بالنسبة لشيت العلماء اكيد ما حد مدوره او قراه بس غالبا حيكون فيه سؤال علي عالم. ..
فحاول تتذكر هاللي بنقوله
المادة لها Father اللي🧓🏼 يقولوله
Father of microbiology
واللي هو لويس باستير اذكروا عليه انه كان مهتم #بالتعقيم #والتخمر #والتطعيم
يعني حاجه فيه sterilization والا. Fermentation او Vaccine شوره
وهوا اللي نفي نظرية التوالد التلقائي disprove spontaneous generation
..............
ولو قالولك من اول من استعمل المطهرات في العمليات🚿🚿. Antiseptic surgeries
فاختار جوزيف لستر وسموه. Father of antiseptic surgrey#🧓🏼
------------------------
اما. Paul Ehrlich فكان شوره الادوية وال antitoxin. واكتشف علاج ال syphilis 💊💊💊
وهو. Father of chemotherapy
........
اما. Robert koch. 🧓🏼 فشوره الاوساط الصلبه. والصبغ ومن خلالهن اكتشف بكتيريا الانثراكس والكوليرا و عشان شغله ع البكتيريا سموه
. Father of bacteriology🧓🏼
طبعا ماتنسوا الكسندر فلمنج والبنسيلين

Structure of bacteria = 💙
Function of cell wall...
Difference between gram +ve & -ve cell wall..
Function of Teichoic acid..
why gram +ve bacteria very sensitive to action of penicillin an lysozymes?
functions of mesosome
functions of plasmid
functions of capsule
what is biofilm formation ?
what is quellung reaction
Difference between flagella & pilli
To Remember for Mcqs= 💙
adherence of gram -ve = pilli
adherence of gram +ve = teichoic acid
location of degradative enzymes = periplasmic space.
Antigen of gram +ve = Teichoic acid
Antigen of gram -ve = lipid A & specific polysaccharide (O Antigen)
cell membrane no cholesterol except = Mycoplasma
bacteria completely no cell wall = protoplast
bacteria partially removed cell wall = spheroplast
capsule is polypeptide in = Bacillus anthracis
bacteria produce large amount of slime and mucoid growth = Klebsiella
flagella = H antigen
common pilli = in +ve & -ve
sex pilli = only in -ve
Spores = only in +ve (Bacillus & Clostridia)
Sporulation process = 10hrs
Germination = 2hrs (faster)

Capsule = well organized glycalyx
Slim layer = diffuse unorganized glycalyx
Bacterial Spores outer coat = keratin like protein
- Resistant to disinfectants & Staining

Bacterial genetics = 💙
what are the replication enzymes?
function of DNA polymerase III
function of DNA polymerase I
define episome
characters of plasmid
to Remember for Mcqs = 💙
Start codon = AUG = fMet
Bacterial mRNA = polycistronic
Conjugative plasmid = common in -ve
non-conjugative = common in +ve
silent mutation = same A.A
nonsense mutation = stop codon
missense mutation = new A.A
frame shift mutation = addition or deletion single Nucleotide

Gene Transfer = 💙
Define transformation, transduction, conjugation مهمات 💙
Concept of F+ X F- mating
concept of Hfr conjugation
major vectors
Application of genetic engineering..

to Remember for Mcqs = 💙
natural transformation = E.coli
transduction = by bacteriophage
bacteria carrying prophage = lysogenic bacteria
- generalized transduction = random = bacterial DNA gets into phage accidentally (false packaging)
- Restricted transduction = specific pieces of chromosome = adjacent genetic material of bacterial chromosome get into phage
in conjugation = ssDNA transfer
F factor = conjugative plasmid = in male bacteria
Transposon = jumping gene = mobile
Transposition = no require homolgy
- Insertion transposon = smallest simplest
- composite transposon = larger
