Detection of Cryptosporidium oocysts in extra-intestinal tissues of sheep and pigs.
Extra-intestinal infections by Cryptosporidium parvum have been detected in pigs and sheep. Detection was carried out by imprints of the mucosa of different organs and viscera in 55 sheep and 57 pigs slaughtered at three abattoirs in Zaragoza (northeast Spain). Imprints were stained by using a modified Ziehl-Neelsen technique. In addition to intestinal infections, cryptosporidial oocysts were found in the gall-bladders of two pigs which were 2 months old, and in some organs of sheep aged 5 days or more, including the gall-bladder (5), mesenteric lymph nodes (2), trachea (7), lung (3) and the uterus of one lamb.
