Mycoplasma infection blood routine manifestations

Mycoplasma infection is a relatively common infection phenomenon. For example, some sexually transmitted diseases may be caused by mycoplasma infection. The peripheral white blood cell count in a routine blood test is generally normal. At this time, there may be an increase in acidic granulocytes. These are some manifestations of mycoplasma infection in the routine blood test. If mycoplasma infection occurs, other examination methods are needed. The most direct one is smear microscopy and taking pharyngeal secretions.

2. Diagnostic criteria for mycoplasma infection

The diagnosis is made based on laboratory test results. Culture and biochemical reactions: Mycoplasma is facultative anaerobic and grows better under the conditions of 5%-10% CO2 and 80%-90% humidity. The main components of mycoplasma cells, cholesterol and protein, come from the culture medium, which needs to contain serum, egg yolk, etc. The colonies are shaped like fried eggs, and are generally large, 100 to 300 nm, and take 7 to 14 days to grow. Another type has colonies of 10 to 25 nm, grows fast, and only takes 24 to 48 hours. It is called the T strain, which is Mycoplasma urealyticum.

3. Methods for detecting mycoplasma infection

Direct smear microscopy: take pharyngeal secretions, sputum, respiratory membranes or other parts of the specimen for smear, and perform GZmesa staining. The protozoa are stained red and the protozoa are stained dark blue. Chlamydia trachomatis inclusion bodies contain glycogen. 801 dyed brown. Rapid antigen detection usually uses monoclonal antibody direct immunofluorescence method to detect Chlamydia in specimens. The 2I-IsA method can also be used to add anti-Chlamydia antibodies, enzyme-labeled antibody 18G and substrate for colorimetric quantitative detection. These two methods are simple and sensitive. Chest X-rays of Chlamydia pneumonia are nonspecific, mostly showing unilateral lower lobe infiltration, manifesting as segmental pneumonia, and in severe cases, extensive bilateral pneumonia. The pathogenic mechanism of mycoplasma and chlamydia is to inhibit the metabolism of infected cells, dissolve and destroy cells, and lead to the release of lytic enzymes and the cytotoxic effect of metabolites, causing allergic reactions and autoimmunity.

Causes of mycoplasma infection 1. The causes of mycoplasma infection are related to the characteristics of mycoplasma. Mycoplasma is a type of prokaryotic cell microorganism with a size between bacteria and viruses. There are three types of mycoplasma that are pathogenic to humans. Among them, ureaplasma urealyticum is a common pathogen of the human urogenital tract, causing serious harm of mycoplasma infection. It is related to many urogenital tract infections, perinatal infections and infertility, and is one of the pathogens of sexually transmitted diseases. Mycoplasma blood test results

2. Human characteristics are also the cause of mycoplasma infection. After mycoplasma infects the human body, it first invades columnar epithelial cells and grows and multiplies inside the cells, and then enters the cells of the mononuclear macrophage system and proliferates. Because mycoplasma multiply inside cells, causing the death of infected cells, they can also evade the host's immune defense function and obtain intermittent protection. Adults are mainly infected through sexual contact, while newborns are infected through their mother's reproductive tract during delivery. The infection site in adult males is the urethral mucosa, and in females it is the cervix. In neonates, it mainly causes conjunctivitis and pneumonia.
