Neonatal mastitis due to escherichia coli

Focal Bacterial Infections

“…Abscesses of the skin and subcutaneous tissue are usually caused by S. aureus and, less frequently, by group A streptococci, GBS [607,608], or gram-negative enteric bacilli [609][610][611][612][613][614][615][616][617]. Community-acquired MRSA organisms are even more likely to produce skin infections with abscess formation.…”

“…S. aureus is the most frequent etiologic agent in breast abscess, but gram-negative enteric bacilli may be becoming more common [611,615,616]. Of 36 cases with mastitis seen in Dallas, Texas, during a 16-year period, 32 cases were caused by S. aureus, 1 was caused by E. coli, and 2 were caused by Salmonella species; both E. coli and S. aureus were isolated from one abscess [632].…”

Abszedierende Mastitis bei einem 4 Wochen alten Kind

“…jungen Säuglingen kommt in entwickelten Ländern sehr selten vor [9,10,12]. Wenn es zu einer solchen Erkrankung kommt, handelt es sich ausschlieûlich um ehemalige reife Neugeborene, meist in den ersten 5 Lebenswochen [2, 8 ± 10, 14].…”

“…In 80±90 % der Fälle sind es S. aureus-Infektionen [1 ± 3, 5, 8, 10], aber auch Streptokokken [2,4,14], E. coli [2,12,13] ± Ein bakteriologischer Erregernachweis sollte immer angestrebt werden. ± Bei Abszedierung ist eine chirurgische Inzision notwendig.…”

Mastitis in early infancy

“…On occasion, it is associated with infection, either mastitis or abscess. The causative agent is often Staphylococcus aureus [1][2][3][4][5][6], though cases due to Gram-negative enteric bacteria have also been reported [4,[6][7][8][9][10][11]. The aim of this retrospective case series study was to evaluate the clinical features of young infants with mastitis, to compare the findings in bacterial cultures with previous, older reports and to comment on the appropriate clinical management.…”
