13. Detecção e diferenciação de Anaplasma marginalee Anaplasma centralepor reação em cadeia de polimerase (PCR)
O patógeno intracelular Anaplasma marginale (Rickettsiales: Anaplasmataceae) é endêmico em muitas regiões tropicais e subtropicais do mundo. A infecção do bovino com A. marginale causa anaplasmose bovina, devido à replicação do microrganismo nos eritrócitos do hospedeiro, sendo responsável por consideráveis perdas econômicas à criação de gado

14. Diagnóstico molecular de agentes da família Anaplasmataceae em cães com sinais clínicos e microscópios de erliquiose
Erliquioses são importantes enfermidades emergentes transmitidas por carrapatos que podem afetar os animais e o homem. Em cães, as manifestações clínicas da erliquiose causada por diferentes membros da Família Anaplasmataceae são similares entre si e entre outras enfermidades de manifestação sistêmica. A observação de inclusões em leucócitos e

15. Perfil sanitário de onças-pintadas (Panthera onca) de vida livre no Pantanal Sul do Mato Grosso do Sul - Brasil / Health profile of free-ranging jaguars (Panthera onca) in Pantanal, Mato Grosso do Sul State - Brazil
Few studies have been conducted to investigate the health of free-ranging jaguars. In order to obtain better parameters for clinical evaluation of this endangered species, clinical exams, hemogram, biochemical tests and ecological monitoring were done for 10 jaguars in the Pantanal region - Corumbá City, Mato Grosso do Sul State. This project also evaluated

16. Produção das proteínas recombinantes AM254, VirB9 e VirB10, de Anaplasma marginale e avaliação preliminar de sua antigenicidade. / Production of recombinant proteins AM254, VirB9 and VirB10 of Anaplasma marginale and preliminary evaluation its antigenicity.
Anaplasma marginale (Ricktsialles: Anaplasmataceae) is a ricketsial hemoparasite responsible for causing great economic losses in cattle from tropical and subtropical regions. The objectives of this work were to produce the recombinant membrane proteins AM254, VirB9 and VirB10 and to evaluate its possible antigenicity. The genes am254, virB9 and virB10 were

17. Produção, caracterização e avaliação da imunogenicidade do complexo protéico MSP1 recombinante (rMSP1a erMSP1b) de isolado paranaense do anaplasma marginale
The Anaplasma marginale (Rickettsiales: Anaplasmataceae) is a pathogen that cause bovine anaplasmosis. This disease occurs in world wide, and it is more frequently in tropical and subtropical areas, causing important economic losses in cattle herds. Six Major Surface Protein (MSP1a, MSP1b, MSP2, MSP3, MSP4 and MSP5) have been identified in A. marginale. The

18. PREVALÊNCIA DE ANTICORPOS ANTI Anaplasma marginale (RICKETTSIALES: ANAPLASMATACEAE) EM BOVINOS NA MESORREGIÃO DO MÉDIO PARAÍBA
Realizou-se a pesquisa de anticorpos da classe IgG anti Anaplasma marginale através do ensaio de imunoadsorção enzimática (ELISA) indireto em 223 amostras de soros de bovinos provenientes de oito municípios da mesorregião do Médio Paraíba, estado do Rio de Janeiro. A prevalência observada foi de 98,21%. Das amostras positivas, 36,32% possuíam o tí

19. Molecular Characterization of Aegyptianella pullorum (Rickettsiales, Anaplasmataceae)
We sequenced the 16S rRNA and groEL genes of Aegyptianella pullorum, a small bacterium that infects and replicates only in avian red blood cells. A specific PCR test was developed to analyze A. pullorum DNA. Phylogenic analysis revealed A. pullorum is most closely related to Anaplasma spp.

20. Divergent Interactions of Ehrlichia chaffeensis- and Anaplasma phagocytophilum-Infected Leukocytes with Endothelial Cell Barriers
Human anaplasmosis (formerly human granulocytic ehrlichiosis) and human monocytic ehrlichiosis (HME) are emerging tick-borne infections caused by obligate intracellular bacteria in the family Anaplasmataceae. Clinical findings include fever, headache, myalgia, leukopenia, thrombocytopenia, and hepatic inflammatory injury. Whereas Ehrlichia chaffeensis

21. Characterization of Anaplasma marginale Isolated from North American Bison
Anaplasma marginale (Rickettsiales: Anaplasmataceae), a tick-borne pathogen of cattle, is endemic in tropical and subtropical regions of the world. Although serologic tests have identified American bison, Bison bison, as being infected with A. marginale, the present study was undertaken to confirm A. marginale infection and to characterize isolates obtained

22. Anaplasma marginale msp1α Genotypes Evolved under Positive Selection Pressure but Are Not Markers for Geographic Isolates
Anaplasma marginale (order Rickettsiales, family Anaplasmataceae), a tick-borne pathogen of cattle, is endemic in tropical and subtropical regions of the world. Many geographic isolates of A. marginale occur in the United States and have been identified by major surface protein 1a (MSP1a), which varies in sequence and molecular weight due to different number

23. Major Histocompatibility Complex Class II DR-Restricted Memory CD4+ T Lymphocytes Recognize Conserved Immunodominant Epitopes of Anaplasma marginale Major Surface Protein 1a
Native major surface protein 1 (MSP1) of Anaplasma marginale, composed of covalently associated MSP1a and MSP1b proteins, stimulates protective immunity in cattle against homologous and heterologous strain challenge. Protective immunity against pathogens in the family Anaplasmataceae involves both CD4+ T cells and neutralizing immunoglobulin G. Thus, an effe
