Leifson stain was modified to produce rapid staining of bacterial flagella on untreated microscope slides. The procedure was reliable when tested against a variety of motile and nonmotile bacteria.
Little did Christian Gram1 know that his differential staining technique developed in 1884 would remain one of the first procedures learned by beginning bacteriology students and one of the first procedures carried out in any laboratory where bacteria are routinely identified at the end of the 20th century. In today's high-tech medical world where the utilization of nucleic-acid amplification i...
INTRODUCTION Campylobacter species are recognized as a major cause of acute gastroenteritis in humans throughout the world. The diagnosis is mainly based on stool culture. This study was done to evaluate the effectiveness of staining methods (Gram stain using 0.3% carbol fuchsin as counter stain and 1% carbol fuchsin direct stain) versus culture as the gold standard. METHODS A total of 300 ch...
Short-tandem repeat (STR) allelic intensities were collected from more than 60 forensic laboratories for a suite of seven samples as part of the National Institute of Standards and Technology-coordinated 2001 Mixed Stain Study 3 (MSS3). These interlaboratory challenge data illuminate the relative importance of intrinsic and user-determined factors affecting the locus-to-locus balance of signal ...
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, ...
An evaluation of the standardized Romanowsky stain of Marshall et al. has been made in a routine haematology laboratory. It was noted that this stain had several advantages over the May-GrUnwald Giemsa stain used in most British laboratories. These advantages include ease and speed of preparation, a shorter staining time, and reproducibility of results. These results are described in detail. Th...
