In the 6 years since Kass1firmly reintroduced the concept of counting bacteria in the urine,2physicians have become increasingly aware of the wide prevalence of urinary tract infections.1,3-5In addition, with the use of the quantitative ... CM Martin - 《Archives of Internal Medicine》 被引...
Likewise, a gram-negative rod in a patient receiving an extendedspectrum penicillin would suggest a resistant coliform. The Gram's stain remains the cornerstone of rapid detection of intraamniotic infection in women with intact membranes and premature labor. 3'4 It has become the method of choice...
The nonfermenting gram-negative bacteria are a group of aerobic, non–spore-forming bacilli that either do not use carbohydrates as a source of energy or degrade them through metabolic pathways other than fermentation.10,21 Unlike the Enterobacteriaceae, the nonfermenting gram-negative ...
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 ...

The Brown-Hopps stain is currently the preparation of choice, because it enhances gram-negative bacteria and rickettsia to a greater degree than the Brown-Brenn. In addition, the latter can be hazardous to technical personnel and has largely fallen into disfavor. The tissue Gram stain colors ...
Color — typically bacteria may be either “Gram positive” (purple) or “Gram negative” (pink) Shape — the most common shapes include round (cocci) or rod-shaped (bacilli) Additional information may be obtained by observing the groupings of the bacteria on the slide, such as cocci that...
α-hemolysin (HLY) from Escherichia coli (E. coli) is one of extra cellular toxines belonging to RTX families from gram negative bacteriaceae. We report the effect of HLY from E. coli on the human polymorphonucler leukocyte (hPML) function. Methods HLY was extracted from a strain isolated...
