The level of C-reactive protein on day 5 compared with day 2 was increased in spite of negative urine and cerebrospinal fluid cultures. The blood sampled on day 6 was found to be positive for lactobacilli, and the isolate was pre-identified as <jats:italic>L. rhamnosus<\/jats:italic> or <jats:italic>Lactobacillus casei<\/jats:italic> on day 11. The strain identity was then verified as <jats:italic>L. rhamnosus<\/jats:italic> GG through PCR and 16S rRNA sequencing. Genotyping with the rep-PCR and AFLP methods confirmed the 100% genetic similarity for both the strain isolated from patient blood and the probiotic product. The newborn became touch-sensitive, cried a lot, had worsening laboratory test results, and increased inflammation parameters, but no fever was observed. After a further 9 days of antibiotic therapy, blood cultures became negative, and laboratory tests improved on day 25. The patient was discharged from the hospital after 27 days. IUGR with a possible link to <jats:italic>L. rhamnosus<\/jats:italic> GG bacteraemia might be a new potential risk group, beside patients with organ failure, immunocompromised status and dysfunctional gut barrier mechanisms, for which safe use of probiotics needs careful attention. Universally accepted or improved guidelines for the safer administration of probiotics in risk groups are urgently needed. This report should not discourage the use of probiotics, but should highlight the need for their careful use in IUGR patients.<\/jats:p>","DOI":"10.3920\/bm2013.0074","type":"journal-article","created":{"date-parts":[[2014,7,18]],"date-time":"2014-07-18T01:36:13Z","timestamp":1405647373000},"page":"397-402","source":"Crossref","is-referenced-by-count":38,"title":["Lactobacillus rhamnosus GG suspected infection in a newborn with intrauterine growth restriction"],"prefix":"10.1163","volume":"5","author":[{"given":"I.","family":"Sadowska-Krawczenko","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Paprzycka","sequence":"additional","affiliation":[{"name":"Hospital Diagnostic Microbiology Laboratory, University Hospital No 2, 75 Ujejskiego St., 85-168 Bydgoszcz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Korbal","sequence":"additional","affiliation":[{"name":"Department of Neonatology, University Hospital No 2, 75 Ujejskiego St., 85-168 Bydgoszcz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Wiatrzyk","sequence":"additional","affiliation":[{"name":"Department of Sera and Vaccines Evaluation, National Institute of Public Health -
