  • COMMENTS:
    • S. canis has been known to be a pathogen of cats for the last two decades. 70-100 percent of cats in shelter situations may carry the opportunistic bacterium as a commensal in the upper respiratory tract or the vagina. It is rarely seen in single-cat households, especially in older cats. It is a common cause of neonatal septicemia following contaminatin of umbilical vesesels, and may also result in life threatening illness following viral infections or wound contamination in cats of any age. It may also be isolated from cases of chronic sinusitis or cervical lymphadenitis.
