Mycoplasma, a tiny yet troublesome bacterium, has been causing a stir in medical circles. These small organisms lack cell walls, making them unique among bacteria and challenging to combat. Their ability to slip past conventional antibiotics and cause a range of health issues has put mycoplasma on the radar of healthcare professionals worldwide.
This article aims to shed light on the transmission and risk factors associated with mycoplasma infections. It will also explore effective prevention strategies to keep these elusive bacteria at bay. Additionally, readers will gain insights into the current treatment options available for those affected by mycoplasma-related illnesses. By the end, you’ll have a better understanding of how to protect yourself and manage these infections if they occur.
Transmission and Risk Factors
How Mycoplasma spreads
Mycoplasma pneumoniae is primarily transmitted from person to person through respiratory droplets generated when an infected individual coughs or sneezes. These tiny droplets, containing the bacteria, can spread through the air and be inhaled by others in close proximity. Additionally, the bacteria may also spread via close contact with an infected person, such as sharing utensils or kissing.
Mycoplasma can survive on various surfaces, including skin and mucous membranes, facilitating its transmission. The bacteria have a relatively long incubation period, typically ranging from 1 to 4 weeks, which allows ample time for the infection to spread undetected before symptoms appear.
High-risk groups
While mycoplasma infections can affect individuals of all ages, certain groups are at a higher risk of contracting the bacteria and developing more severe symptoms. School-aged children and young adults are particularly susceptible to mycoplasma infections. This increased vulnerability is likely due to their immature immune systems and the high likelihood of close contact with infected individuals in settings such as schools and daycare centers.
People with weakened immune systems, such as those recovering from a recent illness or those with underlying health conditions, are also at an elevated risk for mycoplasma infections. These individuals may experience more severe symptoms and complications compared to healthy individuals.

Environmental factors
Environmental factors play a significant role in the spread of mycoplasma infections. Crowded and poorly ventilated spaces, such as classrooms, dormitories, and military barracks, provide ideal conditions for the bacteria to thrive and spread rapidly. The close proximity of individuals in these settings facilitates the transmission of respiratory droplets containing mycoplasma.
Additionally, mycoplasma bacteria can survive on various surfaces, including doorknobs, tables, and shared objects, for extended periods. This persistence on surfaces increases the likelihood of indirect transmission, as individuals may come into contact with contaminated objects and then touch their face, inadvertently introducing the bacteria into their respiratory system.
Prevention Strategies
Personal hygiene practices
Maintaining good personal hygiene is crucial in preventing mycoplasma contamination in cell cultures. Laboratory personnel should always wear personal protective equipment (PPE) such as clean lab coats and gloves when working in the cell culture lab. Proper handwashing techniques should be followed before and after handling cell cultures. Talking and sneezing near cell cultures should be avoided to prevent the spread of mycoplasma through aerosols and droplets. Mouth pipetting is strictly prohibited as it can introduce mycoplasma from the human oral cavity into cell cultures. Instead, mechanical pipetting devices should be used.
Furthermore, it is important to maintain a clean and tidy lab space. Work surfaces, equipment, water baths, and incubators should be regularly sterilized and cleaned. Spills should be immediately cleaned up to prevent the spread of mycoplasma. Cell culture labs should not be used for storage purposes as extra containers or equipment can block the airflow and prevent proper circulation and sterile filtration within the hood.
Safe sex practices
Mycoplasma can also be transmitted through sexual contact. Therefore, it is important to practice safe sex to prevent the spread of mycoplasma infections. This includes using condoms during sexual intercourse and avoiding sexual contact with individuals who have active mycoplasma infections. Regular testing for sexually transmitted infections, including mycoplasma, is also recommended for sexually active individuals.

Vaccination possibilities
Currently, there are no approved vaccines available for the prevention of mycoplasma infections. However, researchers are actively investigating potential vaccine candidates. Some promising targets for mycoplasma vaccines include adhesion proteins such as P1, P30, and P116, as well as the CARDS toxin. These antigens have been shown to elicit protective immune responses in animal models. DNA vaccines encoding mycoplasma antigens have also been explored as a vaccination strategy. While these vaccine candidates show promise, further research is needed to develop safe and effective vaccines for the prevention of mycoplasma infections in humans. In the meantime, adherence to good laboratory practices and personal hygiene measures remains the best approach for preventing mycoplasma contamination in cell cultures.
Treatment Options
Antibiotics for Mycoplasma
Macrolides remain the mainstay of treatment for mycoplasma infections, even with increasing resistance throughout the world. The estimated overall global prevalence of macrolide resistance is approximately 28%, with the US and Canada having rates of 10% and 12% respectively, and some regional variability. Resistance in Europe averages 5%, however rates in Italy are approximately 20%. The highest resistance prevalence is in Asia with rates of more than 50% in Japan and 80% in China. If symptoms do not resolve with macrolide treatment, tetracyclines (minocycline) or fluoroquinolones can be prescribed.
Challenges in treatment
Treatment of mycoplasma infections can be challenging due to the unique characteristics of the organism. Mycoplasma lacks a cell wall, making it resistant to many common antibiotics such as beta-lactams, glycopeptides. The biological features of mycoplasma also result in the ineffectiveness of a number of other substances including sulfonamides, rifampin, polymyxin, nalidixic acid. The rapid development of resistance to antimicrobial agents in mycoplasmas, whose mechanisms are not entirely clear, represents a significant problem. Long-term clinical trials in various regions of the world are required to assess the prospects of new antibiotics such as deformylase inhibitors, which have shown activity against urogenital mycoplasmosis.

Alternative therapies
Antimicrobial peptides such as melittin, globomycin, gramicidin C, surfactin, valinomycin, alamethicin, cecropins, and magainin 2 are not widely used to control mycoplasma at the moment. Studies have found that mycoplasma can successfully develop resistance to these drugs as well. More research is needed on the mechanisms of mycoplasma resistance to antimicrobial peptides. In addition to pharmacological treatments, other therapeutic modalities are being explored. Magnetic therapy, acupoint application, cupping, acupuncture, massage, and traditional Chinese medicine have demonstrated effects in reducing airway sensitivity, improving circulation, enhancing clinical efficacy, relieving symptoms, improving quality of life, and reducing adverse reactions. These complementary and alternative therapies play an important role in the adjuvant treatment of severe mycoplasma pneumonia. However, further high-quality, large sample, and multicenter studies are needed to fully evaluate their efficacy and safety in the management of mycoplasma infections.
