Mutations in the VP2 gene of rotavirus associated with benzimidazole sensitivity.

Rotavirus species A (RVA) is the etiological agent of acute gastroenteritis in young individuals of various animal species, including humans. Vaccination has helped to reduce the impact of these viruses on humans and some species of domestic mammals, but they do not confer complete immunity, so antirotavirus agents are another important control option. In this study, millimolar concentrations of benzimidazole inhibited the replication of the Rhesus rotavirus (RRV) strain of RVA.

Outbreak of Systemic Avian Pox in Canaries () Associated with the B1 Subgroup of Avian Pox Viruses.

This study reports an outbreak of avian pox in a quarantine of canaries imported from Europe, with a mortality of 30% and clinical signs of dyspnea and blepharoconjunctivitis. During necropsy, beak cyanosis, serous blepharitis, caseous sinusitis, oropharyngitis, tracheitis, pulmonary edema, pneumonia, fibrinous airsacculitis, and splenomegaly were observed. Microscopically, edema, epithelial hyperplasia, hydropic degeneration, and vacuolated eosinophilic intracytoplasmic inclusion bodies were found; similar lesions were observed in the thymus, spleen, and other organs.

First Identification of Chlamydia psittaci in the Acute Illness and Death of Endemic and Endangered Psittacine Birds in Mexico.

A mortality episode of endemic and endangered psittacine birds from the genera Ara and Amazona occurred during January 2015. The birds were housed in a management unit for wildlife conservation that receives wild-caught birds from illegal trade. In total, 11 (57%) adult birds of different origins that shared these accommodations died.
