Abstract (sommario):

Six cats developed malignant lymphoma 3 to 45 months after treatment for vaccine site-associated sarcoma. During the same time period, 184 cats were evaluated in the teaching hospital for vaccine site-associated sarcomas. Feline vaccine site-associated sarcoma is not believed to be associated with feline leukemia virus (FeLV) infection. Five of six cats were negative by enzyme-linked immunosorbent assay for FeLV antigens at the times of diagnosis of both sarcoma and lymphoma, and no cats were infected with feline immunodeficiency virus.

Abstract (sommario):

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.

Abstract (sommario):

Necropsies were performed on 630 adult cats in northern Florida to determine the prevalence and risk factors for heartworm infection in cats of this region. Heartworms were identified in 4.9% of cats, and serological evidence of heartworm exposure was present in 17% of cats. Not all cats from which heartworms were recovered were seropositive for heartworm antigen or antibody. There was no association between heartworm infection and co-infection with feline leukemia virus (FeLV) or feline immunodeficiency virus (FIV). Male cats were at higher risk of infection with heartworm, FeLV, or FIV than were females. Because even a single heartworm can cause clinical disease or death in cats, the authors conclude that cats in this region should receive heartworm prophylaxis to prevent heartworm infection.

Abstract (sommario):

AbstractPrior to the widespread use of vaccination for the control of feline immunodeficiency virus (FIV) infection, diagnosis was made by the detection of antibodies against FIV. A number of commercial animal side tests perform quite well for this determination, with positive predictive values between 91 and 100% and negative predictive values between 96 and 100%. Furthermore, results of these tests could be confirmed by western blot analysis of FIV test-positive sera. Currently, a killed whole virus FIV vaccine has been made available to practitioners. Vaccinated cats seroconvert by ELISA and western blot, making presently available diagnostic tests, which rely on antibody detection, useless in cats after vaccination. The advisory panels of the American Association of Feline Practitioners and Academy of Feline Medicine both recommend testing for feline leukemia virus antigen and FIV antibody before vaccination.

Abstract (sommario):

Abstract Studies were done on 53 cats with community-acquired infection with the feline immunodeficiency virus (FIV) to determine if hematologic abnormalities were comparable with those observed in patients seropositive for the human immunodeficiency virus (HIV). Nine cats were asymptomatic, 24 had clinical symptoms equivalent to AIDS-related complex (ARC), and 20 had AIDS-like disease. Hematologic abnormalities were detected in 75% (40 of 53) of FIV-seropositive cats, and multiple concurrent cytopenias were common. Anemia, lymphopenia, neutropenia, and thrombocytopenia occurred in 36%, 53%, 34%, and 8% of FIV- seropositive cats, respectively. Cytopenias were seen only in symptomatic (ARC or AIDS) cats. The occurrence of cytopenias and the distribution of clinical stages were similar in cats with concurrent feline leukemia virus (FeLV) infection and those with FIV alone, suggesting that these abnormalities were a direct consequence of FIV infection. In addition, abnormalities were noted in 72% of marrows from symptomatic cats and included hyperplasia of individual cell lineages and dysmorphic features. Our results demonstrate that the hematologic manifestations of FIV infection are strikingly similar to those reported in HIV-seropositive patients. Thus, FIV infection in cats is an excellent animal model to study the pathogenesis of blood and marrow abnormalities in AIDS, as well as to evaluate the hematologic toxicities of drug therapies.

Abstract (sommario):

Case records of 232 dogs and 29 cats with neutropenia were reviewed to examine the spectrum of underlying etiologies causing the neutropenia. Six etiological categories included nonbacterial infectious disease; increased demand due to marked inflammation, bacterial sepsis, or endotoxemia; drug-associated neutropenia; primary bone-marrow disease; immune-mediated neutropenia; and diseases of unclear etiology. The largest single category associated with the development of neutropenia was nonbacterial infectious disease (e.g., feline leukemia virus [FeLV], feline immunodeficiency virus [FIV], histoplasmosis, cryptococcosis, and parvovirus), with parvovirus infection accounting for 47.1% of all cases. The least common (0.38%) cause was naturally occurring immune-mediated neutropenia.

Dissertação de Mestrado Integrado em Medicina Veterinária
O vírus da Leucemia Felina (FeLV) e o vírus da Imunodeficiência Felina (FIV) pertencem à família Retroviridae. São responsáveis por duas viroses que ameaçam a vida e o bem-estar do gato doméstico, e a conservação de felinos silvestres como o lince da Península Ibérica. O principal objetivo deste estudo epidemiológico foi detetar a presença do FIV e do FeLV em gatos residentes na ilha de São Miguel, Açores. A amostra foi constituída por 90 gatos selecionados em grupos de risco elevado ou com sinais clínicos compatíveis com estas viroses, maioritariamente gatos errantes (84,4%) e assilvestrados (11,1%) que foram capturados para serem esterilizados e integrarem programas de adoção ou de restituição ao habitat. Através do teste ELISA, ViraCHECKFIV para pesquisa de anticorpos, obtivemos uma prevalência real de 14,2% de FIV na nossa amostra. Com o teste ELISA, ViraCHECKFeLV para pesquisa de antigénio, obtivemos uma prevalência real de 0,6% de FeLV na nossa amostra. Esta é a primeira publicação científica que demonstra a presença destes vírus na população felina da ilha de São Miguel. O perfil do gato infetado com FIV na amostra investigada é um gato macho, inteiro, de condição de vida livre, com um comportamento agressivo ou nervoso, com um ou mais linfonodos superficiais hipertrofiados e com gengivo-estomatite. A discussão dos resultados é feita à luz das frequências de infecção de FIV e de FeLV detetadas noutras ilhas do globo. Finalmente propõem-se medidas de controlo e de prevenção para mitigar a incidência de FIV e de FeLV e para delimitar a dispersão geográfica destas viroses na ilha de São Miguel.
ABSTRACT - EPIDEMIOLOGICAL STUDY OF FELINE IMMUNODEFICIENCY VIRUS AND FELINE LEUKEMIA VIRUS IN STRAY CATS AND FERAL CATS OF THE SÃO MIGUEL ISLAND, AZORES - The feline leukemia virus (FeLV) and the feline immunodeficiency virus (FIV) are two virus of the Retroviridae family. They are a major threat to the life and welfare of the domestic cat, and to the success of wildlife feline species conservation programs such as the Iberian lynx at the Iberian Peninsula. The main aim of this epidemiological study was to confirm the presence of FIV and FeLV in a sample of stray and feral cats of São Miguel Island in the archipelago of Azores. Ninety cats were sampled, mainly stray cats (84.4%) and feral cats (11.1%), during field operations of a trap, neuter and release or adoption program. The presence of FIV was confirmed by the ELISA test ViraCHECKFIV. The true prevalence obtained was 14.2%. The presence of FeLV was also confirmed by the ELISA test ViraCHECKFeLV. The true prevalence obtained was 0.6%. This is the first scientific communication of the presence of these viruses on the feline population of the island. The profile of the FIV infected cat is an intact male, free-roaming, with aggressive or nervous behavior, with one or more superficial lymph nodes hypertrophied and with signs of gingivostomatitis. The discussion is made by the light of the prevalence of FIV and FeLV reported on other islands in the world. Finally disease control and prevention measures are proposed to mitigate the incidence of FIV and FeLV and to restrict the geographical dispersion of these viruses in the island of São Miguel.

Of the 313 cats blood samples collected from Nov. 1993 to May 1996, 28(9.0%) and 3(1.0%) were positive for feline immuno- deficiency virus antibody and feline leukemia virus antigen respectively when tests with SNAP( Combo Enzyme-linked immuno- sorbent assay (IDEXX Company USA).FIV antibodies were also detected in 26 of 270 feline blood samples by indirect immuno- fluorescence antibody test (IFA) using glass slides with cells of Crandell feline kidney cells infected with FIV Petaluma strain. IFA result was detected by ELISA consistent with the ELISA test. No significant difference (P>0.05) in FIV antibody detected by ELISA were observed among the different sex groups, body weight groups and healthy status groups. However significant differences (P<0.05) were seen among the different source groups and the age groups, and highly significant differences (P<0.01) among the different breed groups and foraging territery (domain) groups of FIV infected cats. Erythrocytes count (RBC), hematocrit (PCV) and albumin/globulin ratio were significantly different(P<0.05) be- tween normal and antibody positive cats.No significant (P>0.05) were observed in other hematology and blood chemistry test results of normal and FIV infected cats.Clinical symptoms of the cat which died of FIV infection(the virus had been isolated) includes emaciation, anemia, bloody diarrhea,gingivitis and oral inflammation. Necropsy findings includes yellow coloration of the liver, spleen and kidney, right and left ventricular wall hyper- plasia, swollen mandibular lymph nodes,intestinal intussusception and several severe oral ulcers. Histopathologically amyloid were seen deposited in Disse space of liver and in renal glomeruli. Decreased number of lymphoid follicles with fewer lymphocytes were observed in the cortex of the mandibular lymph nodes and its medulla was filled with a large number of plasma cells.
