An acute Actinobacillus pleuropneumonia challenge was used to study changes in rectal and radiant surface temperatures over 18 h. From 3.5 to 15 h after challenge, rectal temperatures were elevated in challenged pigs compared to nonchallenged controls. From 6 through 18 h after challenge, infrared surface temperature was higher for challenged pigs versus control nonchallenged pigs. Correlation coefficient analysis indicated that surface temperature and rectal temperature were moderately correlated. These results indicate that infrared thermography will detect changes in body surface temperature associated with the acute phase febrile response and has potential as a diagnostic tool for assessing systemic changes in radiant heat production.; Swine Day, Manhattan, KS, November 18, 1999
