Several mycoplasma species are known to glide on solid surfaces such as glass in the direction of the membrane protrusion, but the mechanism underlying this movement is unknown. To identify a novel protein involved in gliding, we raised monoclonal antibodies against a detergent-insoluble protein fraction of Mycoplasma mobile, the fastest glider, and screened the antibodies for inhibitory effects on gliding. Five monoclonal antibodies stopped the movement of gliding mycoplasmas, keeping them on the glass surface, and all of them recognized a large protein in immunoblotting. This protein, named Gli521, is composed of 4,738 amino acids, has a predicted molecular mass of 520,559 Da, and is coded downstream of a gene for another gliding protein, Gli349, which is known to be responsible for glass binding during gliding. Edman degradation analysis indicated that the N-terminal region is processed at the peptide bond between the amino acid residues at positions 43 and 44. Analysis of gliding mutants ...
Mycoplasma suis, a member of the hemotrophic mycoplasma (HM) group, parasitize erythrocytes of pigs. Increasing evidence suggests that M. suis is also a zoonotic agent. Highly pathogenic strains of M. suis (e.g., M. suis KI3806) have been demonstrated to invade erythrocytes. This complete sequenced and manually annotated genome of M. suis KI3806 is the first available from this species and from the HM group. The DNA was isolated from blood samples of experimentally infected pigs due to the lack of an in vitro cultivation system. The small circular chromosome of 709,270 bp, encoding an unexpectedly high number of hypothetical proteins and limited transport and metabolic capacities, could reflect the unique lifestyle of HM on the surface of erythrocytes. ...

Mycoplasma haemofelis (formerly Haemobartonella felis) is a gram negative epierythrocytic parasitic bacterium. It often appears in bloodsmears as small (0.6μm) coccoid bodies, sometimes forming short chains of 3 to 6 organisms. It is usually the causative agent of Feline Infectious Anemia (FIA) in the United States. The ~1.15 Mb genome contains a minimalistic assortment of genes limited to the most basic cellular functions. This leaves M. haemofelis inextricably dependent upon its host for the provision of amino acids, cholesterol, vitamins, and fatty acids. The complex and specific conditions the bacterium requires have made it impossible to culture outside a host thus far. Arthropod vectors are thought to be the primary source of infection, although M. haemofelis is also known to be transmitted from queen to kitten and following blood transfusion. Immunocompromization and/or coinfection with FeLV, FIV, and other Mycoplasma species can exacerbate symptoms or cause symptoms to arise in ...
Protocol:. Remove culture medium from vessels, wash cells and detach cells using Trypsin/EDTA (#GTC02.0100) or Accutase®(#GTC01.0100). Count cells and cultivate in fresh medium supplemented with Mycoplasma Removal Reagent (1ml per 50ml of culture medium) and cultivate for 2 to 3 days according to normal procedure. Mycoplasma Removal includes 3 or more passages. It is highly recommended to check cultures weekly for mycoplasma contamination (e.g. by ELISA, cultivation, or Fluorescence staining). Normally, mycoplasma contamination should be removed after 2 or 3 weeks. If required, repeat treatment with increased Mycoplasma Removal Reagent (1ml per 40ml, 1ml per 30ml, 1ml per 25ml).. Note:. Presence of Mycoplasma can also be detected by PCR. However, it should be taken into account that PCR cannot distinguish between living and dead cells, and thus that one might obtain false positive results.. ...
There are currently 8 complete genome sequences, and 4 that are in progress. (click [Organism:exp here] for the NCBI genome list for Mycoplasma). Mycoplasma genitalium is thought to have the smallest genome of any self-replicating organism, measuring only 580,070 bp long with just 470 open reading frames. Its overall G+C content is 32%. The regions of lowest G+C content are around the origin of replication. The genome of Mycoplasma pneumoniae is much longer at 816 kbp, containing 209 open reading frames in the additional 236 kbp, giving it a total of 679 open-reading frames. Mycoplasma hyopneumoniae 232 is 892,758 bp long with G+C content of 28.6 mol%. It has 53 ORFs and is the largest family is the 34-member ABC transporter family. Mycoplasma mobile 163K is 777,079 bp long with 517 ORFs and has one of the lowest DNA G+C contents of 24.9% and most reduced set of tRNAs of any organism yet reported.

Strains of Eperythrozoon wenyonii are cell-wall-less uncultivated parasitic bacteria that attach to the surface of host erythrocytes. 16S rRNA gene sequence has been determined for this species and phylogenetic analysis shows that this haemotrophic bacteria is closely related to species in the genus Mycoplasma Nowak 1929 (Approved Lists 1980) [1, 2]. To reflect this phylogenetic affiliation, Neimark et al. 2001 [2] propose that Eperythrozoon wenyonii be transferred to the genus Mycoplasma as Candidatus Mycoplasma wenyonii. Publication: Anonymous.

Mycoplasma contaminations have a multitude of effects on cultured cell lines that may influence the results of experiments or pollute bioactive substances isolated from the eukaryotic cells
Mycoplasma suis belongs to haemotrophic mycoplasmas (HMs) which cause infectious anaemia in a large variety of mammals. To date, no in vitro cultivation system for M. suis or other HMs has been established. We hypothesised that M. suis could grow in classical Mycoplasma media supplemented with nutrients (e.g. glucose, iron-binding proteins) which are naturally available from its host environment, the porcine blood. Blood from experimentally M. suis-infected pigs was used to inoculate either standard SP-4 Mycoplasma medium supplemented with iron-binding proteins (transferrin, haemin, and haemoglobin) or glucose-enriched Hayflick Mycoplasma medium. A quantitative M. suis-specific real-time PCR assay was applied to determine and quantify M. suis loads weekly during 12 week-incubation. The first 2 weeks after inoculation M. suis loads decreased remarkably and then persisted at a stationary level over the observation time of 12 weeks in iron-binding protein- or glucose supplemented media variants. ...

Isolation of T strain mycoplasmas was found to be directly related to sexual activity in three groups of women. Metabolic inhibition titers followed the same pattern, the number of titers increased with sexual activity. The rate of mycoplasma isolations from the urine of asymptomatic males was lower in statistically significant levels than the rate of mycoplasma isolations from patients attending the genitoinfectious disease clinic. Nonspecific urethritis due to T strain mycoplasmas is a discrete entity which can be diagnosed in the initial office visit. Normal sexually active controls without prior history of urethritis have only an 18% incidence of positive T strain cultures, whereas patients with nonspecific urethritis range from 60%-70% positive T strain mycoplasma cultures in a urethral washout urine specimen.

Colon cancer: In a study to understand the effects of mycoplasma contamination on the quality of cultured human colon cancer cells, it was found that there is a positive correlation between the amount of M. hyorhinis present in the sample and the percentage of CD133 positive cells (a glycoprotein with an unknown function). Further tests and analysis are required to determine the exact reason for this phenomenon.[27] Gastric cancer: There are strong indications that the infection of M. hyorhinis contributes to the development of cancer within the stomach and increases the likelihood of malignant cancer cell development.[28] Lung cancer: Studies on lung cancer have supported the belief that there is more than a coincidental positive correlation between the appearance of Mycoplasma strains in patients and the infection with tumorigenesis. Because this is a such a new area of research, more studies must be performed to further understand the correlation and determine possible preventative steps for ...

Mycoplasma is very difficult to treat because many commonly used antibiotics do not work well. Penicillin, Polyflex®, Naxcel®, Excenel®, and Excede® kill bacteria by destroying the cell wall. Since Mycolplasma does not have a normal cell wall, these antibiotics are ineffective in treating it. Micotil® shows little or no activity against Mycoplasma as well.. Oxytetracycline (the active ingredient in LA-200®, Biomycin 200®, Tetradure 200®, and other generics) has produced mixed results in treating Mycoplasma. In one study 50 percent of M. bovis isolates were resistant to oxytetracycline. Tulathromycin (Draxxin®) is the only drug approved for Mycoplasma, and in one study, was the drug most likely to be effective (Godinho, et al., 2005). Draxxin® provides the most convenient treatment of Mycoplasmosis because one dose provides seven to 14 days of therapeutic blood concentrations against Mycoplasma and Mannheimia haemolytica, Pasturella multocida, and Histophilus somni, all causes of BRDC. ...
Most, if not all, CFS/ME patients have multiple chronic bacterial and viral infections.73-80 For example, when patients were examined for evidence of multiple, systemic bacterial and viral infections, the Odds Ratio for this was found to be 18 (CI 95% 8.5-37.9, p, 0.001).75 In this study CFS/ME patients had a high prevalence of one of four Mycoplasma species (Odds Ratio=13.8, CI 95% 5.8-32.9, p, 0.001) and often showed evidence of co-infections with different Mycoplasma species, C. pneumoniae (Odds Ratio=8.6, CI 95% 1.0-71.1, p, 0.01) and HHV-6 (Odds Ratio=4.5, CI 95% 2.0-10.2, p, 0.001).75 In a separate study the presence of these infections was also related to the number and severity of signs and symptoms in CFS/ME patients, including neurological symptoms.77 Similarly, Vojdani et al.76 found Mycoplasma species in a majority of CFS/ME patients, but this has not been seen in all studies.81 Interestingly, when European CFS/ME patients were examined for various Mycoplasma species, the most common ...
If a cell line is found to be infected with mycoplasma, the recommended procedure is to discard and replace it with clean cultures, but if the culture cannot be replaced it is possible to attempt to eliminate the infection, even if this is a time-consuming and often unsuccessful exercise, and the risk exists that other cultures become contaminated during the treatment. At Banca Biologica the contaminated cells are treated either with Mycoplasma Removal Agent, or with cyprofloxacin or BM-Cyclin. After treatment, the cells are regularly tested for mycoplasma contamination for at least four weeks, and they are considered cleaned if the results of all assays remain negative along this period ...
MYCOPLASMA. Mycoplasma are single cell organisms similar to bacteria, and are the smallest free-living, self-replicating organisms known. Unlike bacteria that have a rigid cell wall, Mycoplasma have thin, flexible membranes, which contain its cytoplasma. This lack of a cell wall allows Mycoplasma to resist many of the antibiotics that are useful against most bacteria. Mycoplasma are difficult to detect in human and animal specimens and difficult to culture in the laboratory ...
Evaluation of the identities of over 500 cell lines from external customers shows that the incidence of intraspecies CC is ~10% while the incidence of interspecies CC is ~6%. These results highlight the need for a standard authentication procedure for cell line identity and purity testing. Researchers using transgenic animal technology utilize various rodent cell lines. The most relevant cell lines for the biotechnology industry, BHK-21 and CHO, were derived from Syrian and Chinese hamsters, respectively. Thus, the cell status should be frequently examined under the inverted microscope. 2. After passaging, test the cultures for mycoplasma contamination. If the cells are clean, freeze and store aliquots in liquid nitrogen. The cells in active culture have to be retested periodically to ensure continued freedom from mycoplasma contamination (see Note 7). C. G. Drexler 3.

SUMMARY: Alteration of the tonicity of a modified Edward medium by means of NaCl or other solutes resulted in very marked effects on the growth of several Mycoplasma strains. With both fluid and solid media, all grew best at about 10 atmospheres osmotic pressure (water activity, aw , 0.9925). The most exacting species, Mycoplasma gallisepticum, failed to grow outside the range 6.8-14 atmospheres (aw 0.995-0.990), while the least exacting, M. laidlawii, multiplied at up to 27 atmospheres (aw 0.980. Osmotic requirements were not appreciably altered by serial growth in hypertonic or hypotonic media but were, to some extent, conditioned by the serum content of the medium.
Results Spectacular transcript changes after M. arginini contamination were noted in GM13509 as compared to control cells after the first 72 h of incubation, ie inflammatory response gene transcripts significant decrease, especially of CD36 (from FC = 7.91 in control to −97.86 in mutated cells) and similarly of IL8 (141.26; −244), CBS (86.55; 21.68) and AQP9 (58.66; 2.59). The most increase of SLC1A2 (122.89; 143.20) transcript related to energy metabolism was discerned.. However, Antigen CD19 presentation and the EBV copy number in both contaminated cell lines were reduced more effectively than in uncontaminated cells. More increase of M. arginini amount during 2-week co-culture was observed in cells with HTT mutation. ...

Several mycoplasma species are known to glide about solid surfaces such as glass in the direction of the membrane protrusion, but the mechanism underlying this movement is usually unknown. concentration of ATP (9). was isolated from your gill organ of a fish (13). It provides an opportunity to study mycoplasma gliding motility, because this varieties is the fastest gliding and, unlike additional varieties, glides without interruption (9, 21, 24, 27, 34). Whatsoever stages of growth, glides efficiently and continually on glass at an average rate of 2.0 to 4.5 m/s or three to seven times the space of the cell per second, exerting a force of Rabbit Polyclonal to FCRL5. up to 27 pN (21). Subcellular localization of surface proteins recognized by monoclonal antibodies suggested the cell surface is definitely differentiated into three parts, head, throat, and body, starting from the pole of protrusion (16).

Mycoplasma haemocanis has not been successfully grown in agar or cell cultures due to its fastidious growth requirements. Traditionally, diagnosis relied on microscopic identification of organisms attached to the surfaces of erythrocytes in Wright-Giemsa-stained peripheral blood smears. However, this method not only lacks sensitivity but also is not adequately specific because the morphology of M. haemocanis can easily be confused with other microorganisms such as rickettsia. Molecular detection by PCR is the most sensitive and specific way of detecting M. haemocanis in the blood of infected dogs having both acute and latent infections, even during challenge with immunosuppressive drugs which would prevent detection by serological techniques. ...

Mycoplasma. Mycoplasma refers to a family (also known as a genus) of bacteria that lack a cell wall. This means that common antibiotics such as penicillin, or other cell wall synthesis (the combination of several entities to form something different (such as the process by which amino acids form proteins, or proteins form an organelle)) targeting antibiotics (also known as beta-lactam antibiotics). They can be parasitic (living off other organisms) or saprotrophic (living off dead or decomposing matter).. Mycoplasma in Chickens. The most common type of mycoplasma affecting chickens is mycoplasma gallisepticum. This type of mycoplasma is parasitic, and affects chickens, wild birds, turkeys, pigeons and other fowl. It is the causative agent of chronic respiratory disease (CRD) in chickens and infectious sinusitis in game birds, turkeys, pigeons etcetera. It is transmitted either through the eggs of carrier hens, or by chicken to chicken (airborne) transmission. It is highly contagious and is ...

INTRODUCTION. The genus Mycoplasma (Mollicutes order) forms a group of bacteria which are obligate parasites of several species of animals and are associated with anemia, arthritis, infertility and respiratory disorders (Chalker 2005, Willi et al 2007). Generically called mycoplasmas, they have a very small genome and are devoid of a cell wall. Among the pathogenic species, the hemotrophic mycoplasmas (haemoplasmas) are receiving more attention in recent years due to increased infections in human patients, especially those with compromised immune systems (Santos et al 2008). They are characterised by parasitism of the surface of erythrocytes of different mammalian species in which they cause anemia with variable intensity, from asymptomatic cases to the potentially fatal (Chalker 2005, Willi et al 2007).. M. haemocanis, previously Haemobartonella canis, and Candidatus M. hematoparvum are associated with anemia in dogs (canine hemoplasmosis), but the establishment of more severe clinical cases ...

Worlds first synthetic cells: J Craig Venter Institute (JCVI) via BBC News. Later Venters lab distinguished itself by building a small bacteriums genome with man-made DNA fragments, piece by piece - another milestone. It was both milestone achievements that, combined, led the team to the synthetic cell disclosed today. The researchers started out by combining two small species of Mycoplasma with a chemically synthesized goat germ genome, and finally transplanted that into a living cell from a different Mycoplasma species. The team encountered an obstacle here and they eventually had to spell check (!) the DNA fragments of the synthetic genome to make sure there were no errors. The delay in the achievement of their goal was about three months, but finally, they learned the spell checker found a typo in the genetic code!. Once it was fixed, the synthetic DNA and its cytoplasm, having been tagged to distinguish it from the DNA of the natural Mycoplasma, started to produce its own proteins. ...

Mycoplasma gallisepticum (MG) is a bacterium belonging to the class Mollicutes and the family Mycoplasmataceae. It is the causative agent of chronic respiratory disease (CRD) in chickens and infectious sinusitis in turkeys, chickens, game birds, pigeons, and passerine birds of all ages. Mycoplasmosis is the infection of Mycoplasma bacteria. Mycoplasmas have many defining characteristics. Mycoplasma lack cell walls, have highly variable surface proteins and a distinctive plasma membrane, and are the smallest self-replicating prokaryotes. Mycoplasma can cause disease in humans, animals, insects, and plants. Mycoplasma attach to host epithelial cells, such as in the respiratory tract, which causes cell damage and inflammatory response. There are currently over 100 species of Mycoplasma known. The following have been isolated from wild birds: Mycoplasma buteonis, Mycoplasma corogypsi, Mycoplasma falconis, Mycoplasma gypis, Mycoplasma sturni, and Mycoplasma gallisepticum. M. gallisepticum has the ...

N2 - Two canine haemoplasma species have been recognised to date; Mycoplasma haemocanis (Mhc), which has been associated with anaemia in splenectomised or immunocompromised dogs, and Candidatus Mycoplasma haematoparvum (CMhp), recently described in an anaemic splenectomised dog undergoing chemotherapy. The study aim was to develop quantitative real-time PCR assays (qPCRs) incorporating an endogenous internal control to detect Mhc and CMhp and to apply these assays to DNA samples extracted from canine blood collected in ...
Mycoplasma species may persist as part of the normal human flora of the respiratory system or the genital area. Of seven known mycoplasma species from the genital area, so far only four have been described as pathogenic: Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum und Ureaplasma parvum.. Mycoplasma hominis (M. hominis) mainly colonizes the genital tract of sexually active men and women, however most of the M. hominis described infections have been diagnosed in woman. M. hominis is associated with pelvic inflammatory disease (PID) and may cause infections during or after pregnancy, such as endometritis or neonatal pneumonia. Common symptoms for infections with M. hominis include e.g. frequent urination, yellow discharge or dysuria.. Globally, the prevalence of Mycoplasma genitalium (M. genitalium) ranges between 1- 4 % for men and 1 - 6.4 % for women. In men, M. genitalium may result in non-specific urethritis and is the second most common cause after Chlamydia trachomatis. ...
Introduction: The bacterium Mycoplasma capricolum subsp. capricolum is known as a pathogen in goats. There have been no reports on a zoonotic potential so far. Case presentation: A case of septicaemia and meningoencephalitis in a 62-year-old patient has been associated with infection by M. capricolum subsp. capricolum. No other infectious agent could be detected. Conclusion: Although it was impossible to identify the source of infection, coincidental contact with small ruminants or consumption of food products from goats during a tourist trip may have played a role ...

Mycoplasma pneumoniae is a major cause of bacterial pneumonia in the United States. Outbreaks of illness due to mycoplasma commonly occur in closed or semi-closed communities. These outbreaks are difficult to contain due to delays in outbreak detection, the long incubation period of the bacterium, and an incomplete understanding of the effectiveness of infection control strategies. This article introduces a novel mathematical approach to studying the spread and control of a communicable infection such as mycoplasma, in a closed community. The model explicitly captures the patterns of interactions among patients and caregivers in an institution with multiple wards. Analysis of this contact network predicts that despite the relatively low prevalence of mycoplasma pneumonia found among caregivers, the patterns of caregiver activity and the extent to which they are protected against infection may be fundamental to the control and prevention of mycoplasma outbreaks.
MYCOPLASMA: The Linking Pathogen in Neurosystemic Diseases Several strains of mycoplasma have been engineered to be more dangerous. They are now blamed for Adult-onset Asthma, AIDS, CFS, MS, RA and other diseases. Dr Maurice Hilleman, chief virologist for the pharmaceutical company Merck Sharp & Dohme, has stated that this disease agent is carried by everybody in North America and possibly most people throughout the world.. Pathogenic MYCOPLASMA Patent U.S. Patent #5,242,820 states that Mycoplasma fermentans incognitus is implicated in:. AIDS, Chronic Fatigue Syndrome. Alzheimers Disease. Wegeners Disease. Sarcoidosis. respiratory distress syndrome (asthma). Kikuchis disease. autoimmune diseases such as Collagen Vascular Disease and Lupus. M. fermentans incognitus may be either a causative agent or a key co-factor in these diseases. Particulate Matter and Mycoplasma Stress Interactions ...
Many lipoproteins are expressed on the surfaces of mycoplasmas, and some have been implicated as playing roles in pathogenesis. Family 2 lipoproteins of Mycoplasma plleumoniae have a conserved mycoplasma liM poprotein X central domain and a mycoplasma lipoprotein 10 CMterminal domain and are differentially expressed in response to environmental conditions. Homologues of family 2 lipoproteins are Mycoplasma specific and include the lipoprotein of Mycoplasma gaIlisepticum, encoded by the MGA0674 gene. Comparative transcriptomic analysis of the M. gaUisepticum live attenuated vaccine strain F and the virulent strain Rio,, reported in this study, indicated that MGA0674 is one of several differentially expressed genes. The MGA0674M encoded lipoprotein is a proteolytically processed, immunogenic, TXM114 detergentMphase protein which apM pears to have antigenic divergence between field strains R10w and S6. We examined the virulence of an R10w AMGA0674 mutant (PIH9) in vivo and observed reduced ...

Mycoplasma ovipneumoniae NCTC 10151(T) and four new isolates from UK sheep flocks were compared. Only glucose and pyruvate were used as energy sources by the five strains: glucose was the best energy source for the type strain, pyruvate supported better growth of the new strains. Whole cell protein patterns and antigenic profiles showed high similarity between all five strains. The new isolates fell into two groups in ELISA tests. Serum samples from 30 pneumonic sheep were assessed for M. ovipneumoniae infection and Mycoplasma arginini co-infection. Fourteen (out of 30) serum samples were positive for M. ovipneumoniae both by ELISA and immunoblotting. Twelve antigenic proteins of M. ovipneumoniae were detected in infected serum samples: the antigen patterns were unique, with between one and at least seven occurring in any one sample. All serum samples were designated as negative for M. arginini antibodies by both ELISA and immunoblotting. (c) 2007 Elsevier Ltd. All rights reserved.. ...
The pentose phosphate pathway is a process of glucose turnover that produces NADPH as reducing equivalents and pentoses as essential parts of nucleotides. There are two different phases in the pathway. One is irreversible oxidative phase in which glucose-6P is converted to ribulose-5P by oxidative decarboxylation, and NADPH is generated [MD:M00006]. The other is reversible non-oxidative phase in which phosphorylated sugars are interconverted to generate xylulose-5P, ribulose-5P, and ribose-5P [MD:M00007]. Phosphoribosyl pyrophosphate (PRPP) formed from ribose-5P [MD:M00005] is an activated compound used in the biosynthesis of histidine and purine/pyrimidine nucleotides. This pathway map also shows the Entner-Doudoroff pathway where 6-P-gluconate is dehydrated and then cleaved into pyruvate and glyceraldehyde-3P [MD:M00008 ...
Summary T-mycoplasmas were isolated from the semen of 23 of 28 bulls at an A.I. Centre, and from the semen of each of 4 bulls on separate farms. Washings from the preputial cavities of 10 bulls each contained at least 105 organisms per ml. In all, T-mycoplasmas were isolated from either semen or the preputial cavities of 28 of 34 bulls examined. Although the organisms were isolated from semen, they were not isolated from testicular tissue, the vas deferens or the mucosal scrapings of the urethra of 2 slaughtered bulls. It seems that the mycoplasmas are confined to the preputial cavity and gain access to semen during ejaculation. It is suggested that the failure of the organisms to become established in other areas of the genital tract is due to the presence of a potent mycoplasma inhibitor that was detected in bull semen in this study. A similar inhibitor was found in bull serum. It is thermostable at 56°C and nondialysable. The ecology and pathological role of the T-mycoplasmas in cattle are discussed
Mycoplasma species are the smallest free-living organisms. These organisms are unique among prokaryotes in that they lack a cell wall, a feature largely responsible for their biologic properties such as their lack of a reaction to Gram stain and their lack of susceptibility to many commonly prescribed antimicrobial agents, including beta-lact...

Mycoplasma infections are of great concern in avian medicine, because they cause economic losses in commercial poultry production of Pakistan. Timely and efficient diagnosis of the mycoplasma is needed in order to practice prevention and control strategies. A duplex Polymerase Chain Reaction (PCR) was optimized for simultaneous detection of two pathogenic species of avian mycoplasmas. Two sets of oligonucleotide primers specific for Mycoplasma gallisepticum and Mycoplasma synoviae, were used in the test. The developed assay exhibited high sensitivity and 100% specificity for the simultaneous detection of mycoplasma species prevalence in Pakistan ...

Most Danish pig herds are infected with Mycoplasma hyosynoviae, a bacterium that causes acute arthritis in pigs older than approx. 10 weeks of age. No effective prophylaxis is available. Therefore the aim of this project is to develop a vaccine with the potential to protect against arthritis caused by M. hyosynoviae. This is done through screening of the immunogenic effect of different antigen preparations in combination with different adjuvants. Immunogenic effects of vaccine candidates are evaluated by their ability to induce both serological and cell-mediated immune response. The two most promising antigen/adjuvant combinations obtained in the screening are tested as vaccine candidates in infection studies in pigs. Finally - if the protective effect of a vaccine candidate turns out to be satisfying - it will be tested in a controlled field study. An effective vaccine administered to pigs at risk would reduce the acute disease problems in herds with severe outbreaks of M. hyosynoviae ...
Several mycoplasma species have been shown to form biofilms that confer resistance to antimicrobials and which may affect the host immune system, thus making treatment and eradication of the pathogens difficult. The present study shows that the biofilms formed by two strains of the human pathogen Mycoplasma pneumoniae differ quantitatively and qualitatively. Compared with strain UAB PO1, strain M129 grows well but forms biofilms that are less robust, with towers that are less smooth at the margins. A polysaccharide containing N-acetylglucosamine is secreted by M129 into the culture medium but found in tight association with the cells of UAB PO1. The polysaccharide may have a role in biofilm formation, contributing to differences in virulence, chronicity and treatment outcome between strains of M. pneumoniae. The UAB PO1 genome was found to be that of a type 2 strain of M. pneumoniae, whereas M129 is type 1. Examination of other M. pneumoniae isolates suggests that the robustness of the biofilm ...
Have you ever brought new birds into your established flock and discovered that the new birds or your own flock become sick after a week or two of placing the two groups together? The disease culprit might be infection with Mycoplasma organisms, either Mycoplasma gallisepticum (MG) or Mycoplasma synoviae (MS). This organism is one you should become familiar with and guard against its introduction to your flock.. Mycoplasma organisms are smaller than bacteria and have no protective cell wall, making it necessary that they attach very closely to the birds respiratory tract cells. When they attach, they cause damage to those cells, which alters the birds ability to fight infection. Mucus in the windpipe normally functions to move disease organisms the bird might breathe upward through the windpipe and out of the birds respiratory tract. After exposed to mycoplasma, this no longer works effectively. The mucus becomes thicker and less able to flow upward. In addition, the Mycoplasma can damage the ...

Polymerase Chain Reaction Test. Information is not generally available about this agent because, first of all, the mycoplasma is such a minutely small disease agent. A hundred years ago, certain medical theoreticians conceived that there must be a form of disease agent smaller than bacteria and viruses. This pathogenic organism, the mycoplasma, is so minute that normal blood and tissue tests will not reveal its presence as the source of the disease.. Your doctor may diagnose you with Alzheimers disease, and he will say: Golly, we dont know where Alzheimers comes from. All we know is that your brain begins to deteriorate, cells rupture, the myelin sheath around the nerves dissolves, and so on. Or if you have chronic fatigue syndrome, the doctor will not be able to find any cause for your illness with ordinary blood and tissue tests.. This mycoplasma couldnt be detected until about 30 years ago when the polymerase chain reaction (PCR) test was developed, in which a sample of your blood is ...

The adsorption of mycoplasma virus P1, a virus which infects some strains of Mycoplasma pulmonis, to host cells was examined. Mutants of M. pulmonis to which P1 virus did not adsorb were isolated. Proteins from the mutants and from wild-type cells were compared by two-dimensional polyacrylamide gel electrophoresis, and the only observed difference was in the surface antigen V-1. The electrophoretic properties of V-1 also correlated with the host range of the virus. These data strongly suggest that the V-1 antigen affects adsorption of P1 virus to host cells ...
