Hypothesis
Can a 40-year-old cryopreserved line of Trypanosoma brucei brucei strain 427 be fly transmissible and undergo genetic exchange?
Conclusion
Variant 3, a cryopreserved line of T. b. brucei strain 427, is fly transmissible and capable of genetic exchange.
Supporting Evidence
- Variant 3 was shown to be fly transmissible.
- Variant 3 can undergo genetic exchange with another strain of T. b. brucei.
- Comparison of Variant 3 with lab isolates showed genetic similarities.
Takeaway
Scientists found that an old version of a parasite can be spread by flies and can mix genes with other versions, which is important for studying how these parasites work.
Methodology
The study involved comparing a cryopreserved line of T. b. brucei with lab isolates and conducting genetic crosses through tsetse flies.
Limitations
The study does not address the potential human infectivity of the strains used.
