DEACON, Peacock, Freeman, and Harris (1959) showed that the fluorescent antibody (FA) staining technique can be used to demonstrate Neisseria gonorrhoeae in specimens of secretion taken from patients suffering from gonorrhoea. Since then this technique has been widely employed for research but has been less popular for routine use as it is expensive and timeconsuming. Gallwey, Nicol, and Ridley...

Cyclospora cayetanensis is a cause of prolonged diarrhoea, mainly in travellers. Laboratory diagnosis may be achieved by a number of methods such as the staining of faecal smears by the modified Ziehl-Neelsen (ZN) technique. Safer methods using this technique have been described for the staining of acid fast bacilli and cryptosporidia by replacing the phenol content of the carbol fuschin stain ...

Aloe barbadensis miller (Aloe vera) aside being a potent antioxidant with effects attributed to the phytoconstituents (anthraquinone), can also serve as natural dyes. This study explored staining potentials of A. extract on microbial specimens in modified Gram’s technique. The plant was washed; shrubby edges leaves were scraped off and each leaf cut open expel gel content. dried grinded materia...

Sixty carcinoid tumours were tested in a retrospective study with an immunoperoxidase technique using a monoclonal antibody against serotonin immunoreactive sites, with argyrophil staining using the Grimelius technique, and with argentaffin staining using the Masson-Fontana technique. A good correlation between all three techniques in the diagnosis of ileal carcinoid tumour was found, but the i...
