LATEST UPDATE GRADED A+
What do tRNAs do? they transfer amino acids to the ribosome for protein synthesis
ATP (adenosine triphosphate) main energy source that cells use for most of their work
Has 3 phosphate groups
examples of prokaryotes Bacteria and Archaea
Examples of eukaryotic cells Fungi, animal, plant, protist
bacteria causing acne Propionibacterium acnes
(P. acne)
causative agents of impetigo S. aureus and S. pyogenes
(S. Pyogenes also causes scarlet fever)
____ and ____ are present in the skin Lysozyme and antimicrobial peptides
contact lens infection Acanthamoeba keratitis
SSS syndrome SSS= stapholococcal Scalded Skin Syndrome
causitive agent: S. Aureus
causes bullous lesions
a form of impetigo
, Keratitis inflammation of the cornea
more serious infection of the eye than conjunctivitis
causitive agent: any microorganism after eye trauma
Dermatophyte Fungal organism that causes skin disease
mycoses strictly confined to nonliving epidermal tissue and their derivatives.
39 species
Ex: Ringworm
Top 5 skin defenses: 1.) keratinized surface
2.) sloughing
3.) low pH
4.) high salt
5.) lysozyme--enzymes found in sweat, tears, and saliva that break down peptoglycans
peptoglycan polymer that consists of sugars and amino acids that form a mesh-like layer
ouside the plasma membrane
found in cell wall of bacteria only
the amount of peptidoglycan determined by gram staining
Chicken Pox mode of transmission: droplet contact OR inhalation
Caused by: HHV-3 virus, also known as Vericella-Zoster virus
