Hemoplasmas are bacteria that infect erythrocytes, attaching to the red blood cell. There is a need for more reports of hemoplasma infection prevalence and molecular characterization among cats in Brazil since there are only few published reports. The present work aimed to detect and molecularly characterize the presence of hemotrophic mycoplasmas in domestic cats with outdoor access from São Luís, Maranhão, Brazil. Twenty cats (10%) were positive for Candidatus M. haemominutum, five (2.5%) for M. haemofelis, and four (2.%) for M. turicensis based on 16S rRNA gene PCRs. Five cats (2.5%) were co-positive for Candidatus M. haemominutum and M. haemofelis. PCR diagnosis was confirmed by sequencing; and phylogenetic analysis was based on 16S rRNA and rnpb genes.
血巴尔通体是一类感染红细胞的细菌,附着在红细胞上。在巴西,由于仅有少数文献报道,因此有必要对猫的血巴尔通体感染流行率和分子特征进行更多的研究。本研究旨在检测和分子鉴定来自巴西圣路易斯市(马腊尼昂州)户外饲养的家猫中是否存在血巴尔通体。20 只猫(10%)的 16S rRNA 基因 PCR 检测呈 Candidatus M. haemominutum 阳性,5 只(2.5%)呈 M. haemofelis 阳性,4 只(2.0%)呈 M. turicensis 阳性。5 只猫(2.5%)同时呈 Candidatus M. haemominutum 和 M. haemofelis 阳性。PCR 诊断通过测序进行确认;基于 16S rRNA 和 rnpb 基因进行了系统发育分析。
