“…Related to parturition, a recent publication raised awareness of the ability of M. bovis to cause infected seromas in multiple animals following Caesarean section. Despite intensive antimicrobial therapy with multiple antimicrobials, only one of six infected animals was successfully treated (Gille et al., ).…”

There is a worldwide problem of disease caused by Mycoplasma (M.) bovis in cattle; it has a significant detrimental economic and animal welfare impact on cattle rearing. Infection can manifest as a plethora of clinical signs including mastitis, pneumonia, arthritis, keratoconjunctivitis, otitis media and genital disorders that may result in infertility and abortion. Current diagnosis and control information are reviewed and analysed to identify gaps in knowledge of the causative organism in respect of the disease pathology, diagnosis and control methods. The main considerations are as follows: no vaccines are commercially available; antimicrobial resistance is increasing; diagnostic and antimicrobial sensitivity testing needs to be improved; and a pen-side test would facilitate more rapid diagnosis and implementation of treatment with antimicrobials. More data on host susceptibility, stress factors, immune response and infectious dose levels are required. The impact of asymptomatic carriers, M. bovis survival in the environment and the role of wildlife in transmitting the disease also needs investigation. To facilitate development of vaccines, further analysis of more M. bovis genomes, its pathogenic mechanisms, including variable surface proteins, is required, along with reproducible disease models.

De keizersnede is een routine-ingreep voor dierenartsen in de Vlaamse rundveepraktijk. Alhoewel de ingreep wordt aangeleerd volgens een standaardprotocol, blijkt uit eerder onderzoek dat het antibioticumgebruik bij deze indicatie sterk varieert tussen dierenartsen. In deze studie werd door middel van een vragenlijst getracht een beeld te schetsen van wanneer welke antibiotica gebruikt worden en in welke mate dit overeenstemt met de aanbevelingen van het kenniscentrum “Antimicrobial Consumption and Resistance in Animals” (AMCRA). Uit de resultaten blijkt dat alle respondenten antibiotica gebruiken tijdens de ingreep. Negentien percent dient ook standaardantibiotica toe kort na de operatie. Penicilline wordt in 52% van de gevallen als eerste keuze ingezet, wat overeenstemt met de AMCRA-richtlijnen. Het overige deel van de respondenten (48%) opteert voor breedspectrumantibiotica, zoals penicillineneomycine, penicilline-dihydrostreptomycine, lincomycine-spectinomycine, die volgens AMCRA tweedekeuzemiddelen zijn. Voor wat betreft de intramusculaire behandelingen vóór en na de ingreep, behandelt slechts 35% overeenkomstig de referentiedosering voor een koe tussen de 600 en 800 kg. Er wordt vooral ondergedoseerd bij behandelingen na de ingreep en bij nabehandeling. Op basis van de evaluatie van het tijdstip van behandelen en de antibioticumkeuze blijkt dat slechts 23% van de respondenten handelt in overeenstemming met de voorschriften van het AMCRA-formularium. Uit deze resultaten kan besloten worden dat het gebruik van antibiotica tijdens een nietgecompliceerde keizersnede sterk varieert en slechts tot op zekere hoogte overeenkomt met wat door AMCRA wordt aanbevolen. Onvoldoende kennis van de richtlijnen kan hier aan de basis liggen. Een betere communicatie is dan ook een eerste en belangrijke stap om de bewustwording te verbeteren.

“…LG2 originated from a milk sample from a cow with mastitis, arthritis, and an infected seroma (Gille et al, 2016). Mycoplasma bovis species identification was confirmed by use of real-time PCR targeting the uvrC gene of filter-cloned isolates (Rossetti et al, 2010).…”

“…It is generally accepted that the most important route of M. bovis introduction onto a farm consists of purchase of a carrier (Fox, 2012). Sperm can be infectious (Pfützner and Sachse, 1996), and recent work suggests the possibility of between herd spread through fomites or persons (Gille et al, 2016).…”

Mycoplasma bovis is an important cause of mastitis in dairy cattle, and pneumonia, arthritis, and otitis in calves. Milk and colostrum are considered important sources of infection for calves. knowledge on the effect of on-farm freezing (-18°C) and thawing methods on the recovery of M. bovis from colostrum samples is missing. In this study, 2 separate experiments were performed. The first experiment consisted of a longitudinal study examining the survival [as measured by log(10) reduction] of 2 M. bovis strains in frozen colostrum over 14 wk. The second experiment examined the effect of different thawing temperatures (45 and 20°C), thawing frequencies (once or twice), and initial colostrum titer (10 or 10 cfu/mL) on M. bovis survival. A single freeze-thaw cycle led to an approximate 1 log reduction of M. bovis titer, independent of the thawing temperature. Freezing for 14 wk did not significantly further reduce the titer of bacteria compared with freezing for 2 wk. A second freeze-thaw cycle further reduced the M. bovis count by approximately 0.5 log compared with a single freeze-thaw cycle. Thawing temperature and initial bacterial concentration did not significantly affect M. bovis reduction. In conclusion, storage of colostrum samples in the freezer at -18°C during epidemiological studies, herd monitoring, or test and cull programs will probably have little influence on qualitative bacteriological test results for M. bovis. The epidemiological or clinical relevance of an approximate 1 log reduction of M. bovis in colostrum is currently unclear.
