Sneathia amnii and Maternal Chorioamnionitis and Stillbirth, Mozambique.

We report a case of Sneathia amnii as the causative agent of maternal chorioamnionitis and congenital pneumonia resulting in a late fetal death in Mozambique, with strong supportive postmortem molecular and histopathologic confirmation. This rare, fastidious gram-negative coccobacillus has been reported to infrequently cause abortions, stillbirths, and neonatal infections.

Bloodstream infections among children with juvenile idiopathic arthritis: a prospective study from the onset of disease.

OBJECTIVES: To describe the incidence and nature of bloodstream infections (BSI) among children with juvenile idiopathic arthritis (JIA) followed-up prospectively from disease onset. METHODS: The Social Insurance Institution's (SII) national register on individuals with reimbursement for medication of chronic diseases was used to identify children with JIA from 2004 through 2011 and their medications. The National Infectious Disease Register (NIDR) collects data of all blood culture positive samples from all microbiology laboratories in Finland. We combined the NIDR and SII registers to identify JIA patients with BSI. Clinical and laboratory data of each JIA-BSI patient were collected from hospital records. RESULTS: There were 1604 JIA patients and 6630 person-years of follow-up. Five patients had BSI. During the first 5 years after diagnosis the cumulative emergence of BSI was 0.38% [95% confidence interval (CI) 0.16% to 0.92%]. The incidence rates were 7.5/10 000 follow-up years for JIA (95% CI 2.4-17.6) and 2.8/10 000 follow-up years for the age-matched general population (95% CI 2.7-2.9). The standardised incidence ratio was 3.0 (95% CI 1.2 to 7.2). The causative bacteria were Streptococcus pneumoniae, Staphylococcus aureus, Escherichia coli and Fusobacterium necrophorum. Three patients were on anti-rheumatic drugs, including two on TNF inhibitors. All patients responded rapidly to antimicrobial therapy and recovered uneventfully. CONCLUSIONS: Although BSI is rare among children with JIA, the incidence is 3-fold higher than among the general population.

INTRODUCTION: Leptotrichia bacteria belong to the group of Gram-negative anaerobes most frequently colonizing the oral cavity and reproductive organs. Leptotrichia sanquigenes constitute one of the bacterial factors in postpartum bacteremia of mothers and newborns, whilst Leptotrichia amnionii sp. nov., described for the first time in 2002, has turned out to be the etiopathogenetic factor in missed abortion in the second trimester of pregnancy. AIM: The purpose of this study was evaluation of the frequency of occurrence of Leptotrichia amnionii sp. nov. in patients in the 1st, 2nd and 3rd trimester of pregnancy. MATERIALS AND METHODS: The study involved 69 patients. Amplification reactions detecting the presence of Leptotrichia amnionii so. RNA in the smears were performed using specific starters complementary to 16SrRNA Leptotrichia amnionii--primer 1 Lam upper and primer 2 Lsp lower--complementary to Leptotrichia 16SrRNA. After amplification, the specimens were placed on 1% agarose gel in the presence of MassRuler marker (Fermentas). Next, PCR products were ligated to pGEM-T Easy Victor and then competent E. coli DH5 alpha cells were transformed with pGEM vector with an insert. Plasmid DNA isolation was performed using Plasmid Mini kit from A&A Biotechnology. Sequencing of inserts from the purified plasmids was performer in Molecular Biology Techniques Laboratory in the Department of Biology at Adam Mickiewicz University in Poznan. RESULTS: In the group of 69 pregnant patients Leptotrichia amnionii sp. nov. was identified in 8 women, which is 11.6%. CONCLUSION: Recently identified Leptorichia amnionii sp. nov. is a bacterie, which relatively frequently occurs in pregnant women.
