| will the real agent of cat-scratch disease please stand up? | cat-scratch disease has been recognized since 1889 in association with the oculoglandular syndrome of parinaud. the epidemiologic association with cats was first made in 1931 and further substantiated throughout the years, refining the interaction predominantly to kittens. putative infectious agents have included numerous species of bacteria, chlamydiae, and viruses. the cultivation of afipia spp. in the late 1980s appeared to answer the mystery of the identity of the agent. however, even more r ... | 1996 | 8905096 |
| bartonella infections and hiv disease. | successful assessment and treatment of bartonella in hiv-seropositive people depends on nursing's fundamental role in the management of these bacterial infections. bartonella species are responsible for a variety of infections, including cat scratch disease and bacillary angiomatosis, which can be debilitating to people living with aids. this paper provides an overview of the clinical presentation and nursing management of bartonella infection in plwas. the author discusses common diagnostic pro ... | 1996 | 8906735 |
| does coinfection of bartonella henselae and fiv induce clinical disorders in cats? | it was found that bartonella henselae (b. henselae) may induce clinical disorders in cats in natural conditions from a comparison of the serological status for b. henselae with the serostatus for feline immunodeficiency virus (fiv) and several clinical characteristics in 170 domestic cats. seropositivity for b. henselae was not significantly different between fiv antibody-positive and -negative cats (18.4% vs 16.0%). the incidence of clinical characteristics were compared among four cat groups d ... | 1996 | 8908605 |
| serological study of bartonella henselae in cat scratch disease in japan. | it has become clear that bartonella henselae is a common cause of cat scratch disease (csd). the indirect fluorescence antibody (ifa) test for detection of igg and igm antibodies to b. henselae concerning csd showed that 5 (50%) of 10 patients with csd had a serum igg antibody titer of 1:128 or more and that 2 (20%) patients had a serum igm antibody titer of 1:20 or more. one of 7 asymptomatic members of patients' families (14%) had igg antibody to b. henselae at a titer of 1:256. igm antibody t ... | 1996 | 8908613 |
| survey of the seroprevalence of bartonella quintana in homeless people. | trench fever is caused by bartonella (rochalimaea) quintana, a small gram-negative rod that is transmitted by body lice. recently, b. quintana infections in homeless patients have been reported in the united states and europe. from october 1993 to october 1994, the seroprevalence of antibodies to b. quintana was assessed by indirect immunofluorescence in a prospective study of 221 nonhospitalized homeless people, 43 hospitalized homeless patients (cases), 250 blood donors, and 57 hospitalized ma ... | 1996 | 8909840 |

| verruga peruana: an infectious endemic angiomatosis. | microbial-related dysplastic and neoplastic angiomatous proliferative processes are seen with increased frequency, particularly in the acquired immunodeficiency syndrome (aids). the microbial-encoded or -induced mediators of angiopathogenesis in aids-associated kaposi's sarcoma and bacillary angiomatosis are actively being sought. the present review addresses the historical, epidemiologic, clinical, etio- and histopathogenic aspects of the verruga peruana (vp). vp is a disease thus far endemic t ... | 1995 | 8573607 |
| intracellular location of bartonella henselae cocultivated with vero cells and used for an indirect fluorescent-antibody test. | bartonella henselae, the major causative agent of cat scratch disease, was cocultivated with vero cells on chamber slides and visualized by indirect immunofluorescence by using a patient serum containing specific antibodies. confocal microscopy localized the granular b. henselae-specific fluorescence mainly around the nuclei of vero cells. by transmission electron microscopy, these granules were identified as clusters of multiple intracellular organisms. fixed slides with the monolayers of vero ... | 1995 | 8574831 |
| unraveling mysteries associated with cat-scratch disease, bacillary angiomatosis, and related syndromes. | the search for the infectious agents responsible for cat-scratch disease, bacillary angiomatosis, and related syndromes has a long and often circuitous history. recognition of the etiologic agents and a new understanding of the fundamental features of the epidemiology and natural history of modern day bartonella (formerly rochalimaea)-associated diseases culminate a multipartite story that combines clinical medicine, traditional microbiology, and novel technological approaches to solve a long-st ... | 1995 | 8903149 |
| serology to bartonella (rochalimaea) henselae may replace traditional diagnostic criteria for cat-scratch disease. | bartonella (rochalimaea) henselae has been identified as causative agent of cat-scratch disease (csd). employing an indirect fluorescence antibody test we found that 20 (100%) out of 20 children with suspected csd had serum titres to b. henselae of > or = 512. by contrast, in all but one of the controls (n = 332) including subjects exposed to the same cats, patients with diseases other than csd, and blood donors the antibody titres were < or = 256 (p < 0.001). however, significant regional diffe ... | 1995 | 8582404 |
| [cat scratch disease caused by bartonella henselae]. | bartonella henselae is an etiologic agent of cat-scratch disease and, in immunocompromised patients, of bacillary angiomatosis and other severe syndromes. cat-scratch disease usually presents as lymphadenopathy, which resolves spontaneously within 2-4 months. the utility of antibiotic therapy remains controversial. in tyrol four cases of human cat-scratch disease were diagnosed in children in 1994, yielding a prevalence of 0.7/100,000 per year. a 3-year-old boy had lymphadenitis coli since one y ... | 1995 | 8582740 |
| cluster of five children with acute encephalopathy associated with cat-scratch disease in south florida. | between august 12 and september 27, 1994, five children in south florida were hospitalized at a single hospital because of encephalopathy, presenting as status epilepticus, associated with cat-scratch disease (csd). diagnoses were confirmed by using an indirect fluorescent antibody test to detect antibody to bartonella henselae, the causative agent of csd. these cases represent the first cluster of csd encephalopathy cases to be recognized in the united states. the patients lived within 7 miles ... | 1995 | 8584313 |
