“…Unlike our results, feline hemoplasma infection has reported to be correlated with male gender, non-pedigree status and access to the outdoors (SYKES et al, 2008;WILLI et al, 2006a, b;TASKER et al, 2003;GRINDEM et al, 1990;LURIA et al, 2004). Some studies (NASH;BOBADE, 1986;GRINDEM et al, 1990;HARRUS et al, 2002;MACIEIRA et al, 2008;SYKES et al, 2008;GENTILINI et al, 2009) but not others (WILLI et al, 2006a;DE BORTOLI et al, 2012) have shown an association between retrovirus infection and hemoplasmosis.…”

Hemoplasmas are bacteria living in feline red blood cells. Feline hemoplasmosis is frequently associated with old male cats that have access to the streets. This study aimed to detect the presence of hemoplasma speciess in domiciled and free-roaming cats in Campo Grande, state of Mato Grosso do Sul (MS), Brazil, using molecular techniques. Between January 2013 and April 2013, EDTA-whole blood samples were collected from 151 domestic cats (65 free-roaming and 86 domiciled cats). Samples were subjected to PCR assays targeting hemoplasmas 16S rRNA, followed by sequencing, BLAST analysis and phylogenetic analysis. Results show an occurrence of 36.4% for hemoplasmas. Twenty-three cats (15.2%) were positive for 'Candidatus Mycoplasma haemominutum', 17 (11.2%) for M. haemofelis and 15 (9.9%) for 'Candidatus M. turicensis', from PCR. Coinfection by two or three hemoplasmas was found in 25 cats (16.6%). No statistically significant difference between genders or between lifestyles was observed for the presence of hemoplasmas among the cats. Results show different hemoplasma species are present in cat population (Campo Grande, MS, Brazil). It is suggested that a differential diagnosis for feline hemoplasmosis should be made when cats show nonspecific clinical signs of disease with systemic manifestation.

“…Sendo assim, o protocolo para reação de PCR, em uma única etapa de reação, avaliado neste trabalho, foi eϐicaz e especíϐico para o diagnóstico de E. canis na espécie felina. Vale ressaltar que a parasitemia nesta espécie é bem menor que em cães, (Luria et al 2004;Lappin et al 2005, Shaw et al 2005, Eberhardt et al 2006) sendo imprescindível estabelecer o limiar de detecção das espécies erliquiais no sangue de felinos pelas técnicas de PCR em etapa única.…”

“…Também é possível que os gatos deste estudo possuam menor número de cópias circulantes de DNA de Ehrlichia spp. que os cães, ou ainda, que a alíquo-ta da amostra coletada não tivesse a presença de mórulas, gerando resultados falso-negativos (Luria et al 2004, Lappin et al 2005, Eberhardt et al 2006). Segundo Shaw et al (2005), felinos parecem ser menos predispostos que cães a certas doenças transmitidas por carrapatos, tais como erliquiose, babesiose e hepatozoonose e também questiona a possibilidade dos felinos apresentarem uma resistência inata ou adaptativa à infecção que limita o desenvolvimento da doença ou de certa forma, comprometem a transmissão de agentes pelos carrapatos.…”

ABSTRACT.-Corrêa E.S., Paludo G.R., Scalon M.C., Machado J.A., Lima A.C.Q., Pinto A. Ehrlichia sp. and Anaplasma platys are Gram-negative micro-organisms, obligate intracellular parasites, residing in cytoplasmic vacuoles of leukocytes and platelets, found in peripheral blood or tissue. Few reports have been made about ehrlichiosis and anaplasmosis in cats in Brazil, which are based on the presence of morulae in leukocytes and platelets, or by detecting antibodies. The objective of this study was to investigate the natural infection with Ehrlichia sp. and A. platys in cats in Campos dos Goytacazes-RJ, by hematoscopia and DNA detection of these agents. Samples of whole blood and serum from 91 cats, regardless of race, gender and age. Blood count, serum biochemistry and PCR using primers for Ehrlichia sp. and A. platys were perfomed. Data from hematoscopia showed 9.89% of morulae only in platelets. The DNA of A. platys was detected in 13.18% of the 91 samples and 44.44% of the positive at hematoscopia. The DNA of Ehrlichia sp. was not detected in any sample. All animals studied did not show clinical signs neither positive laboratory results. The data suggest that domestic cats can serve as potential reservoirs for A. platys as asymptomatic form of related diseases.

“…Feral cats 6,7 or endangered wild felids as linx and panthers 8 are also under risk of FeLV infection. Both retroviruses affect the immune system and are causes of significant morbidity and mortality 9 or predispose to infections such as hemotropic mycoplasmas 10 or feline infectious peritonitis 11 .…”

The aim of this study was to identify risk factors for feline leukemia virus (FeLV) infection in cats (n = 812) from the city of São Paulo. Information on age, gender, outdoor access, reproductive status, origin and number of potential contacts were obtained for each animal. Direct immunofluorescence test was used to identify the infected cats. Fifty cats (6.2 %) were positive for FeLV infection. The risk factors identified were "outdoor access" (OR = 47.2; p < 0.001), "having been rescued from the street" (OR = 3.221; p = 0.008) or being three to six year old (OR = 3.046; p = 0.009); the most important risk factor was free outdoor access. A predictive model for FeLV infection was built based on the results of the multivariate analysis. Cats with free outdoor access are more predisposed to infection, with 18% more chances of becoming infected. If the animal is one to three year old, the probability increases, reaching 34%. If the cat is exposed to these three risk factors, the probability of infection is even higher (63%). When analyzed together or as isolated risk factors, the age and being rescued from the street represent less impact on the spreading of the FeLV, as the probability of infection for cats exposed to each of these risk factors is 1 and 4%, respectively. Thus, free roaming and outdoor access are the most important risk factors associated to FeLV infection among cats in São Paulo city and must be taken in consideration in the prevention of this retrovirus infection.

ResumoO objetivo deste estudo foi o de identificar os fatores de risco para a leucemia viral felina (FeLV) em uma amostragem de 812 gatos da cidade de São Paulo, Brasil. Informações sobre idade, sexo, acesso à rua, estado reprodutivo, origem e número de contactantes foram obtidos para cada animal. Teste de imunofluorescência direto para a pesquisa de antígeno viral em esfregaço de sangue periférico foi utilizado para a identificação dos felinos infectados. Foram encontrados 51 gatos (6,2%) positivos para a infecção. Os fatores de risco identificados foram "acesso a rua" (OR = 47,2; p < 0,001), "ter sido resgatado da rua" (OR = 3,221; p = 0,008) e "ter idade entre 3 e 6 anos" (OR = 3,046; p = 0,009), sendo o "livre acesso à rua" o fator de risco mais importante. Foi elaborado um modelo preditivo para a infecção pelo FeLV, baseandose nos resultados da análise multivariada. Gatos com acesso livre à rua apresentam 18% mais chances de se infectarem e se estiverem na faixa etária entre 3 e 6 anos de idade o risco aumenta para 34%. Se o gato estiver exposto aos três fatores de risco, a probabilidade de infecção é ainda mais alta, de 63%. Quando analisados em conjunto ou como fatores de risco isolados, a idade e o fato de "ter sido resgatado da rua" possuem menor impacto na disseminação de FeLV, já que a probabilidade de infecção para os gatos expostos a cada um desses fatores é de 1% e de 4%, respectivamente. Assim, o acesso livre a rua e ter sido resgatado da rua...
