types of cells in a pharyngeal specimen
The tissue in the pharynx include:
Stratified squamous epithelium &amp; mucus-producing glands.
However other cells that could be found would be other types of bacterial, is this what you're referencing?
Commonly scientists start with a gram stain to determine the classify the bacteria.
Gram+ bacteria have cell walls composed of thick layers of peptidoglycan. Gram+ cells stain purple when. Gram- bacteria have cell walls with a thin layer of peptidoglycan. Gram- bacteria stain pink.
The microbiome of a human consists of 100,000 billion bacteria. Therefore there are many types. E.g. Prevotella has been shown to be the most common type of bacteria in the human pharynx.
In a pharyngeal smear you would expect to find Stratified squamous epithelium, mucus-producing glands, bacteria and if a virus is present. Viral particles. This can be determined by RNA or DNA analysis.
E.g. COVID-19 is an RNA virus. If PCR analysis was completed on a sample obtained from a pharyngeal smear then we could confirm the presence of the aforementioned mammalian cells, bacteria and viral genetic material.
