Isolation of Salmonella spp from the environment of dairies without any history of clinical salmonellosis.

Objective: To determine whether Salmonella spp could be isolated from the environment of free stall dairies in Wisconsin without any history of clinical salmonellosis and determine the serotype and antimicrobial susceptibility of any Salmonella isolates recovered from the environment.

Design: Cross-sectional study.

Study Population: 20 free stall dairies with no history of clinical salmonellosis.

Management of pneumothorax in cattle by continuous-flow evacuation.

Pneumothorax in cattle can develop subsequent to acute or chronic pulmonary disease, and if unresolved may lead to respiratory distress and death due to hypoxia and compression and collapse of cardiac and thoracic great vessels. Therapeutic evacuation of free air within the pleural space can provide acute relief and improve chances of survival. This article descibes the adaptation and use of a continuous flow evacuation device to resolve pneumothorax in 3 cattle with pneumothorax associated with infectious lower airway disease.
