Para contribuir al conocimiento de la criptosporidiosis, comprender la prevalencia de Cryptosporidium spp. en terneros y asociar la presencia de ooquistes a diferentes factores ambientales, se realizó un estudio, en el cual, se recolectaron 151 muestras de heces de terneros, de hasta un mes de nacidos, en la región Sabana Centro (Cundinamarca). Para identificar los ooquistes de Cryptosporidium spp., se empleó la técnica de Ziehl Neelsen modificada. El 22% de las muestras fue positivo y en el 83% de las fincas había, al menos, un animal infectado. El análisis estadístico mostró una asociación entre la consistencia de la materia fecal y la presencia de ooquistes de Cryptosporidium spp. (X2 16,3; p< 0,01). La fuente de agua de las fincas reveló una asociación estadísticamente significativa, cuando se comparó con la presencia de ooquistes en las heces (x2 11,79; p <0,008), siendo un factor de riesgo el agua de acueducto; contrario a lo esperado, el agua tratada mostró tener un efecto protector. Así mismo, se consiguió una relación estadísticamente significativa entre el tipo de alojamiento y la presencia de ooquistes (x2 7,23; p <0,02), con una mayor probabilidad de hallar ooquistes en los animales que estaban en estaca que en aquellos que permanecían estabulados (OR > 4,03). Los resultados obtenidos confirman que la infección por Cryptosporidium spp. está ampliamente distribuida en los hatos lecheros de la zona geográfica de estudio.

In the Chiquinquirá Valley a study that sought to contrib-ute 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 evalu-ated, 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 rela-tionship was found (p <0.05) in the case of the variables: township, animal age, source of water and stool consisten-cy. 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 oo-cysts 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 stud-ies. 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.

Cinco terneros de raza pardo suizo con brahman nacidos en la finca agropecuaria alfa ubicada en Ricaurte Cundinamarca presentaron Letargo, inapetencia y diarrea. Al realizar el examen clínico había deshidratación, fiebre, melena, hematoquecia, letargo. Se realizo necropsia a uno de los terneros que murió donde hubo Cambios autolíticos, colon con necrosis, observación de estructuras redondas con pared celular compatibles con estadios de Eimeria. De acuerdo con el diagnóstico se realizó el tratamiento pertinente que incluía fluidoterapia con ringer lactato, trimetoprim y sulfametoxazol intramuscular, estreptomicina sulfato oral, subsalicilato de bismuto, amprolio. Por ende, se concluye que según la anamnesis y las manifestaciones clínicas no se determinó como diagnóstico más probable coccidia por ende el tratamiento en algunos casos no tuvo resultados positivos.

Cryptosporidiosis is a disease caused by Cryptosporidium spp that affects humans and a variety of vertebrate animals, being one of the most important causes of diarrhea and death in children and calves. One of the tools to know the potential of zoonotic distribution of circulating Cryptosporidium is the molecular characterization. For the most part, livestock are infected with Cryptosporidium parvum subtype IIa, the molecular characterization of circulating Cryptosporidium can allow the evaluation of zoonotic distribution potential, as well as determine if the geographical area and its specific environmental conditions can influence the genetic composition of the parasite, therefore, this work aimed to evaluate the association between the gp60 of Cryptosporidium parvum with the presentation of diarrhea, age of the calf and geographical region origin of the sample. For this work, 51 sequences of the gp60 glycoprotein of C. parvum amplified from fecal matter were analyzed, which came from calves coming from 51 farms of the Cundiboyacense region using work tools programs such as Bioedit, BLASTn, Genbank, Mega, Clustal, analyzing the sequences with Neighbor-Joining and Tajima's methods. As results, the distribution of the sequences was found to be homogeneous around the Cundiboyacense region, where subtype IIaA18G5R1 was the most found. There was no statistically significant relationship between gp60 and the variables proposed on this study. There is no treatment for this disease, which motivates every day to carry out new studies and to implement new preventive measures.

To contribute to the knowledge of cryptosporidiosis, recognize the prevalence of Cryptosporidium in calves and associate the presence of oocysts to the fecal consistence, a study was executed, collecting 170 samples of fecal material of calves, aged between five and 35 days, within 41 ranches located in the Ubaté-Chinquinquirá valley. In order to identify the Cryptosporidium oocysts the Heine technique was employed. Thirty seven (22%) of the 170 calves were positive and 18 (44%) of the 37 ranches showed at least one positive animal. The statistical analysis revealed an association between age and the presence of oocysts (X2 15; P<0.01). The highest prevalence was found in calves between age 11 to 15 and 16 to 20 days, presenting significant differences when comparing these two age groups with the other ones examined. Statistically, no association between the presence or absence of Cryptosporidium and the consistence of the fecal material was detected (X2 1.3; P>0.25). When comparing the fecal consistence with the infection intensity, no association was found (X2 1.7; P>0.42), result that confirms the high number of asymptomatic calves in the Ubaté-Chiquinquirá valley. The outcome of this research indicates an ample distribution of Cryptosporidium infection in the cattle ranches of the geographic area under survey.

Cryptosporidium spp. is a protozoan parasite that has been shown to have zoonotic potential and be one of the main public health problems, since it can cause serious outbreaks in humans, due to its importance in public health a study was developed in the Ubaté - Chiquinquirá Valley Colombia, where different variables were analyzed such as the number of animals, water source, age, herd size, stool consistency, municipality and housing. We sampled 136 animals between 3 and 30 days of age in 34 farms, fecal samples were taken directly from the rectum, 136 animals sampled, 9 were positive to Cryptosporidium spp, finding a prevalence of 6.6% in animals. The statistical analysis showed a statistically significant relationship (p <0.05) between the presence of oocysts and the municipalities where the samples were taken, in terms of the age of the calves, although most of the authors report that the most frequent age to find oocysts of Cryptosporidium spp., it is 11-20 days, in the present study no positive animal was found, however, this does not mean that oocysts can not be found at this age. Regarding the other variables, no statistically significant relationship was found. In order to assess whether rainfall affects the presence of this parasite, the volume of rainfall in the same geographical area was compared in the years in which the studies were carried out, being for this study the year 2016 and the months of June and July and for the study conducted by Avendaño et al (2012) were the months of February, March and April, finding that there is no statistically significant relationship in terms of the volume of rainfall and the presence of oocysts. Reaffirming the presence of Cryptosporidium spp in the valley of Ubaté - Chiquinquirá and since there is no effective treatment for infection in both animals and humans, it is important to bear in mind the importance of preventing its transmission, to avoid possible outbreaks.
