Australian spiders of the genus Abstract. -Three species of the spider genus Physocyclus (P. calijbrnicus, P. enaulus. P, sp.) . SOC. 96:359-362. were karyotyped using an air-drying, Giemsa staining method. All chromosomes were metacentric, with males being 2n = 15 (N = 7 + XO) and females being 2n = 16. The karyotyping method resulted in slide preparations which were countable five years post-...

Background: Helicobacter pylori, which is associated with many upper gastrointestinal diseases, is found in half of the population of the world. Several special stains and immunohistochemistry stain for H. pylori are available. The need for and usefulness of immunohistochemical (IHC) technique has been debated for years. Toluidine blue is a simple stain for microbiological studies and is easily...

Eller, Charles (St. John's University, Jamaica, N.Y.), and William H. Beckert. Nitrogen dioxide fixation in bacterial chromatin studies. J. Bacteriol. 90:1710-1712. 1965.-Satisfactory chromatin staining was obtained with two Bacillus species when nitrogen dioxide was used for fixation in conjunction with either the acid Giemsa or Feulgen staining methods. An impression method was employed for t...

One of the most common bacterial infections that causes ophthalmia neonatorum is Chlamydia trachomatis, (C. trachomatis). Very few studies have been performed in Iran using both cell culture and polymerase chain reaction (PCR) methods to determine the prevalence of C. trachomatis as an etiological agent of ophthalmia neonatorum. This study aimed to evaluate the prevalence of neonatal chlamydial...

Sea-blue histiocytosis is a rare disorder seen in patients with lipid metabolic or ceroid storage diseases. Sea-blue histiocytes are ceroid-laden macrophages detectable by May-Giemsa staining. We report a case of a 28-year-old woman diagnosed with Niemann-Pick disease at 2 or 3 years of age. To confirm this diagnosis, we examined her bone marrow, which revealed scattered foci containing aggrega...
