MONTANO, Juan  y  AVENDANO, Catalina. CONTRIBUTION TO THE KNOwLEDGE OF THE EPIDEMIOLOGY OF CRYPTOSPORIDIOSIS IN THE CHIQUINQUIRÁ VALLEY. rev.udcaactual.divulg.cient. [online]. 2012, vol.15, n.2, pp.391-398. ISSN 0123-4226.

In the Chiquinquirá Valley a study that sought to contribute to the characterization of bovine cryptosporidiosis was carried out. The proportion of positive animals and farms, housing variables, water origin, age, herd size, permanence with mother, food and consistency of the stool, were taken into account. Calves aged less than 30 days old, were evaluated, taking 190 stool samples directly from the rectum in 34 farms. Parasite oocysts were observed in 7% and 24% of animals and farms, respectively. Statistically significant relationship was found (p <0.05) in the case of the variables: township, animal age, source of water and stool consistency. In Simijaca the risk to find the parasite, when compared with Chiquinquirá and San Miguel was found to be ten times higher. Calves aged between 11-20 days were six times more likely to eliminate the parasite compared with the individuals of the other age groups. As for the water quality a probability of detecting oocysts was nine times more likely in animals handled with treated water than in those who consumed well water. Additionally, the possibility to find the parasites oocysts in liquid stool than in other consistence was four times higher. The presentation of bovine cryptosporidiosis in the region was found to be lower compared to previous studies. It is recommended to avoid overcrowding, to isolate and treat sick animals and to monitor the possible occurrence of symptoms in individuals who lived with the infected group and finally implement quarantine measures and disinfection of the areas.
