Molecular and epidemiological analysis of methicillin-resistant Staphylococcus aureus otorrhoea: hospital- or community-acquired?

Abstract

In our cohort, hospital-acquired methicillin-resistant Staphylococcus aureus type 15 was the commonest cause of methicillin-resistant Staphylococcus aureus otorrhoea, despite the fact that these patients all first presented in the community. We believe that contact with hospital staff or health care workers is a risk factor for acquiring methicillin-resistant Staphylococcus aureus otorrhoea in the community.

“…Underlying the concept of external validity has been a significant increase in knowledge of many of pertinent characteristics both of the patients and of the disease (in the past 10 years, PubMed lists 7475 articles for ''otitis,'' http:// www.ncbi.nlm.nih.gov/pubmed, May 9, 2011, 3:27 PM). Examples of this are the advances in genetics concerning otitis [11][12][13][14][15][16][17][18][19] ; a new understanding of susceptibility factors for otitis, 20 of environmental cofactors, [21][22][23][24][25] and of socioeconomic cofactors [26][27][28][29][30][31][32] ; a deepened understanding of the characteristics of the pathogen [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47] ; and others. There is now information as to who is most likely to acquire otitis, how it may affect that individual, and the parameters of the disease agent, as in, for example, the amount and duration of hearing loss, and the potential interactive effects of these on the child.…”
