Bayesian latent class models to determine diagnostic sensitivities and specificities of two point of care rapid tests (Selma plus, Dipslide) for the detection of associated with mastitis in dairy cows.

Introduction: Development and validations of accurate mastitis diagnostics are crucial to make timely and evidence-based decisions on mastitis therapy in order to reduce its impact on productivity, animal welfare and practicing the prudent use of antimicrobials on dairy farms.

Methods: The objectives of this study were to assess the agreement between test results from reference laboratory and two point of care tests (Selma plus, Dipslide) and to estimate the test accuracies with Bayesian latent class models (BLCMs). In total of 509 single quarter milk samples from cows with mastitis were included in the study.

Surgical debridement and primary closure of the oral mucosa for repair of open mandibular pars incisiva fractures in three neonatal calves.

Case Description: 3 neonatal female calves (ages, < 1 to 4 days) were examined because of mandibular trauma.

Clinical Findings: Physical examination indicated that each calf had an open fracture of the mandibular pars incisiva (rostral mandibular fracture) with ventral displacement of the incisors at the affected region. Oral radiographs were obtained for 1 calf and revealed that 5 incisors were fractured at the level of the apical dental buds.
