A comparison of the contrast stains, Chicago blue, chlorazole black, and Parker ink, for the rapid diagnosis of skin and nail infections.
Int. J. Dermatol. 51(8) , 935-8, (2012) The cheapest, most rapid method for the diagnosis of mycotic skin and nail infections is direct examination of samples using a KOH preparation. The standard KOH wet mount lacks a color contrast. Various contrast dyes are available. Parker ink is one which has... |

Larval development of the pedunculate barnacles Octolasmis angulata Aurivillius 1894 and Octolasmis cor Aurivillius 1892 (Cirripedia: Thoracica: Poecilasmatidae) from the gills of the mud crab, Scylla tranquebarica Fabricius, 1798.
Arthropod Struct. Dev. 44 , 253-79, (2015) Detailed studies of larval development of Octolasmis angulata and Octolasmis cor are pivotal in understanding the larval morphological evolution as well as enhancing the functional ecology. Six planktotrophic naupliar stages and one non-feeding cyprid stage a... |

Growth, occurrence and development of septa in Plasmopara viticola and other members of the Peronosporaceae using light- and epifluorescence-microscopy.
Mycol. Res. 109(Pt 5) , 640-8, (2005) Although Plasmopara viticola causes grape downy mildew in most, if not all, wine producing countries, many basic biological or chemical aspects are still unknown and thus the histopathological changes during development of this oomycete pathogen were studied.... |

Kinetics of decolourisation and biotransformation of direct black 38 by C. hominis and P. stutzeri.
Appl. Microbiol. Biotechnol. 74(5) , 1145-52, (2007) In the present study, a consortium of Cardiobacterium hominis and Pseudomonas stutzeri was isolated from an effluent treatment plant of a textile industry, based on its ability to decolourise azo dyes including direct black 38 (DB38), a benzidine-based azo dy... |

Use of chlorazol black E mounts of corneal scrapes for diagnosis of filamentous fungal keratitis.
Am. J. Ophthalmol. 145(6) , 971-976, (2008) To determine whether chlorazol black E, a chitin-specific stain, can be used to detect fungal filaments in corneal scrapings and to compare its sensitivity as a diagnostic aid for fungal keratitis with that of gram and lactophenol cotton blue stains.Prospecti... |

Modifications of Kohn's chlorazol black E staining and Wheatley's trichrome staining for temporary wet mount and permanent preparation of Entamoeba histolytica.
J. Parasitol. 87(3) , 701-4, (2001) Preparation of stained smears of Entamoeba histolytica has several drawbacks. We therefore tried to simplify the staining procedures by modifing Kohn's chlorazol black E staining and Wheatley's trichrome staining techniques. Trophozoites and cysts of axenical... |
