Una muestra de heces obtenida por evacuaci\u00f3n espont\u00e1nea fue analizada mediante la t\u00e9cnica de examen directo y m\u00e9todo de concentraci\u00f3n de Willis. Se encontraron 150 personas parasitadas (36,14%), de ellas 107 (25,78%) con B. hominis. No se observ\u00f3 predilecci\u00f3n por el sexo (p &gt; 0,05), pero s\u00ed con relaci\u00f3n a la edad, siendo las personas de 18 a 27 a\u00f1os las m\u00e1s afectados (ji\u00b2 = 12,17; g.l. = 4). En el 71,02% de los casos se encontr\u00f3 como par\u00e1sito \u00fanico y en 28,98% de los casos asociados a otros par\u00e1sitos, siendo el m\u00e1s frecuentemente asociado Giardia lamblia (2,41%). En la mayor\u00eda de las personas parasitadas (85%) el protozoario se observ\u00f3 en un n\u00famero menor de cinco c\u00e9lulas por campo. Se concluye que B. hominis es un par\u00e1sito frecuente en manipuladores de alimentos del Municipio Caron\u00ed, Estado Bol\u00edvar, Venezuela.<\/jats:p>","DOI":"10.1590\/s0102-311x2003000600016","type":"journal-article","created":{"date-parts":[[2007,5,4]],"date-time":"2007-05-04T20:44:15Z","timestamp":1178311455000},"page":"1721-1727","source":"Crossref","is-referenced-by-count":11,"title":["Prevalencia de Blastocystis hominis en vendedores ambulantes de comida del municipio Caron\u00ed, Estado Bol\u00edvar, Venezuela"],"prefix":"10.1590","volume":"19","author":[{"given":"Ixora","family":"Requena","sequence":"first","affiliation":[{"name":"Universidad de Oriente, Venezuela"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yessica","family":"Hern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Universidad de Oriente, Venezuela"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mario","family":"Ramsay","sequence":"additional","affiliation":[{"name":"Universidad de Oriente, Venezuela"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carmen","family":"Salazar","sequence":"additional","affiliation":[{"name":"Universidad de Oriente, Venezuela"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodolfo","family":"Devera","sequence":"additional","affiliation":[{"name":"Universidad de Oriente, Venezuela"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","first-page":"817","article-title":"Blastocystis hominis among apparently healthy food handles in Jeddah, Saudi Arabia","volume":"27","author":"AMIN A.
