Explanation / Answer
1.a. Antibiotic that target cell wall synthesis. So by providing Antibiotic doctor wants to supress the grorwth of the bacteria that has a thick cell wall. So the bacteria must be Gram positive. From this we can conclude the bacteria must be of Streptococcus sp . Gram positive ,short rod shaped bacteria.
b. Then Antibiotic hinders the synthesis of cell wall so the bacteria will have a weaker cell wall so it gets destroyed by osmotic stock easily.
2.Antibiotics are more selectively toxic. Because generally Antibiotic targets specific type of cells . Whereas antifungal drugs target whole fungus family and even other eukaryotic cell in smaller scale .
