| comparative genomics of emerging human ehrlichiosis agents. | anaplasma (formerly ehrlichia) phagocytophilum, ehrlichia chaffeensis, and neorickettsia (formerly ehrlichia) sennetsu are intracellular vector-borne pathogens that cause human ehrlichiosis, an emerging infectious disease. we present the complete genome sequences of these organisms along with comparisons to other organisms in the rickettsiales order. ehrlichia spp. and anaplasma spp. display a unique large expansion of immunodominant outer membrane proteins facilitating antigenic variation. all ... | 2006 | 16482227 |
| detection of ehrlichia chaffeensis in brazilian marsh deer (blastocerus dichotomus). | ehrlichia chaffeensis was detected for the first time in blood samples from brazilian marsh deers (blastocerus dichotomus) captured in the marshes of parana river in southeast brazil in 1998. seven edta-blood samples from deers were analyzed by pcr and nested pcr for presence of ehrlichia chaffeensis, ehrlichia ewingii, ehrlichia canis, neoriickettsia risticii, anaplasma phagocytophilum and anaplasma marginale. three samples showed positive reactions for e. chaffeensis and anaplasma marginale. n ... | 2006 | 16621285 |

| lymph node aspirate from a california wine-country dog. | a 4-year-old, male golden retriever was presented to the veterinary medical teaching hospital at the university of california-davis with a history of lethargy, inappetance, and vomiting. the patient had generalized lymphadenomegaly, marked thrombocytopenia, mild anemia, and moderate hypoalbuminemia. moderate to marked histiocytic inflammation and lymphocytic-plasmacytic reactivity of the mesenteric, left popliteal, and right mandibular lymph nodes were diagnosed cytologically. many macrophages c ... | 2006 | 16783722 |
| prevalence of mycoplasma haemofelis, 'candidatus mycoplasma haemominutum', bartonella species, ehrlichia species, and anaplasma phagocytophilum dna in the blood of cats with anemia. | hemoplasmas are known causes of anemia in some cats and some bartonella species have been associated with anemia in people and in dogs. in this retrospective study, we used polymerase chain reaction (pcr) assays to determine the prevalence rates of mycoplasma haemofelis, 'candidatus m haemominutum', a phagocytophilum, ehrlichia species, and bartonella species dna in the blood of cats with anemia and a control group of healthy cats. dna of the organisms was amplified from 22 of 89 cats with anemi ... | 2007 | 16846745 |
| prevalence of dna of mycoplasma haemofelis, 'candidatus mycoplasma haemominutum,' anaplasma phagocytophilum, and species of bartonella, neorickettsia, and ehrlichia in cats used as blood donors in the united states. | to identify the prevalence of dna of mycoplasma haemofelis; 'candidatus mycoplasma haemominutum'; anaplasma phagocytophilum; and species of bartonella, neorickettsia, and ehrlichia in blood of cats used as blood donors in the united states. | 2006 | 16948578 |

| new findings on members of the family anaplasmataceae of veterinary importance. | members of the family anaplasmataceae are obligate intracellular gram-negative bacteria that naturally infect a variety of wild and domestic animal species, the spillover of which may lead to zoonosis. i discuss new findings on members of the family anaplasmataceae of veterinary importance and therefore, i will describe the recent findings on neorickettsia risticii in the trematode and related neorickettsia species. i also will review the recent progress on aegyptianella pullorum and other aegyp ... | 2006 | 17114752 |
