The genus Proteus includes several species among which Proteus mirabilis is by far the most commonly detected in clinical specimens. In the last twenty years, isolates with multiple acquired resistance genes have been detected, especially in the hospital environment, with a significant impact on the treatment of infections. This research is a ten-year cross-sectional study reporting the detection rates and the antibiotic susceptibility of Proteus spp. in clinical specimens from a healthcare setting in Southern Italy. Of all the 1,600 clinical samples sent to the laboratory, 4.4% were positive to Proteus spp., with P. mirabilis by far the most detected one (83.1%), especially in lower limb ulcers and urines. Moreover, we noted a significant increase of 1200% in the detection rate from 2011 to 2020. Finally, we reported a significant and constantly increasing trend in the detection of antibiotic-resistant strains, ranging from 48.4% in 2011 to 74% in 2020. Our results highlight a clear and significant increase in Proteus spp. detection in a typical hospital setting with a parallel increase in the detection of antibiotic-resistant strains. Therefore, Proteus spp. can be considered one of the main emerging pathogenic bacteria in the hospital environment. |
