13. Estudo epidemiológico de doenças infecciosas em anatídeos da Fundação Parque Zoológico de São Paulo / Epidemiological study of infectious diseases on waterfowls from Fundação Parque Zoológico de São Paulo
Waterfowls housed in ponds of zoos and parks are under constant risk of exposure to pathogens of migratory birds that visit these places every year. Some of them involving zoo animals and humans. The spread of particular diseases may also become a serious threat for domestic poultry. So, surveillance, focused in early detection of some diseases, can be an in

14. Prevalência de anticorpos contra Chlamydophila spp em ovinos de propriedades localizadas na região de Londrina, Paraná
As Bactérias da família Chlamydiaceae são classificadas nos gêneros Chlamydia e Chlamydophila. O primeiro contêm as espécies C. trachomatis, C. suis e C. muridarum e o segundo as espécies C. abortus, C. pecorum, C. psittaci, C. felis, C. pneumoniae e C. caviae. Entre as espécies do gênero Chlamydophila causadoras de doença da esfera reprodutiva em

15. Diagnóstico molecular e sorológico de Chlamydophila spp em amostras biológicas de animais experimentalmente e naturalmente infectados
Chlamydophila abortus (anteriormente classificada como Chlamydia psittaci sorotipo 1) tem sido descrita em muitos países, associada principalmente com distúrbios reprodutivos em ovinos, bovinos e caprinos. A detecção de C. abortus é usualmente realizada por métodos sorológicos (fixação de complemento, ELISA) e de cultivo em células de linhagens ou

16. Chlamydophila abortus em animais de produção
A Chlamydophila abortus (anteriormente classificada como Chlamydia psittaci sorotipo 1) tem sido descrita em muitos países, associada principalmente com distúrbios reprodutivos em ovinos, bovinos e caprinos. O aborto enzoótico dos ovinos e caprinos e o aborto epizoótico dos bovinos são as doenças mais importantes causadas por esta bactéria. No Brasil,

17. Chlamydophila abortus in a Brown Skua (Catharacta antarctica lonnbergi) from a Subantarctic Island
On Bird Island, South Georgia, a new strain of Chlamydophila abortus was detected in one Brown skua out of 37 specimens from six different seabird species. Phylogenetic analysis of the rnpB and omp1 genes indicated the strain to be more closely related to C. abortus than to 6BC, the type strain of Chlamydophila psittaci.

18. Polymorphonuclear Neutrophils Are Necessary for the Recruitment of CD8+ T Cells in the Liver in a Pregnant Mouse Model of Chlamydophila abortus (Chlamydia psittaci Serotype 1) Infection
The role of polymorphonuclear neutrophils (PMNs) in the development of the specific immune response against Chlamydophila abortus (Chlamydia psittaci serotype 1) infection was studied in a pregnant mouse model involving treatment with RB6-8C5 monoclonal antibody. PMN depletion significantly affected the immune response in the liver, in which the T-lymphocyte

19. Newly Characterized Species-Specific Immunogenic Chlamydophila pneumoniae Peptide Reactive with Murine Monoclonal and Human Serum Antibodies
A monoclonal antibody (MAb) directed against an unknown Chlamydophila pneumoniae epitope has been characterized, and the respective peptide mimotope has been identified. A murine MAb specific for C. pneumoniae was used to select peptides from phage display libraries. The peptides identified from the phage display library clones reacted specifically with the

20. Antigenic Organization of the N-Terminal Part of the Polymorphic Outer Membrane Proteins 90, 91A, and 91B of Chlamydophila abortus
A series of overlapping recombinant antigens, 61 to 74 residues in length, representing polymorphic outer membrane protein 90 (POMP90) of Chlamydophila abortus and two recombinant peptides spanning gene fragment p91Bf99 of POMP91B were assessed by immunoblotting to determine the antigen-binding sites of 20 monoclonal antibodies to POMP90, -91A, and -91B.

21. Genome sequence of Chlamydophila caviae (Chlamydia psittaci GPIC): examining the role of niche-specific genes in the evolution of the Chlamydiaceae
The genome of Chlamydophila caviae (formerly Chlamydia psittaci, GPIC isolate) (1 173 390 nt with a plasmid of 7966 nt) was determined, representing the fourth species with a complete genome sequence from the Chlamydiaceae family of obligate intracellular bacterial pathogens. Of 1009 annotated genes, 798 were conserved in all three other completed Chlamydiac

22. Interaction between Components of the Type III Secretion System of Chlamydiaceae
Members of the family Chlamydiaceae possess at least 13 genes, distributed throughout the chromosome, that are homologous with genes of known type III secretion systems (TTS). The aim of this study was to use putative TTS proteins of Chlamydophila pneumoniae, whose equivalents in other bacterial TTS function as chaperones, to identify interactions between ch

23. Identification of Protective Epitopes by Sequencing of the Major Outer Membrane Protein Gene of a Variant Strain of Chlamydia psittaci Serotype 1 (Chlamydophila abortus)
Protective monoclonal antibodies (MAbs) to the major outer membrane protein (MOMP) of species of the family Chlamydiaceae, which is the primary vaccine candidate antigen, recognize nonlinear epitopes conferred by the oligomeric conformation of the molecule. Protective MAbs failed to recognize oligomeric MOMP of the variant strain LLG, which bears amino acid

24. B-Cell-Deficient Mice Show an Exacerbated Inflammatory Response in a Model of Chlamydophila abortus Infection
The resolution of Chlamydophila abortus (Chlamydia psittaci serotype 1) infection is dependent on gamma interferon and CD8+ T cells, and classically, B cells have been considered to play a minimal role in host defense. The role of B cells in the immune response was studied by using a model of infection in mice with genetically modified immunoglobulin M trans
