Detecção de Proteus mirabilis nas fezes de camundongos spf

This study aimed to present the positive results of Proteus mirabilis research from strains inbred mice C57BL/6, BALB/c and BALB/c Nude, originating from the sector of Specific Pathogen Free (SPF) mice - Animal Facilities of Faculdade de Medicina (USP – University of Sao Paulo) and report the importance of isolation of this microorganism in colonies of animals. For this, stool samples from: 71 C57BL/6, 48 BALB/c and 26 BALB /c Nude inbred mice, were inoculated in cultural bacteria specific media and diagnosed in the B Enterokit Probac-Brasil. Our results showed that the strains of C57BL/6, BALB/c and BALB/c Nude presented P.mirabilis in stool, percentages of 80.3%, 62.5% and 73.1% respectively, being unsuitable for use in experimental protocols in the fields of radiobiology, immunology, oncology, and experimental invasive surgeries by interfering mainly on the results of these areas.
