Chicken Production Manual,

Microorganisms constitute a large group of living
cells that complete their life cycle in their minute
state; they do not form conglomerates of cells as
are found in the higher forms of life.
Most such cells remain in a single form, although
they may align themselves with other similar cells
to form long filaments or chains. Being living or-
ganisms, their function is similar to that of higher
organisms; they digest and assimilate food, and ex-
crete waste products.
As do higher forms of life, they necessarily must
fight for survival. Being small, they have been pro-
vided by nature with a survival potential through
their ability to reproduce in extremely large num-
bers. These large numbers mean that dissemination
is great; most microorganisms are abundant eve-
rywhere.
Some microorganisms are necessary to complete
various reactions required to sustain the complex
forms of life. Others are pathogenic; they produce
certain reactions that are detrimental to the higher
forms, among which is the chicken.
The organisms producing diseases in chickens are
too small to be seen with the naked eye; a micro-
scope must be used. All such organisms are not
similar in structure, size, chemical composition,
mode of nutrition, or in the manner in which they
attack their host. In the main such organisms may
be divided into four classes: (1) bacteria, (2) vi-
ruses, (3) protozoa, and (4) fungi. Although the
organisms within each of these groups are similar
in many respects, most may be identified only by
using intricate laboratory techniques.
