Dark blue - staining distemper virus inclusion body within the cytoplasm of a neutrophil (at the 2 o ’ clock position) of an unvaccinated dog with acute distemper; slide was stained with a commercial Diff - Quik stain (recommended) to elucidate inclusion bodies.
Examination of peripheral blood smears or exfoliative cytology (e.g., conjunctival scrapings) for intracellular distemper inclusion bodies is highly diagnostic, particularly in the early stages of infection.

Microvilli
Microvilli are microscopic cellular membrane protrusions that increase the surface area of cells, and are involved in a wide variety of functions, including absorption, secretion, cellular adhesion, and mechanotransduction. These finger-like projections from the small intestine are also home to huge numbers of microbes.

Streptomyces species bacterium in an agar plate

Streptomyces species are found worldwide in soil and are important in soil ecology. Much of the characteristic earthy smell of soils arises from chemicals called geosmens given off by Streptomyces species. Streptomycetes are metabolically diverse and can “eat” almost anything, including sugars, alcohols, amino acids, organic acids, and aromatic compounds. They have unique abilities in their production of numerous antibiotics. There is considerable interest in these organisms as agents for bioremediation.
