“…61 The Academy of Breastfeeding Medicine Guideline for management of mastitis recommends that MRSA be considered as a cause of mastitis if there is no improvement after 48 hours on first-line therapy. 62 At that point breast milk cultures need to be collected, specifying the need for sensitivities, and the woman switched to an antibiotic effective against MRSA. 62 This requires knowledge of MRSA-resistance patterns in the community.…”

Staphylococcus aureus is carried by up to one third of the general population; about 2% are carriers for methicillin-resistant S. aureus (MRSA). Infections caused by the antibiotic-resistant form include skin and soft tissue infections, as well as pneumonia, sepsis, and wound infections. Although the risks of hospital-associated systemic infections have decreased with attention to infection control procedures, serious obstetric illness remains a concern. This article describes the range of MRSA infection in the setting of pregnancy and discusses risks to both mother and newborn associated with active MRSA infection during pregnancy and childbirth. Methicillin-resistant S. aureus remains a risk to mothers and newborns, requiring prompt identification and appropriate management.

“…Infectious mastitis is a common condition that affects up to 33% of women during lactation and constitutes one of the main causes of undesired weaning (WHO, 2000; Foxman et al, 2002; Scott et al, 2008; Amir and Academy of Breastfeeding Medicine Protocol Committee, 2014), depriving the mother–infant pair from the health benefits of breastfeeding (U.S. Department of Health and Human Services, 2011).…”

Lactational mastitis constitutes one of the main causes of undesired weaning, depriving the mother–infant pair from the benefits of breastfeeding; therefore, this condition should be considered a relevant public health issue. The role of specific microorganisms remains unclear since human milk cultures and antibiotic susceptibility testing (AST) are not routinely performed, despite the fact that this would be key to ensure an early and effective diagnosis and treatment. The objective of this study was to describe the culturable microbial diversity in 647 milk samples from breastfeeding women with clinical symptoms of mastitis by Matrix-Assisted Laser Desorption Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF) VITEK MS technology and to analyze the antimicrobial susceptibility profiles of a collection of isolates from these samples by the VITEK 2 AST system. Staphylococcus epidermidis was the most common species isolated from mastitis samples (87.6%), while Staphylococcus aureus was detected in 22.1%. Streptococci constituted the second (68.6%) most prevalent bacterial group, with Streptococcus mitis/oralis, Streptococcus salivarius, and Streptococcus parasanguinis detected with frequencies of 40.8, 36.8, and 14.4%, respectively. The antibiotic susceptibility profiles of 642 staphylococcal isolates indicated a remarkable resistance to benzylpenicillin (88.3%) and erythromycin (67.3%) with differences between species. A high percentage of Staphylococcus isolates were resistant to at least one antibiotic (Staphylococcus hominis, 100%; S. epidermidis, 98.2%; S. aureus, 92.9%; Staphylococcus lugdunensis, 90.5%) and the percentage of multidrug-resistance (MDR) isolates was noticeable (S. hominis, 81%; S. epidermidis, 64.4%; S. aureus, 11.5%; S. lugdunensis, 10.5%). In relation to streptococcal isolates (n = 524), AST revealed high or moderate percentages of resistance to erythromycin (68.7%), benzylpenicillin (63.7%), ampicillin (51.5%), and tetracycline (30.8%). Antibiotic resistance to at least one antibiotic was detected in 97.6% of S. parasanguinis, 92.6% of S. salivarius, 83.3% of S. mitis/oralis, and 72.4% of Streptococcus vestibularis isolates. A significant number of MDR streptococcal isolates was also found (S. parasanguinis, 51.2%; S. salivarius, 39.3%; S. mitis/oralis, 34.6%; and S. vestibularis, 19%). The results highlight the important role of coagulase-negative staphylococci and streptococci as human mastitis-causing agents. Moreover, the high rates of antimicrobial resistance among these microorganisms must be contemplated as an issue of clinical relevance in relation to treatment options.

“…The stasis of milk is considered a trigger of lactational mastitis, which is aggravated by the inflammatory process when the protective mechanisms against infection of puerperal women are depleted (1) . Nipple trauma is high in women in early lactation, and constitutes a gateway to etiological agents that cause mastitis (2) . Over 25% of puerperal women are estimated to have had at least one episode of lactational mastitis and 4 -8% have had recurrent episodes of mastitis (3) .…”

Objective: to identify characteristics of women who have suffered severe lactational mastitis. Method: a descriptive, retrospective, documentary, quantitative study was performed. Data were collected from patient records of 114 hospitalized women from January of 2009 to December of 2013. Data were analyzed by using descriptive statistics. Results: a higher percentage of severe lactational mastitis was found in young, primiparous women who had completed high school, who had no partner, and did not have a job; 96.5% of women had breast complications before admission and remained hospitalized an average of 4.4 days; at discharge, 23.7% of women had weaned their infants. Conclusion: this study showed that severe lactational mastitis can cause great harm to the woman and the baby. Key words: Mastitis; Health Profi le; Breast Feeding. RESUMO Objetivo: identifi car as características de mulheres que sofreram mastite lactacional grave. Método: estudo descritivo, retrospectivo e documental, com abordagem quantitativa. Os dados foram coletados de registros da assistência nos prontuários de 114 mulheres internadas no período de janeiro de 2009 a dezembro de 2013. Análise mediante estatística descritiva. Resultados: constatou-se maior porcentagem de mastite lactacional grave em mulheres jovens, primíparas, com ensino médio completo, que não tinham companheiro e não trabalhavam fora do lar; 96,5% das mulheres tiveram alguma intercorrência mamária antes da internação e permaneceram internadas em média 4,4 dias; na alta hospitalar 23,7% das mulheres desmamaram. Conclusão: este estudo mostrou que a mastite lactacional grave pode causar grandes danos à mulher e ao bebê. Descritores: Mastite; Perfi l de Saúde; Aleitamento Materno. RESUMEN Objetivo: identifi car las características de las mujeres que sufrieron mastitis severa de la lactancia. Método: se realizó investigación descriptiva, retrospectiva y documental con enfoque cuantitativo. Datos eran recogidos procedentes de los registros de hospitalización de las 114 mujeres ingressadas de enero de 2009 a diciembre de 2013. El análisis mediante estadística descriptiva Resultados: encontrado una mayor proporción de mastitis de la lactancia severa en mujeres jóvenes, primíparas, que habían completado la escuela secundaria, que no tenían pareja, y que no trabajan fuera de casa, el 96,5% de las mujeres tenía alguna complicación de mama antes de su ingreso al hospital y permanecieron hospitalizados un promedio de 4,4 días, al momento del alta 23,7% de las mujeres renunció a la lactancia materna.
