===Enteritis===
====Salmonellosis====
The bacteria ''Salmonella enterica'' has been shown to cause enteritis in gerbils along with food deprivation. Clinical signs include moderate to severe diarrhoea, a rough coat, weight loss, depression and dehydration. Morbidity and mortality are higher in younger animals. Transmission is associated with food or bedding contaminated by insects and/or other gerbils.

Macroscopic pathological findings will include a congested liver and distension within the gastrointestinal tract. The liver may display multifocal necrogranulomatous hepatitis. Some of the larger hepatic granulomas may display mineralisation of the necrotic centres. There may also be a fibrinosuppurative or fibrinopurulent peritonitis. The spleen may contain patchy pulmonary haemorrhage. Microscopic findings will include a positive culture of ''Salmonella'' species.

====Listeriosis====
Listeriosis in gerbils is characterised by acute death without clinical signs.

<br />
Macroscopic lesions include necrosuppurative hepatitis, enterocolitis, splenitis and hepatic and mesenteric lymphadenitis. There may also be diffuse acute pneumonitis.
