Mycoplasma haemofelis, ‘Candidatus Mycoplasma haemominutum’ and ‘Candidatus Mycoplasma turicensis’ are the causative agent of the feline mycoplasmosis, which could cause acute or chronic anemia. The aim of this work was to determine the occurrence of hemoplamas in domestic cats from Belém, Pará. To this, 201 cats were divided into three groups: Group A were composed by 101 stray cats captured by Zoonosis Control Center, group B were composed by 62 owners healthy cats and group C were composed by 38 owners cats that were suffering by some medical condition. Blood samples were collected to perform Polymerase Chain Reaction (PCR) to detect the DNA of these agents, which were sequenced and aligned. Statistical analysis was performed to detect association between the infection, the sex of the animals and experimental groups. The DNA of at least one of the hemoplasmas studied were detected in 19,9% (40/201) of the samples, being the DNA of ‘Candidatus M. haemominutum’ was found in 7.96% (16/201) of samples, M. haemofelis in 1.49% (3/201) of samples, while ‘Candidatus M. turicensis’ in 12.93% (26/201) of the samples. The DNA of these three agents was detected in cats from groups A and C, while in Group B was detected only ‘Candidatus M. turicensis’ and ‘Candidatus M. haemominutum’. The influence of sex on hemoplasma infection was detected only between ‘Candidatus M. haemominutum’ and males. These findings showed that hemoplasma circulate among domestic cats in Belém, and ‘Candidatus M. turicensis’ and ‘Candidatus M. haemominutum’ were more common than M. haemofelis, especially in stray cats. |
