ABSTRACT

Stains in microbiology lab are the first tools employed for diagnosis of infectious diseases. Stains have helped to identify the ethiology of microbial involvement for more than a century. As the wide spectrum of stains is currently in progress for the detection of bacteria, fungus and parasites, such fundamentals as the Gram stain are still considered basic for initial evaluation of bacteriological samples, while the Wright stain is used for very particular diseases as those related to parasites. Other specific tintorial methods as the Ziehl-Neelsen stain are used for diagnosis of chronic diseases such as tuberculosis oractinomycosis. The lactophenol blue stain is best employed for diagnosis of fungal infections, as it helps to identify fungi and to preserve their morphological structures. Different stains in the clinical microbiological lab are permanent basic tools for the diagnosis and treatment of many diseases of infectious ethiology.


Key words: Laboratory stains, microorganism, microbiology, Gram, Wright, Ziehl-Neelsen, lactophenol blue.
