4. Zoonotic disease
Disease that can be transferred from animal to
human is called zoonotic disease.
Human
Animal

5. Fungal Zoonotic Diseases:
-Dermatophytosis
-Blastomycosis
-Aspergillosis
-Histoplasmosis
-Coccidiodomycosis
-Pityriasis
-Pneumocystosis
-penicilliosis
-Cryptococcosis
-Adiaspiromycosis
-Entomophthoromycosis

6. Zoonotic and public health importance
Disease: Dermatophytosis
Causal agent:
- Microsporum spp
-Tricophyton spp
Transmission:
Direct contact
Target animals:
Domesticated mammals
Clinical signs of disease in animal:
Ring lesion with central healing and
crusts at the peripheral area.
Clinical signs of disease in human:
Tinea capitis,Tinea manum, Tinea
barbae, Tinea corporis, Tinea ungium,
Tinea pedis

7. Blastomycosis
Causal agent:
- Blastomyces dermatidis
Transmission:
Inhalation of airborne conidia
Target animals:
Dogs, cats, horses, marine mammals.
Clinical signs of disease in animal:
Cutaneous, pulmonary, systemic infection
Clinical signs of disease in human:
Cutaneous, pulmonary infection
(granulomatous and suppurative lesions in
lung, skin and bones)

8. Aspergillosis
Causal agent:
- Aspergillus spp
Transmission:
Enironmental exposure to decaying vegetable
& grains
Target animal:
Birds & mammals
Clinical signs of disease in animal:
Allergic & respiratory problems
Clinical signs of disease in human:
Allergic sinusitis; pneumonia , (can be fatal);
infections of other organs, tissues

9. Histoplasmosis
Causal agent:
- Histoplasma capsulatum
Transmission:
Inhalation of the fungus
Target animals:
Cattle, sheep, horses
Clinical signs of disease in animal:
Chronic gastrointestinal infection and
disseminated infection
Clinical signs of disease in human:
Chronic progressive lung disease, chronic
cutaneous or systemic disease

10. Coccidiodomycosis
Causal agent:
-Coccidioides immitis
Transmission:
Inhalation of arthroconidia and skin
trauma
Target animals:
Primates,dogs, cats, horses, domesticated or
wild mammals, snakes.
Clinical signs of disease in animal:
Asymptomatic to severe and fatal infection.
Clinical signs of disease in human:
Cutaneous, pulmonary, disseminated
infection

11. Pityriasis
Causal agent:
-Malassezia spp
Transmission:
Malassezia yeasts are commensal of human
skin.
Target animals:
Dogs, cats, cows, sheep, pig, horse.
Clinical signs of disease in animal:
Dermatitis, alopecia, stenosis, otitis externa.
Clinical signs of disease in human:
Chronic superficial disease of the skin
(pityriasis vesicolor), folliculitis,
dandruff,fungaemia

animals

cats
Clinical signs of disease in animal:

contagiosum-like lesions of the skin and
mucosa .

14. Cryptococcosis
