“…The prevalence of 12.32% for FIV and 5.80% for FeLV in Fortaleza-CE varied from the results found, through serological methods, in other cities of Brazil: 0.78% and 0.36% in São Paulo (Santos et al, 2013), 5.63% and 0.33% in Araçatuba-SP (Sobrinho et al, 2011) for FIV and FeLV, respectively, and 38.3% in Pelotas and Rio Grande-RS for FeLV (Meinerz et al, 2010). Felines with FIV and FeLV detected by PCR or nested PCR were 4.14% and 47.0% in Belo Horizonte (Teixeira et al, 2007;Coelho et al, 2011), respectively, and 15.70% for FIV in Pelotas -RS (Silva et al, 2014), and there was no presence of co-infection of these diseases in these studies. The discrepancy between the values found by the authors may reflect the methods used, since serological techniques show high specificity and sensitivity, with false negative results in cats regressively infected with FeLV and false positives for FIV due to the presence of maternal antibodies, especially in cats younger than six month-old (Hosie et al, 2009;Little et al, 2011).…”

“…Castration is a method that mainly reduces the vertical transmission mode (Levy et al, 2008). Most animals positive for FIV and FeLV were castrated (Jorge et al, 2011;Silva et al, 2014), contrary to a study carried out in 10 provinces of Canada (Little et al, 2009). Many of the clinic visits are from castrated animals, and many of these have not been tested prior to the surgical procedure and thus could be positive prior to castration.…”

“…The percentage of infected for FIV ranges from 3.2% to 15% and FeLV from 1% to 4% in populations of cats from various parts of the world (Gleich et al, 2009;Little et al, 2009;Westman et al, 2016). In some counties of Brazil, such as Belo Horizonte -MG, Rio Grande -RS, São Paulo -SP and Pelotas -RS, with prevalence ranging from 4.1% to 15.7% and from 6.2% to 38.3% of animals positive for FIV and FeLV have been reported, respectively, using serological techniques (direct and indirect immunofluorescence), PCR, or by nested PCR (Jorge et al, 2011;Lara et al, 2008;Meinerz et al, 2010;Silva et al, 2014;Teixeira et al, 2007).…”

Feline Immunodeficiency Virus (FIV) and Feline Leukemia Virus (FeLV) are important etiologic agents of immunosuppressive diseases in felines. The objective of the present study was to determine the prevalence of these retroviruses in domestic cats in Fortaleza, Ceará and the epidemiological factors associated with these infections. Between 2015 and 2016, 138 blood samples were collected and tested for FIV and FeLV by the enzyme immunoadsorption assay (ELISA). Parameters such as breed, gender, age, reproductive status, multi-cat environment, outdoor access and clinical manifestations were evaluated. The results showed that 12.32% were positive for FIV, 5.80% for FeLV and 1.45% for co-infection (FIV/FeLV). FIV+ animals were mostly mixed breed, neutered male adult cats, with indoor lifestyle and living in a multi-cat household. The most common clinical manifestation observed was disorders of the oral cavity. Factors found to increase the risk for FeLV seropositivity include mixed breed, young, spayed female cats, indoor lifestyle living in a multi-cat household were the most common epidemiological factors observed. The most common clinical manifestation was anorexia and apathy. The prevalence of these viruses were relatively high, compared with other region of Brazil. This study demonstrated that mixed breed, castrated, multi-cat environment and indoor lifestyle animals are of greater relevance for FIV and FeLV infection diseases. Factors related to cat demographics and health such as age, sex and type of household are important predictors for seropositive status to FeLV or FIV in Fortaleza. High prevalence of FeLV or FIV observed in our study is of concern, in view of the immunosuppressive potential of the two pathogens.

“…This explains the variations of seroprevalence from 2.5 to 31.3% for FIV and from 2.3 to 30.4% for FeLV that have been found in studies from different parts of the world (Arjona et al, 2000;Levy et al, 2006;Bande et al, 2012). In Brazil, the seroprevalence ranges from 5.6 to 16.7% for FIV and from 0.33 to 32.5% for FeLV (Teixeira et al, 2007;Macieira et al, 2008;Sobrinho et al, 2011) and, additionally, the infection rates found using molecular tests have ranged from 2 to 15.7% for FIV and from 0.5 to 47.5% for FeLV (Coelho et al, 2011;Marçola, 2011;Silva et al, 2014).…”

ABSTRACT. Our aims were to determine the frequencies of feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) in owned and stray cats in the northeastern region of Brazil, ascertain the status of FeLV infection, and investigate potential associated factors among the owned cats. Blood samples from 200 asymptomatic owned cats and 30 stray cats were processed using nested PCR and commercial immunochromatographic tests to diagnose infections. To evaluate the factors associated with FIV and/or FeLV in owned cats, a semistructured interview was conducted with each owner about the animal's environment, and these data were subjected to unconditional logistic regression. The frequencies for owned cats were 6% (12/200) and 3% (6/200) for FIV and FeLV, respectively. No owned cat was positive for both viruses. Stray cats showed frequencies of 6.66% (2/30) and 0% (0/30) for FIV and FeLV, respectively. Contact with other cats and living in peri-urban areas were considered to be risk factors (P < 0.05) for FIV. We did not identify any factors associated with infections with 2 L.C. Lacerda et al. Genetics and Molecular Research 16 (2): gmr16029633FeLV. Our results confirm the presence of these two retroviruses in the region under study. Our use of different diagnostic techniques allowed us to determine the frequency of retroviruses in the feline population more accurately, particularly with regard to infections by FeLV, which have complex pathogenesis.

“…No Brasil, pouco se conhece sobre a diversidade genética do FIV, porém já foi isolado e identificado o subtipo B (TEIXEIRA, 2010;SILVA et al, 2014), o qual apresenta baixa virulência (LARA et al, 2007).…”

RESUMOO gato doméstico (Felis catus) é um animal de companhia, com crescente valorização como pet, o que tem proporcionado o aumento de sua população nos domicílios brasileiros. Apresenta elevada importância na Saúde Pública, participando do ciclo de algumas zoonoses, dentre as quais a toxoplasmose. Constitui-se em um dos hospedeiros definitivos do Toxoplasma gondii, protozoário responsável por esta enfermidade. O gato doméstico também pode ser acometido pelo vírus da imunodeficiência felina (FIV) e devido à imunossupressão causada por tal patógeno pode vir a desenvolver doenças oportunistas. A infecção simultânea do T. gondii e o FIV pode predispor ao desenvolvimento agudo da toxoplasmose nos felídeos. Nesta revisão foram abordados aspectos etiológicos, epidemiológicos, clínicos, de diagnóstico e profiláticos destas duas enfermidades. Maior enfoque foi dado aos resultados encontrados no Brasil e no mundo relativos à frequência de anticorpos anti-T. gondii, à detecção de oocistos do T. gondii nas fezes destes animais, a dados sorológicos para o vírus da imunodeficiência felina em gatos domésticos, à coinfecção entre estes dois patógenos, além dos possíveis fatores associados às infecções. Tal abordagem buscou demonstrar o impacto das duas infecções na Medicina Veterinária e na Saúde Pública. PALAVRAS-CHAVE: AIDS felina, frequência, oocisto, toxoplasmose. Toxoplasma gondii INFECTION AND THE FELINE IMMUNODEFICIENCY VIRUS IN DOMESTIC CATS (Felis catus) -LITERATURE REVIEWABSTRACT The domestic cat (Felis catus) is a companion animal, with growing appreciation as a pet, which has provided the increase of its population in Brazilian households. It has high importance in Public Health, participating in the cycle of some zoonoses, among which toxoplasmosis. It is one of the definitive hosts of Toxoplasma gondii parasite responsible for this disease. The domestic cat can also be affected by feline immunodeficiency virus (FIV) and due to immunosuppression caused by this pathogen can go on to develop opportunistic infections. Simultaneous infection of T.
