The enzymes and electrolytes profiles in sera of Iranian stray dogs naturally infected with Neospora caninum
Treść / Zawartość
The protozoan Neospora caninum (Apicomplexa: Sarcocystidae), respectively infects canids and ruminants as the most definitive and intermediate hosts. A diagnosis of neosporosis is generally made on the basis of clinical signs together with the detection of high levels of antibodies in serum. The present study compares the serum electrolyte profile (Ca, K, Mg, Na, P) and serum enzyme level (ALP, AST, CPK) of non-infected dogs with those of stray dogs naturally infected with N. caninum. The indirect fluorescent antibody test (IFAT) revealed that 17 of the 137 analysed serum samples (12.41%) of the stray dogs were seropositive (Sp) to N. caninum. Serum levels of the electrolytes and the enzymes were evaluated in the 17 Sp and 28 seronegative (Sn, 20.44%) dogs using common enzyme kits, spectrophotometry and flame photometry techniques. The average serum level of ALP, AST, and CPK were found to be significantly higher in the Sp stray dogs. Measurements of the average serum levels of Ca, K, Mg, and P were higher in Sp than Sn stray dogs, with the average K level being significantly higher in seropositive stray dogs. It was concluded that evaluation of serum enzyme and electrolyte levels may be used to screen N. caninum infection in stray dogs.
