Hypothesis
The presence of Gnathostoma AdvL3 in fish species frequently eaten by humans in Acapulco suggests these fish may be the main source of infection in recorded cases of gnathostomosis.
Conclusion
The study identifies fish as a potential source of human gnathostomosis in Acapulco, Mexico, highlighting the need for public health awareness.
Supporting Evidence
- Five out of nine fish species examined were positive for Gnathostoma AdvL3.
- E. pictus had the highest prevalence and mean abundance of larvae.
- The presence of the parasite in commonly eaten fish suggests a risk for human infection.
Takeaway
Some fish in a lagoon in Mexico have a parasite that can make people sick if they eat the fish raw or undercooked.
Methodology
Fish were caught and examined for Gnathostoma sp. advanced third-stage larvae using magnifying glass and lamp.
