However, there is a limited data on the prevalence of these organisms in Iranian cats.  Methods:    We investigated the presence of feline haemotropic mycoplasma and probable risk factors for these infections among 60 ectoparasite-infested stray cats in southeast of Iran using PCR assay.  Results:     The overall prevalence of haemotropic mycoplasma was estimated 18.3%. Pallor mucous membrane, anorexia, weight loss and splenomegaly were the most common signs and the infection rate was significantly higher in symptomatic cats in comparison with apparently healthy ones (P = 0.001). Age, gender and hematological alterations were not significantly associated with infection status while the level of BUN, creatinine, total protein and globulin were significantly higher among infected animals. Conclusion:    The prevalence of feline hemoplasma infection in stray cats seems to be considerable in our study. More investigations are needed to obtain further information on epidemiological aspects of hemoplasmas in cats in Iran. https://jmb.tums.ac.ir/index.php/jmb/article/view/249 https://jmb.tums.ac.ir/index.php/jmb/article/download/249/183
