25
Cell walls are made up of few layers of peptidoglycans and an outer membrane. Outer layer are made up of Lipopolysssacharides, lipoprotiens, and phospholipids.
Gram Negative
26
Also known as ancient bacteria, All are unicellular, Most don’t need oxygen
Archaea
27
Some are unicellular, Some are filamentous
Fungi
28
aggregate of hyphae
Mycelium
29
The most common method of asexual reproduction of fungi is through _______________
spore production.
30
a hypha that can fragment to form cells that behave as a spores.
Arthrospore
31
if cells are surrounded by a thick wall before separation they are called chlamydospores
chlamydospores
32
if the spores develop within a sac.
Sporangiospores
33
the spores are not enclosed in a sac but produced at the tips or the sides of the hypha.
Conidiospores
34
produces from a vegetative mother cell by budding.
Blastospores
35
Proto-_____ Zoa-______
first, animal.
36
They are eukaryotic organisms that consist of one cell.
Protozoans
37
-for digestion and an osmoregulator
Endoplasm-
38
They have few ciliates.
Morphology of protozoans
39
by binary fusion
ASEXUAL
40
by conjugation
SEXUAL-
41
In latin it means venom or poison, Capable of replication within the living cells of bacteria, animals and plants.
Virus
42
Double Stranded, Type of sugar-deoxyribose
DNA VIRUS
43
Single Stranded, Type of sugar-Ribose
RNA VIRUS
44
is also known as the protein coat that encloses and protects the nucleic acids.
Capsid-
45
are those found living inside their hosts. Though some of these spend a portion of their life in water or soil, their mature forms live within animal hosts and are often highly adapted to this specialized environment.
Endoparasites
46
Like the tobacco Mosaic virus, which infects a number of different types of plants, have a slinky-shaped capsid that twist around and encloses its genetic material
- Helical Viruses
47
Like adenoviruses,which are known to cause a range of illnesses from pink eye to pneumonia, are composed of genetic material surrounded by a many-sided capsid, usually with 20 triangular faces.
- Polyhedral Viruses
48
Like the infamous Coronavirus, are essentially helical viruses enclosed in a membrane known as an envelope, which is spiked with sugary proteins that assist in sticking to and entering host cells.
- Spherical Viruses
49
Like bacteriophages, which infect and kill bacteria, resemble a lunar lander and are composed of a polyherdal “head” and a helical body (or “soil sheath”) and legs ( or “tail fibers”) that attach to a cell membrane so that it can transfer its genetic material.
- Complex Viruses
50
are those found living outside their hosts. Many ectoparasites live on or near the organisms they require for nutrients, while some spend considerable time away from their hosts.
Ectoparasites –
51
Due to autosomal dominant mutation of PrP.
Familial/Hereditary
52
occurring at irregular intervals or only in a few places; scattered or isolated.
Sporadic
53
the study of the structure, functions and activities of bacteria
Bacteriology
54
the study of the various types of algae
Phycology
55
the study of parasites: parasitic protozoa, helminths (parasitic worms), and arthropods (certain insects and arachnids)
Parasitology
56
the study of viruses
Virology
57
-study of yeast and other fungi.
Mycology
58
Roles of microbes in soil formation and fertility; in carbon, nitrogen, phosphorus and sulfur cycles; in diseases of plants; in the digestive processes of cows and other ruminants; and in the production of crops.
Agricultural Microbiology
59
the use of microorganisms in industry
Biotechnology (Industrial Microbiology)-
60
concerned with water and sewage treatment; use bacteria like iron- and sulfur- ulitilizing bacteria to break down metals and minerals in water
Environmental Microbiology-
61
-involves the study of pathogens, the diseases they cause, and the body’s defenses against disease, is a branch of Medical Microbiology that is concerned with the laboratory diagnosis of infectious diseases of humans
Medical and Clinical Microbiology
62
Microbial Genetics involves the study of microbial DNA, chromosomes, plasmids (small, circular molecules of extrachromosomal DNA), and genes.
Microbial Genetics and Genetic Engineering
63
-contributes to our understanding of the structure and functions of microbial cells
Microbial Physiology
64
-involves the study of ancient microbes.
Paleomicrobiology
65
-includes the processing and disposal of garbage and sewage wastes, as well as the purification and processing of water supplies to ensure that no pathogens are carried to the consumer by drinking water
Sanitary Microbiology
66
-the study of the immune system and vaccines
Immunology
67
deals with the study of the occurrence, spread, and prevention of infectious diseases
Public Health and Epidemiology
68
__________________ are present in our bodies awaiting the opportunity to cause disease
► Opportunistic pathogens
69
the application of biology to solve practical problems and produce useful products economically
Biotechnology-
70
the use of living organisms to degrade environmental pollutants
Bioremediation
71
the introduction of genes from one organism to an unrelated organism and conferring new properties on that organism
Genetic Engineering
