“…Similar values have been reported in Argentina (BELLINZONI et al, 1990;DEL COCO et al, 2008) and are in accordance with the current study. Bellinzoni et al (1990) studied 452 fecal samples of calves with diarrhea from 33 dairy farms and 36 beef herds from different Argentina provinces, while the later study, involved 280 calves from one dairy farm.…”

“…either from the postparturient dam or from hutches contaminated with oocysts from a previous calf (MALDONADO-CAMARGO et al, 1998). Under confinement, the initial exposition to infective oocysts seems to take place in the maternity pen, or after being transferred to the cowshed, indicating a heavy environmental contamination in the calving area (DEL COCO et al, 2008). Under Argentina conditions, the soil parasitic burden may be critical as exposure because the calf paddock area in all herds studied was not subjected to rotation as newborn calves were introduced to the system.…”

“…has been reported previously in Argentina (BELLINZONI et al, 1990;DEL COCO et al, 2008), there is little knowledge about this protozoa and Giardia in calves in the dairy region of central Argentina. Also, no previous research has examined the involvement of herd and calf factors on prevalence as well as the herd prevalence clustering according to soil type.…”

The objectives of this study were to estimate calf and herd prevalence of Cryptosporidium spp. and Giardia spp., the herd prevalence clustering, spatial distribution according to soil type and shedding patterns in dairy calves from Cordoba, Argentina. Six hundred twenty calves younger than 7 weeks of age from 43 dairy herds were sampled. Samples were processed with the formol-ether and modified Ziehl-Neelsen techniques. Univariate analysis and Kruskall-Wallis tests were used. Factors associated were subjected to multivariate analysis with calf shedding intensity as the response variable. Clustering of herd prevalence was assessed by a scan method, and spatial analysis was applied to explore the overlapping of high prevalence herds and soil type. Overall calf prevalence for Cryptosporidium spp. oocysts and Giardia spp. cysts were 19.35% (95% CI: 16.14; 22.54) and 34.50% (95% CI: 30.69; 38.34), respectively. Calves younger than two weeks of age were almost four times more likely to be infected with Cryptosporidium, in comparison to older ones (RR: 3.78, 95% CI: 2.27; 6.26). Giardia spp. shedding showed a similar age pattern (RR: 1.33, 95% CI: 1.02; 1.75). A primary cluster of high Cryptosporidium prevalence was found, and high prevalence herds were located in areas with poor drained soil.

“…The parasite has not been found in animals younger than 4 days old (Sturdee et al, 2003;Kvác et al, 2006) and is only detected after 7 days of life (Del Coco et al, 2008). The highest reported infection rates are with calves between 7 and 14 (Kvác et al, 2006) or 8 and 21 days old (Del Coco et al, 2008).…”

El objetivo fue determinar la prevalencia y posibles factores de riesgo asociados a la excreción de ooquistes de Cryptosporidium spp en excremento de bovinos Holstein en fincas de producción lechera de Boyacá, Colombia. Se colectaron 100 muestras de materia fecal de bovinos hembras mediante estimulación rectal. Con la técnica de Ziehl Neelsen modificada se determinó la excreción de ooquistes de Cryptosporidium spp. Para conocer los posibles factores asociados se usó la prueba de Ji cuadrada teniendo como variable dependiente la presencia de ooquistes de Cryptosporidium spp y como independientes la presencia de diarrea (si, no), edad (<12 meses, >12 meses), finca de procedencia (1, 2, 3, 4) y estado reproductivo (gestante, vacía). Las variables con P<0,05 fueron analizadas mediante regresión logística. La prevalencia general de bovinos excretando ooquistes de Cryptosporidium spp fue de 48 % (48/100). Las explotaciones ganaderas estudiadas presentaron prevalencias de 11.1, 43.8, 50.8 y 66.6 % para las explotaciones 1, 2, 3 y 4 respectivamente (P>0.05). Las variables que durante el análisis con X2 tuvieron valores P<0.05 fueron edad y presencia de diarrea. Los bovinos con diarrea (OR= 2.99, P= 0.038) y <12 meses de edad (OR=9.42, P= 0.037) fueron los factores asociados a la excreción de ooquistes de Cryptosporidium spp. Los bovinos de fincas lecheras de Boyacá, presentan alta prevalencia de excreción de ooquistes de Cryptosporidium spp; bovinos con diarrea y menores de 12 meses de edad son los que presentaron el parásito con mayor frecuencia.
