“…Given that the G2 cats were assessed independent of their clinical condition, it's plausible that the high frequency of mixed hemoplasma infection without clinical signs or hematological changes (as discussed further) can be related with longer exposure to hemoplasma species and no contribution of retroviruses. Therefore, hemoplasma infections detected by either PCR or cytology don´t necessarily indicate clinical disease (Macieira et al 2008) but points out the role of asymptomatic carrier cats as sources of transmission.…”

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.

“…So far, hemoplasmas have been reported in cats in the states of Paraná (DE MORAIS et al, 2007), Rio de Janeiro (MACIEIRA et al, 2008), São Paulo (BATISTA, 2004;HORA, 2008;DE BORTOLI et al, 2012), Rio Grande do Sul (SANTOS, 2008) and Maranhão (BRAGA et al, 2012). The prevalences of M. haemofelis, 'Candidatus M. haemominutum' and 'Candidatus M. turicensis' were 2.2%, 6.7% and 0.5%, respectively.…”

“…In Brazil, the prevalences of hemoplasmas among healthy and anemic cats have been found to range from 2.1% to 38% for M. haemofelis; 4% to 13.5% for 'Candidatus M. haemominutum'; and 0.37% to 2.7% for 'Candidatus M. turicensis' (BATISTA, 2004;MACIEIRA et al, 2008;HORA, 2008;SANTOS et al, 2009;BRAGA et al, 2012;DE BORTOLI et al, 2012). DNA from Bartonella henselae and B. clarridgeiae was detected in three and one out of the 178 cats sampled (1.7%), respectively.…”

Hemotrophic mycoplasmas (hemoplasmas), Bartonella sp., Hepatozoon sp. and Cytauxzoon felis are prominent pathogens that circulate between cats and invertebrate hosts. The present study aimed to detect the presence of DNA from hemoplasmas, Bartonella sp., Hepatozoon sp. and Cytauxzoon felis, and then confirm it by means of sequencing, in blood samples from cats in Cuiabá, MT, Brazil. From February 2009 to February 2011, blood samples with added EDTA were collected from 163 cats that were being housed in four different animal shelters in the city of Cuiabá, state of Mato Grosso, Brazil and from 15 cats that were admitted to the veterinary hospital of the Federal University of Mato Grosso (UFMT). Out of the 178 cats sampled, 15 (8.4%) were positive for hemoplasmas: four (2.2%) for Mycoplasma haemofelis, 12 (6.7%) for 'Candidatus M. haemominutum' and one (0.5%) for 'Candidatus M. turicensis'. One cat (0.5%), a patient that was attended at the veterinary hospital, was coinfected with M. haemofelis, 'Candidatus M. haemominutum' and 'Candidatus M. turicensis', based on sequencing confirmation. Four cats were positive for Bartonella spp.: three (1.7%) for B. henselae and one (0.5%) for B. clarridgeiae. None of the animals showed Cytauxzoon sp. or Hepatozoon sp. DNA in their blood samples. This study showed that cats housed in animal shelters in the city of Cuiabá, state of Mato Grosso, are exposed to hemoplasmas and Bartonella species.

“…In fact, disease manifestations in animals are most frequently reported in special cases, for example in association with drugs or retrovirus-induced immunosuppression, poor nutrition, pregnancy, lactation and other concomitant diseases (MACIEIRA et al, 2008).…”

Hemotropic mycoplasmas in dogs, such as Mycoplasma haemocanis, have been described worldwide. Recently, these pathogens have been reported to be causative agent of zoonosis. It is known that its transmission may occur through the action of blood-sucking arthropods (e.g. ticks or fleas), through blood transfusion, contaminated fomites and/or transplacentally. In Brazil, M. haemocanis is present in practically all regions and the tick Rhipicephalus sanguineus sensu lato is suspected the main vector. In the municipality of Campo Grande, state of Mato Grosso do Sul, there is little information about infection of dogs by M. haemocanis, or on the main epidemiological features associated with it. Thus, the aim of the present study was to determine the occurrence of M. haemocanis among dogs infested by ticks and to assess possible associations with some epidemiological factors. The polymerase chain reaction (PCR) and DNA sequencing were used to analyze dog blood samples (n = 94). DNA from M. haemocanis was detected in four samples. No significant associations were observed with any epidemiological parameter analyzed here. However, the results from this study confirm that this pathogen is circulating in this region and should be considered in the differential diagnosis of diseases among anemic dogs.
