1. Morphofunctional analysis of the testis and spermatogenesis in adult African lions (Panthera leo, Linnaeus, 1758) / Análise morfofuncional do testículo e espermatogênese de leões africanos (Panthera leo, Linnaeus, 1758) adultos
The study of the testis morphology and the spermatogenetic process in wild animals is fundamentally important for the knowledge about the physiologic patterns by which the assisted reproduction protocols are established. The following objectives were proposed in this study: to describe the data of both testis morphometry and seminiferous tubule; to quantify

2. A lion lentivirus related to feline immunodeficiency virus: epidemiologic and phylogenetic aspects.
Feline immunodeficiency virus (FIV) is a novel lentivirus that is genetically homologous and functionally analogous to the human AIDS viruses, human immunodeficiency virus types 1 and 2. FIV causes immunosuppression in domestic cats by destroying the CD4 T-lymphocyte subsets in infected hosts. A serological survey of over 400 free-ranging African and Asian l

3. Patterns of Feline Immunodeficiency Virus Multiple Infection and Genome Divergence in a Free-Ranging Population of African Lions
Feline immunodeficiency virus (FIV) is a lentivirus that causes AIDS-like immunodeficiency disease in domestic cats. Free-ranging lions, Panthera leo, carry a chronic species-specific strain of FIV, FIV-Ple, which so far has not been convincingly connected with immune pathology or mortality. FIV-Ple, harboring the three distinct strains A, B, and C defined b

4. Mammalian mitogenomic relationships and the root of the eutherian tree
The strict orthology of mitochondrial (mt) coding sequences has promoted their use in phylogenetic analyses at different levels. Here we present the results of a mitogenomic study (i.e., analysis based on the set of protein-coding genes from complete mt genomes) of 60 mammalian species. This number includes 11 new mt genomes. The sampling comprises all but o

5. Worldwide prevalence of lentivirus infection in wild feline species: epidemiologic and phylogenetic aspects.
The natural occurrence of lentiviruses closely related to feline immunodeficiency virus (FIV) in nondomestic felid species is shown here to be worldwide. Cross-reactive antibodies to FIV were common in several free-ranging populations of large cats, including East African lions and cheetahs of the Serengeti ecosystem and in puma (also called cougar or mounta
