Conjunctivitis in the nude rat (rnu/rnu).

G J Moore

    Laboratory Animals
    |January 1, 1979
    PubMed
    Summary
    This summary is machine-generated.

    Nude rats can develop conjunctivitis and abscesses due to Pasteurella pneumotropica. Mild cases benefit from warm water eye washes, while severe infections require ampicillin treatment.

    Area of Science:

    • Veterinary Ophthalmology
    • Immunology
    • Microbiology

    Background:

    • Nude rats, like nude mice, exhibit susceptibility to ocular conditions.
    • Conjunctivitis leading to periorbital abscesses is a notable issue in these animals.
    • Pasteurella pneumotropica has been identified as a causative agent in conjunctival infections.

    Purpose of the Study:

    • To investigate the occurrence and management of conjunctivitis in nude rats.
    • To identify the microbial cause of ocular infections in nude rats.
    • To evaluate treatment efficacy for conjunctivitis in nude rats.

    Main Methods:

    • Observation of clinical signs in nude rats.
    • Isolation and identification of bacteria from conjunctival swabs.
    • Treatment protocols involving warm water irrigation and ampicillin administration.

    Related Experiment Videos

  • Comparison with a germ-free colony of nude rats.

    • Main Results:

    • Nude rats commonly suffer from conjunctivitis and periorbital abscesses.
    • Pasteurella pneumotropica was isolated from affected rats' conjunctiva.
    • Mild conjunctivitis responded to warm water flushing.
    • Severe cases showed improvement with ampicillin treatment.
    • Germ-free nude rats did not develop conjunctivitis.

    Conclusions:

    • Nude rats are prone to conjunctivitis caused by Pasteurella pneumotropica.
    • Topical ampicillin and supportive care are effective treatments.
    • Maintaining a germ-free environment prevents this ocular condition in nude rats.
