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.

Ocorrência de micoplasmas hemotrópicos em caninos e felinos domésticos na região de Belém, PA

Hemotrophic mycoplasmas comprise a group of bacteria that can cause hemolytic anemia and several chronic diseases in animals. In cats three infecting species of hemoplasmas are reported: M. haemofelis, ‘Candidatus M. haemominutum’ and ‘Candidatus M. turicensis’, the first being considered the most pathogenic, whereas the dogs are normally infected by at least two mycoplasma species M. haemocanis and ‘Candidatus M. haematoparvum’. In order to assess the occurrence of hemotrophic mycoplasmas in feline and canine populations of Belém city were analyzed, by PCR, the genetic material from blood samples of 299 domiciled and stray animals. In 8.03% (24/299) of DNA samples of hemotrophic mycoplasmas was amplified, 1.78 % (3 /169) from infected dogs and 16.15% (21 /130) from infected cats. Among the cats the highest rates of infection were found in domiciled animals 22.86% (16/70) and in males 29.51% (18/61), the species ‘Candidatus M. haemominutum’ 8.46 % (11/130) get the higher incidence when compared to species Mycoplasma haemofelis 6.92 % (9/130). The infection in dogs was only identified among stray animals, with the ‘Candidatus M. haematoparvum’ being the only species identified with a rate of 1.78 % (3/169). It was possible to assess that hemotrophic mycoplasmas circulate in both species in the present report, domiciled felines and males formed the group at highest risk for infection and the agent ‘Candidatus M. haematoparvum’ seems to be the only one in circulation in the canine population.
