased efficiency. Conclusion: This study is the first to report an efficient P. insidiosum protoplast production for clinical and research applications. Such advances are crucial to speeding up the pathogen's biology and pathogenicity exploration.
