UNIT 4 Flashcards
Groups of bacteria that retain SINGLE SHAPE
Monomorphic
Charac of bacteria
Absence of organelles
Unbound dna
Cell wall - peptidoglycan
Assume MANY shapes
Pleomorphic
Cocci: Single Pairs Clusters Chain Four Eight
Mono Diplo Staphylo Strepto Gaffkya tetrads Sarcinae
Bacilli: Pairs Chain Palisades Like cocci Long and filamentous
Diplo Strepto Corynes Coccobacilli Fusobacteria
Short thick
Belong to vibrionaceae family
1 or 2 curves & flagella
Rigid spirilla
Long thin
Spirocheteceae family
Periplasmic or axial filaments
Flexible
Spirochetes:flexible spirilla:
W straight ends-
Hooked ends-
Long deep curves-
Treponema
Leptospira
Borrelia
Only type of bacteria without a cell wall
Mycoplasma
Exhibits filamentous growths
Actinomyces
Nocardia
Streptomyces
Exhibits infectious agents: intracellular parasites
Rickettsia
Chlamydia
Facilitate attachment of capsules on host tissues
Fimbriae
Increase resistance against microbial control agents
Bacterial endospore
Acts as vehicle for transferring virulence to another bacteria
Pili
Popular technique to distinguish type of bacterial cell wall
Gram staining
