TLDR
Trypanosoma cruzi antibody presence was studied in pet and stray dogs from endemic and non endemic zones and twelve percent of stray dogs were positive independent of the procedence. Expand
Adaptación natural de rata blanca a Toxoplasma gondii

Parasitismo intestinal en monos tití o ardilla Saimiri oerstedii (Primates: Cebidae) de Costa Rica
TLDR
Las heces eran colectadas cuando el animal evacuaba en forma natural o bajo el esti´mulo necesario, y el parasitismo como un factor de riesgo ma´s en su extincio´n, asi´ encontrados son iguales a los del ser humano. Expand
Especies de Eimeria (Eucoccidida:Eimeriidae) en la rata de milpa Sigmodon hispidus de Costa Rica
TLDR
This is the first repor! of tbese coccidian parasites for Costa Rican rats collected from Ojo de Agua and Canas, Guanacaste. Expand
Efecto inmunosupresor de Trypanosoma lewisi (Kinetoplastidae) sobre la multiplicación de Toxoplasma gondii (Sarcocystidae) en macrófagos alveolares y peritoneales de rata blanca
TLDR
The immunosuppressant effect of T. lewisi (Kinetoplastidae) infection on the multiplication of Toxoplasma gondii (Sarcocystidae) on alveolar and peritoneal macrophages of the white rat was compared and immunity against T. gond ii is similar between both phagocytes, but the time of infection and the compartment where the cells are located, makes the difference in the response time.

Infección de fibroblastos de piel de animales con distinto grado de susceptibilidad a Leishmania infantum y Leishmania mexicana (Kinetoplastida: Trypanosomatidae)
TLDR
Fibroblasts could work as host cells for parasite survival and permanency in the infected animals, and presence of amastigote multiplication inside of parasitophorus vacuole probes a true parasite transformation. Expand
Infestación por vectores de la Enfermedad de Chagas en cuatro zonas endémicas de la meseta central de Costa Rica
TLDR
An entomological search for vectors of Chagas` disease was performed in 157 houses located in 4 endemic regions of the Central Plateau of Costa Rica and 13 of the houses were positive for Triatoma dimidiata the only triatomine species found, suggesting the impact of T. cruzi infection in Costa Rican populations could be low and the prevalence of the disease could be linked to zoonotic cycles.
