“…A associação entre anemia e infecção por esses hemoplasmas é controversa (Kewish et al 2004, Ishak et al 2007, Bauer et al 2008, pois diferente do observado na infecção por M. haemofelis, a infecção por 'Candidatus M. haemominutum' tende a um quadro subclínico (Foley et al 1998, Sykes 2010. Segundo Tasker (2010), em gatos naturalmente infectados por 'Candidatus M. turicensis', apenas os que apresentam coinfecção por M. haemofelis ou 'Candidatus M. haemominutum' tendem a apresentar valores de volume globular significativamente menores quando comparados a gatos sadios.…”

Pesq. Vet. Bras. 33(9):1116-1120 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.

“…However, high prevalences of the latter two species have occasionally been reported, such as in a South African study with Candidatus M. turicensis (24), and in a Canadian study with M. haemofelis (18). The prevalence among domestic cats around the world ranged from 0.4% to 35% for Candidatus M. haemominutum, from 0.3% to 6.5% for Candidatus M. turicensis, from 0.125% to 10% to Mycoplasma haemofelis , and from 0 to 0.7% for Candidatus M. haematoparvum-like (1, 2, 10, 13, 14, 16, 17, 18, 19, 20, 22, 23, 24, 26, 27, 28, 31, 36, 38, 39, 41, 45). …”

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.

“…Candidatus Mycoplasma haemominutum and Candidatus Mycoplasma turicensis can lead to hematological alterations during co-infections with others hemoplasma species or retroviruses. Cats with ready access to streets and high exposure to disease vectors have increased risk of becoming infected with hemotropic mycoplasmas (Ishak et al 2007). since hemoplasmas haven't been successfully cultivated in vitro to date, the diagnosis of the infection was mainly based on cytological identification of organisms on the surface of red blood cells.…”

ABSTRACT.-Firmino F.P., Aquino L.C., Marçola T.G., Bittencourt M.V., Mycoplasma haemofelis is the agent of feline infectious anemia, although Candidatus M. haemominutum can also be associated. This study evaluated the frequency and hematological alterations caused by hemoplasma infections and co-infections with FeLV, FIV and Toxoplasma gondii in domestic cats from two distinct areas (urban -G1 and periurban -G2) of Brasília, Brazil. One hundred cats were evaluated, 51 from the G1 area and 49 from G2. No cats were positive for T. gondii. Hemoplasma infection was diagnosed in 33% cats from G1 and 32.6% from G2 (p>0.05). In G1 35.3% of the positive cats were infected with Mycoplasma haemofelis, 47.06% with Candidatus Mycoplasma haemominutum and 17.64% with mixed hemoplasma species infection; 12.5% of the cats identified as PCR positive in G2 were infected with Mycoplasma haemofelis, 18.75% with Candidatus Mycoplasma haemominutum and 68.75% with mixed infection. Cats from the periurban area had higher mixed hemoplasmas infection rates than those from urban area, and most of them were asymptomatic carriers. Cytology results were positive in only 5% of cats from G1. Mycoplasma haemofelis infected cats had normocytic normochromic anemia while the cats infected with Candidatus Mycoplasma haemominutum or with both species did not. 37.2% of G1 cats were co-infected with Mycoplasma haemofelis and FeLV, and presented lower PCV and hemoglobin concentration than those infected only with Mycoplasma haemofelis. The co--infection with Candidatus Mycoplasma haemominutum and FeLV produced lower WBC, segmented cells and platelets, and increased total protein concentration.
