Some microbes form substances called hemolysins that have the specific action of destroying red blood cells; the beta-hemolytic streptococcus is an example. Intravenous administration of a hypotonic solution or plain distilled water will also destroy red blood cells by causing them to fill with fluid until their membranes rupture. In a transfusion reaction or in erythroblastosis fetalis , incompatibility causes the red blood cells to clump together. The agglutinated cells become trapped in the smaller vessels and eventually disintegrate, releasing hemoglobin into the plasma. Kidney damage may result as the hemoglobin crystallizes and obstructs the renal tubules, producing renal shutdown and uremia. Snake venoms and vegetable poisons such as mushrooms may also cause hemolysis.

Streptomycin , antibiotic synthesized by the soil organism Streptomyces griseus. The drug acts by interfering with the ability of a microorganism to synthesize certain vital proteins. It was the first antimicrobial agent developed after penicillin and the first antibiotic effective in treating tuberculosis.
Diagnosis , the process of determining the nature of a disease or disorder and distinguishing it from other possible conditions. The term comes from the Greek gnosis , meaning knowledge. Symptoms that appear early in the course of a disease are often more vague and undifferentiated than those that arise as the disease progresses, making this the most difficult time to make an accurate diagnosis.
