RESUMO
A laboratory-based study was performed in order to assess the infestation capacity of the mosquito parasite nematode Romanomermis iyengari Welch, on Anopheles nuneztovari Gabaldón and Aedes aegypti L. For each mosquito species, nine hundred (900) I to III instars larvae were taken. These larvae were infested with pre-parasitic larvae of R. iyengari in proportions of 5:1 and 10:1. The infestation averages obtained were 3.9 and 6.7 for Anopheles nuneztovari, and 1.9 and 4.7 for Aedes aegypti respectively. Mortality ranked between 95 and 100% for both mosquito species and Anopheles nuneztovari showed the highest susceptibility to the nematode parasitism.

We report a rare case of human intestinal capillariasis in a young Colombian man who presented with abdominal pain and mild, self-limited diarrhea. Capillaria eggs were visualized in the feces, and treatment with mebendazole (200 mg/d for 3 weeks) resulted in clinical and parasitological cure. To our knowledge, this is the first case in a South American person and the second case reported in Europe. This case highlights the acquisition of endemic intestinal parasitosis far away from classically considered areas of endemicity. We review the English-language literature on human intestinal capillariasis and compare findings from other cases with those from the current case.
