Objective:

To describe the profile of multidrug-resistance (MDR), extensively resistance (XDR) and pandrug-resistance (PDR) to antibacterial drugs in isolates from patient samples from a third level private hospital in the North of Mexico.

Method:

A retrospective study was carried out during the period from February 2016 to April 2019. From 156 clinical samples of urine, wounds, blood, expectoration and other fluids, 166 bacteria were isolated; 10 samples included two microorganisms. Isolated microorganisms were classified into MDR, XDR or PDR.

Results:

78% of the Gram negative and 69% of the Gram positive isolates showed MDR, XDR or PDR. Staphylococcus epidermidis was the most frequently isolated MDR Gram positive bacteria. Escherichia coli and Klebsiella sp. were among the most frequent MDR Gram negative. In two cases, the clinical isolates of Pseudomonas aeruginosa from the neonatal intensive care unit showed PDR.

Conclusions:

The intensive care, surgery and neonatal intensive care unit services deserve special attention due to the high proportion of MDR isolates and the presence of PDR due to P. aeruginosa.
