1

Bacillus (Bacilli - plural)

rod-shaped bacteria.

2

Bacteria

a prokaryotic one-celled microorganism of the Kingdom Monera, existing as free-living organisms or as parasites, multiplying by binary fission and having a large range of biochemical properties.

3

Bacteriology

the science that studies bacteria.

4

Binary fission

a method of asexual reproduction involving halving of the nucleus and cytoplasm of the cell followed by the development of each half into a new individual cell.

5

Capsule

a coating that surrounds some bacterial cells; a loose gel-like structure that, in pathogenic bacteria, helps to protect against phagocytosis.

6

Chlamydia

a large group of non-motile, gram-negative intracellular parasites.

7

Coccus (Cocci - plural)

the type of bacteria that is spherical or round in form.

8

Diplobacilli

a pair of bacilli linked end to end.

9

Diplococci

spherical bacteria that occur in pairs.

10

Endospore

a thick-walled body produced by a bacterium to enable it to survive unfavorable environmental conditions.

11

Fungi (fungus)

a group of diverse and widespread unicellular and multicellular organisms, lacking chlorophyll, usually bearing spores and often filamentous.

12

Microbiology

scientific study of microorganisms and their effects on other living organisms.

13

Mycology

the branch of science concerned with the study of fungi.

14

Mycoplasmas

a group of bacteria that lack cell walls and are highly pleomorphic (able to assume different forms.)

15

Prion

a small proteinaceous infectious particle that believed to be responsible for spongiform encephalopathies in humans and other mammals.

16

Protozoa

eukaryotic, animal-like, unicellular organisms; some of which may be pathogenic.

17

Protozoology

science that deals with the study of protozoa.

18

Rickettsia

a genus of gram-negative, pathogenic, obligate intracellular parasitic bacteria.

19

Rickettsiology

area of science that studies Rickettsia.

20

Spirillum (Spirilla - plural)

a genus of spiral bacteria having a corkscrew shape with a rigid cell wall.

21

Spirochete

spiral-shaped bacteria having a flexible cell wall.

22

Staphylococci

a genus of gram-positive, non-motile, opportunistic bacteria which tend to aggregate in irregular, grape-like clusters.

23

Streptobacilli

rod-shaped bacteria occurring in chains.

24

Streptococci

spherical-shaped bacteria occurring in chains.

25

Vibrio

a genus of spiral bacteria which are curved or bent rods that resemble commas.

26

Virology

the study of viruses and viral diseases.

27

Virus

an intracellular, infectious parasite capable of replicating only in living cells, containing only one form of nucleic acid (DNA or RNA).
