Contrast Stain for Gonococci and Meningococci

Mutation of gonococci and meningococci in vitro to rifampin (rifampicin) resistance.

Genomic analysis of urogenital and rectal Neisseria meningitidis isolates reveals encapsulated hyperinvasive meningococci and coincident multidrug-resistant gonococci

OBJECTIVE Invasive meningococcal disease (IMD) outbreaks in men who have sex with men (MSM) have been associated with meningococcal colonisation of the urethra and rectum, but little is known about this colonisation or co-colonisation with the closely related gonococcus. Whole genome sequencing (WGS) was employed to explore these phenomena. METHODS Meningococci isolated from the urogenital tr...

Silicone Softeners for Stain Repellent and Stain Release Fabric Finishing

During the last few years the use of fluorochemicals to provide stain repellency and/or stain release properties to apparel goods has rapidly grown. The use of fluorochemicals as well as durable press resins, however, has a detrimental effect on the fabric softness. Providing premium softness is key to satisfy the highly demanding aesthetic requirements of many of today’s apparel products. Alth...

New contrast stain for the rapid diagnosis of dermatophytic and candidal dermatomycoses.

Methods. Skin scrapings were taken from outpatients with superficial dermatomycoses and cultured in Sabouraud dextrose agar with cycloheximide. They were then evaluated under a microscope using both the KOH wet mount technique and the new contrast stain. Two investigators read the slides together but were blinded to all other test results. The new contrast stain contains 1% Chicago sky blue 6B ...

Chimpanzee urethral meningococci.

SIR-Reports on the isolation of Neisseria meningitidis from the cervix (Keys, Hecht, and Chow, 1971), and from the male urethra (Carpenter and Charles, 1942; Volk and Kraus, 1973; Holmes, 1972; Wende, 1972) raise questions as to the source of the meningococci and their isolation from the genital tract. We have recently recorded an observation relating to this subject in chimpanzees. Our laborat...
