The occurrence of antibiotic-resistant bacteria on the clothes of nursery teachers in daycare centres

Abstract

Aims Childcare facilities act as microenvironments that facilitate and promote the selection, spread and transmission of antibiotic‐resistant micro‐organisms in the community. We focused on the study of antimicrobial resistance and genetic predispositions for β‐lactamase production in bacterial isolates from nursery teachers' clothing. Methods and Results Antimicrobial resistance of bacterial strains belonging to Enterobacteriaceae, Enterococcus, Staphylococcus spp., Pseudomonas spp. and Bacillus spp. isolated from 80 samples of nursery teachers' clothing was determined. The selected ESβL genes were found in 30 (44.1%) of 68 strains examined. The CTX‐M type ESβL determinants were detected in 15.4%, 71.5% and 42.5% of the Enterobacteriaceae, Pseudomonas and Bacillus isolates, respectively. The OXA‐type coding genes were detected only in strains of the genera Pseudomonas (57.1%) and Bacillus (48.6%). Thus, most B. cereus strains were sensitive to the recommended antibiotics used to treat infections caused by these bacteria. Methicillin resistance was phenotypically confirmed in 27 (14.6%) of 185 staphylococcal isolates. Four isolates (2.2%) were identified as MRSA. Vancomycin resistance was not observed in any of the staphylococcal and enterococci strains. Conclusions This study has shown that potential pathogens have been isolated from the clothing of nursery teachers, posing a risk of transmission to children. These clothes should be maintained and properly laundered to avoid cross‐contamination and the spread of multidrug‐resistant (MDR) bacteria in childcare centres. Significance and impact of the study This study provides insight into the route of transmission of MDR micro‐organisms through the clothing of nursery teachers, to which greater importance should be given in the future. Proper procedures for the cleaning and use of clothing in daycare centres should be clarified and standardized.

Molecular characterization and prevalence of Bacillus species isolated from Saudi hospitals

“…Bacillus isolates are often susceptible to broad-spectrum antibiotics such as tetracycline, ciprofloxacin, and erythromycin, which are used to treat gastroenteritis caused by these bacteria. 13 Certain Bacillus species, such as B. cereus , are intrinsically resistant to β-lactams, except carbapenems 14 and can acquire resistance to antibiotics that are commonly used for infection therapy, such as ciprofloxacin, cloxacillin, erythromycin, tetracycline and streptomycin. 15…”

“…The high resistance to penicillin and tetracyclines is not in agreement with a previous report, 13 which showed that Bacillus species are usually susceptible to broad-spectrum antibiotics such as tetracycline, ciprofloxacin and erythromycin, which are used in the treatment of gastroenteritis disease caused by these bacteria. However, certain species within the Bacillus genus, such as B. cereus , are intrinsically resistant to β-lactams, excluding carbapenems, 14 and can furthermore acquire resistance to commonly used antibiotics for the treatment of infections, such as ciprofloxacin, cloxacillin, erythromycin, tetracycline and streptomycin. 15 Most B. cereus isolates produce β-lactamases 16 and are resistant to penicillin and cephalosporins.…”

“…Bacillus isolates are often susceptible to broad-spectrum antibiotics such as tetracycline, ciprofloxacin, and erythromycin, and are used to treat gastroenteritis caused by these bacteria [16]. Certain Bacillus species, such as B. cereus, are intrinsically resistant to -lactams, except carbapenems [17] and can acquire resistance to commonly used antibiotics for infection therapy, such as ciprofloxacin, cloxacillin, erythromycin, tetracycline, and streptomycin [18].…”

Ozone–Vacuum-Based Decontamination: Balancing Environmental Responsibility and Textile Waste

“…Textiles routinely harbour bacteria, encompassing Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, and Pseudomonas aeruginosa [1]. These bacterial strains are potential instigators of afflictions ranging from skin infections to urinary tract infections and respiratory diseases.…”
