DPE = direct pathological examination; DMEI = direct microscopic examination of imprints; 1 legend in bacteriological processing section, in all cases corresponding to Gram positif cocci; 2 Streptococcus sp was identified as belonging to streptococci viridans group; 3 the number before the species means the number of positive blood cultures; the ATB = antibiotic; Neg = negative; ND = not done; retrospective study impossible for patients 3, 9, 10, 16.
