How is mycoplasma treated in cell culture?

There are three classes of antibiotics that kill mycoplasma when used at relatively low concentrations: tetracyclines, macrolides and quinolones. Tetracyclines and macrolides block protein synthesis by interfering with ribosome translation, whereas quinolones inhibit replication of mycoplasma DNA.

Where does mycoplasma come from cell culture?

There are three major sources leading to mycoplasma contamination of cell cultures in the laboratory: infected cells sent from another lab; contaminated cell culture medium reagents such as serum and trypsin; and laboratory personnel infected with M. orale or M. fermentans.

How is mycoplasma cultured?

Culturing on agar plates/broth is considered the ‘gold standard’ for detecting mycoplasmas. In this method, the supernatant from the cell culture is added to the liquid or semi-solid medium (containing nutrients essential for mycoplasma growth).

How do you test mycoplasma in cell culture?

The only way to confirm mycoplasma contamination is by routine testing using one or more special techniques, including direct growth on broth/agar, specific DNA staining, PCR, ELISA, RNA labeling and enzymatic procedures.

What are the symptoms of mycoplasma?

What are the symptoms of mycoplasma infection? Typical symptoms include fever, cough, bronchitis, sore throat, headache and tiredness. A common result of mycoplasma infection is pneumonia (sometimes called “walking pneumonia” because it is usually mild and rarely requires hospitalization).

Can you filter out mycoplasma?

Mycoplasma can be reduced by filtration with 0.1 μm filters.

What is the best method to detect mycoplasma?

Mycoplasma contamination can be detected by polymerase chain reaction (PCR). PCR is easy, sensitive, specific, fast, reliable, efficient and costeffective. The PCR test is based on the detection of 16S rRNA molecules of the most common species of mycoplasma contaminating cell cultures.

Why is mycoplasma bad?

How bad does it get? Mycoplasma contamination affects the host cells’ metabolism and morphology, causes chromosomal damage and aberrations, and causes cytopathic responses. Therefore, data generated from contaminated cells can be unreliable. And contamination is pervasive.

Does mycoplasma affect cell growth?

Mycoplasma compromises cell culture-based experiments in the following ways: Competes for nutrients – hinders cell growth and proliferation. Exposes cells to unwanted metabolites. Alters levels of protein, RNA, or DNA synthesis.

Does mycoplasma ever go away?

Infections related to Mycoplasma go away on their own without any medical intervention, that is when the symptoms are milder. In case of severe symptoms, a Mycoplasma infection is treated with the help of antibiotics like azithromycin, clarithromycin, or erythromycin.

What is the best antibiotic for mycoplasma?

What is the treatment for mycoplasma infection? Antibiotics such as erythromycin, clarithromycin or azithromycin are effective treatment.

How do I get rid of mycoplasma infection?

What is the treatment for mycoplasma infection? Antibiotics such as erythromycin, clarithromycin or azithromycin are effective treatment. However, because mycoplasma infection usually resolves on its own, antibiotic treatment of mild symptoms is not always necessary.

How is Mycoplasma treated in a cell culture?

A high percentage of cell lines are chronically infected with various mycoplasma species. The addition of antibiotics that are particularly effective against these contaminants to the culture medium during a limited period of time is a simple, inexpensive, and very practical approach for decontaminating cell cultures.

How are mycoplasmas resistant to many common antibiotics?

Moreover, given their lack of a cell wall, they are resistant to many common antibiotics such as penicillin and streptomycin. Hundreds of mycoplasmas can attach to a single eukaryotic cell, eventually invading the host by fusing with the cell membrane.

How is InvivoGen used in the treatment of Mycoplasma?

InvivoGen also provides products to treat contaminated cell cultures, including Plasmocin™, a well-established anti-Mycoplasma reagent; and Normocin™, which is used as a “routine addition” to cell culture media to prevent mycoplasma, bacterial and fungal contaminations.

What are the side effects of Mycoplasma contamination?

The side-effects of mycoplasma contamination on cell cultures are 1. inhibition of proliferation, 2. increment in cell death, 3. fragmentation of DNA and 4) morphological features of apoptosis (72) (Table 3). DNA fragmentation and loss of chromosomal DNA in monocyte cell lines are caused by M. fermentans.
