Peritoneal dialysis-associated peritonitis of zoonotic origin, when minor gets major

A 62-year-old patient with peritoneal dialysis (PD)-associated peritonitis is described. Identical strains of Pasteurella multocida and Streptococcus minor were cultured from the dialysate, and from the saliva of her recently adopted stray cat. Pasteurella is not often encountered as pathogen in PD-associated peritonitis, Streptococcus minor has never been cultured in human infection before. We emphasise the importance of hygiene in peritoneal dialysis and the need for testing pets when zoonotic pathogens are cultured.
