Solution
Q1 Answer : Schistomiasis is a tropical disease caused by parasitic infection with worms

2. (Parasitic flat worms ) it is aslo called as snail fever and Bilharzia.
.Q2. Signs and symptoms may include abdominal pain, diarrhea, bloody stool, or blood in the
urine. Those who have been infected a long time may experience liver damage, kidney failure,
infertility, or bladder cancer.
Diagnosis of infection is confirmed by the identification of eggs in stools. Eggs of S. mansoni are
approximately 140 by 60 µm in size, and have a lateral spine. The diagnosis is improved by the
use of theKato-Katz technique (a semi-quantitative stool examination technique). Other methods
that can be used are enzyme-linked immunosorbent assay (ELISA), circumoval precipitation test,
and alkaline phosphatase immunoassay.
S.haematobium is the infectious agent which is also called as worlds deadliest schistosome
The disease is found in tropical countries in Africa, the Caribbean, eastern South America,
Southeast Asia, and the Middle East. S. mansoni is found in parts of South America and the
Caribbean, Africa, and the Middle East; S. haematobium in Africa and the Middle East; and S.
japonicum in the Far East. S. mekongi and S. intercalatum are found locally in Southeast Asia
and central West Africa, respectively
The classification of S.interclatum is as follows
Schistosoma intercalatum
Classification of vector
Anopheles
Some important species are:
Classification of malarial parasite P. vivax
In the case of human malarias, the definitive host is often referred to as the vector. The family
contains about twelve genera, of which one is Plasmodium, which itself is now often divided up
into numerous sub-genera, and then again into hundreds of different species, of which five infect
humans (P. falciparum, P. vivax, P. ovale, P. malariae and P. knowlesi).
Answer :
Cryptococcus neofmans is a fungi
Both A&D are correct
Q3. More than 6 months

3. The duration of treatment depends on whether it is a superficial fungal infection or deep tissue
fungal infection. Superficial fungal infection can take few days to few months to heal. Deep
tissue fungal infection can take upto few years to treat
Q4. answer: Cryptococcus gattii is an another speicies which can cause the disease in humans
Q5. Answer : By inhalation of fungus which results in lung infection that may spread to the brain
causing Meningo encephalitis
The symptoms are fever, Malaise, pleurotic chest pain, cough, hemoptysis, headache, Nausea
and vomitting , meningitis , seizurs, coma and some people may develop skin changes
Q6 answer : Cryptococcus speices is found in bird feces through out the world but usually the
bird themselves are infected are sick humans and animals usually get infections from inhaling
dust contaminated with bird feces but humans donot transmit to another human or animals.
However C. gatti is accquired by inhalation of air borne plant material.
The people infected with C.neoforman usually have some defect in cell mediated immunity
(HIv/AIDS ) however C gatti usually infecets immuno competent individuals (most occur in
normal indivisuals)but can infect immuno compromised people.
