- Fungi are spore-bearing
- Fungi may be unicellular or multicellular.
- Mycology is a term used for the study of fungi and associated diseases.
Fungal diseases are of two types:
Human infections are categorized into two types:
- Superficial infection
- Systemic infection
- Superficial infection include fungal growth from skin, nails and hairs.
- Various type of ringworm and several other fungal infections are seen on the body.
- Superficial mycosis are generally saprophytes and having capacity to digest keratin protein.
- Systemic mycosis is caused fungi which causes serious infection from general symptoms to fatal diseases.
Superficial infection is of two types:
- Surface infection
- Cutaneous infection
Some of the important fungal diseases are:
- Aspergillosis word given to large group of diseases caused by fungus infection from species Aspergillus.
- Aspergillosis is a disease occurs in humans, birds and other animals.
- The most important pathogens that are responsible for this disease are: Aspergillus fumigatus and Aspergillus flavus.
- It is chronic or acute forms.
- Coughing of blood
- Chest pain
- Infection in lungs causes cough, fever and chest pain.
- Kidney failure and liver failure.
- On chest X-ray and CT, pulmonary Aspergillosis classically manifest as a hallow sign and later, as air crescent sign.
- On microscopy, aspergillus sp. are reliably exhibit by silver stains e.g. Gridley stain or Gomori methenamine silver, gives fungal walls grey black colour.
- For aggressive invasive Aspergillosis include: Voriconazol, liposomal amphotericin B combination with surgical debridement.
- Aspergillosis is thought to affect more than 14 million people worldwide.
- This fungal infection is caused by yeast belonging to genus Candida.
- There are about twenty Species of candida which can causes infection in human. the most common is Candida albicans.
- It normally lives on skin and mucous membrane without causing any infection. However, overgrowth of the strain causes infection as mouth or throat and systemic life-threatening diseases.
- Candida infection of mouth and throat can be seen as white patches/plaques.
- On the mucosal membrane including-redness, swallow and wound near the mouth.
Diagnosis and test
- The fungal strain is scrapped from the body and seen under microscope for confirmation of the pathogen to initiate the treatment.
- Generally, they are cultured on PDA and enriched media for confirmation of foreign agent or pathogen.
Treated with antifungal medications
- Amphotericin B
- Oral candidiasis is the very much common oral infection that occurs in humans.
- About 20% of those receive chemotherapy for cancer and 20% of with AIDS.
- It is caused by various group of filamentous fungi affecting superficial skin, hair and nails.
- They are sometimes called skin lesion.
- They are generally including three strains.
