A total of 60 HIV infected patients complaining of dry cough for at least two weeks and attending the Out-patient Department of the Specialist Hospital, Waibargi, were screened for Pneumocystis carinii. Induced sputum samples were examined with Giemsa and Gomori silver methenamine stains. P. carinii were detected in 18 patients (30%) with silver stain and 13 patients (21.7%) with Giemsa stain. ...

HeLa 229 cells were infected with genital tract strains of Chlamydia trachomatis. After incubation for varying times the infected cells were fixed and stained with the fluorescent DNA binding dyes Hoechst 33258 or DAPI for comparison with conventional Giemsa stain. Fluorochrome-treated preparations were examined by incident ultraviolet fluorescence microscopy and the Giemsa-stained preparations...

BACKGROUND Stereology is the study of estimating geometric quantities. When successfully applied, the combination of immunohistochemistry (IHC) and stereology eliminates intra- and interobserver variability for cell type identification. METHODOLOGY/PRINCIPAL FINDINGS We propose a method to validate existing antibody based cell type markers for stereological application. Comparison was made on...

Figure 1. A) Bone marrow aspirate showing numerous Histoplasma capsulatum inside the osteoclastic giant cell and macrophage (inset) (Giemsa, 100 x), B) bone marrow biopsy showing Histoplasma (H&E, 100 x), C) PAS staining showed yeast-like cells with bright eosinophilic structures, D) GMS staining showed clusters of fungal yeasts.

The objectives of this study were to conduct a prevalence survey of trichomoniasis in pregnant women and to evaluate the utility of different methods for its diagnosis. A total of 597 vaginal exudates from pregnant women who were examined at the Hospital de Clinicas in Buenos Aires, Argentina from 1 August 2005 to 31 January 2007, were prospectively and consecutively evaluated. The investigatio...

A sequential silver-Giemsa (SG) procedure is presented, initially to stain the p11 and q11 euchromatic bands and subsequently the q12 heterochromatic band of the human Y chromosomes. A three sub-band division of the q11 band can be identified. The same technique differentially stains the secondary constriction of chromosome 9 as well as most other satellite III DNA regions of the human karyotype.

so in the case of very minute flagellates. Shortt (1923) fixed wet films of flagellates by exposing the film to the vapour of 4 per cent osmic acid solution and subsequently stained the dry film with Giemsa after the manner of blood films. This method produces excellent results, and the flagellates, however minute, stand out very clearly. This method, however, involves the use of an expensive m...

A four-generation transmission of 1qh+ chromosome was ascertained by routine chromosome analysis of a mildly dysmorphic and retarded 61/2-year-old female. Concordance between synophrys and the 1qh+ marker was the only consistent phenotypic relationship. The variant chromosome did not appear uncoiled, and Giemsa centromeric staining (C-bands) revealed an increased width of the heterochromatin co...
