spp. are facultative pathogens that contribute to the pathogenesis of multiple bovine diseases, including the bovine respiratory disease complex, and have been shown to form biofilms. Biofilm formation is associated with increased antibiotic resistance in many organisms, but accurate determination of antimicrobial susceptibility in biofilms is challenging.

() is characterized by a reduced genomic size and limited synthetic capacity, including the inability to synthesize nucleotides de novo, relies on nucleases for nutrient acquisition and survival. A number of nucleases have been implicated in pathogenicity, facilitating substrate degradation and contributing to DNA repair mechanisms that enhance bacterial persistence. The present study confirmed that the T5.

In vitro three-dimensional organoid models simulate key aspects of the structure and function of in vivo organs and have been used to study physiology, host-pathogen interactions, pathogenesis and pharmacodynamics. Although most organoid studies have been developed using human or mouse tissues, recent advancements have enabled the establishment of intestinal and respiratory tract organoids from domestic animal samples. Mycoplasma bovis causes chronic respiratory tract infections in cattle with significant health and economic consequences.

Article Synopsis
- - This study investigates Mycoplasma bovis (M. bovis) infection in cattle, which can cause various health issues, aiming to analyze the genetic diversity of M. bovis strains from clinical samples in Ireland and Scotland.
- - Researchers sequenced the genomes of 24 M. bovis strains (19 from Ireland and 5 from Scotland) and compared them to 117 existing genetic assemblies to create a phylogenetic tree, identifying Irish strains in two groups and all Scottish strains in one.
- - The findings highlight the similarities between Irish and Scottish M. bovis strains and underscore the importance of biosecurity in cattle management due to the global spread of this infection facilitated by international cattle movement.

Mycoplasma bovis has emerged as a significant pathogen in cattle, leading to considerable economic losses in the cattle industry. It is associated with various clinical syndromes, including pneumoniae, mastitis, and arthritis. The innate immune response, particularly macrophages, plays a crucial role in combating infections caused by such pathogens.
