the present study was carried out for evaluation of calcoflour white staining (cws) as a rapid method for detection of pneumocystis carinii in respiratory specimens of rats as an animal model for human infection. a total of 35 spraque – dawley rats were divided into two groups. group1 (20 rats) received increasing doses of dexamethasone subcutaneously, and group 2(15 rats)as control group that ...
BACKGROUND Mycological diagnosis of onychomycosis can be performed by direct microcopy (KOH), cultures and calcofluor white. AIMS To compare the percentage of positivity and the degree of correlation of KOH, cultures and calcofluor white for the diagnosis of onychomycosis. METHODS Descriptive, transversal and comparative study. Samples of toenails with onychomycosis were used for KOH, cultu...
Abstract Background and Objective: Microsporidia is an obligatory intracellular parasite known as an opportunistic infection in immunocompromised patients. Its laboratory diagnosis is relatively difficult and modified trichrome staining is a standard diagnostic method for detection of Microsporidia. The aim of present study was to identify intestinal Microsporidia in kidney- transplanted pat...

Background and purpose: Respiratory failures are common diseases among different populations. Pneumocystis jirovecii colonization causes respiratory failure in children and adults with AIDS and patients with predisposing factors of immunosuppression including malignancies, organ transplant, inherited immune deficiencies and immunosuppressive agents. The aim of this study was to evaluate the eff...
Microsporidia are obligate intracellular parasites, recognized as causing chronic diarrhea and systemic disease in AIDS patients, organ transplant recipients, travelers, and malnourished children. Species of microsporidia that infect humans have been detected in drinking-water sources, and methods are needed to ascertain if these microsporidia are viable and capable of causing infections. In th...
Three monoclonal antibody staining kits, from Genetic Systems, Disease Detection International, and Meridian Diagnostics, were compared with calcofluor white for the direct detection of Pneumocystis carinii in respiratory specimens. Of the 150 specimens tested, 23 were found positive for P. carinii by any of the four stains; 13 were bronchoalveolar lavage, 7 were induced sputum and 3 were expec...
