| Summary: | The prevalence of Cystoisospora suis in lactating piglets and their dams in pig farmsin the central region of Venezuela was determined. The study was conducted in farms ofthree sizes with a history of neonatal diarrhea: small (<150 sows), medium (150-500 sows)and large (>500 sows) farms. A total of 572 litters and their mothers were examined.
Samples were cultured in 2.5% potassium dichromate and latter processed by the flotation-centrifugation technique using a NaCl saturaded solution. C. suis was found in 55 farms(82.1%) and 210 litters (36.7%), with the highest prevalence values in the first two weeksof life (p<0.05), but without statistical differences between farm sizes. Moreover, 9.4% ofthe sows were infected and of these, 89% of the litters were positive to C. suis, giving asignificant correlation between the positivity of piglets and their mothers (r=0.55; p<0.05). The results show that C. suis is widely distributed in the central region of Vene-zuela, regardless of farm size.
Se determinó la prevalencia de Cystoisospora suis en lechones lactantes y cerdasmadres en granjas porcinas de la región central de Venezuela. El estudio se condujo engranjas de tres tamaños y con antecedentes de diarrea neonatal: granjas pequeñas (<150madres), medianas (150-500 madres) y grandes (>500 madres). Se examinaron 572 cama-das y sus madres. Las muestras se cultivaron en dicromato de potasio al 2.5% y procesa-das mediante la técnica de flotación-centrifugación, utilizando una solución saturada deNaCl enriquecida con solución azucarada. C. suis se encontró en 55 granjas (82.1%) y 210camadas (36.7%), con los mayores valores de prevalencia en las dos primeras semanas devida (p<0.05), pero sin diferencias estadísticas entre tamaños de granja. El 9.4% de lascerdas se encontraron infectadas y, de estas, el 89% de las camadas resultaron positivasa C. suis, dando una correlación significativa entre la positividad de lechones y susmadres (r=0.55; p<0.05). Los resultados demuestran que C. suis se encuentra ampliamen-te distribuida en la región central de Venezuela, indistintamente del tamaño de la granja.
