| [seroepidemiology of bartonella henselae infection in a risk group]. | bartonella henselae infections are closely related to a number of clinical conditions of growing interest in our environment. as cats are the reservoir, and their bites and scratches are the main transmission mechanism, we attempted to study the seroepidemiology of the infection caused by this microorganism in a risk group of patients (cat owners) and a control group (blood donors). | 1998 | 9930000 |
| blood parasites of shrews from pennsylvania. | we examined 30 sorex cinereus, 5 sorex fumeus, and 21 blarina brevicauda collected from pennsylvania in 1995 for blood parasites. trypomastigotes of trypanosoma sp. were visible in 13% of the s. cinereus. ten percent of s. cinereus, 20% of s. fumeus, and 14% of b. brevicauda were infected with bartonella sp. (or spp.). in s. cinereus, we detected no concurrent trypanosoma and bartonella infections. | 1998 | 9920338 |
| [bartonellosis. ii. other bartonella responsible for human diseases]. | in addition to bartonella henselae, five other bartonella species were involved in human pathology. as for b. henselae, ectoparasites seem to be responsible for the transmission of most or all these bacterial species. b. bacilliformis is responsible for carrion's disease that occurs in some valleys of colombia, ecuador and peru. this disease is transmitted by biting of infected sandflies. the bacterial reservoir is constituted by humans only. that disease occurs either as an acute form with seve ... | 1999 | 9920964 |

| cat-scratch disease causing status epilepticus in children. | status epilepticus from cat-scratch encephalopathy is often recalcitrant to usual therapies, causing treatment to focus on critical care management of the patient that may require aggressive interventions, such as continuous pentobarbital administration. we describe two children whose initial clinical presentation of cat-scratch disease was status epilepticus with normal cerebrospinal fluid studies. a history of cat exposure (specifically, kitten and/or fleas), regional lymphadenopathy, and a pa ... | 1999 | 9932833 |
| interactions of bartonella henselae with vascular endothelial cells. | the emerging human pathogen bartonella henselae has the remarkable capacity to colonise vascular tissues and to stimulate vasoproliferative tumour growth. although the molecular principle of bacterium-induced neovascularisation (angiogenesis) is still unclear, recent studies have indicated a novel mechanism of endothelial colonisation that involves the formation, engulfment and uptake of a large bacterial aggregate. | 1999 | 10047560 |
| body lice as tools for diagnosis and surveillance of reemerging diseases. | body lice are vectors of three bacteria which cause human disease: rickettsia prowazekii, the agent of epidemic typhus; bartonella quintana, the agent of trench fever; and borrelia recurrentis, the agent of relapsing fever. a recrudescence of body lice is being observed as the numbers of individuals living under social conditions which predispose individuals to infestation have increased. because this phenomenon may lead to the reemergence of infections transmitted by body lice, we aimed to asse ... | 1999 | 9986818 |
| bartonella alsatica sp. nov., a new bartonella species isolated from the blood of wild rabbits. | bartonella species are considered as emerging human pathogens, with at least six different species pathogenic or possibly pathogenic for humans. however, little is known about bartonella distribution, species polymorphism and pathogenicity in mammalian species. the objective of this work was to determine the presence, the frequency and the distribution of bartonella species in wild rabbits (oryctolagus cuniculus) caught in warrens in alsace, france. humans may come into contact with wild rabbits ... | 1999 | 10028274 |

| detection of bartonella henselae dna by two different pcr assays and determination of the genotypes of strains involved in histologically defined cat scratch disease. | cat scratch disease (csd) is a common cause of subacute regional lymphadenopathy, not only in children but also in adults. serological and molecular studies demonstrated that bartonella henselae is the etiologic agent in most cases of csd. amplification of b. henselae dna in affected tissue and detection of antibodies to b. henselae are the two mainstays in the laboratory diagnosis of csd. we designed a retrospective study and investigated formalin-fixed, paraffin-embedded lymph nodes from 60 pa ... | 1999 | 10074515 |
| bartonella koehlerae sp. nov., isolated from cats. | two of the 25 bartonella isolates recovered during a prevalence study of bartonella henselae bacteremia in domestic cats from the greater san francisco bay region were found to differ phenotypically and genotypically from all prior b. henselae isolates. these isolates, c-29 and c-30, which were recovered from the blood of two pet cats belonging to the same household, grew on chocolate agar as pinpoint colonies following 14 days of incubation at 35 degrees c in a candle jar but failed to grow on ... | 1999 | 10074535 |

| [cat-scratch disease: series of 14 cases. the diagnostic usefulness of serology]. | disease by cat scratch (csd) is a syndrome characterized by regional adenopathies following cat scratch or bite. despite knowing the etiologic agent of the same, there is still controversy in the diagnosis of the syndrome in daily clinical practice. | 1999 | 10069107 |
| involvement of host cell tyrosine phosphorylation in the invasion of hep-2 cells by bartonella bacilliformis. | we have provided evidence that exposure of human cells to protein kinase inhibitors results in decreased invasion of these cells by bartonella bacilliformis in a dose-dependent manner. preincubation of human laryngeal epithelial cells in the presence of genistein, a tyrosine protein kinase inhibitor, decreased the invasion of these cells by b. bacilliformis significantly. further, exposure of normal human umbilical vein endothelial cells to staurosporine, a potent inhibitor of protein kinase c a ... | 1999 | 10077844 |

| cat scratch disease diagnosed by polymerase chain reaction in a patient with suspected tuberculous lymphadenitis. | we present a patient diagnosed as having tuberculous lymphadenitis after lymph node biopsy and referred for tuberculous therapy. on review, because of recent cat exposure, she was tested for cat scratch disease (csd), but serological tests for bartonella henselae were negative. however, the diagnosis of csd was confirmed, and tuberculosis excluded, by polymerase chain reaction techniques. this case serves as a reminder that csd may mimic tuberculosis histologically and that sensitive molecular d ... | 1999 | 10078182 |
| the iala invasion gene of bartonella bacilliformis encodes a (de)nucleoside polyphosphate hydrolase of the mutt motif family and has homologs in other invasive bacteria. | the product of the iala invasion gene of bartonella bacilliformis has been expressed as a thioredoxin fusion protein. it is a (di)nucleoside polyphosphate hydrolase of the mutt motif protein family with strong sequence similarity to plant diadenosine tetraphosphate hydrolases. it hydrolyses nucleoside and dinucleoside polyphosphates with four or more phosphate groups, always producing an ntp as one product. diadenosine tetraphosphate (ap4a) is the preferred substrate with a km of 10 microm and a ... | 1999 | 10080922 |
