Evaluation of Actinobacillus pleuropneumoniae diagnostic tests using samples from naturally and experimentally infected pigs
July 6, 2009By Simone Oliveira
The objective of this study was to compare the performance of different diagnostic tests for the detection of pigs subclinically infected with Actinobacillus pleuropneumoniae. To address this...
Diagnostic Characteristics of Oral Fluid for Detection of PRRS
March 13, 2009By Michael Murtaugh
Oral fluid sampling for health monitoring by assessment of antibody levels specific for pathogens is an exciting new concept in swine management. The work here shows that sampling of individual...
