“…Sodium hypochlorite 3% in this study failed to eradicate the microbe completely (89% reduction) even after 60 min contact time in the presence of organic matter. This finding agreed with Mete (2019) and contradicted the findings of Bhosale (2017) who reported 7.22 and 8.11 log reductions in P . aeruginosa count after exposure to 5% Sodium hypochlorite for 5 and 30 min, respectively.…”

Aims: This work aimed to determine the occurrence, virulence, antibiogram, carbapenem resistance genes and susceptibility to disinfectants of Pseudomonas aeruginosa isolated from animals, environment and workers in intensive farms. Methods and Results: A total of 610 samples from intensive beef cattle and sheep farms in Kafr El Sheikh Governorate, Egypt were screened for the presence of P. aeruginosa using bacteriological assays. The isolates were characterized by PCR and tested for susceptibility to antibiotics using disk diffusion method and disinfectants by quantitative suspension test. In all, 60 P. aeruginosa isolates were recovered in this study and all isolates harboured at least one of the virulence genes tested. Human P. aeruginosa isolates were highly resistant to cephalosporins, fluroquinolones, aminoglycosides, carbapenems and penicillins+β-lactamase inhibitors than non-human isolates. Colistin resistance was higher in non-human than human P. aeruginosa isolates, whereas low resistance to aztreonam was observed in non-human and human isolates. Carbapenem-resistant P. aeruginosa (CRPA) strains were recovered from workers (56.5%), sheep (8.3%) and cattle (8.3%). All CRPA harboured at least one of the carbapenem resistance genes tested and most of them showed multidrug resistance (MDR) or extensive drug resistance (XDR) phenotypes. Glutaraldehyde 1% and hydrogen peroxide 3% eliminated P. aeruginosa completely in the absence and presence of organic matter within short contact time compared with other disinfectants. Conclusions: This study reported the occurrence of CRPA in animals and workers in intensive farms. Glutaraldehyde and hydrogen peroxide were the most effective disinfectants against P. aeruginosa. Significance and Impact of the Study: The occurrence of CRPA in intensive livestock farms is a serious challenge that threatens animal and human health and increases the risk of P. aeruginosa infection in the community. Therefore, it is vital to control the spread of CRPA by banning or restricting the use of antibiotics and applying proper cleaning and disinfection protocols in livestock farms.
