“…However, invasive infections caused by A. vaginae, including bacteraemia until today have been reported in only seven patients (8,11,19,24,28,33,58). Although rare, these cases demonstrated the pathogenetic potential of this bacterium, especially after invasive medical-diagnostic procedures (Table 2).…”

“…Samples and methods used for A. vaginae detection are various, depending on the nature of the infection and its presentation. In studies carried out on BV and vaginal microflora, samples usually consist in vaginal swabs or vaginal lavage fluid (15,45), while in bacteraemia and invasive infections there are different specimens, for example blood, swabs or organic material from the infection site (8,11,19,24,28,33,58).…”

“…Upon the last technological and database progresses, the Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) may be a good compromise in precision, processing time and samples preparation, with the only limit in equipment costs. Indeed, its use helps in the diagnosis of almost all the invasive cases of infection caused by A. vaginae (11,24,33,58).…”

“…Lastly, the 16S rRNA gene sequencing could be considered a useful alternative method for a rapid and accurate bacterium detection (8) and applicable upon different matrices, as demonstrated by several cases reported in literature (8,11,19,24,28,33,58). Indeed, PCR assays methods are considered sensitive and specific diagnostic tools, as they can provide additional information on microbial species presence and load in a semi-quantitative and rapid manner (13,15,18,30).…”

Atopobium vaginae: a literature review, on findings and potential clinical implications

et al. 2019

Atopobium vaginaeis an anaerobic Gram-positive bacterium. It is recognized as a causal agent of bacterial vaginosis onset and occasionally associated to gynaecologic-obstetric complications (including pelvic inflammatory disease, endometritis, tubo-ovarian abscesses and preterm delivery with neonatal consequences). Additionally, bacteraemia and invasive infections have rarely been reported. The scientific and technological progress allowed an accurate and rapid identification of Atopobium vaginae supporting diagnosis and clinic interventions. In this article, literature has been deeply examined to report the state-of-the-art on Atopobium vaginae, which might be useful in clinical scenarios.

“…Genetic differences within Atopobium species may explain why single species can be associated with both health and disease. 13 Similar to G. vaginalis, the presence of the organism at a high concentration is highly sensitive and specific for the diagnosis of BV. 14,15 In addition, the presence of G. vaginalis and A. vaginae together is associated with disease recurrence and associated with late miscarriage and prematurity.…”

This study was aimed to determine the Atopobium vaginae associated BV in vaginosis women and women with miscarriage. Also other aim, the DNA sequencing was performed for phylogenetic tree analysis of 16SrRNA gene in local Atopobium vaginae isolates in comparison with NCBI-Genbank global Atopobium vaginae isolates and finally submission of the present isolates in NCBI-Genbank database. One hundred fifty (150) high vaginal swabs were collected from women with vaginosis(Seventy five samples were taken from married vaginosis women without miscarriage and Seventy five samples from vaginosis women with miscarriage) from Babylon city hospital and private clinics. The age of patient (15– 45) years. The sample was collected by disposable swabs, genomic DNA was extracted from these swabs. 16s rRNA gene detection by polymerase chain reaction technique . Atopobium vaginae was isolated on Columbia blood agar supplemented with antibiotic for the first time in Iraq, the study confirmed that 9 (12.00%) and 5(6.66%) of Atopobium vaginae out of 150 swabs isolated from miscarriage and non-miscarriage vaginosis women respectively. According to the detection of the 16S rRNA gene, the study revealed that 69(92.00%)and 47(62.66%)of Atopobium vaginae out of 150 swabs obtained from miscarriage and non-miscarriage vaginosis women respectively. BLAST analysis showed that the 16S rRNA gene shared more than 98- 99% sequence compatibility with the sequences of Atopobium vaginae. Furthermore, the phylogenetic tree analysis of the 16S rRNA gene indicated that local Atopobium vaginae (NO.1 and NO. 2 ) isolates shared higher homology with other Atopobium vaginae isolates available in the GenBank. The homology of the nucleotides was between (99.17% and 98.75%) respectively.

Anaerobic, Gram‐positive, non‐spore‐forming bacilli are widely distributed among the phyla Actinomycetota and Bacillota . The traditional genera Actinomyces , Actinobaculum , Actinotignum , Mobiluncus ,and Varibaculum all belong to the family Actinomycetaceae . The large degree of taxonomic heterogeneity among members of the genus Actinomyces has been recognized for some time. Many Eubacterium species are closely related to clostridia. Actinotignum schaalii is the species most frequently implicated in human disease among the genera Actinotignum and Actinobaculum . The Gram‐variable, curved Gram‐positive rods of the genus Mobiluncus can be detected in samples from the female vaginal tract. The cutaneous group of propionibacteria, now reclassified as Cutibacterium species, are members of the skin microbiota.
