Kapalan General Microbiology Chapter Flashcards
Is the mRNA if the virus is poly or mono ciatronic
It is polycistronic
Is the mRNA of the bacteria is poly or mono cistronic
It is both
What is the mRNA of the fungi and parasites
It is monocistronic
What does mono and polycistronic mRNA means
The monocistronic mRNA can produce one protein
But polycistronic mRNA can produce more than one protein
What ia so special about the mycoplasma bacteria
It doesn’t have a cell membrane so piptidoglycan so any antibiotic that attaches the piptidoglycan can’t work like pinacilin
Is it possible that the normal flora to cause disease
Yes if it misplaced like fecal bacteria in the urinary tract
Does the blood and the organs have any normal flora
No they are sterile
What is the most common bacteria in the skin
S.epidermis
What is the most common nose bacteria normal one
S.aureus it means golden
What is the name of the most common bacteria in the oropharynx
Viridans . Streptococci يعني اخضر متل فطريات التم
What does the IgA protease do and where it is located?
It helps the bacteria to adhesive by breaking down IgA which is the mucosal defines line so it exists in the mucosal pathogens
What is so special about the biofilms bacteria
It is like a crowd in a rock concert they eat together and protect each other from the immune system
What is the mnemonic for the anti-phagocytic bacteria (having a capsules in this case)
Some Killer Have Pretty Nice Capsules
Streptococcus pneumoniae Klebsiella pneumoniae Haemophilus influenzae Pseudomonas aeruginosa Neisseria meningitidis Cryptococcus neoformans
What does the invasins do
They are a surface proteins that allow the pathogen agent to get in the nonphagocytic cells
How doea the Rheumatic faver cause the cardaditis
By cross reaction between the antibodies and the heart
What does the piptidoglycan teichoic acid do to thr neurophils
They release toxins when they are dead to kill the neurohphils
What is the toxic part in the endotoxin
The LPS
Lipoprotein saccharide
Where does the endotoxin has in which gram bacteria
Gram negative
A pt came to the ER with septic shock and the tests showed a gram negative bacteria what is hiw virulence factor
It is LPS
What are the major 5 groups of the exotoxins
1-proteins synthesis inhibitors 2-cAMP inducers 3-neurotoxin 4-cytolysis 5-supra antigens
What are the examples of the proteins synthesis inhibors
Mnemonic سيبيه
Corynebacterium diphtheriae
Pseudomonas aeruginosa
Shigella dysenteriae
Enterohemorrhagic E. coli
What is the lag phase
It is the phase when the bacteria prepares itself to the replication
When are the antibotics most effective
In the log phase
What are the suprantigene exotoxins
Mnemonic I WILL pa u supra
Streptococcus pyogenes
Staphylococcus aureus
What is the bacteria that the breastfeeding baby has it in his colon
Mnemonic bidiphly
Bifidobacterium
What is the most important bacteria in the adult colon
Bacteroides
What is the name of the bacteria that require oxygen and don’t have another pathway
Obligate aerobes
What are the most common obligate aerobes and do they release
Mnemonic
My Parents are full of oxygen
Mycobacterium
Pseudomonas bacillus
They release enzymes called superoxide dismutase
That turn THE FREE RADICALS to O
What are the micro aerobic bacteria
هوليكابتير لأنو الهوا بالسما قليل بس بنحتاجو
Compylobactor
Helicobator
What are the obligate anaerobes
ABC
Actinomyce
Bacteroides
Clostridium
What are the bacteria that are fast acid
Acid
MY
NO
who ever drinks acid is a MAN
Mycobacterium
Nocardia is partially
All other bacteria are non fast acid
What are the positive and negative bacteria cocci and rods
شوف الصور
