Abstract
Fecal samples each followed by a completed questionnaire were obtained from 233 persons representing 80 households. Using the formalinether concentration method combined with the acid-fast staining oocysts of Cryptosporidium were found in 7 (3 %) persons. 63 persons had contact to cattle, and asymptomatic cryptosporidiosis was diagnosed in 6 of them. Cryptosporidiosis was not found in any of the 51 persons with contact to some other animal but not cattle, and none of the 7 Cryptosporidium positive persons had been traveling abroad. We also obtained fecal samples from 15 calves from 7 households. Six of the calves (40 %) harbored Cryptosporidia and manifest enteritis was detected in those under age of 1 month. Five out of 14 farms had problems of neonatal calf diarrhea. Human cryptosporidiosis was more frequent on such problem farms. The results indicate that in rural population, human cryptosporidiosis is mainly asymptomatic and occurs mainly in residents of cattle-rearing farms.
Sammendrag
Avföringsprov från 233 personer representerande 80 hushåll undersöktes. Försökspersonerna fyllde också i ett frågeformulär. Med hjälp av formalin-eter koncentrering i kombination med acid-fast färgning hittades Cryptosporidium oocystor hos 7 (3 %) personer. 63 personer var i kontakt med nötkreatur, och asymptomatisk cryptosporidios diagnostiserades hos 6 av dem. Cryptosporidios konstaterades inte hos en enda av de 51 personer som var i kontakt med andra djur än nötkreatur, och ingen av de 7 Cryptosporidium positiva personerna hade rest utomlands, Vi tog också avföringsprov från 15 kalvar från 7 gårdar. 6 kalvar (40 %) hade cryptosporidier och manifest enterit påvisades hos de kalvar som var under 1 månad gamla. 5 av 14 gårdar hade problem med neonatal kalvdiarre. Human cryptosporidios var vanligare på sådana problemgårdar. Resultaten visar att human cryptosporidios hos en landsortsbefolkning i huvudsak är asymptomatisk och främst förekommer hos invånade på gårdar med nötkreatur.
