| [bartonella quintana endocarditis. aortic localization and mitral valve abscess]. | bartonella quintana is an exceptionally rare cause of endocarditis. the frequency of this condition is increasing and is probably underestimated because of the difficulty in diagnosing. the clinical context is that of socially deprived classes, the agent of transmission of the germ being body lice. the commonest valve affected is the aortic valve. this infection may also give rise to a mitral annulus abscess, as in this particular case. the diagnosis should be suspected in all cases of endocardi ... | 1998 | 9833092 |
| [bartonella endocarditis on native valves. apropos of 2 cases]. | the authors report two cases of bartonella endocarditis in native valves. the first case was a 15 year old north african girl who lived in poor social conditions and was admitted to hospital with pyrexia and congestive heart failure. investigations revealed massive mitral regurgitation due to ruptured chordae tendinae, vegetations on the pulmonary valve with severe pulmonary hypertension due to persistent ductus arteriosus. after antibiotic therapy, the patient underwent surgery for mitral valve ... | 1998 | 9833093 |
| evidence of reproductive failure and lack of perinatal transmission of bartonella henselae in experimentally infected cats. | five female specific pathogen-free (spf) cats inoculated intradermally with b. henselae and bacteremic for 4 weeks, and one cat inoculated with 0.9% nacl, were bred with uninfected spf male cats. the uninfected female became pregnant with one breeding, while three infected cats became pregnant 1-12 weeks later, after repeated breedings. two infected females either did not become pregnant or maintain pregnancies despite repeated breedings. infected cats produced anti-b. henselae igm and igg antib ... | 1998 | 9839873 |
| homologous protection but lack of heterologous-protection by various species and types of bartonella in specific pathogen-free cats. | cat-scratch disease (csd) is caused by bartonella henselae, and possibly by b. clarridgeiae. in immuno-compromised persons, b. henselae is one of the agents causing bacillary angiomatosis. domestic cats are the main reservoir of these bacteria, which are transmitted primarily from cat to cat by fleas. possible strategies to prevent the spread of infection among cats are to eliminate flea infestation or to prophylactically immunize cats. in order to develop an appropriate vaccine, it is important ... | 1998 | 9839874 |

| beware what you eat and drink, even while on haart. | people infected with hiv who are treated with highly active antiretroviral therapy (haart) are staying healthier for longer than ever before, but they still need to be cautious of exposure to foodborne and waterborne bacteria. the centers for disease control and prevention (cdc) lists several pathogens which can be dangerous to persons with hiv/aids, including mycobacterium avium complex (mac) and cryptococcosis. people with hiv who are infected by these pathogens tend to suffer from more severe ... | 1999 | 11366423 |
| 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 |
| 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 |

| [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 |
| 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 |
| 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 |
