13. Q-4
⢠Which among the following
statements is true?
⢠A. Fungi are eukaryotes
⢠B. viruses have cell wall
⢠C. Bacteria have nucleus
⢠D. Parasites are prokaryotes
14. Classification of
Microorganisms
⢠Classification by structure
⢠Subcellular â DNA or RNA surrounded by
a protein coat â viruses
⢠Prokaryotic â simple cell structure with
no nucleus or organelles â bacteria
⢠Eukaryotic â complex cell structure with
nucleus and specialized organelles â
protozoans, fungi, parasites
15. ⢠Protozoans â single celled
eukaryotes
⢠Fungi â multicelled eukaryotes
with cell wall
⢠Parasites â multicelled
eukaryotes without cell wall
20. Protozoans
⢠Single-celled eukaryotic organisms,
larger than bacteria
⢠Found in soil and water
⢠Illnesses
⢠Malaria
⢠Amebic dysentery
⢠Trichomoniasis vaginitis
⢠Leading cause of death in developing
countries
21. Q-6
⢠What is the type of culture seen
in next picture used for?
25. Q-7
⢠What is the unit of
measurement of a bacterium
cell wall?
⢠A. meter
⢠B. Nanometer
⢠C. Micrometer
⢠D. centimeter
26.
27. Size of Bacteria
⢠Unit of measurement in bacteriology
is the micron (micrometre, Âľm)
⢠1 micrometre (10-6)= 1/1000 mm =
1/10000 cm = 1/100000 metre
⢠1 nanometer (10-9)= 1/1000
micrometer = 1/100000000 meter
⢠Bacteria of medical importance
⢠0.2 â 1.5 Âľm in diameter
⢠3 â 5 Âľm in length
34. Consequences of Binary
Fission
⢠Very large number of cells very
fast
⢠Mathematical progressions
⢠arithmetic
(1>2>4>6>8>10>12>14>16)
⢠geometric(1>2>4>8>16)
⢠exponential expression (20 > 21 > 22
>23>24)
⢠logarithmic expression(0
>log21>log22>log23>log24)
35. Q-9
⢠During which phase of bacterial
growth curve, is the growth
fastest?
⢠A. Lag phase
⢠B. Log phase
⢠C. Death phase
⢠D. Stationary phase
37. Final questionâŚThank
God!
⢠Which type of liquid culture
medium contains an inhibitory
substance added to it?
⢠A. Enriched Media
⢠B. Enrichment Media
⢠C. Selective Media
⢠D. Indicator Media
38. Enriched media
⢠Substances like blood, serum, egg
are added to the basal medium.
⢠Used to grow bacteria that are
exacting in their nutritional
needs.
⢠Eg: Blood agar, Chocolate agar
40. Enrichment media
⢠Liquid media used to
isolate pathogens from a
mixed culture.
⢠Media is incorporated
with inhibitory
substances to suppress
the unwanted organism.
⢠Eg:
⢠Selenite F Broth â for the
isolation of Salmonella,
Shigella
⢠Alkaline Peptone Water â
41. Selective media
⢠The inhibitory substance is added
to a solid media.
Eg:
⢠Mac Conkeyâs medium for gram
negative bacteria
⢠TCBS â for V.cholerae
⢠LJ medium â M.tuberculosis
⢠Wilson and Blair medium â S.typhi
⢠Potassium tellurite medium â
Diphtheria bacilli
44. Indicator media
⢠These media contain an indicator
which changes its colour when a
bacterium grows in them.
⢠Eg:
⢠Blood agar
⢠Mac Conkeyâs medium
⢠Christensenâs urease medium
