The Isolation of Chromogenic Mycobacteria from Laryngeal Cultures

The isolation of chromogenic mycobacteria from laryngeal cultures.

It is known that the cultural characteristics of strains of Mycobacterium tuberculosis isolated from tuberculous secretions may be changed under the influence of anti-tuberculosis drugs. It has been suggested that this is due to " biological disintegration" of the bacteria (Lanyi and Eidus, 1954). The process is usually a gradual one. The present report is concerned with the isolation from lary...

Direct isolation of Candida spp. from blood cultures on the chromogenic medium CHROMagar Candida.

CHROMagar Candida is a selective and differential chromogenic medium that has been shown to be useful for identification of Candida albicans, Candida krusei, Candida tropicalis, and perhaps Candida glabrata. Colony morphology and color have been well defined when CHROMagar Candida has been used to isolate yeast directly from clinical specimens, including stool, urine, respiratory, vaginal, orop...

Isolation of Mycobactins from Various Mycobacteria

Mycobactin S has been isolated from Mycobacterium smegmati8 and from Mycobacterium sp. Olitzky & Gershon, strain 2, and mycobactin H from M. thermore8i8tible; all three organisms were grown on synthetic media of low iron content. These two mycobactins are mixtures of compounds having the same nucleus but differing in their fatty side chains. The nucleus of mycobactin S has a chemical structure ...

Isolation of genomic DNA from mycobacteria.

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
