Description
  • Age-related and housing-dependence of naturally acquired cryptosporidiosis on dairy and beef farms were described. The prevalence of Cryptosporidium in pre-weaned and post-weaned calves was determined. Cryptosporidium oocysts were differentiated on morphological criteria. Of the 7021 specimens collected, 25.8 % were positive for Cryptosporidium oocysts; 8 % of samples for C. parvum and 17.8 % for C. andersoni. Pre-weaned dairy calves had higher infection levels of C. parvum than pre-weaned beef calves. The prevalence of C. parvum ranged from 1.4 to 56.5 % on dairy farms. Only three cases of C. parvum oocysts shedding on beef farms were found. Only one case of C. andersoni infection in pre-weaned calves was detected. The prevalence of C. andersoni reached 35.5 % on dairy farms and 61.7 % on beef farms. Calves that were on pasture all year long, had a lower probability of C. andersoni infection than those calves kept in a cowshed during the winter season.

  • Byl posouzen vliv věku a technologie chovu na výskyt kryptosporidiových infekcí u telat před a po odstavu u mléčných a masných plemen skotu. Oocysty kryptosporidií byly odlišeny na základě morfologie. Z celkového množství 7021 vyšetřených vzorků trusu bylo 25,8 % pozitivních na oocysty kryptosporidií; 8 % C. parvum a 17,8 % C. andersoni. Byl zjištěn vyšší výskyt C. parvum u telat před odstavem mléčných plemen než u masných. Prevalence C. parvum se na mléčných farmách pohybovala od 1,4 do 56,5 %. Byly zjištěny pouze tři případy výskytu C. parvum u masných telat. Prevalence C. andersoni dosahovala 35,5 % na mléčných a 61,7 % na masných farmách. U telat chovaných celoročně na pastvě byla zjištěna nižší pravděpodobnost infekce C. andersoni než u telat, která byla během zimního období chována ve stáji. (cs)
