Hemotropic mycoplasma in cats — A comment

Viroj Wiwanitkit, Professor

Dear Sir,

I read the recent publication by Nibblett et al (1) with a great interest. Nibblett et al (1) retrospectively summarized on anemic cats diagnosed with hemotropic mycoplasma (HM) and concluded that the cats with positive retroviral status, concurrent illness, or lack of erythroid regeneration were most likely to die (2). There are some concerns about this report. First, the retrospective medical record review has its limitation in reliability of data. Second, Nibblett et al (1) could not rule out the possible co-etiology of anemia in the cat with mycoplasma anemia. Third, the classification of the species inducing the pathology was not completely reported. Indeed, the third newly identified species was not detectable by simple laboratory method but requires molecular diagnostic methods (2).
