carboxyl-terminal processing protease for the d1 precursor protein: cloning and sequencing of the spinach cdna.a previous study has demonstrated that the carboxyl-terminal (c-terminal) processing protease in spinach for the d1 precursor protein (pdl) of the photosystem ii reaction center is a monomeric protein of about 45 kda. based on the amino acid sequence data of the purified protease, a cdna clone encoding the enzyme has been identified and sequenced, from a spinach green leaf cdna library. in order to determine the 5' end of the transcript, the rapid amplification of cdna end (5'-race) technique wa ...19968616242
new serotype of bartonella henselae in endocarditis and cat-scratch disease.the fastidious nature of bartonella henselae is such that demonstration of clinical infection relies mainly on serological or molecular biological methods. only five isolates have been obtained from patients with cat-scratch disease (csd) and none from endocarditis.19968618486
[cat-scratch disease and other infections caused by bartonella species].bartonella henselae, the causative agent of cat-scratch disease, was identified recently by dna amplification techniques. several other bartonellae (most of which were called rochalimaea before) cause disease in humans: b. bacilliformis (carrion's disease), b. elizabethae (endocarditis) and b. quintana (bacillary angiomatosis and peliosis, chronic bacteraemia and endocarditis, trench fever). b. henselae is transmitted to humans by scratch or bite of a bacteraemic, but asymptomatic, cat, which ev ...19968618634

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 ...19968905096
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 ...19968906735
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 ...19968908605
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 ...19968908613
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 ...19968909840
