Reversible switch from hemoglobin A to C in sheep and recovery from anemia following experimental infection with Anaplasma ovis

Anemia causes a change in the type of circulating hemoglobin (Hb) in sheep carrying the βA-globin haplotype, where the Hb A is replaced with Hb C, unlike Hb B. The effect of the substitution of Hb A with Hb C on the recovery from anemia was investigated by comparing the hematological picture of sheep, following experimental infection with Anaplasma ovis.The blood values were obtained from 3 AB and 3 BB Hb sheep after the development of the disease where anemia is a pathognomonic symptom. The expression of the silent gene encoding for Hb C was detected by isoelectric focusing and quantified byhigh performance liquid chromatography Both Hb AB genotype and Hb C occurrence were involved in the lower recovery from anemia in the trial.
