Special bacterial smear test

Special bacterial smear test is a smear test method for detecting pathogens including Neisseria gonorrhoeae, Cryptococcus neoformans, Treponema pallidum, Corynebacterium diphtheriae and the like. Basic Information Specialist classification: Infectious disease inspection and classification: pathogenic microorganism inspection Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: The type and proportion of the flora in the body are normal, and the human body is in a dynamic balance. Positive: Pathogenic bacteria were detected, suggesting the presence of pathogenic bacteria. Tips: Pay attention to normal eating habits before check, pay attention to personal hygiene. Normal value The type and proportion of the flora in the body are normal, and the human body is in a dynamic balance. Clinical significance Abnormal results: (1) The main symptoms of gonococcal infection of gonorrhea include frequent urination, urgency, dysuria, purulent discharge in the urethra, cervix or vaginal opening. Or gonococcal conjunctivitis, enteritis, pharyngitis, etc., or disseminated gonorrhea symptoms. (2) C. neoformans is an important opportunity for respiratory infections. It can cause serious clinical symptoms, most commonly meningitis. (3) Diphtheria bacilli invade the body and grow only in the throat, which produces diphtheria toxin into the blood, which can cause symptoms such as myocarditis and adrenal dysfunction. (4) Symptoms of infection caused by other pathogens. People who need to check: Patients with pathogen infections such as Neisseria gonorrhoeae, Cryptococcus neoformans, Treponema pallidum, and Corynebacterium diphtheriae. Positive results may be diseases: pediatric bacterial infectious stomatitis, acute pseudomembranous candida stomatitis considerations Inappropriate crowd: No. Forbidden before examination: Pay attention to normal eating habits and pay attention to personal hygiene. Requirements for inspection: Actively cooperate with the doctor. Inspection process Drip a drop of distilled water on a clean glass slide, perform aseptic operation with an inoculating loop, pick up the culture a little, place the water droplets on the slide, mix with water to make a suspension and apply a thin layer of about 1 cm in diameter. In order to avoid excessive aggregation of the bacteria into groups, it is unfavorable to observe the individual morphology. Add one drop of water to one side of the slide, and take another ring from the coated bacterial solution to dilute it. The cloth is formed into a thin layer, and if the material is a liquid culture or a solid culture, the prepared bacterial liquid is washed, and then directly coated on a glass slide. The basic procedure is as follows: Production → Fixation → Mordant → Dyeing → Decolorization → Counterstaining → Washing → Drying → Microscopic examination. According to the morphological characteristics of various bacteria, the judgment is drawn. Not suitable for the crowd Those who do not have an indication for examination should not do this check. Adverse reactions and risks Generally no complications and harm.
