“Background Mastitis is a common condition during lactation and its incidence oscillates between 5 and 33% of the lactating mothers [1,2]. The number of non-infectious mastitis that become an infectious disease is usually so high that some authors define the term “”mastitis”" as an infectious process of the mammary gland characterized by a variety of local and systemic symptoms [3]. However, the number of studies dealing with the microbiological aspects of human mastitis is low and the role of specific agents has yet to be described. In fact, published articles on the bacteria causing this condition are scarce and most are, at least, 10 years old [2]. Traditionally,Staphylococcus aureushas been considered the most common etiological agent although, unfortunately, the cases in which microbiological analyses are performed are exceptional. However, treatments with antibiotic or antifungal drugs are usually prescribed without knowing the etiology or the antibiotic susceptibility of the microorganism involved.
