1. Serological and molecular investigation of Leishmania spp. infection in cats from an area endemic for canine and human leishmaniasis in Northeast Brazil
Resumo O objetivo do presente estudo foi investigar a ocorrência de anticorpos contra Leishmania spp., e sua associação com o vírus da imunodeficiência felina (FIV) e o vírus da leucemia felina (FeLV), em felinos domésticos provenientes de uma área endêmica no estado do Rio Grande do Norte, para a leishmaniose visceral canina e humana.

2. Oral lesions and retroviruses in shelter cats
RESUMO: As afecções orais são problemas comuns em medicina felina em diferentes locais do mundo e podem estar relacionadas a diferentes causas, como agentes infecciosos. Poucos estudos foram encontrados no Brasil sobre o levantamento das principais doenças orais e dos resultados de testes para retrovírus em gatos de abrigos, principalmente na região Su

3. Hemotrophic mycoplasmas as potential cause of anemia in domestic cats / Micoplasmas hemotrópicos como potenciais agentes causadores de anemia em felinos domésticos
The present study aimed to evaluate the magnitude of the hemotrophic mycoplasmas infections in anemic cats. Samples from 270 anemic cats (PCV≤29%) and 53 healthy cats were submitted to hematological analysis (CBC, cytologic evaluation of blood smear), serum biochemistry (total protein, albumin, alkaline phosphatase, alanine aminotransferase, aspartate ami

4. Hemoplasmas em gatos domésticos: Prevalência e sua associação à infecção natural pelos vírus das imunodeficiência e/ou leucemia felinas. / Hemoplasmas in domestic cats: Prevalence and its association to the Feline Immunodeficiency Virus and/or Feline Leukemia Virus natural infections.
As doenças infecto-contagiosas possuem uma alta morbidade entre os gatos domésticos e um diagnóstico impreciso ou retardado pode resultar no óbito do paciente. A associação entre infecções pelos vírus da imunodeficiência (FIV) e/ou leucemia (FeLV) felina com hemoplasmas possui grande importância na clínica médica, uma vez que os agentes podem ag

5. Frequência de leucemia e imunodeficiência viral felina em uma população hospitalar
Retroviruses make up a family of RNA virus that includes many agents of veterinary importance. The transcriptase reverse enzyme allows viral RNA to serve as template for production of a double-stranted DNA provirus. This provirus is then inserted in to the host?s genome. Two feline retroviruses have been identified that may cause immunodeficiency syndrome ?

6. Distinct subsets of retroviruses encode dUTPase.
The nonprimate lentiviruses feline immunodeficiency virus, equine infectious anemia virus, visna virus, and caprine encephalitis virus contain a gene segment in the polymerase gene that is lacking in the primate lentiviruses. A related sequence has been noted in other retroviruses, most notably the type D retroviruses. Computer searches have indicated a rela

7. Suppressive effect on polyclonal B-cell activation of a synthetic peptide homologous to a transmembrane component of oncogenic retroviruses.
Purified feline leukemia virus, UV light-inactivated feline leukemia virus, and a synthetic peptide (CKS-17) homologous to a well-conserved region of the transmembrane components of several human and animal retroviruses were each studied for their effects on IgG production by feline peripheral blood lymphocytes. Using a reverse hemolytic plaque assay, both t

8. CrFK Feline Kidney Cells Produce an RD114-Like Endogenous Virus That Can Package Murine Leukemia Virus-Based Vectors
The feline kidney cell line CrFK is used extensively for viral infectivity assays and for study of the biology of various retroviruses and derived vectors. We demonstrate the production of an endogenous, RD114-like, infectious retrovirus from CrFK cells. This virus also is shown to efficiently package Moloney murine leukemia virus vectors.

9. Posttranscriptional effector domains in the Rev proteins of feline immunodeficiency virus and equine infectious anemia virus.
By systematically dissecting the Rev proteins of feline immunodeficiency virus (FIV) and equine infectious anemia virus (EIAV), we have identified within each a short peptide that is functionally interchangeable with the effector domains found in Rev-like proteins from other retroviruses. The active sequences from FIV and EIAV differ in several respects from

10. Receptors and Entry Cofactors for Retroviruses Include Single and Multiple Transmembrane-Spanning Proteins as well as Newly Described Glycophosphatidylinositol-Anchored and Secreted Proteins
In the past few years, many retrovirus receptors, coreceptors, and cofactors have been identified. These molecules are important for some aspects of viral entry, although in some cases it remains to be determined whether they are required for binding or postbinding stages in entry, such as fusion. There are certain common features to the molecules that many

11. A Sodium-Dependent Neutral-Amino-Acid Transporter Mediates Infections of Feline and Baboon Endogenous Retroviruses and Simian Type D Retroviruses
The type D simian retroviruses cause immunosuppression in macaques and have been reported as a presumptive opportunistic infection in a patient with AIDS. Previous evidence based on viral interference has strongly suggested that the type D simian viruses share a common but unknown cell surface receptor with three type C viruses: feline endogenous virus (RD11

12. Primate and Feline Lentivirus Vector RNA Packaging and Propagation by Heterologous Lentivirus Virions
Development of safe and effective gene transfer systems is critical to the success of gene therapy protocols for human diseases. Currently, several primate lentivirus-based gene transfer systems, such as those based on human and simian immunodeficiency viruses (HIV/SIV), are being tested; however, their use in humans raises safety concerns, such as the gener
