| field efficacy of porcilis® pcv m hyo versus a licensed commercially available vaccine and placebo in the prevention of prdc in pigs on a french farm: a randomized controlled trial. | a controlled, randomised, and blinded trial performed on a conventional french farrow-to-finish farm compared the efficacy of a one-shot bivalent ready to use vaccine, porcilis® pcv m. hyo (group pcvm), to that of two commercial vaccines (ingelvac® circoflex® + ingelvac® mhyo, group icim), and to a placebo (group ctl), in preventing the health and economic impacts of porcine respiratory disease complex (prdc). | 2017 | 28405459 |
| provision of straw by a foraging tower -effect on tail biting in weaners and fattening pigs. | straw is one of the most effective rooting materials to reduce tail biting in pigs. a so-called foraging-tower (ft) provides only small quantities of straw compatible with liquid manure systems. the focus of the present study was on the effect of providing straw by ft in order to prevent tail biting in tail docked pigs. four consecutive batches of 160 pigs, randomly divided into a straw (sg) and a control group (cg) were followed up from weaning to slaughter. | 2017 | 28405460 |
| the use of oral fluids to monitor key pathogens in porcine respiratory disease complex. | the usefulness of oral fluid (of) sampling for surveillance of infections in pig populations is already accepted but its value as a tool to support investigations of porcine respiratory disease complex (prdc) has been less well studied. this study set out to describe detection patterns of porcine reproductive and respiratory syndrome virus (prrsv), porcine circovirus type 2 (pcv2), swine influenza virus type a (siv) and mycoplasma hyopneumoniae (m. hyo) among farms showing differing severity of ... | 2017 | 28405463 |
| antimicrobial susceptibility monitoring of mycoplasma hyopneumoniae and mycoplasma bovis isolated in europe. | mycoplasma hyopneumoniae in pigs and mycoplasma bovis in cattle are major pathogens affecting livestock across europe and are the focus of the mycopath pan-european antimicrobial susceptibility monitoring programme. fifty m. hyopneumoniae isolates from belgium, spain and the united kingdom (uk), and 156 m. bovis isolates from france, hungary, spain and the uk that met specific criteria were tested for antimicrobial susceptibility in a central laboratory by using a microbroth dilution method. spe ... | 2017 | 28532800 |
| comparison of gene expression of toll-like receptors and cytokines between piau and commercial line (landrace×large white crossbred) pigs vaccinated against pasteurella multocida type d. | we aimed to compare toll-like receptors (tlr) and cytokines expression in local piau breed and a commercial line (landrace×large white crossbred) pigs in response to vaccination against pasteurella multocida type d. seronegative gilts for pasteurella multocida type d and mycoplasma hyopneumoniae were used, from which peripheral blood mononuclear cells (pbmc) were collected in four time points (t0, t1, t2 and t3; before and after each vaccination dose). for bronchoalveolar lavage fluid cells (bal ... | 2017 | 28554143 |
| metabolic modeling of energy balances in mycoplasma hyopneumoniae shows that pyruvate addition increases growth rate. | mycoplasma hyopneumoniae is cultured on large-scale to produce antigen for inactivated whole-cell vaccines against respiratory disease in pigs. however, the fastidious nutrient requirements of this minimal bacterium and the low growth rate make it challenging to reach sufficient biomass yield for antigen production. in this study, we sequenced the genome of m. hyopneumoniae strain 11 and constructed a high quality constraint-based genome-scale metabolic model of 284 chemical reactions and 298 me ... | 2017 | 28600895 |
| mycoplasma hyopneumoniae vaccination at or shortly before weaning under field conditions: a randomised efficacy trial. | this study assessed the efficacy of two different mycoplasma hyopneumoniae vaccination programmes in relation to the time of weaning. eight hundred and twenty-eight piglets were randomly divided into three groups: group v1 was vaccinated three days before weaning, group v2 at weaning (21 days of age) and group nv was left non-vaccinated. vaccinations were performed using ingelvac mycoflex. after the nursery period, 306 pigs were allocated to fattening unit (f1) and 501 pigs to a second unit (f2) ... | 2017 | 28601840 |
| occurrence of mycoplasma hyorhinis infections in fattening pigs and association with clinical signs and pathological lesions of enzootic pneumonia. | respiratory disorders in fattening pigs are of major concern worldwide. particularly enzootic pneumonia remains a problem for the pig industry. this chronic respiratory disease is primarily caused by mycoplasma hyopneumoniae (m. hyopneumoniae). however, more recently it was hypothesised that m. hyorhinis can also cause similar lung lesions. to investigate the relevance of m. hyorhinis as a cause of pneumonia in fattening pigs 10 farms in switzerland (considered free of enzootic pneumonia) and 20 ... | 2017 | 28619130 |
| comparison of sample types and diagnostic methods for in vivo detection of mycoplasma hyopneumoniae during early stages of infection. | detection of mycoplasma hyopneumoniae in live pigs during the early stages of infection is critical for timely implementation of control measures, but is technically challenging. this study compared the sensitivity of various sample types and diagnostic methods for detection of m. hyopneumoniae during the first 28days after experimental exposure. twenty-one 8-week old pigs were intra-tracheally inoculated on day 0 with m. hyopneumoniae strain 232. two age matched pigs were mock inoculated and ma ... | 2017 | 28619131 |
| detection of mycoplasma hyopneumoniae in naturally infected gilts over time. | mycoplasma hyopneumoniae causes a chronic respiratory infection in pigs and its transmission occurs mainly by direct contact and by vertical transmission (sow-to-piglet). the objective of this study was to assess the detection dynamics and persistence of m. hyopneumoniae natural infection in replacement gilts. forty-four twenty-day-old gilts were selected from a m. hyopneumoniae positive farm and followed up to one day prior to their first weaning. laryngeal swabs were collected every 30days, st ... | 2017 | 28619147 |

| microbiome overview in swine lungs. | mycoplasma hyopneumoniae is the etiologic agent of swine enzootic pneumonia. however other mycoplasma species and secondary bacteria are found as inhabitants of the swine respiratory tract, which can be also related to disease. in the present study we have performed a total dna metagenomic analysis from the lungs of pigs kept in a field condition, with suggestive signals of enzootic pneumonia and without any infection signals to evaluate the bacteria variability of the lungs microbiota. librarie ... | 2017 | 28719637 |
| detection and phylogenetic analysis of mycoplasma hyopneumoniae from tibetan pigs in western china. | enzootic pneumonia (ep), often caused by mycoplasma hyopneumoniae, occurs in tibetan pigs between october and december in western china. the aim of this study was to determine the prevalence of m. hyopneumoniae in tibetan pig herds and also the prevalence of infection. m. hyopneumoniae was detected using enzyme-linked immunosorbent assay, polymerase chain reaction (pcr), and 16s rrna sequencing. twenty-nine inflammatory gross-lesions were observed in 155 lungs of slaughtered pigs. invasion of fo ... | 2017 | 28741040 |
| determinants for swine mycoplasmal pneumonia reproduction under experimental conditions: a systematic review and recursive partitioning analysis. | one of the main mycoplasma hyopneumoniae (m. hyopneumoniae) swine experimental model objectives is to reproduce mycoplasmal pneumonia (mp). unfortunately, experimental validated protocols to maximize the chance to successfully achieve lung lesions induced by m. hyopneumoniae are not available at the moment. thus, the objective of this work was to identify those factors that might have a major influence on the effective development of mp, measured as macroscopic lung lesions, under experimental c ... | 2017 | 28742802 |
| mycoplasma hyopneumoniae detection in nylon-flocked and rayon-bud swabs. | the objective of this study was to compare the absorption and m. hyopneumoniae detection by real-time pcr using nylon-flocked and rayon-bud swabs. results of this study showed that absorption and detection of m. hyopneumoniae were significantly higher in nylon-flocked swabs with ct differences only ranging from 0.5 to 1.7. | 2017 | 28807761 |
| update on mycoplasma hyopneumoniae infections in pigs: knowledge gaps for improved disease control. | mycoplasma hyopneumoniae (m. hyopneumoniae) is the primary pathogen of enzootic pneumonia, a chronic respiratory disease in pigs. infections occur worldwide and cause major economic losses to the pig industry. the present paper reviews the current knowledge on m. hyopneumoniae infections, with emphasis on identification and analysis of knowledge gaps for optimizing control of the disease. close contact between infected and susceptible pigs is the main route of m. hyopneumoniae transmission. mana ... | 2017 | 28834294 |
| efficacy of one dose vaccination against experimental infection with two mycoplasma hyopneumoniae strains. | mycoplasma hyopneumoniae (m. hyopneumoniae) is the primary agent of enzootic pneumonia in pigs. pigs are often infected with different m. hyopneumoniae strains. this study assessed the efficacy of vaccination against experimental infection with two genetically different m. hyopneumoniae strains in weaned piglets. at 33 days of age (d0), 45 m. hyopneumoniae-free piglets were randomly assigned to three different groups: 1) negative control group (ncg; n = 5): not vaccinated, not infected, 2) posit ... | 2017 | 28851359 |
| etiology of acute respiratory disease in fattening pigs in finland. | the objective of our study was to clinically and etiologically investigate acute outbreaks of respiratory disease in finland. our study also aimed to evaluate the clinical use of various methods in diagnosing respiratory infections under field conditions and to describe the antimicrobial resistance profile of the main bacterial pathogen(s) found during the study. | 2017 | 28852568 |
| survey on mycoplasma hyopneumoniae gilt acclimation practices in europe. | gilts are considered to play a key role in mycoplasma hyopneumoniae (m. hyopneumoniae) transmission and control. an effective gilt acclimation program should ideally reduce m. hyopneumoniae shedding at first farrowing, decreasing pre-weaning colonization prevalence and potential respiratory problems in fatteners. however, information on gilt acclimation practices is scarce in europe. the aim of this study was to identify current acclimation strategies for m. hyopneumoniae in europe using a quest ... | 2017 | 28852569 |
