TLDR
Faecal samples from 554 bovines randomly selected at 30 farms in Aragón were examined to investigate the prevalence of Cryptosporidium and Giardia infections, finding infection rates were higher in non-diarrhoeic than in diarrhoeic calves and asymptomatic infection was always correlated with few oocysts in faeces.About:

TL;DR: The impact of cryptosporidial infections in livestock and poultry is reviewed and Cryptosporidium parvum is considered to be an important agent in the aetiology of the neonatal diarrhoea syndrome of calves, lambs and goat kids, causing considerable direct and indirect economic losses.
Journal ArticleDOI
A review of water quality concerns in livestock farming areas.
TL;DR: Results from several field studies indicate that a rational use of manure and mineral fertilisers can help reduce the pollution problems arising from livestock farming practices.
Journal ArticleDOI
Prevalence and age-related variation of Cryptosporidium species and genotypes in dairy calves.
TL;DR: The findings clearly demonstrate that earlier reports on the presence and prevalence of C. parvum in post-weaned cattle that were based solely on oocyst morphology must be reassessed using molecular methods to validate species and genotype.
Journal ArticleDOI
Prevalence of species and genotypes of Cryptosporidium found in 1-2-year-old dairy cattle in the eastern United States.
TL;DR: A lower prevalence of infection in 1-2-year-old dairy cattle than in younger cattle as well as a change in the diversity of species present are demonstrated.
Journal ArticleDOI
A longitudinal study of cryptosporidiosis in dairy cattle from birth to 2 years of age.
TL;DR: The highest prevalence of infection was at 2 weeks of age when 29 of the 30 calves were excreting oocysts, and C. parvum constituted 97% of infections in pre-weaned calves but only 4% and 0% of infection in post-weaning calves and heifers, respectively.

General biology of Cryptosporidium.
TL;DR: The life cycle of the Cryptosporidium has been confirmed using electron microscopy in this paper, but the location of the developmental stages of the parasite was interpreted as extracellular.

Threshold of detection of Cryptosporidium oocysts in human stool specimens: evidence for low sensitivity of current diagnostic methods.
TL;DR: The findings suggest that the most commonly used coprodiagnostic techniques may fail to detect cryptosporidiosis in many immunocompromised and Immunocompetent individuals.

Ethyl acetate as a substitute for diethyl ether in the formalin-ether sedimentation technique.
TL;DR: For example, this article found that the concentration of organisms with ethyl acetate was equal to or greater than that with diethyl ether in the Formalin-ether sedimentation technique.
