The vaginal microbiota of pregnant women varies with gestational age, maternal age, and parity

This study characterizes the vaginal microbiota in pregnant African-American women across gestation, identifying key factors like gestational age and parity that influence its composition.

Homeostatic macrophages prevent preterm birth and improve neonatal outcomes by mitigating in utero sterile inflammation

The paper shows that M2 macrophages prevent preterm birth and improve neonatal outcomes by reducing in utero sterile inflammation in mice.

Taxonomic, genomic, and functional variation in the gut microbiomes of wild spotted hyenas across two decades of study

This study analyzes gut microbiome variation in wild spotted hyenas over 23 years, finding individualized and age-related microbiomes with novel genomic diversity.

Is there a placental microbiota? A critical review and re-analysis of published placental microbiota datasets

This paper re-analyzes 15 placental microbiota datasets to determine if a placental microbiota exists, finding that bacterial signals likely arise from contamination rather than a true microbiota.

Bacterial profiles of the human placenta from term and preterm deliveries

This study investigates bacterial profiles in term and preterm placentas, finding no placental microbiota in term pregnancies but variable bacterial presence in preterm cases, influenced by delivery mode.

Microbiota of the pregnant mouse: characterization of the bacterial communities in the oral cavity, lung, intestine, and vagina through culture and DNA sequencing

This study characterizes the microbiota of pregnant mice at four body sites using culture and DNA sequencing, finding that vaginal microbiota can be cultured and show similarities to human vaginal microbiota.

LACK OF EVIDENCE FOR A VIABLE MICROBIOTA IN MURINE AMNIOTIC FLUID

This study investigates whether murine amniotic fluid contains a viable microbiota, finding no evidence of a viable microbial community despite detecting bacterial DNA.

Host phylogeny and host ecology structure the mammalian gut microbiota at different taxonomic scales

This study examines how host phylogeny and diet shape gut microbiota in 11 herbivore species, finding host taxonomy explains more variation than diet or season.

Lack of evidence for microbiota in the placental and fetal tissues of rhesus macaques

This study investigates the presence of viable bacterial communities in fetal and placental tissues of rhesus macaques using culture, qPCR, and DNA sequencing, finding no consistent evidence of microbial colonization.

No consistent evidence for microbiota in murine placental and fetal tissues

This study investigates the presence of bacterial communities in placental and fetal tissues of mice using culture, qPCR, and 16S rRNA sequencing, finding no consistent evidence of microbiota.

Microbial community structure and microbial networks correspond to nutrient gradients within coastal wetlands of the Laurentian Great Lakes

This study examines microbial community structure and networks in coastal wetlands of the Laurentian Great Lakes, finding differences linked to nutrient gradients and human activity.
