“…The confirmation of identification to species-level using 16S rRNA sequencing of bacterial isolates was shown to be the best approach. In this study two organisms (Actinobacillus equuli and Actinobacillus lignieresii) were cultured from the healthy group that have been reported in human infections associated with horse bites, (Moore et al 2003). These isolates have the potential to cause respiratory infections and bite wounds in humans, especially equine veterinary personnel who have close contact with horses.…”

The study of periodontal disease as part of equine dentistry is one of the overlooked fields of study, which truly needs more study and research to clearly understand the nature of the disease, the most appropriate diagnostic technique and prevention or treatment to provide for a good quality of life for horses.The abattoir survey of the oral cavity and dentition of 400 horses from SouthEast Queensland, Australia, showed that the most common dental abnormality was sharp enamel points (55.3% prevalence). Several types of dental abnormalities were strongly associated with age. The highest frequency of dental abnormalities (97.5%) were observed in senior horses (11-15 years old) and this included periodontal disease that increased to almost fifty percent in senior horses. The findings also confirmed that all horses, not just young horses, should have regular complete dental examinations as early as possible which should limit the development of more severe dental pathologies later in life.The equine oral microbiome found in dental plaque can cause oral disease which involves the some of the endogenous oral microbiota becoming opportunistic pathogens. The conventional method of oral microbiology based on culture dependent techniques usually overestimates the significance of species that are easily grown and overlooks microbial community diversity. Recently, the culture independent techniques using the next generation sequencing (NGS) method can determine the whole bacterial microbiota. The results from culture dependent and NGS method of analysis of healthy gingiva and periodontitis samples showed that the most common Genera isolated were Prevotella and Porphyromonas without a statistical significance in bacterial diversity, between the control and periodontitis groups. In conclusion, equine bacterial diversity between the healthy and periodontitis groups were similar which is different from other animals and this may be due to factors such as dentition, feed type and husbandry.The standard approach for diagnosis of equine periodontal disease (EPD) is based on clinical dental examination but to evaluate the current stage of disease and for further treatment planning, auxiliary aids such radiography are required. Equine dental radiography has been largely restricted to extraoral techniques by the standard equine radiography technology and the complexity of equine head anatomy. In III addition, superimposition and distortion of the cheek teeth arcade is a major problem for radiographic interpretation. Intraoral radiography has been largely ignored in horses, due to the uncooperative nature of these patients and the absence of dedicated technology unsuitable for equine oral radiography. In this study, radiographic images from seven horse heads obtained using a commercially available equine intraoral computed radiography system (IO-CR) and 3D imaging from computed tomography file sets were reviewed. IO-CR has shown potential as a diagnostic tool where key pathological lesions of EPD of the cheek teeth were demon...
