Mycoplasma pneumonia, caused by Mycoplasma bovis (Mycoplasmopsis bovis; M. bovis), is linked with severe inflammatory reactions in the lungs and can be challenging to treat with antibiotics. Biofilms play a significant role in bacterial persistence and contribute to the development of chronic lesions. A recent study has shown that polymicrobial interactions between species are an important factor in biofilm formation, yet the precise mechanism of biofilm formation in M. bovis remains unknown. By assuming multiple pathogen infections in the bovine respiratory disease complex (BRDC), this study examined the characterisation of the polymicrobial relationship between M. bovis and Trueperella pyogenes (T. pyogenes) during biofilm formation. Autopsies were performed on four Holstein calves (two chronic Mycoplasma pneumonia calves and two control calves). Bacterium-like aggregation structures (> 10 μm), which were assumed to be biofilms of M. bovis in vivo, were observed adhering to the cilia in calves with Mycoplasma pneumonia. M. bovis released an extracellular matrix to connect with neighbouring bacteria and form a mature biofilm on the plate. Biofilm formation in the co-culture of M. bovis and T. pyogenes (strain T1: 1 × 105 and 1 × 106 CFU/well) significantly increased (p < 0.05 and p < 0.01; 64.1% and 64.8% increase) compared to that in a single culture of these bacteria. Furthermore, some large aggregates (> 40 μm), composed of M. bovis and T. pyogenes, were observed. The morphological characteristics of this biofilm were similar to those observed in vivo compared to a single culture. In conclusion, the polymicrobial interaction between M. bovis and T. pyogenes induces biofilm formation, which is associated with increased resistance to antimicrobial agents, and this exacerbates the progression of chronic Mycoplasma pneumonia.

A case of urachal abscess resection via colpotomy in a cow Reviewed

Language：English Publishing type：Research paper (scientific journal) Publisher：JAPANESE SOCIETY OF VETERINARY SCIENCE
This study describes a novel surgical method to remove urinary bladder-related urachal abscesses in a cow. Traditional methods, such as the midline or paramedian approach in calves and the preinguinal approach, can be challenging in adult cattle, especially for lesions situated near the pelvic cavity. In this case, a 4-year-old cow had a urachal abscess attached to the bladder apex, making it difficult to approach via abdominal wall incision. Colpotomy and pulling the abscess through a vaginal wall incision allowed for complete exteriorization of the lesion and comfortable accessibility of the abscess and the resection site. This report suggests that colpotomy is an effective new route in adult cattle for accessing urachal abscesses not accessible via traditional surgical approaches.

牛マイコプラズマ肺炎の病態診断に関する研究
Grant number：15K18785 2015.04 - 2018.03
科学研究費補助金 若手研究(B)
Authorship：Principal investigator
牛マイコプラズマ肺炎は、主にMycoplasma bovisを原因菌とする感染症で、発症すると不可逆的な乾酪壊死性肺炎の経過をたどって廃用淘汰されるなど経済的損失が大きく、近年特に問題となっている。本病の最も大きな問題点は、①健常牛からもM. bovisが分離され発症が日和見的であること、②病態把握が難しく結果的に長期加療の上で廃用となるため、治療費、飼料代、労力などの経済的損失が大きいこと、③さらにその発症牛が農場内の感染源となり続けることがあげられる。この課題解決のために、１）牛マイコプラズマ肺炎の病態進行メカニズムの解明、２）M. bovis浸潤農場での易感染個体把握システムおよび発症個体の病態診断システムの開発を行い、最終的に、M. bovis浸潤農場における牛マイコプラズマ肺炎による損耗低減化のための飼養管理技術の開発を目指す。
