Global Prevalence of Cryptosporidium Infections in Cattle and C. parvum genotype distribution: A Meta-Analysis
Background
The protozoan parasiteCryptosporidiumis the causative agent of a severe diarrhoeal disease, called cryptosporidiosis.Cryptosporidiumspecies are capable of infecting a wide range of hosts including humans and livestock. In cattle, cryptosporidiosis is now one of the most important causes of neonatal scour globally, either as a sole agent or co-infecting with other pathogens. Cryptosporidiosis is considered globally endemic, with a prevalence ofCryptosporidiumin stool samples from 13% to 93% in European cattle. This disease has a significant economic burden, with costs associated with veterinary diagnosis, medication, increased labour, animal rearing and supplemental nutrition as well as being associated with reduced long-term growth rate in calves, causing huge economic losses in livestock industry. Moreover, cattle act as a zoonotic reservoir forCryptosporidium parvum, a species that is capable of infecting humans as well. As such, monitoring the prevalence ofCryptosporidiumin cattle is important due to the public health risk and financial burden the clinical disease causes.
Methods
Publications reporting on the prevalence ofCryptosporidiumin cattle were collected from PubMed and Google Scholar. Information regarding the species ofCryptosporidiumin positive samples, the genotype ofC. parvumfound in samples, and the diarrhoeic status of the cattle was collected where available. A total of 279 publications were collected for this meta-analysis from six continents and 65 countries to provide an estimation for global bovineCryptosporidiumprevalence.
Results
A 25.5% global prevalence ofCryptosporidiuminfection was reported, withC. parvumbeing the most frequently identified species, particularly the IIa subfamily. Diarrhoea was reported in 14,141 cattle samples, of which 36.0% tested positive forCryptosporidium. Regarding symptoms, we found that in countries reporting over 50% of diarrhoeic positive cattle,C. parvumwas the most common species.
Conclusions
Continued monitoring and reporting ofCryptosporidiumin cattle are crucial for both public health and economic reasons. Consequently, efforts should focus on underreported regions and the development of control measures to reduce prevalence and limit zoonotic transmission.
