Antimicrobial Spectrum of Sulfa Drugs
Sulfonamides have broad spectrum activity against both Gram-positive and 
Gram-negative bacteria.

Type of Infections Sulfa Antimicrobic Drugs are Used Against
Sulfa drugs are used to treat some types of bacterial pneumonia, urinary tract infections, shigellosis, Nocardia infections (a type of bacterium with an unusual waxy cell wall) and specific protozoal infections.

CLASS NOTES 
from the free STEM 
education site 
Science Prof Online
Allergies to sulfonamides are common (about 3% of general population), so sulfa drugs are prescribed carefully. Hypersensitivity reactions are less frequently seen in non-antibiotic sulfonamides. The most common hypersensitivity reaction to sulfa drugs are skin reactions such as rashes and hives. However, there are several types of reactions that can be life-threatening.

Antibiotic Resistance
Bacterial resistance to sulfonamide antibiotics is also common, and sulfa drugs are frequently used in combination with trimethoprim; which blocks two steps in folic acid metabolism, and thus helps prevent the emergence of strains of bacteria resistant to sulfa drugs.
