Leptospira interrogans
They serve as the energy source or food reserve of the bacteria.
Granular inclusions
Their presence is one of the important properties looked for in the identification of the organism.
Granular inclusions
Granules that are located one or both ends known as ____
Polar bodies (Yersenia pestis)
Granules which structures are glycogen, cyanophysin, granules, poly-B-hydroxybutyrate granules, carboxysomes, gas vacuoles and polyphosphate granules
Volutin or metachromic granules
Polyphosphate granules
Babes Ernst bodies (Corynebacterium diphtheriae) & Much’s granules (Mycobacterium tuberculosis)
Are exterior portion filament that rotates and thus, causes bacteria to be motile
Flagella
It is important in the survivability and pathogenic ability of bacteria
Flagella
They are hard to demonstrate because of their minuteness (0.12u)
Flagella
The easiest method to demonstrate flagella is to use ______ as a mordant and to swell bacteria under the right pH and then stain them
tannic acid
Example of a bacteria that has flagella
Proteus vulgaris
Present in some bacteria especially those belonging to the Genus Bacillus and Genus Clostridium
Bacterial spore
These structures are small, dormant structures located inside the bacterial cell
Bacterial spore
They aid in the survival of bacterial against external conditions
Bacterial spore
Bacterial spore is mainly composed of
Dipicolinic acid and Calcium ions (Calcium dipicolinate)
Since spores are very resistant to physical and chemical agents of disinfection, thus ______ procedures must consider into account
Sterilization
It helps bacteria to attached to the surface of solid objects or tissues
Glycocalyx
An organized material that is firmly attached to the cell wall.
Capsule
It serves as protection of bacteria from the attacks of human defense cell since it resists phagocytosis and desiccation
Capsule
An unorganized material that is loosely attached to the cell wall. It can either inhibit phagocytosis and aid in the adherence of bacteria to surfaces
Slime layer
