Resumo
BACKGROUND
Proteus mirabilis is an important uropathogen that causes complicated Urinary Tract Infection (UTI) and induces diarrhea in infants.
OBJECTIVE
This study aimed to investigate P. mirabilis infection in newly weaned infant rhesus monkeys (Macaca mulatta) and ferrets (Mustela putorius furo) with diarrhea.
METHODS
Stool samples were collected from 74 rhesus monkeys and 12 ferrets with diarrhea. Proteus mirabilis was isolated from the samples through Polymerase Chain Reaction. The isolated P. mirabilis was subjected to antimicrobial susceptibility tests.
RESULTS
Seven (7/74, 9.5%) and four (4/12, 30%) P. mirabilis strains were detected in the stool samples collected from the monkeys and ferrets, respectively. Sequence analyses showed that the isolated P. mirabilis was closely related to P. mirabilis strain HI4320, which was isolated from the urine of a patient with a long-term indwelling urinary catheter. In addition, the isolates demonstrated multidrug resistance.
CONCLUSIONS
Rhesus monkeys and ferrets are susceptible to P. mirabilis, making them useful as animal models for future studies on the mechanism of P. mirabilis-induced UTI and its corresponding treatment.
