“…In another study, eradication of persistent MRSA carriage from denture wearers was successful only after heat sterilizing or remaking of the dentures that had become persistently colonized. 128 A recent study by Vanzato et al 126 reported carriage rates of 47.6% and 4.1% for S. aureus and MRSA respectively in the oral cavity of healthcare workers. Also, quite recently, an MRSA carriage study conducted among dental students in Italy reported a carriage rate of 1.9% (n = 3) in the mouth; the total carriage prevalence was 3.2% (n = 5), representing a composite of oral, nasal, and skin carriage.…”

“…Recent reports indicate high S. aureus and MRSA carriage rates in the oral cavity. 126,127 Although it is unclear whether these reported high rates are as a consequence of increased focus on S. aureus and MRSA, it is noted that MRSA carriage in the mouth may constitute a reservoir for subsequent colonization of other anatomical sites or for cross-infection to other people. Evidence from several studies indicate that MRSA appears to preferentially colonize denture surfaces in the mouth.…”

The oral cavity harbors a multitude of commensal flora, which may constitute a repository of antibiotic resistance determinants. In the oral cavity, bacteria form biofilms, and this facilitates the acquisition of antibiotic resistance genes through horizontal gene transfer. Recent reports indicate high methicillin-resistant Staphylococcus aureus (MRSA) carriage rates in the oral cavity. Establishment of MRSA in the mouth could be enhanced by the wide usage of antibiotic prophylaxis among at-risk dental procedure candidates. These changes in MRSA epidemiology have important implications for MRSA preventive strategies, clinical practice, as well as the methodological approaches to carriage studies of the organism.

“…For example, the lowest bacterial concentrations were found on nurses’ hands who have more administrative tasks, whereas the highest was found on SOSU assistants who have more direct contact with residents during care and nursing tasks. Matching these findings, in a study by Gaspard et al (2010) , the authors found that social and healthcare assistants had a higher bacterial concentration on their forearms from personal care tasks with patients than for example nurses and cleaners.…”

Indoor microbial exposure may cause negative health effects. Only little is known about the occupational microbial exposure in nursing homes and the factors that influence the exposure. The exposure in nursing homes may be increased due to close contact with elderly persons who may carry infectious or antimicrobial-resistant microorganisms and due to handling of laundry, such as used clothing and bed linen. We investigated the microbial exposure in 5 nursing homes in Denmark, by use of personal bioaerosol samples from different groups of staff members taken during a typical working day, stationary bioaerosol measurements taken during various work tasks, sedimented dust samples, environmental surface swabs, and swabs from staff members’ hands. From the samples, we explored bacterial and fungal concentrations and species composition, endotoxin levels, and antimicrobial resistance in Aspergillus fumigatus isolates. Microbial concentrations from personal exposure samples differed among professions, and geometric means (GM) were 2,159 cfu/m3 (84 to 1.5 × 105) for bacteria incubated on nutrient agar, 1,745 cfu/m3 (82 to 2.0 × 104) for bacteria cultivated on a Staphylococcus selective agar, and 16 cfu/m3 air for potential pathogenic fungi incubated at 37 °C (below detection limit to 257). Bacterial exposures were elevated during bed making. On surfaces, the highest bacterial concentrations were found on bed railings. The majority of bacterial species found were related to the human skin microflora, such as different Staphylococcus and Corynebacterium species. Endotoxin levels ranged from 0.02 to 59.0 EU/m3, with a GM of 1.5 EU/m3. Of 40 tested A. fumigatus isolates, we found one multiresistant isolate, which was resistant towards both itraconazole and voriconazole, and one isolate resistant towards amphotericin B. In conclusion, we give an overview of the general microbial exposure in nursing homes and show that microbial exposures are higher for staff with more care and nursing tasks compared with administrative staff.
