Microorganisms Escaping The "Filter" Intercept

2025-11-16


In the medical industry, bacterial filters are commonly used at the outlet or inlet of equipment such as ventilators, oxygen supplies, infusion pumps, and plasma exchange machines to prevent bacteria, viruses, and other microorganisms from entering the human body. There is a type of microorganism that is neither bacteria nor viruses; No cell wall, able to pass through bacterial filters; It is the smallest microorganism that can reproduce in non living cultures. This type of microorganism is mycoplasma. The main pathogenic mycoplasma to humans includes Mycoplasma pneumoniae, Mycoplasma hominis, Mycoplasma genitalium, Mycoplasma penetrans, and Ureaplasma urealyticum.

Mycoplasma pneumoniae - causing primary atypical pneumonia in humans

Pneumonia caused by Mycoplasma pneumoniae is more common in children aged 5 and above, but can also occur in children under 5 years old. The main clinical manifestations are fever and cough, with severe cough accompanied by headache, runny nose, sore throat, ear pain, etc. Fever is mainly characterized by moderate to high fever, and persistent high fever indicates severe illness. Some children have wheezing symptoms, which are more common in infants and young children. If the child experiences persistent high fever, severe cough, difficulty breathing, poor mental state, etc., medical attention should be sought as soon as possible. Mycoplasma pneumoniae is neither a common bacterium nor a virus, but a type of microorganism without a cell wall. Common antibiotics such as penicillin or cephalosporin are ineffective and cannot be treated as a common cold or flu. Once a child has symptoms such as fever and cough, they must go to a regular medical institution for treatment. Do not purchase antibiotics without authorization, otherwise it will only delay the condition. The treatment of Mycoplasma pneumoniae pneumonia in children mainly involves macrolide drugs such as azithromycin.

Ureaplasma urealyticum and Mycoplasma hominis - cause non gonococcal urethritis in humans. About 20% -30% of patients with non gonococcal urethritis are caused by these two types of mycoplasma, which are the second most common pathogens of non gonococcal urethritis and cervicitis. The infection rates of Ureaplasma urealyticum and Mycoplasma hominis in the urogenital tract of adults are mainly related to sexual activity, that is to say, the number of sexual intercourse times and the number of sexual partners, regardless of gender. According to statistics, the infection rate of mycoplasma in women is higher, indicating that the female reproductive tract is more susceptible to mycoplasma growth than the male reproductive tract. In addition, the infection rate of Ureaplasma urealyticum is higher than that of Mycoplasma hominis. Macrolides and doxycycline can be used as preferred antibiotics for the treatment of mycoplasma infections, and doxycycline is usually the preferred drug for the treatment of mycoplasma infections.
