Enumeration of mycoplasmas after acridine orange staining

Staining with an Acridine Orange Derivative for the Detection of Mycoplasmas in Cell Cultures

• Fischer 0., Dagmar Zendulkova: Staining With an Acridine Orange Derivative for the Detection of Mycoplasmas in Cell Cultures. Acta vet. Brno, 62,1993: 49-53. 24 cell cultures were examined for the presence of mycoplasmas by fluorescence methods using 3-amino-6-methoxy-9-(2-hydroxyethylamino) acridine (AMHA) or bisbenzimide 33258 (Hoechst), and by culture in liquid media containing glucose or ...

Histochemical observations on Mycoplasma after staining with acridine orange.

Mycoplasma colonies and Mycoplasma cells in preparations from infected milk and lymph nodes were observed for their fluorescent qualities after treatment with acridine orange. Mycoplasma colonies fluoresced brilliant red or red-orange. When treated after exposure to ribonuclease, the colonies fluoresced lime-green. There was no fluorescence when both ribonucleic acid and deoxyribonucleic acid w...

Acridine orange staining for rapid diagnosis of Acanthamoeba keratitis.

Acanthamoeba keratitis is uncommon, but one of the most severe infectious diseases of the cornea. Delayed diagnosis or misdiagnosis as bacterial or herpes simplex keratitis leads to extensive corneal inflammation and profound visual loss. Therefore, accurate and rapid diagnosis of Acanthamoeba keratitis is essential for successful treatment and good prognosis. We evaluated the usefulness of acr...

Ratiometric analysis of Acridine Orange staining in the study of acidic organelles and autophagy.

Acridine Orange is a cell-permeable green fluorophore that can be protonated and trapped in acidic vesicular organelles (AVOs). Its metachromatic shift to red fluorescence is concentration-dependent and, therefore, Acridine Orange fluoresces red in AVOs, such as autolysosomes. This makes Acridine Orange staining a quick, accessible and reliable method to assess the volume of AVOs, which increas...
