MEGA11 Molecular Evolutionary Genetics Analysis Version 11

Koichiro Tamura et al.

Summary: MEGA software, a mature tool for computational molecular evolution, has been enhanced with new additions for building timetrees of species, pathogens, and gene families using rapid relaxed-clock methods. These additions include methods for estimating divergence times, confidence intervals, and new options for tagging sequences with spatiotemporal sampling information. The enhancements aim to improve user experience, result quality, and the pace of biological discovery.

Association between clinical respiratory signs, lung lesions detected by thoracic ultrasonography and growth performance in pre-weaned dairy calves

Inmaculada Cuevas-Gomez et al.

Summary: This study found that thoracic ultrasonography can detect lung consolidation in calves that show no signs of respiratory disease. Severe lung lesions were associated with reduced pre-weaning growth. These findings highlight the importance of using TUS in addition to clinical respiratory scoring of calves for early and accurate detection of clinical and sub-clinical BRD.
