ABSTRACT: Our study was carried out to determine the phenotypic characterization antimicrobial susceptibility of Proteus mirabilis from fish in FCT, Abuja using isolation, selective plating, preliminary observation, complete biochemical method and antimicrobial susceptibility testing. The biochemical tests conducted includes include Citrate Utilization test, Triple Sugar Iron test, Urea test, Methyl Red test, Indole test, and Voges Proskauer test. The isolates were confirmed by MicrobactTMGNB24E identification kit (Oxiod, UK). A total of 400 fish samples were bought in the market from three area council of the FCT. The result of the study showed overall prevalence rate of (13) 3.25% of Proteus mirabilis isolates. Distribution based on Area councils showed that AMAC had higher prevalence rate of 4.81%, while Bwari had 2.99% and Gwagwalada with 2.57% prevalence. All isolates were subjected to antimicrobial susceptibility testing using the modified single disc diffusion method. From the antimicrobial susceptibility testing done it was discovered that Proteus mirabilis are resistant to Amoxyclav (100%), Erythromycin (92.3%), Tetracycline (92.3%) and Ceftriaxone (23.1%). However, the isolates were susceptible to Ofloxacin (100%), Netillin (92.3%), Levofloxacin (92.3%), Ceftazidime (76.9%), Co-trimoxazole (69.2%) and Gentamicin (61.5%). Since Proteus mirabilis sources of zoonotic diseases and can potentially be dangerous to humans and other animals, our research was able to isolate it from fresh water fish sold in the Federal Capital Territory. This makes public health awareness of the risks associated with Proteus mirabilis in Nigeria necessary.
