Question

The pathogen Microsporum, responsible for ringworm disease in humans belongs to the same Kingdom of organisms as that of
A. Taenia, a tapeworm
B. Wuchereria, a filarial worm
C. Rhizopus, a mould
D. Ascaris, a roundworm

Answer 1

Many fungi belonging to genera Microsporum, Trichophyton and Epidermophyton are responsible for ringworms, one of the most common infectious diseases in man. Mode of transmission: Ringworms are generally transmitted from soil or by using infected towels, clothes or even the comb of infected individuals.

Complete answer:
Microsporum belongs to kingdom fungi and class ascomycetes . The symptoms of fungal disease Appearance of dry, scaly lesions on various parts of the body such as skin, nails and scalp are the main symptoms of the disease. These lesions are accompanied by intense itching. Heat and moisture help these fungi to grow, which makes them thrive in skin folds such as those in the groins or between the toes (athletes foot). In Tinea cruris, the groin and perineum are involved. In Tinea barbae, the beard areas of the face and neck are involved. Tinea pedis or athlete's foot affects feet.
Now let us know from given options which organism belongs to fungi:-
Taenia, a tapeworm :- it belongs to kingdom Animalia and phylum Platyhelminthes commonly known as flatworms. They cause a disease commonly known as taeniasis. This disease occurs when humans eat uncooked beef.
Wuchereria, a filarial worm :- it belongs to kingdom Animalia and phylum Aschelminthes They cause disease Filariasis. Mode of transmission: The pathogens are transmitted to a healthy person through the bite of infected female Culex (mosquito).
Rhizopus, a mould :- this belongs to kingdom fungi and class zygomycetes. It is commonly known as bread mould. They cause disease Rhinocerebral mucormycosis. As microsporum also belongs to kingdom fungi so this option is correct.
Ascaris, a roundworm :- it belongs to kingdom Animalia and phylum Aschelminthes they cause disease Ascariasis Mode of transmission: A healthy person acquires this infection through contaminated water,

Our required answer is C that is Rhizopus, a mould.

Note: Maintenance of personal and public hygiene is very important for prevention and control of many infectious diseases. Personal hygiene includes keeping the body clean, consumption of clean drinking water, food, vegetables and fruits etc.
Public hygiene includes proper disposal of waste and excreta, periodic cleaning and disinfection of water reservoirs, pools and tanks. These measures are particularly essential where the infectious agents are transmitted through food and water such as typhoid, amoebiasis and ascariasis.
