16) SUPERFICIAL MYCOSIS IS A MYCOTIC INFECTION THAT CAN ATTACK KERATINIZED
AREAS OF THE BODY (STRUCTURES LIFE HAIR, NAILS, ETC.)
17) HISTOPLASMOSIS, A DIMORPHIC FUNGI, IS KNOWN FOR ITS ABILITY TO PRODUCE
TUBERCLE LIKE GRANULOMAS IN LUNGS AS WELL AS IN SEVERAL OTHER ORGANS
OF THE BODY.
18) AMPHOTERICIN ‘B’ AS AN ANTIMYCOTIC DRUG IS OBTAINED FROM A SOIL
BACTERIUM STREPTOMYCES, A GRAM POSITIVE BACTERIUM IN THE SOIL.

SEATED MYCOSES. THIS DRUG WAS OBTAINED FROM ANOTHER FUNGI NAMED
PENICILLIUM GRISOFULVUM
20) CANDIDIASIS, AS A MYCOSIS, CAN INVOLVE SUPERFICIAL, DEEP SEATED AS WELL AS
INTERMEDIATE AREAS OF THE BODY, BUT IN GENERAL, IT (CANDIDA) IS CLASSIFIED
AS AN INTERMEDIATE MYCOSIS CAUSING AGENT.
21) FUNGI IN COMPARISON TO BACTERIA, IS MULTICELLULAR, EUKARYOTIC, STEROL
CONTAINING ORGANISM.
22) POLIO VIRUS AS AN RNA VIRUS, REPRODUCES BY FIRST PRODUCING AN APPROPRIATE
DNA AND THEN SYNTHESIS FOLLOWED BY ASSEMBLY.
