Abstract
The present study was conducted on 124 newly born calves (28 buffaloe calves, 19 Frezian calves and 77 Native calves), beside these number 46 calves were kept as control group (15 buffaloe, 15 Frezian and 16 Native). The age of these animals ranged from one day to 4 months old, they examined during the period from May 2004 to March 2005, these animals belonged to the farm of faculty of Agriculture, Veterinary teaching hospital and villages of Assiut Governorate.
The results of parasitological examination in the present study cleared that the animals were infested with Cryptosporidium parvum (The oocysts were spherical to ovoid in shape and measured 4-6μ).
The infection rate was 41. 94% (51. 06% in animals less than one month and 36.84% in calves more than one month to 4 months).
Cattle calves showing higher infection rate (frezion 47.37% & native 45.45%) than buffaloes calves 28.27%.
Males calves more susceptible than females to the infection with Cryptosporidiosis (Male 44.60% (33/ 74) - Female 38% (19/ 50).
The clinical examination of animals infected with the parasite revealed fever in some cases and presence of diarrhea of different degrees, the state of appetite varied according to the severity of infestation, tenesmus and general weakness. Faeces varied from pasty to watery in consistency yellow, pale yellow-to-yellow greenish in colour with mucous or blood.
Higher rate of infection was in non-hot months 44.62% than hot months 38.98%.
Concerning the hematological picture the present study revealed a significant decrease in hemoglobin, PCV and MCV while there was significant increase in MCHC and Erythrocytes and leukocytes recorded no significance variation between healthy and diarrheic cryptosporidium infected cattle calves. In buffaloes calves only leukocytes showing significant decrease. Differential leukocytes count showing significant increase in Neutrophil & Eosinophil while Monocytes and lymphocyte showing significant decrease.
So we can concluded that Cryptosporidial infection produced a variable effect on haematological picture in cattle calves, however in buffaloe calves it couldnot induce the same effect. These differences could be attributed to breed susceptibility to cryptosporidial infection. It was observed that buffaloe calves were more resistant to Cryptosporidial infection than cattle calves.
The bacteriological examination of 124 faecal swabs from diarrhoeic calves revealed 16(12.90%) bacterial cultures belonging to family Enterobacteriaceae. E. coli was the predominant bacterial infection among diarrhoeic cases. It was isolated from 15 cases with prevalence of 12.10%. Salmonella species was isolated from one faecal swab of diarrhoeic calves (0.88%).
