RESUMEN
Many methods have been described for the detection of methicillin-resistant Staphylococcus aureus (MRSA), but the homogeneous or heterogeneous expression of methicillin resistance affects the reliability of those methods. This study demonstrates that close association between methicillin-susceptible S. aureus (MSSA) and MRSA strains in the host colonisation site can present additional problems for the detection of MRSA in clinical laboratories, which may contribute to failure in the control of MRSA infection in hospital. Worse, this association may also account for the emergence of MRSA during antibiotic therapy.

This paper is part of the author's free-teaching theses presented in 1974, in which he has studied 436 persons not carriers of the B.S.A. and other diseases, resident in Campos, Conceição de Macabu and Quissamã (urban and rural zones). Tests were applied in these patients by using standardized antigen of polysaccharide of Paracoccidioides brasiliensis of histoplasmine. The author concluded that there has been existence of the B.S.A.-infection which means what is called "INFEKT". He emphasizes that the epidemiologic researches have important role in the estimation of the incidence of the B.S.A.
