Bacteria with a Potential for Multidrug Resistance in Hospital Material.

The objective of this research was to determine the antimicrobial resistance of bacteria isolated from items related to hygiene and antisepsis, equipment, and instruments used in different hospital wards. Bacterial isolation and identification, phenotypic antimicrobial susceptibility assays, A gene detection, and multiple antimicrobial resistance index analysis were performed. In total, 105 bacteria were isolated from 138 items. Of these, 49.52% bacteria were collected from instruments, 43.80% from equipment, and 6.66% from items related to hygiene and antisepsis. All gram-positive bacteria (88 isolates) were identified as coagulase-negative . Five species of gram-negative bacilli (17 isolates) were isolated, and the prevalence of (29.41%), (11.76%), and (11.76%) was high. Antimicrobial resistance was reported for 93.33% of the isolates. Gram-positive bacteria were resistant to sulfazotrim (88.64%) and penicillin (82.95%), while gram-negative bacteria showed resistance to sulfazotrim (70.59%) and ampicillin (64.71%). Analysis of multiple antibiotic resistance index showed that 73.33% of the isolates were a high risk to public health. The A gene was detected in 23 (71.88%) isolates. The evaluation of microorganisms isolated in the hospital environment revealed their high multidrug resistance index. Thus our study presses the need to pay more attention to the cleanliness of frequently used instruments, which may be potential sources of infections.
