The Genome Sequence of Mycoplasma mycoides subsp. mycoides SC Type Strain PG1T, the Causative Agent of Contagious Bovine Pleuropneumonia (CBPP). Genome Research 14:221-227, 2004. Mycoplasma is a genus of bacteria which lack cell walls. Mycoplasma mycoides is divided into two colony types (large and small) based on their growth and biochemical characteristics. The large colony types (LC) are known to grow larger in broth and mycoplasma agar as well as survive longer at 45 degrees, but are not found to be the cause of CBPP (contagious bovine pleuropneumonia). The LC type was first isolated in pure culture on sheep blood agar plates with lung specimens from a goat. The growth characteristics were of four known LC types, and five known SC types were compared on the sheep blood agar at 2, 5, and 7 days.  The SC types were not visible at 2 days and did not grow larger than 0.1 mm, whereas the LC types were visible in 2 days.
Some mycoplasmas are particularly suspicious bacteria for involvement in oncogenesis. Although most are extracellular, some invade eukaryotic cells (16) and have been associated with some human.. . The main differences between the two are: (1) Mycoplasma are independent microbes and L-type bacteria are variants of normal bacterial cells that have a cell wall (most L-type cells will revert to their original form when the induction factor is eliminated); (2) Mycoplasma growth requires cholesterol (10–20% serum in the medium) while the growth of L-type bacteria does not; (3) L-type bacteria fade easily after Diane staining, while Mycoplasma do not fade easily.
Mycoplasma usually colonize the throat, bacterial biofilm, or tartar found in the oral cavity. Mycoplasma pneumoniae is one of the common causes of acute respiratory infections. Although previous studies reported that Mycoplasma can be separated from root canal infections, gingivitis, and periodontitis clinical specimens, the distribution and pathogenicity in the oral cavity are still unclear. What is Mycoplasma pneumoniae? Mycoplasma pneumoniae is a small bacterium which causes atypical pneumonia in young adults Typical colonies of the Mycoplasma are omelet-like in shape. Colony diameter is about 10–15 μm, the center is round, opaque, and extends into the medium, and the edge of the colony is thin and flat, forming a transparent or semitransparent area. Other characteristic colonies of the Mycoplasma include mulberry-shaped colonies of M. pneumoniae. Mycoplasma from the mouth and saliva form visible comet-like colonies in semisolid medium (mostly in the middle and bottom of the culture medium). Meaning of Mycoplasma medical term.

Human infections with Mycoplasma spp. that infect animals have been reported predominantly in immunocompromised patients91 and in individuals in whom trauma and wound contamination have occurred.1 Because these infections appear to be uncommon, routine attempts to recover Mycoplasma spp. are not warranted. However, in unusual circumstances, such as an immunocompromised patient with negative results on routine bacterial cultures or a patient with an infected wound after a seal bite, culture for Mycoplasma spp. should be considered. “Seal finger,” an infection known to occur in seal hunters and wildlife workers, results from seal bites or from skinning or handling seals.1,92,93 Several different species of marine mycoplasma found in mouths and respiratory tracts of seals are the presumed cause.

Waites KB. New concepts of Mycoplasma pneumoniae infections in children. Pediatr Pulmonol. 2003 Oct. 36(4):267-78. [Medline]. Researchers estimate that more than 2 million cases of M pneumoniae infections occur annually. M pneumoniae causes approximately 20% of community-acquired pneumonias that require hospitalization and an even greater proportion of those that do not require hospitalization. M pneumoniae may exist endemically in large urban areas. Epidemics occur every 3-7 years, with the incidence varying considerably from year to year. Slow spread throughout households is common, with a mean incubation period of 20-23 days. Disease tends to not be seasonal, except for a slight increase in late summer and early fall.

The events described in steps 2, 3, and 4 can actually proceed in cycles and, therefore, amplify the outcome of all the steps. Altogether, these result in a prolonged, rather than overwhelming, deleterious effect of the mycoplasmas on the host cell, making this model of mycoplasma pathogenesis more attractive since it may explain the chronic nature of mycoplasma diseases.M pneumoniae infections occur both endemically and in cyclic epidemics in Japan and several European countries, similar to what occurs in the United States. Less information is available for tropical or polar countries; however, based on seroprevalence studies, the disease also occurs in these regions, suggesting that climate and geography are not important determinants in the epidemiology of M pneumoniae infections.

Mycoplasmas son los organismos más pequeños capaces de auto-reproducirse. Son bacterias desprovistas de pared celular, difíciles de cultivar. Pertenecen a la Clase Mollicutes(del latín: piel blanda), Orden Mycoplasmatales, Género Mycoplasma y Ureaplasma Микоплазмы - это мельчайшие свободноживущие прокариотические организмы, симбионты животных и растений. Они представляют собой своеобразную группу микроорганизмов, выделенную в класс Mollicutes, порядок Mycoplasmatales, семейство Mycoplasmataceae, делящееся на 2 рода, наиболее значимых в патологии человека - Mycoplasma и Ureaplasma.Fred R. Rurangirwa,1* Patrick S. Shompole,1 Anderson N. Wambugu,2 and Travis C. McGuire1. Clin Diagn Lab Immunol. 2000 May; 7(3): 519–521. Mycoplasmas are short rods (10 × 200 nm) that have no cell wall and are bounded by a sterol-containing membrane; thus, they are unaffected by cell wall–inhibiting antimicrobials such as β-lactams. In tissue culture, mycoplasmas are intracellular, but in vivo, infection is primarily extracellular and affects epithelial cells and their organelles, such as cilia. Attachment to respiratory epithelium is by way of terminal adhesin proteins. Mycoplasmas are active in stimulating several components of the immune system. They can act as polyclonal T-cell and B-cell activators and can cause capping of lymphocytes.Mycoplasmas from human sources are the most prevalent group and account for approximately one third to half of all strains isolated. Generally M. orale, which is the most common mycoplasma species in the oral cavity of clinically healthy humans, also represents the single most common isolate. Other non-pathogenic mycoplasma species from the normal human microbial flora of the oropharynx that are seen in cell cultures are M. fermentans and M. hominis. As the largest percentage of mycoplasma found in cell cultures are of human origin, it appears to be apparent that the laboratory personnel is directly involved and represents the major source of contamination.
Sixteen Mycoplasma species are found in humans, but not all may cause human disease. Learn about the many health complications of infection, plus treatment and prevention methods, here Mycoplasmas are grown in Roux bottles containing Hayflick's modified Edward's medium for about 48 hours at 37°C. Only glass-adherent mycoplasmas should be used for an AIA inoculum. It is therefore recommended that the stock be prepared from cultures which show only a slight indicator change from red to orange if phenol red is used as an indicator. The whole supernatant should be removed and the glass-adherent mycoplasmas should be washed with room temperature-equilibrated PBS solution. The mycoplasmas which still adhere to the glass are harvested with a cell scraper in 100 ml of fresh mycoplasma medium and are stored at −70°C in 1-ml aliquots for further use. Mycoplasma (my-ko-PLAZ-muh) infections are caused by a type of very small bacteria.

Mycoplasmas can cause oxidative damage to host cells. By this pathogenic mechanism, the adhering mycoplasmas produce, or induce the cell to produce, reactive oxygen molecules or free radicals. The proximity between the adhering mycoplasmas and the host cells allows the reactive oxygen, which usually has a short half-life, to reach and affect the host cell. The subject has been reviewed by Tryon and Baseman (1992) so only the basics will be summed up here. Many studies suggest that the initial stages of mycoplasma adherence and pathogenesis include the following steps:CBPP is predominantly a disease of cattle of the genus Bos. However, some breeds are more susceptible to the disease than others. In general, European breeds tend to be more susceptible than indigenous African breeds. Is it also known to cause severe disease in goats as well. CBPP affects many developing countries and is widespread in most of Africa and some parts of Asia, especially India and China. There have been periodic outbreaks within the last decade in Spain, Portugal, and Italy. However, since the nineteenth century CBPP has been eradicated in the United States.  Symptoms of acute CBPP involve respiratory distress, cough, confusion, anorexia, and pain in the affected side. Though close contact is required for transmission, the disease is spread by inhalation of bodily fluids from an infected animal. Outbreaks usually begin as the result of movement of an infected animal into an inexperienced herd. The mortality rate is quite varied and ranges from 10 to 70 percent.  Mycoplasma mycoides use a variety of potential virulence factors, including genes encoding for variable surface proteins and enzymes. Transport proteins responsible for the production of hydrogen peroxide and the capsule sre believed to have toxic effects on the animal.

Variation in CARDS toxin production among M pneumoniae strains may be correlated with the range of severity of pulmonary disease observed among patients.  The organism also has the ability to exist and possibly replicate intracellularly, which may contribute to chronicity of illness and difficult eradication.  Additionally, acute mycoplasmal respiratory tract infection may be associated with exacerbations of chronic bronchitis and asthma.  More extensive information on the pathogenesis of mycoplasmal respiratory infections is available in review articles and book chapters. [7, 1, 6]

The genome of Mmymy SC type strain PG1T has been sequenced to map all the genes in order to further the studies regarding cell function of the organism and to better understand CBPP. The genome consists of a single circular chromosome of 1,211,703 bp. It has the lowest G+C content (24 mole%) so far out of all the sequenced bacteria reported, and the highest density of insertion sequences (13% of the genome size). The genome contains 985 putative genes, of which 72 are part of insertion sequences and encode transposases.

Mycoplasma mycoides subsp. mycoidesSC (MmymySC; small colonies) is best known as the cause of bovine contagious pleuropneumonia (CBPP), a highly destructive disease in bovine cattle and goats, and is severe enough that it is included as the only bacterial disease in the World Organization for Animal Health's A-list of prioritized communicable animal diseases. Its genome has been completely sequenced in order to help promote the advancement of new vaccines, drugs, and diagnostic tools for CBPP. It is also the first genome that has been sequenced in the Spiroplasma group of the mollicutes, and the information will help in the study of the evolution of the mollicutes.

The P1 adhesin and other accessory proteins mediate attachment, followed by induction of ciliostasis, local inflammation that consists primarily of perivascular and peribronchial infiltration of mononuclear leukocytes, and tissue destruction that may be mediated by liberation of hydrogen peroxide. Recently, M pneumoniae has been shown to produce an exotoxin that is also believed to play a major role in the damage to the respiratory epithelium that occurs during acute infection.  This toxin, named the community-acquired respiratory disease toxin (CARDS) is an ADP-ribosylating and vacuolating cytotoxin similar to pertussis toxin.  Mycoplasma contamination is one of the most common and serious problems in culturing eukaryotic cells because it alters the phenotypic characteristics of the cells and can negatively impact results

MycoAlertTM Mycoplasma Detection Kit (10 Tests). Catalog #: LT07-118. Simple and fast detection of mycoplasma contamination in cell cultures using the first generation MycoAlertTM Mycoplasma.. As the term walking pneumonia implies, the great majority of M pneumoniae respiratory tract infections are mild and self-limited, although administration of antimicrobials hastens clinical resolution. Hospitalization is sometimes necessary, but recovery is almost always complete and without sequelae. Studies have indicated that M pneumoniae is second only to Streptococcus pneumoniae as a cause of bacterial pneumonia that requires hospitalization in elderly adults.  Subclinical infections may occur in 20% of adults infected with M pneumoniae, suggesting that some degree of immunity may contribute to the failure of clinical symptoms in some instances.  Mycoplasma have high nutritional demands and can grow on PPLO agar with beef heart infusion and 10–20% horse serum. The serum provides Mycoplasma with the cholesterol and long-chain fatty acids required for growth. The optimum pH for Mycoplasma culture is pH 7.8–8.0. Cells may die when the pH drops below pH 7.0.
