Outbreak of meningitis in weaner pigs caused by unidentified asaccharolytic gram-negative bacterium.
Several organisms are known to cause outbreaks of meningitis in pigs, with Haemophilus species being the most frequently implicated. We report such an outbreak in which necropsied pigs manifested an unusual combination of meningitis, tracheitis, and bronchitis. The causative agent appeared to be an asaccharolytic gram-negative nonfermentative bacterium whose classification has yet to be determined. The organism was isolated from the brain and was extremely capnophilic, growing in air only after several serial subcultures.
