Three hemoplasma species are recognized in domestic cats: Mycoplasma haemofelis, 'Candidatus Mycoplasma haemominutum' and 'Candidatus Mycoplasma turicensis'. We report the prevalence and hematological abnormalities of hemoplasma infection in 369 domestic cats from three different populations (blood donors, hospitalized cats and shelter cats) from Southern Brazil. Complete blood counts were performed at the time of blood collection, and DNA was extracted and tested by conventional PCR for each hemoplasma species. A total of 79 samples (21.40%) were positive for at least one species. The most prevalent hemoplasma was 'Candidatus Mycoplasma haemominutum', with 50/369 (13.55%) positive cats, followed by 'Candidatus Mycoplasma turicensis', 10/369 (2.71%), and Mycoplasma haemofelis, 8/369 (2.16%). Mycoplasma haemofelis and 'Candidatus Mycoplasma haemominutum' coinfection was observed in 4/369 (1.08%), whereas 'Candidatus Mycoplasma haemominutum' and 'Candidatus Mycoplasma turicensis' in 5/369 (1.35%). Three cats (0.81%) were infected with all three hemoplasmas. There was no association between infection and the different populations. Anemia was associated with Mycoplasma haemofelis and 'Candidatus Mycoplasma haemominutum', but not with 'Candidatus Mycoplasma turicensis'. Male cats and cats with outdoor access were more likely to be infected. Although 'Candidatus Mycoplasma haemominutum' is believed to cause minimal or no hematological alterations, the infected cats studied herein were more likely to be anemic.
溶血支原体、“溶血微小支原体暂定种”和“图尔库支原体暂定种”。我们报告了巴西南部三个不同群体（献血猫、住院猫和收容所猫）的369只家猫血支原体感染的患病率和血液学异常情况。采血时进行全血细胞计数，并提取DNA，通过常规聚合酶链反应对每种血支原体进行检测。共有79份样本（21.40%）至少对一种血支原体呈阳性。最常见的血支原体是“溶血微小支原体暂定种”，有50/369（13.55%）只猫呈阳性，其次是“图尔库支原体暂定种”，10/369（2.71%），溶血支原体为8/369（2.16%）。在4/369（1.08%）的猫中观察到溶血支原体和“溶血微小支原体暂定种”的合并感染，而在5/369（1.35%）的猫中观察到“溶血微小支原体暂定种”和“图尔库支原体暂定种”的合并感染。三只猫（0.81%）感染了所有三种血支原体。感染与不同群体之间没有关联。贫血与溶血支原体和“溶血微小支原体暂定种”有关，但与“图尔库支原体暂定种”无关。雄性猫和有户外活动机会的猫更容易被感染。尽管“溶血微小支原体暂定种”被认为引起的血液学改变最小或没有，但本文研究的感染猫更易患贫血。
