The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world. (Stedman, 25th ed; from Rook et al., Textbook of Dermatology, 4th ed, p2445)

Mushroom worker's lung resulting from indoor cultivation of Pleurotus osteatus. (1/1360)

Indoor cultivation of oyster mushroom Pleurotus osteatus lead to an outbreak of extrinsic allergic alveolitis in two workers. High titer of indirect fluorescent antibody and positive precipitins against basidiospores of P. osteatus were demonstrated in sera of the patients. Mushroom workers should protect themselves from the basidiospores, being aware of their pathogenicity.  (+info)

Variants of a Cryptococcus neoformans strain elicit different inflammatory responses in mice. (2/1360)

The virulence of Cryptococcus neoformans isolates with high and low extracellular proteolytic activity was investigated in mice. No consistent relationship between proteolytic activity and virulence was observed, but isolates derived from one strain were shown to elicit different inflammatory responses.  (+info)

Detection of cell wall mannoprotein Mp1p in culture supernatants of Penicillium marneffei and in sera of penicilliosis patients. (3/1360)

Mannoproteins are important and abundant structural components of fungal cell walls. The MP1 gene encodes a cell wall mannoprotein of the pathogenic fungus Penicillium marneffei. In the present study, we show that Mp1p is secreted into the cell culture supernatant at a level that can be detected by Western blotting. A sensitive enzyme-linked immunosorbent assay (ELISA) developed with antibodies against Mp1p was capable of detecting this protein from the cell culture supernatant of P. marneffei at 10(4) cells/ml. The anti-Mp1p antibody is specific since it fails to react with any protein-form lysates of Candida albicans, Histoplasma capsulatum, or Cryptococcus neoformans by Western blotting. In addition, this Mp1p antigen-based ELISA is also specific for P. marneffei since the cell culture supernatants of the other three fungi gave negative results. Finally, a clinical evaluation of sera from penicilliosis patients indicates that 17 of 26 (65%) patients are Mp1p antigen test positive. Furthermore, a Mp1p antibody test was performed with these serum specimens. The combined antibody and antigen tests for P. marneffei carry a sensitive of 88% (23 of 26), with a positive predictive value of 100% and a negative predictive value of 96%. The specificities of the tests are high since none of the 85 control sera was positive by either test.  (+info)

Aspergillus meningitis: diagnosis by non-culture-based microbiological methods and management. (4/1360)

The performance of antibody detection, antigen detection, and Aspergillus genus-specific PCR for diagnosing Aspergillus meningitis was investigated with 26 cerebrospinal fluid (CSF) samples obtained from a single patient with proven infection caused by Aspergillus fumigatus. Immunoglobulin G antibodies directed against Aspergillus were not detected by enzyme-linked immunosorbent assay in CSF or serum. The antigen galactomannan was detected in the CSF 45 days before a culture became positive, and Aspergillus DNA was detected 4 days prior to culture. Decline of the galactomannan antigen titer in the CSF during treatment with intravenous and intraventricular amphotericin B and intravenous voriconazole corresponded with the clinical response to treatment.  (+info)

Production of specific monoclonal antibodies to Aspergillus species and their use in immunohistochemical identification of aspergillosis. (5/1360)

Two anti-Aspergillus murine monoclonal antibodies (MAbs), designated 164G and 611F, have been produced; both specifically recognize cytoplasmic antigens of A. fumigatus, A. flavus, and A. niger by enzyme-linked immunosorbent assay. The MAbs can identify Aspergillus spp. both in frozen sections by immunofluorescence and in paraffin-embedded clinical specimens by immunofluorescence and immunoperoxidase staining.  (+info)

Molecular cloning, characterization, and expression of the M antigen of Histoplasma capsulatum. (6/1360)

The major diagnostic antigens of Histoplasma capsulatum are the H and M antigens, pluripotent glycoproteins that elicit both humoral and T-cell-mediated immune responses. These antigens may play a role in the pathogenesis of histoplasmosis. M antigen is considered immunodominant because antibodies against it are the first precipitins to arise in acute histoplasmosis and are commonly present during all phases of infection. The biological activity of monomolecular M antigen and its ability to elicit a protective immune response to H. capsulatum are largely unknown. A molecular approach was used to identify the biological nature of M antigen, including its purification from histoplasmin, partial digestion with proteinases, and reverse-phase high-performance liquid chromatography to separate the released peptides. The amino acid sequences of the purified peptides were obtained by Edman degradation, and using degenerate oligonucleotide primers for PCR, a 321-bp fragment of the gene encoding the M antigen was amplified from genomic H. capsulatum DNA. This fragment was used to screen an H. capsulatum genomic DNA library, leading to the isolation, cloning, and sequencing of the full-length gene. The M gene consists of 2, 187-bp DNA encoding a protein of 80,719 Da, which has significant homology to catalases from Aspergillus fumigatus, Aspergillus niger, and Eimericella nidulans. A cDNA was generated by reverse transcription-PCR and cloned into the expression vector pQE40. The identity of the cloned, expressed protein was confirmed by Western blotting. The recombinant fusion protein was immunoreactive with monoclonal antibodies raised against M antigen, with polyclonal mouse anti-M antiserum, and with a serum sample from a patient with histoplasmosis. The gene encoding the major immunodominant M antigen of H. capsulatum is a presumptive catalase, and the recombinant protein retains serodiagnostic activity.  (+info)

Two-dimensional electrophoresis of Malassezia allergens for atopic dermatitis and isolation of Mal f 4 homologs with mitochondrial malate dehydrogenase. (7/1360)

The yeast Malassezia furfur is a natural inhabitant of the human skin microflora that induces an allergic reaction in atopic dermatitis. To identify allergens of M. furfur, we separated a crude preparation of M. furfur antigens as discrete spots by 2-D PAGE and detected IgE-binding proteins using sera of atopic dermatitis patients. We identified the known allergens, Mal f 2 and Mal f 3, and determined N-terminal amino acid sequences of six new IgE-binding proteins including Mal f 4. The cDNA and genomic DNA encoding Mal f 4 were cloned and sequenced. The gene was mitochondrial malate dehydrogenase and encoded Mal f 4 composed of 315 amino acids and a signal sequence of 27 amino acids. We purified Mal f 4, which had a molecular mass of 35 kDa from a membrane fraction of a lysate of cultured cells. Thirty of 36 M. furfur-allergic atopic dermatitis patients (83.3%) had elevated serum levels of IgE to purified Mal f 4, indicating that Mal f 4 is a major allergen. There was a significant correlation of the Phadebas RAST unit values of Mal f 4 and the crude antigen, but not between Mal f 4 and the known allergen Mal f 2.  (+info)

Heat shock protein 70 (hsp70) as a major target of the antibody response in patients with pulmonary cryptococcosis. (8/1360)

Cryptococcus neoformans causes infection in individuals with defective T cell function, such as AIDS, as well as without underlying disease. It has been suggested that humoral as well as cellular immunity might play an important role in the immune response to C. neoformans infection. We have recently shown, using immunoblotting, that the 70-kD hsp family of C. neoformans was the major target molecule of the humoral response in murine pulmonary cryptococcosis. In this study we also used immunoblotting to define the antibody responses in the sera of 24 patients with pulmonary cryptococcosis: 21 proven and three suspected diagnoses. Anti-C. neoformans hsp70 antibody was detected in 16 of 24 (66.7%) patients with pulmonary cryptococcosis. Fourteen of 17 (82.3%) patients with high antigen titres (> or = 1:8) and two of seven (28.6%) patients with low titres (< or = 1:4) had detectable levels of anti-hsp70 antibody. Sera from patients positive for anti-hsp70 antibody showed high titres in the Eiken latex agglutination test for the detection of serum cryptococcal antigen. Our results indicate that the 70-kD hsp family from C. neoformans appears to be a major target molecule of the humoral response, not only in murine pulmonary cryptococcosis, but also in human patients with pulmonary cryptococcosis.  (+info)

BackgroundAn experimental approach for improving vaccine efficacy involves targeting antigens to mannose receptors (MRs) on dendritic cells (DCs) and other professional antigen presenting cells. Previously, we demonstrated that mannosylated Pichia pastoris-derived recombinant proteins exhibited increased immunogenicity compared to proteins lacking mannosylation. In order to gain insight into the mechanisms responsible for this observation, the present study examined the cellular uptake of the mannosylated and deglycosylated recombinant proteins.Methodology/Principal FindingsUtilizing transfected cell lines, roles for the macrophage mannose receptor (MMR, CD206) and DC-SIGN (CD209) in the recognition of the mannosylated, but not deglycosylated, antigens were demonstrated. The uptake of mannosylated antigens into murine bone marrow-derived DCs (BMDCs) was inhibited by yeast mannans (YMs), suggesting a mannose-specific C-type lectin receptor-dependent process, while the uptake of deglycosylated antigens

When and how often laboratory tests are done may depend on many factors. The timing of laboratory tests may rely on the results or completion of other tests, procedures, or treatments. Lab tests may be performed immediately in an emergency, or tests may be delayed as a condition is treated or monitored. A test may be suggested or become necessary when certain signs or symptoms appear. Due to changes in the way your body naturally functions through the course of a day, lab tests may need to be performed at a certain time of day. If you have prepared for a test by changing your food or fluid intake, lab tests may be timed in accordance with those changes. Timing of tests may be based on increased and decreased levels of medications, drugs or other substances in the body. The age or gender of the person being tested may affect when and how often a lab test is required. Chronic or progressive conditions may need ongoing monitoring through the use of lab tests. Conditions that worsen and improve may ...

What is it? The aging eye can be affected in many different ways. One of them being the formation of a cataract or clouding of the normal human crystalline lens. The other common age related change affecting the eye is called age related macular degeneration (AMD). This condition usually affects people in the 6th or 7th decade of life, but may occur in the younger population.. This condition affects the area at the back of the eye, responsible for the central part of the vision, the macula (see Eye anatomy). Degeneration, or breakdown of this part of the retina causes loss of central vision, and is one of the most common causes of legal blindness in South Africa, and the world. Most patients retain some form of peripheral vision, but overall prognosis in late / advanced AMD can be very poor.. What is DRY and WET AMD? Dry AMD is the more common form and is also referred to as atrophic or non-exudative AMD. There is formation of drusen beneath the macula that build up and eventually causes ...
Guinea pigs infected with Trichophyton mentagrophytes developed a cutaneous fungal lesion and became skin test positive to fungal antigen (trichophytin). The cutaneous fungal lesion, while thought to be a cell-mediated response, differed histologically from the skin test site. Basophils were not demonstrated in biopsies of cutaneous fungal lesions, whereas basophils were numerous in biopsies of trichophytin skin test sites. When sensitization to trichophytin was accomplished by injection of hypha in complete Freunds adjuvant instead of infecting with live fungus, basophils could not be demonstrated in skin test sites. This report demonstrated that guinea pigs could be primed for cutaneous basophilic hypersensitivity (CBH) responses by infection with live fungus.

The Candida antigen CR3-RP (complement receptor 3-related protein) is supposed to be a mimicry protein because of its ability to bind antibody directed against the α subunit of the mammalian CR3 (CD11b/CD18). This study aimed to (i) investigate the specific humoral isotypic response to immunization with CR3-RP in vivo in a rabbit animal model, and (ii) determine the role of CR3-RP in the adherence of Candida albicans in vitro using the model systems of buccal epithelial cells (BECs) and biofilm formation. The synthetic C. albicans peptide DINGGGATLPQ corresponding to 11 amino-acids of the CR3-RP sequence DINGGGATLPQALXQITGVIT, determined by N-terminal sequencing, was used for immunization of rabbits to obtain polyclonal anti-CR3-PR serum and for subsequent characterization of the humoral isotypic response of rabbits.

2. Plasma (1→3)-ß-D-glucan and fungal antigenemia in patients with candidemia, aspergillosis, and cryptococcosis.. T Miyazaki, S Kohno, K Mitsutake, S Maesaki, K Tanaka, N Ishikawa, and K Hara. Second Department of Internal Medicine, Nagasaki University School of Medicine, Japan. (1→3)-ß-D-Glucan is one of the major structural components of fungi, and it seems that it can be detected by the fractionated (1→3)-ß-D-glucan-sensitive component from a Limulus lysate, factor G. We evaluated the concentration of (1→3)-ß-D-glucan by using factor G and other fungal antigens in 24 patients with clinical evidence of mycosis and 36 healthy subjects. The mean concentration of (1→3)-ß-D-glucan in the plasma of the healthy subjects was found to be 2.7 +/- 1.9 pg/mL (range, < 6.9 pg/mL), and it was found to be substantially higher in all 11 patients with candidemia (mean, 2,207.4 pg/mL; range, 325.4 to 8,449.0 pg/mL).

In vitro studies as well as clinical trials indicate that the cytokines granulocyte-macrophage colony-stimulating factor (GM-CSF) and granulocyte colony-stimulating factor (G-CSF) enhance the ability of neutrophils (polymorphonuclear leukocytes) to eliminate microbial organisms. Toll-like receptor (TLR) proteins, homologs of the Drosophila protein Toll, have been found on the surface of mammalian cells and are important in the responses of macrophages to bacterial, viral, and fungal antigens. TLR4 is critical for the response to lipopolysaccharide (LPS) of gram-negative bacteria, while TLR2 is important for response to gram-positive bacteria, bacterial peptides, and yeast zymosan. We demonstrate that TLR2, but very little TLR4, is present on the surface of human neutrophils. In addition we demonstrate that GM-CSF and G-CSF dramatically up-regulate TLR2 and CD14 surface expression. GM-CSF treatment also up-regulates TLR2 and CD14 mRNA levels in neutrophils. In addition to increasing receptor expression,

The best pimples to pop are small whiteheads, blackheads, and pustules (looks like a whitehead, but the skin around is red and inflamed). Whiteheads appear when dead skin cells, oil, and bacteria are trapped in your pores. Blackheads are similar in that they are caused by a clogged pore, but the fundamental difference is that with whiteheads, the pore remains closed as compared to blackheads in which the pore is open. Pustules are small bumps on the skin that contain pus or fluid. The safest type to extract at home are the ones which have collected a small amount of pus or keratin in the middle and are very close to the surface of skin, and those that are not very red or deep: these are usually simple blackheads, whiteheads, or pustules, says Dr. Nazarian. Its also important to note that you should never touch deep cysts. While it may be very tempting to pop deep cysts, these should ideally be reserved to professionals as they can be difficult to treat due to the depth of the active lesion, ...
