What is Pathology?

Microbiology

Is the study of micro-organisms

Pathology

Is the study of disease (pathogenic or non-pathogenic)

* Bacteria - spores

* Viruses

* Fungi

*Microscopic single cell organisms

*Survive as spores when conditions are not favourable for them to grow and reproduce.

*Rigid outer wall that determines their shape.

Rod shaped with pointed ends or round ends

Round ended

Pointed ended

Circular bacteria's

Circular bacteria.

Colonies living in clusters.

Circular bacteria's.

Colonies living in chains.

Spiral shaped

RESEARCH THE FOLLOWING AND DETERMINE THE BACTERIAL CAUSE OF:

*CARIES

*PERIODONTAL DISEASE

*ANUG

*GUM BOILS

*LEGIONAIRES

*Streptococcus Mutans

*Lactobacillus

*Actinomyces

*Porphyromonas gingivalis

*Prevotella intermedia

*Treponema denticola

Staphylococci

Acute necrotising ulcerative gingivitis

*Bacillus fusiformis

*Borrelia Vincenti

*legionella

*Smaller than Bacteria

*Live within the cells of other organisms, such as humans.

*Reproduce within the cells of their host.

Vaccinations have been developed to prevent many viral diseases.

Harmful dose of the dead virus is injected into the individual

Causes the body's immune system to fight against it by making ANTIBODIES

Antibodies fight the viral attack and prevent the individual becoming ill

*Hepatitis A,B,C – Inflammatory liver diseases. Nurses need Hepatitis B vaccinations.

*Herpes Varicella- Chickenpox.

*Human Immunodeficiency Virus(HIV)-Acquired immune deficiency syndrome(AIDS).

*Herpes Zoster- Shingles

*Herpes simplex type 1 – Cold sores

*Epstein- Barr- Glandular fever.

*Paramyxovirus- Mumps

*Creutzfeldt-Jakob-Disease (CJD)

*Plant like organisms.

*Live on the outer surface of the body.

*Candida Albicans.

*Oral Thrush- white film, sore patches on soft tissues of oral cavity, associated with ill general health, medication or AIDS

*Denture stomatitis- denture sore mouth

*Research has uncovered the existence of prions

*These are not micro-organisms but a special protein that are capable of causing disease

*These diseases include the human form of Creutzfeldt-Jakob disease (vCJD) this protein may be found in the nerve tissue of pulp
