Macroscopic lesions may include fibrinous peritonitis, broad multifocal mamillary necrosis and widespread intersitial pneumonia. Most organs are susceptible to ''L. monocytogenes''. Microscopic histopathology may include monocytic perivascular cuffing in brain tissues.

Two species of ''Yersina'' have been isolated from chinchillas; ''Y. pseudotuberculosis'' and ''Y. enterocolitica''.

===Iatrogenic (Antibiotics)===
The administration of inappropriate antibiotics such as lincomycin, cephalosporins, penecillins or amoxicillins may result in a decrease in the usual gram-positive gut flora and an increase in gram-negative bacteria causing enterotoxaemia. ''Clostridium perfringens'' is the most common gram-negative causative agent of enterotoxaemia. Clinical signs will include emaciation, diarrhoea, lethargy, dehydration and if untreated, death.
