Mycoplasma vs L-form

This question is asked sometime as short-note and very difficult to find so I have collected info and made this…..

Mycoplasma: Mycoplasma is a genus of bacteria that lack a cell wall around their cell membrane.

Mycoplasma

L-form of Bacteria

Due to absence of cell wall

Due to loss of cell wall, bacteria becomes l-form

Biochemical and antigenic property of its own

Retains parent bacterial properties

filterable

Non- filterable

Minimum reproductive unit 125-250nm

Minimum reproductive unit 600nm (larger)

Sterols are required for growth

Not required

Pathogenic

Nonpathogenic

Eg. - Streptococcus

L-form: L-form bacteria, also known as L-phase bacteria, L-phase variants, and cell wall-deficient (CWD) bacteria, are strains of bacteria that lack cell walls.

Differential Diagnosis of Chronic Watery Diarrhea

Chronic Watery Diarrhea can be subdivided in: osmotic, secretory and functional. Secretory Diarrhea:: bowel secretes too much fluid  VERY HIGH volume stools (>1L) Stool Osmolar Gap less than 50. No changes on Fasting. Caused by enterotoxins, bile acids(when ileal resection), carcinoid sx, VIPoma. Osmotic Diarrhea::   Non absorbable solutes that stay in bowel and drag water in its SMALLER volume stools. (<1L) Stool Osmolar Gap more than 50. Stops on fasting. ex. lactose intolerance and celiac disease Functional Diarrhea::   IBS, where hallmark is hypermotility,  has smaller volume and symptoms disappear at night.
