This document discusses various types of parasitic fungi and human mycoses (fungal diseases). It describes systemic mycoses that affect deep tissues, cutaneous mycoses that infect the skin/hair/nails, subcutaneous mycoses beneath the skin, and superficial mycoses of hair and skin. Specific fungal diseases are provided as examples for each category like histoplasmosis, ringworm, and athlete's foot. Opportunistic mycoses caused by generally harmless fungi that infect individuals with weakened immunity are also outlined.

As the channel name suggests, our channel will be a perfect lounge for the malayali medicos..we wil be covering videos which will be like lecture classes related to the subjects biochemistry and microbiology in which we are specialised.. It will be a better learning experience for the students especially for those who are not able to understand and follow the normal classes in college..we assure the students that you will get a basic idea regarding the topic and extra reading can be done from the reference textbooks..

Anthrax is also known as Wool sorter's disease and is zoonotic in nature. The organism responsible for this disease has been discussed here. The organism has also been used in bioterrorism attacks.

According to tissue involved, MYCOSES are classified into:
Superficial (Surface )
Cutaneous
Subcutaneous
Deep Cutaneous
Systemic (Primary )
Systemic ( Opportunistic)
Mycotic Poisoning
most of the fungal infections are opportunistic in nature.
candida albicans is the common Fungal pathogen.

shows the different fungal infections human can be exposed to. how medical treatment can be carried out to treat
use of antofungals. the different parts of the fungus
and invade the genital ridges in the sixth week of
development. here they form primitive sex cords. in
the absence of tdf, medullary cords disappear and
get replaced by a vascular stroma (ovarian medulla).
cortical cords develop and surround one or more
primitive germ cells. the germ cells subsequently
develop into oogonia, while the surrounding epithelial
cells form the follicular cells. this differentiates
undifferentiated gonads into ovaries. stroma of ovary
develops from basal mesenchyme. granulosa and theca
cells develop from celomic epithelium.
development of genital ducts
development of genital duct system and the external
genitalia occurs under the influence of hormones
circulating in the fetus. sertoli cells in the fetal testes
produce a nonsteroidal substance known as müllerian
inhibiting substance (mis) that causes regression of
müllerian ducts. androgen from the fetal testes causes
masculinization of external genitalia. in the absence of
mis, müllerian ducts develop and mesonephric duct
system regresses. in the absence of androgen, external
genitalia differentiate into female phenotype. the
müllerian duct develops between the fifth and sixth
weeks lateral to intermediate cell mass and wolffian
duct. the müllerian duct has the following three parts:
•cranial vertical portion that opens into celomic
cavity. later it differentiates into fallopian tubes.
•horizontal part crosses the mesonephric duct.
•caudal vertical part that fuses with its partner
from opposite side. this fused part later differ
entiates into uterus, cervix, and upper one-third
of the vagina.
the dorsal celomic epithelium (which forms
müllerian duct) remains open at its site of origin and
ultimately forms the fimbriated ends of the fallopian
tubes. at their point of origin, each of the müllerian
ducts forms a solid bud. each bud penetrates the
mesenchyme lateral and parallel to the wolffian duct.
as the solid buds elongate, a lumen appears in the
cranial part, beginning at each celomic opening. the first time
2. PARASITIC FUNGI AND HUMAN
Mycoses: Any fungal disease. Tend to be chronic
because fungi grow slowly.
Mycoses are classified into the following categories
(based on the level of penetration into the body
tissues):
1) Systemic or deep mycoses, often fatal.
2) Cutaneous mycoses or dermatomycoses.
3) Subcutaneous mycoses.
4) Superficial mycoses.
5) Dimorphic systemic mycoses.
4. Systemic mycoses
Fungal infections deep within the body. Can affect
a number if tissues and organs.
Usually caused by fungi that live in the soil and are
inhaled.
Examples:
Histoplasmosis (Histoplasma capsulatum): Initial
infection in lungs. Later spreads through blood to
most organs.
Coccidiomycosis (Coccidioides immites):
Resembles tuberculosis.
7. Cutaneous mycoses
Cutaneous mycoses: Fungal infections of the skin,
hair, and nails.
Secrete keratinase, an enzyme that degrades
keratin.
Infection is transmitted by direct contact or contact
with infected hair (hair salon) or cells (nail files,
shower floors).
Examples:
Ringworm (Tinea capitis and T. corporis)
Athlete’s foot (Tinea pedis)
Jock itch (Tinea cruris)
11. Subcutaneous mycoses
Subcutaneous mycoses: Fungal infections beneath
the skin.
Caused by saprophytic fungi that live in soil or on
vegetation.
Infection occurs by implantation of spores or mycelial
fragments into a skin wound.
Can spread to lymph vessels.
12. Superficial mycoses
Superficial mycoses: Infections of hair shafts
and superficial epidermal cells. Prevalent in
tropical climates.
3 Genera of dermatophytes:
Trichophyton (Hair, Skin, Nails)
Microsporum (Skin, Hair)
Epidermophyton (Skin, Nails)
17. Opportunistic mycoses
Caused by organisms that are generally harmless unless
individual has weakened defenses:
AIDS and cancer patients
Individuals treated with broad spectrum antibiotics
Very old or very young individuals (newborns).
Examples:
Aspergillosis: Inhalation of Aspergillus spores.
Yeast Infections or Candidiasis: Caused mainly by
Candida albicans. Part of normal mouth, esophagus,
and vaginal flora.
19. Dimorphic Systemic Mycoses
Caused by dimorphic fungal pathogens (by changing
their morphological form.
Geographically restricted and the primary sites of
infection is usually pulmonary, inhalation of conidia.
Histoplasmosis:
World-wide, espceially USA, sporadic cases do occur in
Australia.
Agent: Histoplasma capsulatum.
Coccidioidomycosis
Respiratory infections: Endemic in south-western USA,
nothern mexico and various centres in South America.
Agent: Coccidioides immitis.
