Monoclonal immunofluorescence compared with silver stain for investigating Pneumocystis carinii pneumonia.
نویسندگان
چکیده
Two hundred and eighty two specimens from 220 patients positive for HIV with respiratory tract symptoms, or febrile illness, or both, were examined for the presence of Pneumocystis carinii. Specimens were either induced sputum samples or bronchoalveolar lavage fluids. To establish the optimal method for laboratory diagnosis a comparison was made of detection of the organism by use of monoclonal antibody and immunofluorescence with conventional silver staining methods. Three commercially available reagents for immunofluorescence were also compared. Immunofluorescence was significantly more sensitive than the silver stain and the best results for immunofluorescence were obtained using. Northumbria Biologicals Ltd reagents.

Background & Aims: Pneumocystis carinii is an opportunist extracellular microorganism. The body can defend itself against it in natural conditions. But it can cause an infection in immunodificient conditions such as HIV, Hodgkins and other immunosuppressed diseases. The aim of this study was to apply a comparison of different staining methods such as Methenamine silver, Giemsa, Gram - Weigert, ...
متن کاملPneumocystis carinii pneumonia: detection of parasites in sputum and bronchoalveolar lavage fluid by monoclonal antibodies.
Diagnosis of pneumocystis pneumonia is based on identifying Pneumocystis carinii cytochemically in material from the lung. The silver methenamine staining methods most commonly used are technically difficult and lack specificity. The diagnostic value of immunocytological identification of the parasite was evaluated by using mouse monoclonal antibody 3F6, specific for human pneumocystis, to iden...
متن کاملApplication of immunoblotting to detect soluble Pneumocystis carinii antigen(s) in bronchoalveolar lavage of patients with Pneumocystis pneumonia and AIDS.
The technique of immunoblotting for detecting soluble Pneumocystis carinii antigen(s) in bronchoalveolar lavage fluid specimens from patients with AIDS and Pneumocystis pneumonia was evaluated. A soluble 67 kilodalton polypeptide that was immunoreactive with an anti-P carinii monoclonal antibody (2G2) was found in the supernatants of 26 lavage samples from patients with pneumocystosis. Intact o...
متن کاملComparison of four methods for rapid detection of Pneumocystis carinii in respiratory specimens.
Four stains for the detection of Pneumocystis carinii in respiratory specimens were compared for sensitivity, specificity, preparation time, and ease of interpretation. One hundred specimens were collected. Of these, 50 were induced sputum specimens and 50 were bronchoalveolar lavage fluid. All specimens were stained with Diff-Quik (DQ) (a modified Giemsa stain), a quick silver stain, and direc...

OBJECTIVE To assess the sensitivity, specificity and accuracy of Diff-Quik, fungifluor stain, the direct immunofluorescence test (DIFT) and the polymerase chain reaction (PCR) in the diagnosis of Pneumocystis carinii pneumonia (PCP) in human immunodeficiency virus (HIV)-infected patients. STUDY DESIGN From December 1992 through November 1993, 112 bronchoalveolar lavage fluid (BALF) samples we...
