Epizootic streptococcal pneumonia in captive coyotes.

N L Gates, J S Green

    Journal of Wildlife Diseases
    |October 1, 1979
    PubMed
    Summary

    A bacterial infection caused severe death loss in captive coyotes. Streptococcus equisimilis led to acute broncho-pneumonia and pleuritis, resulting in a 46% mortality rate in one kennel.

    Area of Science:

    • Veterinary Pathology
    • Wildlife Disease Ecology
    • Bacteriology

    Background:

    • Captive wildlife populations can be susceptible to disease outbreaks.
    • High mortality events in zoological or research settings require prompt investigation.
    • Canine respiratory diseases can have significant impacts on animal welfare.

    Purpose of the Study:

    • To investigate the cause of severe mortality in a captive coyote population.
    • To identify the etiological agent responsible for broncho-pneumonia and pleuritis.
    • To document the pathological findings associated with the disease outbreak.

    Main Methods:

    • Necropsy and histopathological examination of deceased coyotes.
    • Bacteriological culture and isolation from affected tissues.
    • Clinical case reporting and epidemiological data collection.

    Main Results:

    • A mortality rate of 46% (22 out of 48) was observed within a 7-day period.
    • Postmortem examinations revealed acute fibrinopurulent broncho-pneumonia and pleuritis.
    • Streptococcus equisimilis was successfully isolated from the lung tissues of affected coyotes.

    Conclusions:

    • Streptococcus equisimilis is identified as the likely cause of the acute bacterial pneumonia and pleuritis outbreak.
    • The findings highlight the potential for rapid disease spread and high mortality in captive coyote populations.
    • Effective disease management and biosecurity measures are crucial in captive wildlife facilities.
