isolated cranial granuloma induced by pneumocystis carinii. 19938514284
pneumocystis carinii is not universally transmissible between mammalian species.in a series of five experiments, we attempted to transmit pneumocystis carinii from ferrets to scid mice by intratracheal inoculation. using highly specific and sensitive assay techniques, we could not document infection of scid mice by p. carinii isolated from ferrets. in contrast, under identical inoculation conditions, p. carinii was easily transmissible from one scid mouse to another. these results indicate that p. carinii organisms, at least those isolated from ferrets, have a restricted ho ...19938514391
further evidence of host species-specific variation in antigens of pneumocystis carinii using the polymerase chain reaction.to further elucidate the extent of variation among pneumocystis carinii obtained from different mammalian hosts, polymerase chain reaction (pcr) analysis of the genes encoding two antigens of p. carinii was done. using primers based on the ferret p. carinii glycoprotein (gp)a gene and the rat p. carinii 45- to 55-kda antigen gene, amplification was attempted with dna isolated from p. carinii-infected ferret, rat, mouse, and human lungs. for both genes, amplification was successful only with p. c ...19938515107
gender differences in reported aids-indicative diagnoses.to compare aids-defining conditions in women and men, us adult aids cases diagnosed between january 1988 and june 1991 and reported to the centers for disease control and prevention through june 1992 were examined. for most aids-defining conditions, the prevalence was similar for women and men when differences in race/ethnicity and mode of transmission were accounted for. pneumocystis carinii pneumonia was the most prevalent condition (> 50%) regardless of gender, race/ethnicity, or mode of tran ...19938515133
[anesthetic considerations in patients with human immunodeficiency virus infection].in the last few years many articles have been published on aids, the mechanism of transmission, prophylaxis and therapeutic possibilities; however, very few publications are available related with anesthesia of patients infected with hiv or aids. the authors have therefore undertaken this review in which following a brief description of the etiology, pathogenesis, physiopathology and treatment of the disease, the problems of anesthesia are specifically dealt with. the need for knowing the differ ...19938516524

the art of parasite survival.parasites develop and survive in an environment which is often hostile to them. when facing aggressive conditions parasites are able to use various and complex strategies. echinococcus granulosus, toxocara canis, pneumocystis carinii, entamoeba or toxoplasma gondii are able to seclude from the environment when stressed by surrounding (immunologic or non-immunologic) aggressive factors. specific antigens which exert a functional activity during a short period of time appear to be concealed from t ...19958520537
uptake and metabolism of l-serine by pneumocystis carinii carinii.serine is an important amino acid that is utilized in the biosyntheses of proteins and lipids. it is directly incorporated into the head group of phosphatidylserine, which in turn can be converted to other phospholipids. also, it is required for the formation of long chain bases, precursors of sphingolipids. uptake and incorporation of radiolabeled serine into both lipids and acid-precipitable material were demonstrated in pneumocystis carinii carinii organism preparations freshly isolated from ...19958520579
analysis of genetic diversity at the arom locus in isolates of pneumocystis carinii.the dna sequences of a portion of the 5-enolpyruvyl shikimate phosphate synthase domain of the arom gene, encoding the pentafunctional arom protein, were determined from isolates of pneumocystis carinii from five mammalian host species (rat, human, ferret, rabbit and mouse). high levels of genetic divergence were found among p. carinii derived from different host species, 7-22% at the dna sequence level, and 7-26% at the derived amino acid sequence level. two separate and distinct sequences were ...19958520580

clinical significance of resolution of chest x-ray findings in hiv-infected children with lymphocytic interstitial pneumonitis (lip).lymphocytic interstitial pneumonitis (lip) in hiv-infected children is generally associated with better prognosis as compared with children with pneumocystis carinii pneumonia (pcp). we prospectively studied 12 cases of hiv-infected children with lip over a 4-year period in an effort to document one aspect of the natural history of this clinical entity. severe cd4 lymphocytopenia was associated with complete resolution of the chest x-ray findings in five patients, one of whom died of disseminate ...19958577544
[successful prevention of pneumocystis carinii infection with 1,920 mg of trimethoprim-sulfamethoxazole daily in patients with malignant hematopoietic diseases].during 1991-94 we treated 51 patients with acute myeloid leukaemias and 3 patients with a myelodysplastic syndrome of refractory anaemia with excess of blasts in transformation. the patients received trimethoprim-sulphamethoxazole (tmp-smx) 1,920 mg daily as a prophylaxis of pneumocystis carinii infections and selective decontamination of gastrointestinal tract. the majority of patients received tmp-smx in their first course of chemotherapy with daunorubicin and cytosine arabinoside. only one of ...19958578700
pentamidine is an uncoupler of oxidative phosphorylation in rat liver mitochondria.pentamidine is a cationic drug that is used for the treatment of african trypanosomiasis, leishmaniasis, and pneumocystis carinii pneumonia. when incubated with pharmacological concentrations of pentamidine, some of the etiologic agents of those diseases reach internal concentrations close to 1.0 mm. in this work pentamidine is shown to exhibit characteristics of a cationic uncoupler of oxidative phosphorylation in isolated rat liver mitochondria: it released respiratory control, enhanced the la ...19968579363
pneumocystis carinii pneumonia in preterm infants: report of two cases successfully diagnosed by non-bronchoscopic bronchoalveolar lavage.we present two cases of pneumocystis carinii pneumonia in apparently immunocompetent preterm infants presenting with unexplained respiratory distress associated with a predominantly interstitial process on the chest radiograph. definite diagnosis was promptly established on the detection of cyst forms in the lung fluid obtained by non-bronchoscopic bronchoalveolar lavage, and a favourable outcome was achieved.19958580633
benefit of oral zinc supplementation as an adjunct to zidovudine (azt) therapy against opportunistic infections in aids.zinc is perhaps the most important trace element for immune function. congenital or acquired zinc deficiencies are associated with immune abnormalities and increased susceptibility to infectious diseases. aids subjects suffer from reduced zinc bioavailability, more severe in stage iv than in stage iii. such zinc deficiency causes, among other effects, a profound reduction in the biological activity of one of the thymic hormones, thymulin (zinc-facteur-timique-serique, znfts). with these premises ...19958582783
characterization of pneumocystis carinii infection in sorex araneus from southern finland.histologic and quantitative techniques were compared in an evaluation of the intensity of pneumocystis carinii infection in common shrews (sorex araneus) at espoo, southern finland, from september 1992 to may 1993. the histological scores were comparable to the results of the cyst count technique. the number of p. carinii cysts found in common shrews was low compared to those reported by others in clinically ill laboratory rats. the inflammatory changes detected in the lung sections had no signi ...19958583642

disseminated penicillium marneffei infection in human immunodeficiency virus-infected children.disseminated infection with the fungus penicillium marneffei is one of the most common opportunistic infections in human immunodeficiency virus (hiv) disease in northern thailand. we report the clinical, laboratory and therapeutic features of 21 human immunodeficiency virus-infected children with disseminated p. marneffei who were prospectively followed. significant clinical and laboratory features included generalized lymphadenopathy (90%), hepatomegaly (90%), body temperature > 38.5 degrees c ...19958584358
comparison of a rapid nonisotopic polymerase chain reaction assay with four commonly used methods for the early diagnosis of human immunodeficiency virus type 1 infection in neonates and children.to initiate antiretroviral therapy and prophylaxis for pneumocystis carinii pneumonia, it is important to identify human immunodeficiency virus (hiv-1)-infected infants as soon after birth as possible. this study was undertaken to evaluate a novel 5-hour nonisotopic (ni) polymerase chain reaction (pcr) assay (amplicor pcr; roche molecular systems) and four other commonly used hiv-1 diagnostic tests including culture, oligonucleotide hybridization pcr, p24 antigen and immune complex-dissociated ( ...19958584360
[diagnostic value of protected bronchoalveolar lavage in hiv-associated pneumonia].the concept of the protected bronchoalveolar lavage (pbal) is to improve the diagnostic yield in bacterial pneumonia by unifying the high sensitivity of bronchoalveolar lavage (bal) and specificity of the protected specimen brush (psb). hiv-infected patients have been shown to have a high incidence of bacterial pneumonia as well as bacterial colonisation of the tracheobronchial tree. we therefore studied the value of pbal in this population.19958584525
evaluation of potent inhibitors of dihydrofolate reductase in a culture model for growth of pneumocystis carinii.many antifolates are known to inhibit dihydrofolate reductase from murine pneumocystis carinii, with 50% inhibitory concentrations (ic50s) ranging from 10(-4) to 10(-11) m. the relationship of the potency against isolated enzyme to the potency against intact murine p. carinii cells was explored with 17 compounds that had proven selectivity for or potency against p. carinii dihydrofolate reductase. pyrimethamine and one analog were inhibitory to p. carinii in culture at concentrations two to seve ...19958585722
pteroylpolyglutamate synthesis by lung- and culture-derived pneumocystis carinii.pneumocystis carinii synthesizes folates de novo from exogenous p-aminobenzoic acid (paba). lung-derived organisms take up [3h]paba in vitro except in the presence of sulfamethoxazole. supernatants from spinner-flask cultures take up [3h]paba if they were inoculated with lungs from infected rats, but not if they were inoculated with lungs from uninfected rats. p. carinii folates consist primarily of pteroylpentaglutamates. plasmodium falciparum, in contrast, contains primarily pteroyltetraglutam ...19958586276
