ABSTRACT
Cyclospora cayetanensis (Ortega, Gilman & Sterling, 1994), es el agente emergente de la ciclosporiasis, nueva afección diarreica descrita como aguda y autolimitada, de dos a seis semanas de duración en inmunocompetentes y diarrea crónica intermitente en pacientes con sida. Esta afección y su agente han sido notificados recientemente en Uruguay, afectando a viajeros provenientes de áreas reconocidamente endémicas para este nuevo protozoario coccidio entérico. En la presente comunicación se examina la totalidad de la casuística conocida en el país, y se concluye que C. cayetanensis es en Uruguay un agente de diarrea del viajero, sin registro de ocurrencia autóctona hasta la fecha.
Summary Cyclospora cayetanensis (Ortega, Gilman, and Sterling, 1994) is the emergent agent of cyclosporiasis, a new acute and self-limited diarrhoeal disease. It lasts from two to six weeks when affects immunocompetent individuals and it causes chronic intermittent diarrhea in AIDS patients. This disease and its etiologic agent have been recently reported in Uruguay, affecting travellers coming from previously known endemic areas. In the present work, the whole number of cases in the country is reported. We conclude that C. cayetanensis is an agent of the traveller's diarrhoea in Uruguay, without occurrence of native cases so far.
Résumé Cyclospora cayetanensis Ortega, Gilman& Sterling, 1994), c'est l'agent émergent de la cyclosporiasis, nouvelle mala-die diarrhéique décrite comme aigue et auto-limitée, de deux à six semaines de durée en immunocompétentes et diarrhée chronique intermittente chez des patients avec Sida. Cette affection et son agent ont été récemment décrits en Uruguay et elle atteint des voyageurs qui viennent d'endroits reconnus comme endémiques pour ce nouveau protozoaire coccidien entérique. Dans cette étude, on examine toute la casuistique connue dans le pays, et on conclut que C. Cayetanensis est en Uruguay un agent de diarrhée du voyageur, n'ayant pas de registre autochtone jusqu'à présent.

This paper describes population structure, spatial distribution and habitat selection of wild and peridomestic populations of Triatoma rubrovaria (Blanchard, 1843). Field studies were carried out at Las Piedras and La Bolsa in the Northern Department of Artigas, Uruguay. A semicircular sampling area, divided in seven or eight triangular sectors was sequentially examined from October 1990 to November 1991. At Las Piedras (typical wild habitat) 1063 T. rubrovaria bugs were collected from 84 of the rocky outcroops ("pedregales"). Abundance varied by season peaking in October-November (spring). Throughout the year, most of the population was made up of third, fourth and fifth instar nymphs; adults were found from October to March. In the peridomestic environment of La Bolsa, however T. rubrovaria was less common and showed a more irregular instar distribution. Colonized ecotopes, were those close to houses. In both sites T. rubrovaria was mainly associated with the geckonid Homonota uruguayensis and the cockroach Blaptica dubia.

Triatoma delpontei (Romaña & Abalos, 1947) (Hemiptera, Triatominae) is an ornithophilic sylvatic with a particular association to the psittacid Myiopsitta monachus (Boaddert, 1783). It is found in the continental biogeographical province of the Chaco, where it inhabits the nests or M. monachus, in subtropical xerophytic forests. The authors report the first finding of T. delpontei in Brasil, in the "campanha" region of the State or Rio Grande do Sul (Barra do Quarai, Uruguaiana), on the right bank of the River Cuareim, not far from de Uruguayan border.
