Haemotropic Mycoplasmosis in a Cat

Abstract

Feline hemotropic mycoplasmosis is a ricketsial disease that infects red blood cells and is caused by Mycoplasma haemofelis, Candidatus Mycoplasma haemominutum, and Candidatus Mycoplasma turicensis. An 8-month-old female domestic cat that had anorexia and weakness is the subject of this case study. Tachycardia, increased rectal body temperature, and icteric mucous membranes were found in clinical examination. Serum biochemistry evaluation revealed elevated activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) enyzme activities, as well as increased total and direct bilirubin concentrations.  Hematological evaluation showed anemia and leukocytosis characterized with lymphocytosis, monocytosis and neutropenia. Blood smear examination confirmed the presence of Mycoplasma haemofelis. After receiving oxytetracycline and methylprednisolone for 10 days, the clinical findings of the cat significantly improved. Feline hemotropic mycoplasmosis should be included in the differential diagnosis for cats presented with icterus, increased rectal body temperature and anemia.
