ACUTE DIARRHOEA ASSOCIATED WITH CRYPTOSPORIDIUM SP IN BELÉM, BRAZIL (PRELIMINARY REPORT) Edvaldo Carlos Brito LOUREIRO (1 ) , Alexandre da Costa LINHARES (1) & Leonardo MATA (2) S U M M A R Y Cryptosporidium sp was detected in faeces from three children suffering from acute diarrhoea. In two cases no other concomitant agents were detected and in a 3rd. this agent was associated with Entamoeba histolytic, Entamoeba coli, Endo¬ Jimax nana, Chilomastix mesnili and Pentatricbomonas hominis, KEY WORDS — Cryptosporidium sp — Acute diarrhoea. Cryptosporidium sp, a coccidian parasite, belongs to family Cryptosporidiidae, suborder Eimeriorina. It was firstly detected by TYZ-ZER 1 3 in 1907 and has recently been described as potentially important enteropathogen, affect-ing both children and adults throughout the world 3,4.é,]s,w. This parasite has also been found infecting a wide variety of animals W*. Recent data on Cryptosporidium infection in humans have been obtained from studies car-ried out in population groups of Costa Rica 9 and Venezuela 1 1 where it occurs more frequenty during the warmer, rainy and humid months of the year (May-August). It may also cause severe disease in patients whose immunity has been affected 12,17,18 and is a common finding among homosexual patients with AIDS (acquired im-munodeficiency syndrome) W°. In our study, specimens were obtained from 61 children (1-2 years old) who were followed for 9 months, and who belong to a low socio-economic area of Belém, Brazil. 150 Faecal samples were obtained, 94 from diarrhoeic pa-tients and 56 from non diarrhoeic control pa-tients. The detection of Cryptosporidium was by a modified Ziehl-Neelsen staining 5, as illustrated in Fig. 1A, which allows a presumptive diagno-sis. Confirmation was by both Giemsa (Pig. IB) and Auraminerhodamine staining methods. The specimens were also processed for Salmonella, Shigella and Escherichia coli (classic serotypes, enteroinvasive and enterotoxigenic strains), and for rotaviruses, enteroviruses and adenoviruses. Faeces were also examined for intestinal para-sites. Cryptosporidium was found in three (3.19%) of the 94 samples. In two cases (speci-men numbers 24.168 and 23.997) this was the only pathogen found, while in the 3rd. (num-ber 24.004) it was associated with Entamoeba histolytica, Entamoeba coli, Endolimax nana, Chilomastix mesnili and Pentatricbomonas ho-minis. All non diarrhoeic control patients were negative for Cryptosporidium. Our findings suggest that Cryptosporidium may be a causative agent of diarroea among children, since no viruses or enteropathogenic bacteria were detected in any of these cases. We would also like to stress that this is the ( 1 ) I n s t i t u t o E v a n d r o C h a g a s , F u n d a ç ã o Se rv i ços d e S a ú d e P ú b l i c a , M i n i s t é r i o d a S a ú d e , Ca ixa P o s t a l 621 — 66.000, B e l é m , PA, B r a s i l (2) I n s t i t u t o de I n v e s t i g a c i o n e s e n S a l u d ( I N I S A ) , C i u d a d U n i v e r s i t á r i a " R o d r i g o F a c i o " , U n i v e r s i d a d de C o s t a Rica C o s t a R i c a first time that this agent has been detected among patients with diarrheal syndromes in the Amazon region.

RESUMO Diarréia aguda associada a Cryptosporidium sp em Belém, Brasil (Nota prévia) Amostras de Cryptosporidium sp foram de-tectadas das fezes de três crianças com diar-réia aguda. Em dois casos nenhum outro agen-te foi registrado, concomitantemente, e no ter-ceiro caso, esse coccidio estava associado com Entamoeba histolytica, Entamoeba coli, Endo¬ limax nana, Chilomastix mesnili e Pentatricho¬ monas hominis.
