  • Attempts were made to evaluate the efficacy of three fluorochromes, i.e., DAPI (4'-6-diamidino-2-phenylin-dole-2HCl), aniline blue and quinacrine(quinacrine mustard dihydrochloride) for the detection of mycoplasma infections in jujube (Zizyphus jujuba), mulberry (Mows alba) trees and periwinckle (Catharanthus roseus) plant by fluorescence microscopy. Stem sections from these plants infected with mycoplasma-like organisms (MLO) produced distinct fluorescence in the phloem when stained with DAPI, aniline blue or quinacrine, while fluorescence was absent in the healthy plants. The use of these fluorochromes provided simple and efficient techniques for the diagnosis of MLO infections. IOf the three fluorochromes tested, DAPI was found to be most efficient.

  • Mycoplasma pneumoniae is the most common pathogen of the respiratory tract among schoolaged children and young adults. The incidence of CNS complication is reported as 0.1-7% of Mycoplasma pneumoniae infections. We experienced a case of cerebral infarction complicated by Mycoplasma pneumoniae, and reviewed the literature about the CNS complication of Mycoplasma pneumoniae infection.

  • Mycoplasmas are highly fastidious bacteria, difficult to culture and slow growing. Infections with Mycoplasma species can cause a variety of problems in living organisms and in vitro cell cultures. In this study, we investigated the usefulness of a genus-specific consensus PCR analysis method to detect Mycoplasma species. The developed consensus primer pairs MycoF and MycoR were designed specifically to amplify the 16S ribosomal RNA gene (rRNA) of Mycoplasma species by the optimized PCR system. The developed consensus PCR system effectively amplified 215 bp of Mycoplasma genus-specific region of 16S rRNA. In conclusion, we recommend this consensus PCR for monitoring Mycoplasma species in animals, human and cell culture system.

  • Approximately, 15-20% of all cancers worldwide are caused by infectious agents. Understanding the role of infectious agents on cancer development might be useful for developing new approaches to its prevention. Mycoplasma genitalium is a clinically important sexually transmitted pathogen that has been associated with several human diseases. There have been a few studies suggestive of probable roles of Mycoplasma genitalium in cancer development, including prostate and ovarian cancers and lymphomas, but the role of this microorganism like other Mycoplasma species in neoplasia is still conjectural. Considering the prevalence of Mycoplasma genitalium infections and also the emergence of resistant strains, Mycoplasma genitalium needs more attention in the infectious agent cancer-causing research area.

  • The economic impact of swine mycoplasma infection is high. An accurate diagnosis is often difficult and time consuming. We report the development and validation of an effective multiplex polymerase chain reaction (PCR) assay that detects Mycoplasma (M.) hyopneumoniae and M. hyorhinis. The multi detection of M. hyopneumoniae and M. hyorhinis primer set were employed to detect mycoplasma species and typing of the species was performed on the basis of sequence analysis of the PCR product. The target nucleic acid fragments were specifically amplified by M. hyopneumoniae and M. hyorhinis PCR with 16S ribosomal DNA primers. Single and mixed Mycoplasma species DNA templates were used to evaluate the specificity of the multiplex assay. The corresponding specific DNA products were amplified for each pathogen. The multiplex PCR assay provides a novel tool for simultaneous detection and differentiation of M. hyopneumoniae and M. hyorhinis.

  • The Guillain-Barre Sydrome (GBS) is post-infectious autoimmune disease and it could be caused by auto-antibodies produced after infections. Mycoplasma pneumoniae is one of rare cause of GBS and known to be associated with antibody to galactocerebroside (GalC) which is a major neutral glycolipid constituent of myelin. We report a case of GBS with immunoglobulin M GalC antibody after M. pneumoniae infection.

  • For recent years, use of autologous fat injection has increased significantly in facial contouring surgery. Along with such increase in use, complications like atypical mycoplasma infection have been also on the increasing trend. The authors report two cases of Mycobacterium chelonae infection that occurred after autologous fat injection. Patients were treated as infection that resistant to common antibiotics and results were negative to routine culture and Gram staining. Acid-fast bacillus stain, polymerase chain reaction (PCR) test and mycobacterial cultures were conducted for diagnosis under suspicion of atypical mycoplasma infection. Then, combination antibiotics therapy, surgical treatment, and steroid injection were performed for treatment. Both patients were diagnosed with Mycobacterium chelonae in PCR test. They were positive to mycobacterial cultures. Combination antibiotics therapy was repeated to improvement of symptom. However, they could not be free from side effects such as deformation in facial contour, scar and pigmentation even after full recovery. When chronic wound infections after autologous fat injection, we must suspect atypical or mycobacterial infection and conduct examinations for a early diagnosis and proper antibiotic therapy that is effective to the nontuberculous mycobacteria.

  • Various factors negatively affect poultry production, including a multitude of avian pathogens. Among them, Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) cause world-wide economic losses in the poultry industry. Although respectively, MG and MS induce chronic respiratory disease and synovitis in poultry, these pathogens often manifest as clinically inapparent infections and many countries are therefore having difficulties effectively eradicating them. In this study, five broiler breeder farms in Korea were investigated for the presence of Mycoplasma infection from 2016 to 2018. Serum samples were collected for detection of antibodies to mycoplasma species using an enzyme-linked immunosorbent assay (ELISA) kit. Additionally, the production index and feed conversion rate of broilers were recorded. According to this investigation, broiler breeder farms in 2018 were serologically negative for Mycoplasma infection with broilers exhibiting a high production index and low feed conversion rate. Thus, eradicating mycoplasma in poultry farms is critical for improving chick quality and overall poultry production.

  • The efficacy of berberine sulphate, a fluorochrome having binding properties with both DNA and RNA, was investigated for the detection of mycoplasma-like organisms(MLOs) in jujube(Zizyphus jujuba), paulownia(Paulownia tomentosa), mulberry(Morus alba) trees and periwinkle (Catharanthus roseus) plant. When examined under fluorescence microscope, berberine sulphate-stained sections of diseased samples showed distinct MLO-specific fluorescent particles in the phloem area, while such fluorescence was absent in the healthy ones. This staining technique was proved to be a very accurate method for the diagnosis of MLO infections in woody and herbaceous plants. Furthermore, the cheap and easy procedure could be used to test a great number of samples on MLO infections with reliability and rapidity.

  • Mycoplasma pneumoniae is a common cause of community-acquired pneumonia in children, with a peak incidence at 5-14 years. Extrapulmonary manifestations occur in 20-25% of patients with M. pneumoniae infection. Most auto-antibodies that cause immune hemolytic anemia in humans are cold agglutinins. The formation of cold agglutinins is frequently observed during M. pneumoniae infections, and cold agglutinin disease usually occurs during M. pneumoniae infections. Nevertheless, severe hemolysis is exceptional. If a patient has any underlying disease related to hemolysis, it is possible to accelerate hemolysis. Hereditary spherocytosis is a common cause of hereditary hemolytic anemia resulting from red blood cell membrane defects. Hemolysis of red cells may result from corpuscular abnormalities or extracorpuscular abnormalities, such as immune or non-immune mechanisms. We report a case of hereditary spherocytosis associated with severe hemolytic anemia due to Mycoplasma pneumonia.
