Nasal dermatitis in the Mongolian gerbil.

J F Bresnahan, G D Smith, R H Lentsch

    Laboratory Animal Science
    |June 1, 1983
    PubMed
    Summary

    Nasal dermatitis affected 18.5% of Mongolian gerbils in Colony A and 3.7% in Colony B. Staphylococcus saprophyticus was linked to early nasal lesions in these rodents.

    Area of Science:

    • Veterinary Dermatology
    • Rodent Health
    • Microbiology

    Background:

    • Nasal dermatitis is a common condition in Mongolian gerbils.
    • Understanding its prevalence and contributing factors is crucial for colony health management.

    Purpose of the Study:

    • To determine the prevalence of nasal dermatitis in two Mongolian gerbil breeding colonies.
    • To identify factors associated with nasal lesions and the role of bacterial isolates.

    Main Methods:

    • Prevalence assessment across two distinct breeding colonies.
    • Correlation analysis with clinical signs (sex, tail barbering, epilepsy, dermatitis, alopecia, eye membrane protrusion).
    • Histopathological examination of nasal tissues and bacterial culture (Staphylococcus aureus, Staphylococcus saprophyticus).

    Main Results:

    • Colony A had a 18.5% prevalence (56/302), Colony B had 3.7% (2/54).
    • Nasal lesions correlated with forepaw dermatitis, periocular alopecia, and nictitating membrane protrusion.
    • Histopathology revealed acanthosis, hyperkeratosis, and dermal inflammation; Staphylococcus saprophyticus was associated with early lesions.

    Conclusions:

    • Nasal dermatitis prevalence varies significantly between gerbil colonies.
    • Specific clinical signs and Staphylococcus saprophyticus are associated with nasal dermatitis in Mongolian gerbils.
