  7. Famous microbiologist In immunology • Louis Pasteur (1822 -1895). Emil von (1901) Paul Ehrlich in 1912Margaret Pittman (1901-1995)Gerhard J Domagk (1935) Alexander Fleming (1928) William A Hinton (1883-1959Albert Shatz, E Bugie and Selman (1944PLANTS & SOILSergei Winogradsky, in 1890, in soil. • )

  8. General Microbiology • تعریف : میکروارگانیسم ها باچشم غیرمسلح دیده نمی شوند • دلیل نیاز به طبقه بندی • اولین طبقه بندی موجودات زنده • طبقه بندي ميكروارگانيسمها: • براساس ساختارهسته:Acaryotes Prokaryotes Eukaryotes

  9. General Microbiology • طبقه بندي براساس سايز سلولي و نحوه ي تغذيه • Viruses • Bacteria • Fungi • Algae • Protozoa

  10. Bacterial Numenclature • Binomial nomenclature • Genus + Species • Example: Escherichia coli • Bacillus cereus • B. cereus

  11. General Microbiology • Bacteria • Shape • Coccus • Rod • Spirillum • Bacteria • طول 1-10 ميكرومتر • عرض 0.5-1 ميكرومتر

  12. General Microbiology • Bacteria • Arrangment

  13. Bacteria colony تعریف : اجتماعی از سلولهای میکروبی که از یک سلول والد برروی محیط جامد (Agar media) به وجود میایند رشد باکتری در محیط مایع (Broth) باعث کدورت محیط میشود.
