SAAD, Emanuel J et al. Streptococcus agalactiae bacteremia in non-pregnant adult patients at two teaching hospitals. Rev. argent. microbiol. [online]. 2018, vol.50, n.3, pp.280-284. ISSN 0325-7541.  http://dx.doi.org/10.1016/j.ram.2017.08.002.

Streptococcus agalactiae or group B streptococcus (GBS) is a frequent pathogen in immunocompromised adults. The aim of this study was to determine the relative frequency, clinical presentation, antimicrobial susceptibility profile, and risk factors associated with GBS bacteremia in non-pregnant adult patients. We conducted a retrospective analysis of blood cultures performed in two hospitals between the years 2009-2013. From 1110 bacteremia episodes, 13 were caused by GBS, all of which were susceptible to ampicillin. GBS bacteremia was more frequent in females and in patients older than 60 years of age. The most frequent comorbidities were chronic kidney disease, cardiac failure and neoplasia. History of appendectomy was detected in 53.8% of the patients, being the most relevant comorbidity for GBS bacteremia in the multivariate analysis (OR 4.13, p = 0.012). The main presentations were primary bacteremia and soft tissue infection. GBS bacteremia was infrequent in our institution, and a history of appendectomy might be related to bacteremia occurrence.
