A NEW COCCIDIAN (APICOMPLEXA: EIMERIIDAE) IN THE CRITICALLY ENDANGERED CENTRAL AMERICAN RIVER TURTLE (DERMATEMYS MAWII) IN BELIZE.

As part of a biannual health examination, coprological samples from 3-mo-old Central American river turtles, Dermatemys mawii (Gray, 1847) in a breeding program in Belize, Central America, revealed a previously undescribed coccidian (Apicomplexa) in 17 of 46 (37%) samples. Of 3 positive fecal samples transported to the University of Florida, coccidian oocysts were observed in 1 sample. Sporulated oocysts were measured and described, and using polymerase chain reaction (PCR), an approximately 400-base pair (bp) region of both the small subunit (18S) ribosomal RNA gene and 1,200-bp region of the internal transcribed spacer (ITS) gene were amplified in all 3 samples and their products were sequenced.

Prevalence of Toxocara spp., Toxascaris leonina and ancylostomidae in public parks and beaches in different climate zones of Costa Rica.

This epidemiological study was conducted in different regions of Costa Rica to determine the prevalence of the developmental stages of potential zoonotic intestinal helminths of dogs and cats in public places. Samples were collected within three main climate zones including rural and urban areas during both the rainy and the dry season. Faecal and environmental samples were taken from 69 parks and beaches.
