UV light & Amicrine dye
cause bacteria to lose their plasmids
BCYE (buffered charcoal yeast extract) agar
used for isolation of legionella pneumophila (cause of Legionnaire's disease)
Protective antigen of B. anthracis encoded by
plasmid
Organisms w/ plasmid mediated pathogenicity determinants
Enterotoxigenic E. Coli
E. coli
Shigella
Yersinia
B. Anthracis
Clostridium tetani
Staphylococcus aureus
Heat Labile enterotoxin action
activate adenylate cyclase in small bowel epithelial cells leadin to diarrhea
Heat Stabile enterotoxin action
activate guanyl cyclase in small bowel epithelial cells leading to diarrhea
Site specific recombination
Transposons
Restriction endonucleases
are palindromes, that is, they read the same in both directions

role is to protect the microorganism in which they are found from any invadin DNA from another species

DNA from the host is prtected b/c it has been modified by a specific methylase
BamH1

EcoR1

PvuII

Sau3A

Alu 1
restriction endonucleases
Fat loving yeast
Malassezia (Pityrosporon) furfur- cause of liver spots
Contagious fungi
dermatophytes
green fluorescence under Woods lamp
Microsporum
Saubouraud's medium
used to isolate fungi

microsporum: thick walled macroconidia

Trichophyton: macroconidia

Epidermophyton floccosum: thin walled macroconidia produced in banana bunches on agar
Cauliflower lesion
Chromoblastomycosis
Glucose peptone agar (w/ chloromycetin)
used to isolate causative agents of chromoblatomycosis:

Fonsecaea pedrosoi
Fonsecaea compacta
Cladosporium carrionii
Phialophora verrucosa
Madura foot
an early synonym for mycetoma
Grains
variously shaped bodies whicha are found embedded in the pathological tissue or in the discharge of a mycetoma (tumor caused by fungi or actinomycetes)
Skin w/ crackling consistency
called crepitus

occurs in gas gangrene caused by Clostridium perfringens
Infant Botulism vs. Adult Botulism
Infant Botulism: contracted by ingesting spores of C. botulinum

Adult Botulism: contracted by ingesting preformed neurotoxin of C. botulinum
Bacteriocin
kill bacteria of the same species that do not contain the plasmid coding for the bacteriocin
Toxins w/ ADP ribosylating activity
Cholera toxin
E. coli heat labile toxin
Diphtheria toxin
Pertussis toxin
Unpasteurized apple cider ingestion causes?
infection by campylobacter jejuni
Toxoids
exotoxins can be made into toxoids, but endotoxins can not
Diphtheria toxin
blocks protein synthesis by inactivating elongation factor(EF2), which is involved in translation of eukaryotic mRNA into proteins
Types of protein secretion
Type I: export small molecules

Type II: general secretory pathway

Type III: important in the delivery of toxins to eukaryotic cells

Type IV: allow for secretion of self-assembling cellular structures (e.g. pilin), DNA, toxins
Onychomycosis
infection of the toenails
Mulberry colonies
Mycoplasma pneumoniae
P1 Protein
protein adhesin that binds Mycoplasm pneumoniae to sialic acid receptor on host cell
