Abstract

This study aimed to detect Mycoplasma spp. in naturally infected cats from Rio de Janeiro and to evaluate hematological abnormalities and factors associated with this infection. Out of the 197 cats sampled, 11.2% presented structures compatible with hemoplasma organisms on blood smears. In contrast, 22.8% were positive for Mycoplasma spp. by means of 16S rRNA gene real-time polymerase chain reaction, which reflects the weak concordance between techniques. The infection rates, by means of 16S rRNA gene conventional polymerase chain reaction, was 4.6%, 4.6% and 11.7% for Mycoplasma haemofelis (Mhf), 'Candidatus Mycoplasma turicensis' (CMt) and 'Candidatus Mycoplasma haemominutum' (CMhm), respectively. Mhf and CMhm infections are more frequent in the summer (p>0.05). Presence of anemia (p < 0.02), lymphocytosis (p < 0.03), thrombocytopenia (p < 0.04) and activated monocytes (p < 0.04) was associated with Mhf infection. No hematological abnormality was associated with CMt or CMhm infection. Male cats were more prone to be infected by Mhf or CMhm (p < 0.01). Adult cats had more chance to be infected by CMhm. Three hemoplasma species occur in the metropolitan region of Rio de Janeiro and Mhf seems to be the most pathogenic of them. Anemia is the most important hematological abnormality.
