| seroprevalence and risk factors of mycoplasma suis infection in pig farms in central china. | mycoplasma suis, the causative agent of porcine infectious anemia, causes large economic losses to the swine industry worldwide. a questionnaire-based survey was conducted in 69 pig farms in hubei province, china, from november 2011 to august 2013 to ascertain the prevalence and associated risk factors of m. suis. four thousand and four blood samples from pigs of all the age groups were tested for m. suis antibodies using the established rmsg1-elisa assay. among these 4004 samples, 1615 blood sa ... | 2014 | 25081945 |
| quantitative pcr analysis of mycoplasma suis shedding patterns during experimental infection. | the uncultivable hemotrophic bacterium mycoplasma suis causes infectious anemia in pigs worldwide. the mechanisms by which m. suis is transmitted from pig to pig are largely unknown. thus, the present study aimed at investigating urine, feces, saliva, nasal and vaginal secrets as well as environmental samples for the presence of m. suis dna to get insights into potential transmission routes. seven pigs were experimentally infected with m. suis ki3806. samples were taken for 8 days post infection ... | 2014 | 25037994 |
| clinical and haematological characterisation of mycoplasma suis infections in splenectomised and non-splenectomised pigs. | mycoplasma suis causes infectious anaemia in pigs (iap), which can manifest in various degrees of severity depending on the virulence and the host's susceptibility. as m. suis cannot be cultured in vitro experimental infections of splenectomised animals play an essential role for pathogenesis research. the aim of the present study was to characterise the course of experimental infection using the highly virulent and red blood cell (rbc-) invasive m. suis strain ki3806, to compare the experimenta ... | 2014 | 24933162 |

| nanotransformation of the haemotrophic mycoplasma suis during in vitro cultivation attempts using modified cell free mycoplasma media. | 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 stan ... | 2012 | 22682998 |
| prevalence of swine hemoplasmas revealed by real-time pcr using 16s rrna gene primers. | hemoplasma is a tribal name for epierythrocytic mycoplasmas including mycoplasma suis and m. parvum which are currently recognized in pigs as causative of porcine hemoplasmosis. here, we report a real-time pcr assay for differential detection of these swine hemoplasma species by using allelic primers in the16s rrna gene, and its application to survey for hemoplasma infections in pigs. universal primers and species-specific primers were designed and evaluated by using swine blood samples positive ... | 2012 | 22673723 |
| insights into the gene expression profile of uncultivable hemotrophic mycoplasma suis during acute infection, obtained using proteome analysis. | hemotrophic mycoplasmas, bacteria without cell walls whose niche is the erythrocytes of their hosts, have never been cultivated in vitro. therefore, knowledge of their pathogenesis is fundamental. mycoplasma suis infects pigs, causing either acute fatal hemolytic anemia or chronic low-grade anemia, growth retardation, and immune suppression. recently, the complete genomes of two hemotrophic mycoplasma species, m. suis and m. haemofelis, were sequenced, offering new strategies for the analysis of ... | 2012 | 22267506 |
