[Giardiasis in guinea pigs: a case report]

Area of Science:

• Veterinary Pathology
• Parasitology
• Laboratory Animal Medicine

Background:

• Giardia species are protozoan parasites that can infect various hosts.
• Guinea pigs are common laboratory animals, and their health is crucial for research.

Observation:

• During quarantine, several guinea pigs exhibited weakness and lethargy, with one succumbing.
• Microscopic examination of affected animals revealed a high burden of Giardia species in the duodenum.
• Intestinal tissues showed mild inflammation and cystic enlargement of duodenal and jejunal crypts.

Findings:

• The presence of numerous Giardia organisms, coupled with characteristic histopathological changes, confirmed the diagnosis.
• Absence of other significant pathogens supported Giardia as the primary cause of morbidity and mortality.

Implications:

• This study highlights giardiasis as a potential health concern in guinea pig populations.
• Understanding Giardia's impact is vital for maintaining the health and welfare of laboratory guinea pigs.
• Effective diagnostic and management strategies for guinea pig giardiasis may be warranted.
