Syed Hussain Shah's presentation topic is on mycosis, or fungal infections. Mycosis is caused by fungi like Aspergillus, Histoplasma, and other pathogenic fungi. Those at risk include people with weakened immune systems from HIV/AIDS, steroid use, chemotherapy, or diabetes. Mycoses are classified by the tissue initially infected, such as superficial infections of the outer skin/hair, cutaneous infections deeper in the skin/nails, subcutaneous infections of the dermis and muscles, and systemic infections originating in the lungs or from opportunistic pathogens in immunocompromised individuals. Prevention methods include keeping skin clean and dry, maintaining good hygiene, and washing clothes after contact

2. Mycosis
A disease cause by mycosa or mycotic organism
e.g
Fungi like aspergillus, histoplasma or other
pathogenic fungi such type of infection is called
“mycosis”.

3. Causes :
Weakened immune system e. g
HIV/AIDS
Under steroid treatment
People taking chemotherapy
People with diabetes also susceptible
to fungal disease.

4. Classification of Mycosis:
Mycoses are classified according to the tissue
levels initially colonized.
Superficial mycoses
 Superficial mycoses are limited to the
outermost layers of the skin and hair.
An example of such a fungal infection is
Tinea versicolor
 effect specially chest,back,and upper arms
and legs.

5. Cutaneous Mycosis:
Cutaneous mycoses extend deeper
into the epidermis, and also include
invasive hair and nail diseases.
The organisms that cause these
diseases are called dermatophytes.

6. Subcutaneous Mycoses
Subcutaneous mycoses involve the
dermis, subcutaneous tissues and
muscle.
 These infections are chronic and can
be initiated by piercing trauma to the
skin which allows the fungi to enter.
 These infections are difficult to treat
and may require surgical interventions

7. Systemic mycoses due to
primary pathogens
Systemic mycoses due to primary
pathogens originate primarily in the
lungs and may spread to many organ
systems
 In general primary pathogens that
cause systemic mycoses are
dimorphic

8. Systemic mycoses due to
opportunistic pathogens:
Systemic mycoses due to
opportunistic pathogens are infections
of patients with immune deficiencies
e.g AIDS
. Examples of opportunistic mycoses
include Candidiasis and Aspergillosis.

9. Prevention:
Keeping the skin clean and dry.
 maintaining good hygiene,
Because fungal infections are
contagious, it is important to wash
after touching other people or animals.
Sports clothing should also be washed
after use.
