Pseudomonas species isolated from camel meat: quorum sensing-dependent virulence, biofilm formation and antibiotic resistance

Abstract

Aim: This research pioneers the process of obtaining information concerning the distribution and existence of seven ESBL genes linked to Pseudomonas, three virulence and five quorum sensing separated from 100 camel meat samples using PCR. Materials & methods: The Vitek system was used to identify Pseudomonas species. Phenotypic antibiotic resistance of 16 antibiotics was tested by disc diffusion. Quantification of pyocyanin, elastase, alkaline protease, biofilm and Vero cell cytotoxicity was also implemented. Results: The total number of Pseudomonas species isolated from camel meat was 10/100 identified as Pseudomonas aeruginosa 8/10, Pseudomonas fluorescens 2/10. The isolates were multidrug resistant and were resistant to four to eight antibiotics representing four to six classes. The 15 genes exhibited a huge diversity in their association. Conclusion: The results indicated that camel meat is an unpropitious hotbed for Pseudomonas species of clinical significance.
