Abstract

Two outbreaks of salmonellosis in guinea pigs (Cavia porcellus), arc referred in a total of 70 animals maintained in animal facility, that showed loss of weigh, dullness, high body temperature and rough dull hair coat. Death occurred in 48.57% (34/70) a few days after showing the clinical signs. Fragments of liver, spleen, kidneys, lungs and intestines were collected during necropsy. The isolated colonies were characterized biochemically and serologically as Salmonella typhimurium. The histopathological findings in the fragments stained by hematoxilin-eosin agreed with septicaemic condition. The present investigation shows the risk of carrier animals used in experimental trials to interfere with the obtained results; besides those animals represent a source of infection of this zoonosis in animal facilities and laboratories.
