Hypothesis
Does intraspecific competition occur among different strains of Trypanosoma brucei in tsetse flies?
Conclusion
There is a significantly higher proportion of mixed infections than expected in tsetse flies, indicating that the two trypanosome strains do not compete but co-infect.
Supporting Evidence
- 96.4% of infected midguts contained both red and green trypanosome strains.
- Salivary glands with mixed infections had a higher density of trypanosomes than those with a single strain.
- Co-infection rates were similar to those found in single strain infections.
Takeaway
The study found that two types of trypanosomes can live together in tsetse flies without fighting each other, which helps them share genes.
Methodology
Flies were infected with two strains of trypanosomes and their infections were analyzed using fluorescent markers.
Participant Demographics
Experimental tsetse flies from a laboratory colony originally from Zimbabwe.
