Microbiome Compositions From Infertile Couples Seeking Fertilization, Using 16S rRNA Gene Sequencing Methods: Any Correlation to Clinical Outcomes?

Background: Bacterial infections are usually suspected in infertile couples seeking IVF with no clear understanding of the microbial compositions present in the seminal fluids and vaginal niche of the patients. We used next-generation sequencing technology to correlate microbiota compositions with IVF clinical outcomes.

Methods: Thirty-six couples were recruited to provide seminal fluids and vaginal swabs.

Topical cream containing live lactobacilli decreases malodor-producing bacteria and downregulates genes encoding PLP-dependent enzymes on the axillary skin microbiome of healthy adult Nigerians.

Background: Clinical data exist that support the utility of topical probiotics for certain dermatological diseases such as atopic dermatitis, acne, and psoriasis. However, there is paucity of data on the use of live lactobacilli to control axillary malodor. The objective of this study was to determine whether application of topical oil-based cream containing live Lactobacilli could decrease malodor-producing bacteria in the axilla of healthy subjects.

A comparative study of the oral microbiome compositions of healthy postmenopausal, premenopausal, and prepubertal Nigerian females, using 16s rrna metagenomics methods.

Introduction: There is a paucity of information on the oral microbiome compositions of Nigerians, mostly due to lack of appropriate molecular techniques. In this pilot study, we sought to determine and characterize the oral bacterial compositions of "healthy" females.

Materials And Methods: Oral samples were collected from three randomly selected females aged 56, 28, and 8 years.

Bioinformatic analysis of dihydrofolate reductase predicted in the genome sequence of Lactobacillus pentosus KCA1.

Physiologic studies of Lactobacillus species show that some species cannot synthesize folate de novo, which is required for growth. Folate plays a critical role in regulating the amount of tetrahydrofolate in the cell that is utilized for DNA replication, and proliferation of the erythropoietic system. We recently sequenced the genome of Lactobacillus pentosus KCA1, isolated from a Nigerian subject.

Genome sequence of Lactobacillus pentosus KCA1: vaginal isolate from a healthy premenopausal woman.

The vaginal microbiota, in particular Lactobacillus species, play an important role in female health through modulation of immunity, countering pathogens and maintaining a pH below 4.7. We report the isolation and genome sequence of Lactobacillus pentosus strain KCA1 (formally known as L.
