Capsules Flashcards
Capsule, quelling reaction, capsule and immunology, capsular vaccine, glycocalyx, pili and fimbria, plasmids, ribosomes
Define capsule and its function
Sticky gelatinous layer
security by bacteria
helps to attach host cells
protect against phagocytosis
What’s the exception of capsule
Bacillus anthracis
Right encapsulated bacteria
Strep pneumoniae hemo influenza neisseria meningitidis e-coli salmonella Klebsiella Group B strep
How to fight our immunity the capsule bacteria
B cells secrete capsular antibodies IgG
antibodies bind capsule
phagocytosis consume bacteria
via FC receptors
Mention capsule vaccine
Neisseria meningitidis
streptococcus pneumoniae
haemophilus influenza type b
Mention glycocalyx and which bacteria use
Is a sugar coat made up polysaccharide
use it to adherence to the surface
streptococcus epidermis
Define plus meatus and it’s function
Small DNA molecular within a cell physically separated from chromosomal DNA
can replicate
contain genes
can be transferred from one bacteria to another
Discuss the ribosomes of bacteria
Site of protein synthesis in bacteria
two subunits 50s and 30s
Components of Spore and list Spore forming bacteria
Goat outermost layer karatein like protein Cortex/ corel wall innermost layer Peptidoglycans
Spore forming bacteria
Bacillus anthracis bacillus cereus clostridium perfringens clostridium tetani clostridium botulinum
