Cryptosporidiosis in calves and goat kids: research concerning diagnosis, epidemiology, and etiopathogenesis
Group No. 1 was made of 10 calves presenting symptoms of catarrhal enteritis
Group No. 2 was made of 9 calves presenting symptoms of hemorrhagic enteritis
Results
Cryptosporidium parvum is the most common pathogen involved in the Neonatal
Diarrhea Syndrome, with a prevalence of 35.45% of the total cases, in 16.36% of them as
a sole pathogen, and in 19.09% of the cases in association with other enteropathogens.
The Rotavirus infection was found in 17.27% of the total cases, from which in 7.27% as a
sole pathogen, and in 10% in association with other enteropathogens. The infection with
Coronavirus was identified in 17.27% of the total cases, from which in 2.73% as a sole
pathogen, and in 14.54% in association with Cryptosporidium parvum. The Factor 5 E.
coli infection was identified in only 1.82% of the total cases. Out of the total sample
cases, 52.27% were negative for all 4 of the studied enteropathogens.
The prevalence of Cryptosporidiosis was highest in the Cluj County (50%), while
the Rotavirus and Coronavirus infections had the highest prevalence in Satu Mare
County, with 24.24% and respectively 39.39% (figure 5).
The infection with Cryptosporidium parvum was most common at the age of 1-2
weeks (56.57%) and 2-3 weeks (46.15%). The infections with Rotavirus and respectively
Coronavirus were mostly identified at the age of 1-2 weeks, in about 35.13% respectively
29.72% of the cases. Factor F5 E. Coli infection was identified only in the age group of
less than a week, in two calves age 5, and respectively 7 days old (figure 6).
