BIO 305-Microbiology 100% Verified
microbe
is a living organism that requires a microscope to be seen.
viruses
may be ten times smaller than the smallest cells
Prokaryotes (cells lacking a nucleus):
bacteria, archaea
eukaryotes (cells with a nucleus)
algae, fungi, protists
Bacterium
E. Coli on leaf stomate
Eukaryote
Stentor, a stalked protist
Archaeon
Halococcus
Virus
Herpes simplex virus
, genome
comprises the total genetic information of an organism
Fred Sanger
developed the first method of DNA sequencing that was fast enough to sequence large
genomes
Haemophilus influenzae
the first genome sequence of a cellular microbe 1995
metagenomes
collections of sequences from diverse populations of microbes taken directly from the
environment
"Rock-eating" bacteria (lithotrophs)
aided metal mining and deteriorated ancient stone monuments
Fourteenth century
bubonic plague caused by Yersinia pestis
Nineteenth century
tuberculosis caused by Mycobacterium tuberculosis
Today
acquired immunodeficiency syndrome (AIDS) caused by the human immunodeficiency
virus (HIV)
