“…The clinical mastitic manifestation may include firm quarters, a sudden milk drop and failure of antimicrobial treatment. At the same time cows may not show any systemic signs in spite of the udder infection, although a mild mucoid discharge and arthritis may be present (Houlihan, Veenstra, Christian, Nicholas, & Ayling, ). These workers also observed abortions in the mastitic cows with M. bovis being detected in an aborted foetus.…”

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.

“…34 -36 In outbreaks with Mycoplasma mastitis, it is not unusual to find cases of Mycoplasma arthritis. [37][38][39][40][41] Similarly, a field outbreak of Mycoplasma-associated bovine respiratory disease was associated with outbreaks of arthritis. 41 The link between arthritic Mycoplasma disease events and mastitis or pneumonia is indicative that internal somatic spread of this agent is not uncommon.…”

“…Mycoplasma bovis uważana jest za czynnik etiologiczny wielu ważnych chorób bydła. Dotychczas wykazano, że zakażenia z udziałem tego zarazka wywoływać mogą zapalenie: płuc i oskrzeli (enzootyczna bronchopneumonia cieląt, syndrom oddechowy bydła, BRD), stawów, ucha środkowego, rogówki i spojówki, a także gruczołu mlekowego (6,8,11,14). Zakażenia M. bovis stanowią znaczący problem w odchowie bydła także z ekonomicznego punktu widzenia.…”

The object of the study was to evaluate the effect of an experimental vaccine against Mycoplasma bovis infections on selected humoral immune parameters in the calves. The study was carried out on twelve calves divided into two equal groups: experimental and control. The experimental calves were subcutaneously injected with experimental vaccine composed of suspension of the M. bovis field strain of with saponin and lysozyme. The control group was administered with PBS by the same route. Blood samples for laboratory analyses were collected from all the animals directly prior to the proper experiment (zero test), then at daily intervals up to the 7th day of observation and next at weekly ones up to the 12th week after the vaccination. Serum samples were examined for total bovine immunoglobulins (Ig) and their individual classes (IgG, A i M) using suitable ELISA kits. In response to the vaccine the total serum concentration of Ig was at first lower than in the control animals up to the 56th day of observation, then it increased up to the end of the study. A distinct stimulation of the IgG synthesis was observed in the experimental animals throughout the study with the exception of the 42nd and 77th days when it was slightly decreased. On the other hand the IgA concentration was considerably lower in the experimental calves when compared to the control up to the 7th day of observation, whereas it was visibly increased at day 63rd and 70th after the vaccination. In response to the vaccination the IgM concentration had comparable values to the control throughout the study with the exception of the 4th and 56th days when they were considerably higher, whereas the IgM decrease was observed only at the 21st day after the vaccination. The experimental vaccine composed of the field strain of M. bovis with saponin and lysozyme caused significant activation of selected indices of humoral immunity in the affected animals.
