The C group chromosomes in man cannot be distinguished solely on morphological grounds, thus, the nature of an extra C chromosome remains unknown unless it is an X chromosome, which can be identified by its late DNA-replication pattern. Extra autosomes belonging to the C group have been observed with or without mosaicism in a wide variety of blood disorders (cf, de la Chapelle et al, 1970; Hell...

A flow cytometric (FACS) detection method for Plasmodium falciparum cultures (P. falciparum) was developed using SYBR Green I and CD235A and compared against the Giemsa stained microscopic examination. The cultured P. falciparum were spiked into red blood cells (RBCs) to yield parasitemia, ranging from 0.01% to 22.0%. FACS analysis demonstrated a clear separation between P. falciparum infected ...

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...

Fig. 1. Peripheral blood (PB) smear and bone marrow (BM) aspirate findings of first case (A, B) and second case (C, D). (A) Eosinophilia (13.0×10/L) was observed in the PB (Wright-Giemsa, ×1,000). (B) Dysplastic eosinophils (sparse and mixed granules) were increased in the BM aspirate (Wright-Giemsa, ×1,000). (C) Eosinophilia (55.316×10/L) was observed in the PB (Wright-Giemsa, ×1,000). (D) The...

background: leishmaniasis is a group of diseases that are created by intracellular parasites of leishmania. cutaneous leishmaniasis is considered as one of the health problems in some provinces of iran. methods: in this study, a total of 178 giemsa-stained slides from confirmed cases of cutaneous leishmaniasis were examined. the slides were prepared from the patients with cutaneous leishmaniasi...
