Definition A throat culture requires swabbing the throat, streaking a culture plate, and allowing the organisms to grow for isolation and identification of pathogens. The test uses a strip or disc that is chemically coated with an antibody specific for the strep antigen. Other possible pathogens suspected in a case of acute pharyngitis (eg, C diphtheriae) may also be identified with throat culture. Medical Microbiology. The bacterium that most often causes a sore throat is Streptococcus pyrogenes or Group A beta-hemolytic streptococcus. Antiseptic mouthwash should be avoided before this test. So I was looking at my test results and it seems that the times I feel the worst are when my normal upper respiratory flora levels are reported to be "heavy growth" (HEAVY GROWTH NORMAL UPPER RESPIRATORY FLORA ISOLATED). The soreness can begin suddenly and cause severe pain when you swallow. Losing your voice can be frustrating. my sputum culture test results-significant inflammation present.
