“…in calves from dairy farms in the State of São Paulo (THOMAZ et al, 2007). Huber et al (2005) found 10 positive samples (5.6%) in dairy cattle in the State of Rio de Janeiro, while Langoni et al (2004) found 21.2% of Cryptosporidium positivity in 203 fecal samples of calves from several farms in the State of São Paulo. The exclusive occurrence of C. andersoni in bovines in this study is a result which is markedly different from those reported elsewhere in which C. parvum predominates.…”

The aim of this study was to assess the occurrence of Cryptosporidium in domestic animals in rural properties surrounding rain forest fragments within the municipality of Teodoro Sampaio, southeastern Brazil. Conventional sucrose flotation method followed by molecular characterization of the parasites by sequencing PCR products amplified from SSU rRNA gene were used. Stool samples were collected from domestic animals raised as pets and livestock in all rural properties surrounding three forest fragments. Samples from cattle (197), equine (63), pigs (25), sheep (11), and dogs (28) were collected from 98 rural properties. The frequency of occurrence of Cryptosporidium within each animal species was 3.0% (6/197) among cattle and 10.7% (3/28) among dogs. Cryptosporidium was not detected in stool samples from equine, sheep, and pigs. All sequences obtained from the six samples of calves showed molecular identity with Cryptosporidium andersoni while all sequences from dog samples were similar to C. canis. The frequency of occurrence of Cryptosporidium in these domestic animal species was low. The absence of C. parvum in the present study suggests that the zoonotic cycle of cryptosporidiosis may not be relevant in the region studied. The presence of Cryptosporidium species seldom described in humans may be, otherwise, important for the wild fauna as these animals are a source of infection and dissemination of this protozoan to other animal species. The impact and magnitude of infection by C. andersoni in wild ruminants and C. canis in wild canids have to be assessed in future studies to better understand the actual importance of these species in this region.

“…In Latin America, Cryptosporidium prevalence varied from 21.2 to 25% in calves younger than 30 days old (MALDONADO-CAMARGO et al, 1998;LANGONI et al, 2004;ALMEIDA et al, 2008;CARDOSO et al, 2008). Similar values have been reported in Argentina (BELLINZONI et al, 1990;DEL COCO et al, 2008) and are in accordance with the current study.…”

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.

“…Different viral, bacterial and protozoal enteropathogenic agents, in associated infections or not, can cause diarrhea in the neonatal calf (LANGONI et al, 2004). Regardless of which agent(s) is (are) involved, the elimination of watery stools causes dehydration, electrolyte imbalances, and metabolic acidosis, which are marked if the diarrhea is prolonged (SMITH, 2009).…”

INTRODUCTIONThe fluid therapy is indicated for the treatment of diseases that determine dehydration and electrolyte and acid base imbalances and is; therefore, commonly used in ruminants medicine, especially in calves. The goals of the replacement of fluids and electrolytes are the correction of present imbalances, the restoration of blood volume and adequate tissue perfusion and the treatment of shock in animals (CONSTABLE, 2003).Fluid and electrolyte replacement can be performed by enteral hydration (EH) or by intravenous infusion (IV). The EH has advantages over IV and should be the modality of choice whenever possible (BERCHTOLD, 2009). It is easier and cheaper, and should be considered equally effective, whenever the gastrointestinal transit is present and dehydration is not marked (CONSTABLE, 2003).Diarrhea is the main disease that affects neonatal calves and can cause mortality due to the imbalances that are installed (SMITH, 2009). Economic losses are related to the death and to additional costs with drugs, labor and veterinary care. When animals survive, the losses occur due to low performance and reduction in the daily body weight gain (MILLEMANN, 2009).In the treatment of diarrheic calves the therapy with oral electrolyte solutions (OES) is the most important measure. The goal is to correct the dehydration, to reverse the hyponatremia and the CLINIC AND SURGERY
