Soil survival of toxoplasma oocysts in Kansas and Costa Rica.
TLDR
Oocyst infectivity was quantitated in the Kansas deposit over a period of 18 months, including two winters, and the concept that Toxoplasma infectivity in nature may be increased logarithmically by cats is supported.

[Prevalence of Cyclospora sp., Cryptosporidium sp, microsporidia and fecal coliform determination in fresh fruit and vegetables consumed in Costa Rica].
TLDR
The results show the importance of introducing in the country Good Agricultural Practices, especially due to the resistance of Cryptosporidium and Cyclospora to disinfecting agents, showing the risk they represent to Public Health.

Molecular systematics and phylogeography of Cebus capucinus (Cebidae, Primates) in Colombia and Costa Rica by means of the mitochondrial COII gene
TLDR
The authors' molecular population genetics data do not agree with the existence of two well‐defined subspecies in Central America (limitaneus and imitator) and this Central America mt haplogroup showed significantly less genetic diversity than the Colombianmt haplogroups.

[Seasonality of parasites and intestinal bacteria in vegetables that are consumed raw in Costa Rica].
TLDR
Only lettuce and cilantro levels showed a positive linear correlation between occurrences of intestinal parasites and fecal coliforms, and the greater percentage of positive samples was found during the dry season.

[Chemical and biological evaluation of the effect of plant extracts against Plasmodium berghei].
TLDR
Extracts from thirteen species of plants were evaluated by "in vivo" antimalarial test against plasmodium berghei effects and compounds identified include flavanoids, coumarins, mellilotic acid and iridoids which some kind of biodynamic activity has previously been reported.

Lack of multiplication of Toxoplasma in macrophages of rats in vitro.
TLDR
The use of highly specific ES antigens in combination with a sensitive ELISA method offers a reliable diagnostic tool for toxocariasis and apparently the antibodies demonstrated against ES antigen reflect acute and active infection.

Toxoplasma gondii (Eucoccidia: Sarcoystidae) dissemination pattern in rats after oral infection with oocysts of an avirulent strain.
TLDR
After 30 days, the parasite was detected only in rat heart and brain, while in mice it persisted in fluids and all organs, so differences in Toxoplasma gondii dissemination in white rats and mice after oral oocyst inoculation are described.
