Streptococcal B infection
can cause urinary tract infections and throat
infections both. Since you had throat
infection followed by urine infection it could possibly be streptococcal infection. Strep throat is diagnosed by culturing the bacteria from a throat swab. In kidney disease is suspected, a urinalysis will show blood or protein in the urine, and bacteria may be cultured from either the blood or urine. Infection responds to antibiotics. Consult your doctor. Hope it helps.
