Nocardia pathology outlines

Nocardia species have a thin layer of mycolic acid which retains the carbol fuchsin dye when using a weaker acid for decolorization (i.e. modified acid fast stain). This feature helps distinguish from other filamentous bacteria that stain negative with this procedure. Comment Here Reference: Nocardia Nocardia may be difficult to culture in clinical microbiology laboratories. Nocardia species are classically gram-positive, strictly aerobic, filamentous, branching, weakly acid-fast bacilli. They may be isolated on routine bacterial, fungal, and mycobacterial media. Colonies may appear within 4 days, but may require up to 2-4 weeks of culture

In humans, disease-causing species are mostly Nocardia asteroids.

Background Parkinson's disease (PD) is a disorder characterized by dopaminergic neuron programmed cell death.

Nocardiosis is an infectious disease caused by Nocardia species that occurs worldwide, albeit more prevalently in tropical/subtropical regions. It can appear as either acute, subacute or as a chronic infection mostly with those with a compromised/weakened immune system.

In pathology, the Grocott-Gomori's (or Gömöri) methenamine silver stain, abbreviated GMS, is a popular staining method in histology.The stain was originally named after György Gömöri, the Hungarian physician who developed the stain.. It is used widely as a screen for fungal organisms.Particularly useful in staining carbohydrates. It can be used to identify the yeast-like fungus. Bacteria can cause meningitis, encephalitis, brain abscess, and subdural empyema producing a variety of neurological signs. Bacteria are classified based on their morphology, microscopic. AIt is a copper phthalocyanine dye that is soluble in alcohol and attracted to the bases found in the lipoproteins of the myelin sheath.
