be transmitted from person to person
List four types of organisms studied in microbiology
and give characteristics of each
List some diseases caused by each type of
microorganism
Define normal flora and explain the value of normal
flora
Describe the three types of bacteria according to shape
Infectious Disease
 _______________________– tiny living things that may
cause disease in humans
 Microorganism would be considered the
_______________________and the human would be the
_______________________
 _______________________– term for microorganisms
that cause disease. Any disease causing organism is a
pathogen.
Infectious Disease
 _______________________– adverse effects on the
body as caused by the pathogen
 ________________________________________ –
relatively small, constricted to a certain area
 ______________________________________________–
whole body is affected
 ______________________________________________–
takes place when the host has been compromised
already by disease
Microbiology
 _______________________– the study of microscopic
organisms
 Includes the study of:
 B
 V
 F
 P
 A
 _______________________– Populations of
microorganisms that normally grow and live on our bodies
An Introduction to Bacteria

Bacteria
 _______________________, single-celled organisms that
grow in a wide variety of _______________________
 Genetic material not enclosed in a
_______________________
 Types of bacteria
 _______________________– can grow in the absence of
oxygen
 _______________________– require oxygen to grow
 _______________________– use oxygen if it is present but are
able to grow without oxygen if it is not available, ex. E. coli
Bacterial Characteristics
 _______________________– resistant forms of bacteria
that can tolerate long periods of dryness or other
adverse conditions
 _______________________– threadlike “tails” that aid
in movement
 _______________________– short flagella-like
structures that help bacteria glide along surfaces
 _______________________– poisons that can cause
harm to other organisms

Bacterial Diseases
 Neisseria gonorrhoeae (Cocci)
 Streptococcus pneumoniae (Cocci)
 Escherichia coli (bacilli)
 Mycobacterium tuberculosis (bacilli)
Viruses
 Extremely small infectious agent that can only
_______________________within a living cell
 Much smaller than _______________________
 Composed of _______________________core,
surrounded by a _______________________coat
 Classified by type of _______________________they
contain

Fungi
 Microscopic fungal organisms includes
_______________________and
_______________________
 The study of fungi is called _______________________
 _______________________– single-celled forms of
fungi
 _______________________– filamentous forms of
fungi

 Single-celled _______________________
 _______________________– an irregular mass of
cytoplasm that propels itself by extending part of its cell
 _______________________– covered with tiny hairs
called cilia
 _______________________– possess long, whiplike
filamentous flagella
 _______________________– obligate parasites, unable to
grow outside of hosts
