, a Gram-positive facultative intracellular pathogen, is one of the most important causes of disease in foals between 3 weeks and 5 months of age. has also emerged as a common opportunistic pathogen in immunocompromised people, especially those infected with the human immunodeficiency virus ( ). Infection in both foals and people is most commonly characterized by life-threatening pyogranulomatous pneumonia, but extrapulmonary infections are also common ( ). In foals, extrapulmonary disorders might occur concurrent with or independent of pneumonia, and some foals have multiple extrapulmonary disorders concurrently ( ). Because ultrasonographic screening for early detection has become routine practice at many farms endemic for pneumonia caused by , the most frequently recognized form of infection on those farms is a subclinical form in which foals develop sonographic evidence of peripheral pulmonary consolidation or abscessation without manifesting clinical signs ( ).
