The animals studied were classified into 12 age groups: &lt;1\u2003month (53); 1\u20135\u2003months (30); 6\u201311\u2003months (31); 12\u201316\u2003months (72); 17\u201320\u2003months (64); 21\u201324\u2003months (96); 3\u2003years (94); 4\u2003years (74); 5\u2003years (67); 6\u2003years (67); 7\u20138\u2003years (63) and 9\u201313\u2003years (23). Oocysts of<jats:italic>Cryptosporidium<\/jats:italic>spp. were identified in 104 animals (14.2%) distributed throughout all of the age groups and from 40 different farms (66.7%). The percentage of cattle infected ranged between 58.5% in calves &lt;1\u2003month and 7.9% in 7 to 8\u2010year\u2010old cows, i.e. the percentage of infection decreased significantly (<jats:italic>P<\/jats:italic>\u2003&lt;\u20030.05) with increasing age. The intensity of infection in animals older than 1\u2003month ranged between 10 and 5924\u2003oocysts\/g of faeces and there were no significant differences between the different groups. Cysts of<jats:italic>Giardia duodenalis<\/jats:italic>were identified in 221 animals (30.1%) from 56 farms (93.3%). The parasite was detected in all age groups, at rates of infection ranging between 21.8% (9\u201313\u2003years) and 56.7% (1\u20135\u2003months), although these differences were not statistically significant. The intensity of infection ranged between 7 and 15\u2003412\u2003cysts\/g of faeces, with the number of cysts shed being significantly higher (<jats:italic>P<\/jats:italic>\u2003&lt;\u2003 0.05) in calves &lt;1\u2003month than in calves aged 1\u20135\u2003months. Significant associations between parasitisation by<jats:italic>Cryptosporidium<\/jats:italic>spp. or<jats:italic>G. duodenalis<\/jats:italic>and the consistency of the faeces were only found in calves aged &lt;1\u2003month and 1\u20135\u2003months. Concurrent infections were more prevalent in the groups of calves of 1\u20135\u2003months (23.3%) and 6\u201311\u2003months (25.8%).<\/jats:p>","DOI":"10.1111\/j.1439-0450.2006.00946.x","type":"journal-article","created":{"date-parts":[[2006,5,24]],"date-time":"2006-05-24T07:34:51Z","timestamp":1148456091000},"page":"244-246","source":"Crossref","is-referenced-by-count":46,"title":["Prevalence and Intensity of Infection of<i>Cryptosporidium<\/i>spp. and<i>Giardia duodenalis<\/i>in Dairy Cattle in Galicia (NW Spain)"],"prefix":"10.1111","volume":"53","author":[{"given":"J.
