| ecological fitness and strategies of adaptation of bartonella species to their hosts and vectors. | bartonella spp. are facultative intracellular bacteria that cause characteristic hostrestricted hemotropic infections in mammals and are typically transmitted by blood-sucking arthropods. in the mammalian reservoir, these bacteria initially infect a yet unrecognized primary niche, which seeds organisms into the blood stream leading to the establishment of a long-lasting intra-erythrocytic bacteremia as the hall-mark of infection. bacterial type iv secretion systems, which are supra-molecular tra ... | 2009 | 19284965 |
| polymerase chain reaction for pathogen identification in persistent pediatric cervical lymphadenitis. | to study routine culture-negative persistent cervical lymphadenitis in children treated surgically during a 10-year period (december 26, 1997, to october 1, 2007) at a single institution. | 2009 | 19289701 |
| bacillary angiomatosis. | an infection with bartonella henselae transmitted from domestic cats to humans by scratching normally leads to cat-scratch disease. when the human host has severe immunosuppression or hiv infection, the potentially life-threatening disease bacillary angiomatosis can develop. a 79-year-old man presented with livid-erythematous, angioma-like skin lesions. we considered a cutaneous infiltrate from his known chronic lymphocytic leukemia, merkel cell carcinoma, cutaneous metastases of internal tumors ... | 2009 | 19298547 |
| a translocated protein of bartonella henselae interferes with endocytic uptake of individual bacteria and triggers uptake of large bacterial aggregates via the invasome. | bartonella henselae enters human endothelial cells (ecs) by two alternative routes: either by endocytosis, giving rise to bartonella-containing vacuoles or by invasome-mediated internalization. only the latter process depends on the type iv secretion system virb/vird4 and involves the formation of cell surface-associated bacterial aggregates, which get engulfed by ec membranes in an f-actin-dependent manner, eventually resulting in their complete internalization. here, we report that among the v ... | 2009 | 19302579 |
| [cat scratch disease with bone involvement: a case report and literature review]. | cat scratch disease is an infectious disease caused by bartonella henselae. most of the patients present with a lymphadenopathy associated with a local infection at the site of the cat scratch. disseminated infection is uncommon. | 2009 | 19303175 |
| evolutional and geographical relationships of bartonella grahamii isolates from wild rodents by multi-locus sequencing analysis. | to clarify the relationship between bartonella grahamii strains and both the rodent host species and the geographic location of the rodent habitat, we have investigated 31 b. grahamii strains from ten rodent host species from asia (japan and china), north america (canada and the usa), and europe (russia and the uk). on the basis of multi-locus sequencing analysis of 16s rrna, ftsz, glta, groel, ribc, and rpob, the strains were classified into two large groups, an asian group and an american/euro ... | 2009 | 19219487 |
| infection and replication of bartonella species within a tick cell line. | bartonella species are fastidious, gram negative bacteria, some of which are transmitted by arthropod vectors, including fleas, sandflies, and lice. there is very little information regarding the interaction and/or transmission capabilities of bartonella species by ticks. in the present study, we demonstrate successful infection of the amblyomma americanum cell line, aae12, by seven bartonella isolates and three candidatus bartonella species by electron or light microscopy. with the exception of ... | 2009 | 19242658 |
