Both mycoplasma and chlamydia have cell membranes, but neither has a cell wall.

Chlamydia is a group of extremely small, non-motile microorganisms that grow exclusively within cells. Chlamydia can be divided into 4 types, namely Chlamydia pneumoniae, Chlamydia psittaci, Chlamydia trachomatis and Chlamydia bovis.

Chlamydia is a Gram-negative pathogen, a type of prokaryotic microorganism that can pass through bacterial filters, parasitize within cells, and has a unique development cycle. Chlamydia is an organism smaller than bacteria but larger than viruses. It is an obligate intracellular parasitic pathogen that is similar to bacteria and viruses and has a two-phase life cycle.

It does not have the ability to synthesize high-energy compounds ATP and GTP, which must be provided by the host cell, so it becomes an energy parasite. It is mostly spherical or pile-shaped, has a cell wall and a cell membrane, is a prokaryotic cell, and generally parasitizes in within animal cells. Currently there are four types of chlamydia: trachoma, pneumonia, parrot and livestock.

Mycoplasma (mycoplasma) is a type of smallest prokaryotic microorganism that has no cell wall, is highly pleomorphic, can pass through a bacterial filter, and can be cultured and proliferated in artificial media. Because it can form filamentous and branched shapes, it is called mycoplasma. Mycoplasmas are widely found in humans and animals.

Most of them are not pathogenic. Mycoplasmas that are pathogenic to humans mainly include Mycoplasma pneumoniae, Ureaplasma urealyticum, Mycoplasma hominis, Mycoplasma genitalium, etc. Macrophages, IgG and IgM all have certain killing effects on mycoplasma.

Extended information:

Most mycoplasmas reproduce slower than bacteria. The optimal growth temperature is 35°C and the optimal pH value is 7.8 to 8.0. When cultured on solid media, typical "poached egg"-shaped colonies are formed.

Mycoplasma has weak resistance, is sensitive to heat and drying, is sensitive to 75% ethanol, creol soap solution, and is sensitive to erythromycin, tetracycline, spiramycin, streptomycin, kanamycin, etc. Sensitive to drugs, but not sensitive to penicillin antibiotics.

Chlamydia pneumoniae is considered a common cause of pneumonia, bronchitis and other respiratory infections; Chlamydia bovis is found only in cattle and sheep; Chlamydia psittaci causes psittacosis and is caused by humans inhaling the excretion of infected birds Infection caused by dry dust particles of objects often causes high fever, headache, myalgia, chills and upper and lower respiratory tract discomfort.

Some patients may be complicated by encephalitis, myocarditis or thrombophlebitis. In addition to causing trachoma, Chlamydia trachomatis is also a recognized source of infection for sexually transmitted diseases.

Almost half of nongonococcal urethritis is caused by Chlamydia trachomatis infection. It can also cause urethral syndrome and lymphogranuloma venereum, male urethritis, epididymitis, female infertility, cervicitis, pelvic inflammatory disease, etc. Infection of newborns through the birth canal can cause ophthalmia neonatorum or neonatal pneumonia.

Chlamydia trachomatis can also cause pneumonia in adults and is also more harmful to pregnant women. It can cause ectopic pregnancy, miscarriage, stillbirth, chorioamnionitis, premature birth, etc.
