This study aims to determine serum amyloid A (SAA), haptoglobin (Hp), interleukin-1β (IL-1β), interleukin 6 (IL-6) and tumor necrosis factor-α (TNF-α) concentration in cases of Cryptosporidiosis that are frequently encountered in calves in veterinary medicine. Although many experimental studies have been conducted in this field, studies of naturally infected calves are quite a few. In this study, 10 neonatal Holstein calves diagnosed with Cryptosporidium were included. Stool samples were taken from calves with diarrhea using a rapid test kit (BIO-K 313 rapid test kit). Blood samples were obtained from the jugular vein pre- and post-treatment for biochemical measurements. SAA, Hp, IL-1β, IL-6 and TNF-α concentration measurements were conducted with ELISA reader using commercial kits. Calves with Cryptosporidiosis presenting with diarrhea showed a statistical difference in SAA, Hp, IL-1β, IL-6, white blood cell and hemoglobin values before and after treatment, whereas hematocrit, red blood cell and TNF-α concentrations did not show any statistical difference before and after treatment. According to these findings, to follow up the treatment process of calves with Cryptosporidiosis, it is thought that measuring the concentration of SAA, Hp, IL-1β and IL-6 will be useful for determining disease severity, selecting appropriate treatment, following treatment efficacy and determining subclinical diseases.
