Communicable diseases
caused by microorganisms that are not transferred from one person to another
Non communicable diseases

bacteria
exchanged among bacteria and very often contain the genes that make bacteria resistant to antibiotics
Plasmids
spherical bacteria that usually grow in clusters or chains
Cocci
rod shaped bacteria
Bacilli
spiral shaped bacteria
spirilla
one cell splits into two cells, each one being a new bacterium
binary fission
identical to other bacteria in structure but reproduce only inside other living cells
Rickettsiae
extremely resistant to harsh environmental conditions and allow bacteria to survive extremely long periods of unfavorable conditions
Endospores
lives where air is present and obtain oxygen from the air
aerobic bacteria
live in the absence of oxygen
anaerobic bacteria
every infectious disease is caused by a specific germ
germ concept of disease
French chemist and microbiologist, applied scientific theory to the practical problems of industry and medicine
Louis Pasteur
molecule of genetic material enclosed in a geometric protein structure called a capsid
virus
(single celled animals) are responsible for several well known diseases common in tropical region
Protozoa
carried by water droplets, such as those discharged by a sneeze or a cough
Droplet infectio
displays no symptoms of disease
but harbors the pathogens in his body
and can pass them to infect others
Carrier
An animal that transmits infection
Vector
