A compact semi-automated continuous cultivation system for Plasmodium falciparum

Area of Science:

• Parasitology
• Infectious Diseases
• Biotechnology

Background:

• Continuous cultivation of Plasmodium falciparum is crucial for malaria research.
• Existing methods can be labor-intensive and require constant monitoring.

Purpose of the Study:

• To describe a novel, compact, and inexpensive semi-automated continuous cultivation system for Plasmodium falciparum.
• To evaluate the system's ease of use, unattended operation capabilities, and efficiency in achieving high parasitaemia.

Main Methods:

• Development of a semi-automated continuous cultivation system with portable modules.
• Utilizing plastic flasks within modules to achieve a culture surface area of up to 500 cm2.
• Daily medium changes and monitoring of parasitaemia at specific red cell densities.

Main Results:

• The system allows cultures to proceed unattended for several days.
• Portable modules enable easy transfer for manual operations like sampling.
• Routine parasitaemias of 12% are achieved at red cell densities of 1-7 x 10(8)/ml with daily medium changes.

Conclusions:

• The described system is simple to operate and cost-effective.
• It facilitates unattended, long-term cultivation of Plasmodium falciparum.
• The system is suitable for achieving high parasitaemia, supporting malaria research and drug screening.
