13. Ocorrência de hemoparasitos e ectoparasitos em veado-catingueiro (Mazama gouzoubira Fischer, 1814), veado-campeiro (Ozotocerus bezoarticus Linnaeus, 1758) e cervo-do-pantanal (Blastocerus dichotomus Illiger, 1815): utilização de métodos parasitológicos e moleculares
Os cervídeos são ruminantes selvagens que estão em contato com os ruminantes domésticos em várias regiões do Brasil, facilitando, assim, o trânsito de patógenos entre os dois grupos. Esse grupo de ruminantes possui espécies ameaçadas de extinção. Em relação aos animais de cativeiro, o trânsito de animais entre zoológicos ou criatórios favore

14. Cultivo in vitro de Anaplasma marginale e A. phagocytophilum em células de carrapatos: uma revisão
Linhagens contínuas de células já foram estabelecidas a partir de várias espécies de carrapatos ixodídeos e argasídeos e representam uma ferramenta excelente para o isolamento e propagação de patógenos, permitindo a produção de material antigênico para testes diagnósticos, produção de anticorpos e vacinas, e também para estudos das relaçõe

15. Exposição de felídeos selvagens a agentes infecciosos selecionados / Exposure of wild felids to selected infectious agents
Este estudo avaliou a exposição de 12 espécies de felídeos selvagens de vida livre (n=22) e mantidas em cativeiro (n=210) no Brasil a 16 agentes potencialmente patogênicos para membros da família Felidae, como herpesvírus felino 1 (FHV 1), calicivírus felino (FCV), parvovírus felino (FPV), coronavírus felino (FCoV), vírus da leucemia felina (FeLV)

16. Prevalência e análise molecular de Anaplasma platys em cães da Venezuela
Amostras de sangue coletadas de cães clinicamente sadios pertencentes ao exército da Venezuela e de seus treinadores foram analisadas pela técnica de PCR 16S rRNA específica para Anaplasma platys, A. phagocytophilum ou Ehrlichia ewingii. Dezesseis por cento (7/43) dos cães foram positivos, enquanto que todas as amostras de origem humana [25] foram negat

17. Analysis of Genetic Identity of North American Anaplasma phagocytophilum Strains by Pulsed-Field Gel Electrophoresis
Biological and geographic heterogeneity of anthropozoonosis caused by Anaplasma phagocytophilum is poorly understood. Seven North American A. phagocytophilum strains were compared by PFGE. The average genome size was 1.58 Mbp, and restriction patterns were identical. New World strains of A. phagocytophilum have a large genome and a high degree of genetic uni

18. Molecular Evidence of Anaplasma phagocytophilum in Ixodes ricinus Ticks and Wild Animals in Austria
Real-time PCR analysis of a groESL heat shock operon segment showed the presence of two genetic lineages of Anaplasma phagocytophilum in Ixodes ricinus ticks as well as one variant in wild red and roe deer, the latter supposedly representing the natural reservoir of one variant of A. phagocytophilum.

19. Defective Phagocytosis in Anaplasma phagocytophilum- Infected Neutrophils
Anaplasma phagocytophilum infection induces functional neutrophil changes. Using both Candida albicans and fluorescent-aggregate phagocytosis assays, we examined whether neutrophil and dimethyl sulfoxide-differentiated HL-60 cell infection impairs internalization. A. phagocytophilum infection significantly decreased phagocytosis compared to that of controls

20. Anaplasma phagocytophilum Has a Functional msp2 Gene That Is Distinct from p44
The msp2 and p44 genes encode polymorphic major outer membrane proteins that are considered unique to the intraerythrocytic agent of Anaplasma marginale and the intragranulocytic agent of Anaplasma phagocytophilum, respectively. In the present study, however, we found an msp2 gene in A. phagocytophilum that was remarkably conserved among A. phagocytophilum s

21. Serotyping Isolates of Anaplasma phagocytophilum by Using Monoclonal Antibodies
Ten mouse monoclonal antibodies (MAbs) that react with Anaplasma phagocytophilum (the human granulocytic ehrlichiosis agent) Webster isolates were developed. Seven different isolates of A. phagocytophilum were subtyped with these MAbs. Western blot analysis revealed that these MAbs reacted mainly with 41- to 46-kDa Msp2 proteins. Six MAbs reacted with all is

22. Multiplex Real-Time PCR for Detection of Anaplasma phagocytophilum and Borrelia burgdorferi
A multiplex real-time PCR assay was developed for the simultaneous detection of Anaplasma phagocytophilum and Borrelia burgdorferi. The assay was tested on various Anaplasma, Borrelia, Erhlichia, and Rickettsia species, as well as on Bartonella henselae and Escherichia coli, and the assay was found to be highly specific for A. phagocytophilum and the Borreli

23. Anaplasma phagocytophilum Utilizes Multiple Host Evasion Mechanisms To Thwart NADPH Oxidase-Mediated Killing during Neutrophil Infection
Anaplasma phagocytophilum, the etiologic agent of human anaplasmosis, is a bacterial pathogen that specifically colonizes neutrophils. Neutrophils utilize the NADPH oxidase complex to generate superoxide (O2−) and initiate oxidative killing of microorganisms. A. phagocytophilum's unique tropism for neutrophils, however, indicates that it subverts and/or av

24. Antibiotic Susceptibilities of Anaplasma (Ehrlichia) phagocytophilum Strains from Various Geographic Areas in the United States
We tested the antibiotic susceptibilities of eight strains of Anaplasma phagocytophilum (the agent of human granulocytic ehrlichiosis) collected in various geographic areas of the United States, including Minnesota, Wisconsin, California, and New York. The results are homogeneous and show that doxycycline, rifampin, and levofloxacin are the most active antib
