Mycoplasmas
Mycoplasmas e A group of the smallest organisms that can be free living in nature Pass bacterial filter and also grow on laboratory media. More than 80 species, belong to Mycoplasmatales of mollicute. 3 families can be divided: Mycoplasmataceae(require external cholesterol during growth, contain Mycoplasma and ureplasma two genera); Acholeplasmataceae(need not external cholesterol during growth); Spiroplasmataceae (can form spiral structure)

Morphology Morphology e The smallest among prokaryotic microganisms with circular dsDNA, usually 0.2-0.3um in size lack of cell wall e Pleomorphic, spherical, short rod, filament; Gram /negative, but stained hardly, usually use Giemsa stain They can assume multiple shapes including round, fried eggcolonial pear shaped and even filamentous morphology
BOLOGALFEATURES Motility: Motile by possible release and reattachment of terminal cell organelle, no flagella present; possess a protein attachment factor termed p 1 that interacts with a specific cellular receptor and allows adherence to respiratory epithelium Respiration-Fermentation Aerobes anaerobes
