Issues and current standards of controls in microbiome research

Area of Science:

• Microbiology
• Scientific Research Methods

Background:

• The scientific reproducibility crisis necessitates greater attention to good scientific practice.
• Historically, microbiome studies often lacked proper controls, complicating interpretation.
• Implementing and interpreting controls in microbiome research presents significant challenges due to field complexity.

Purpose of the Study:

• To discuss the critical issues surrounding controls in microbiome research.
• To provide a comprehensive overview of problematic points in microbiome study controls.
• To examine the current standards for controls in microbiome research.

Main Methods:

• Literature review and analysis of current practices in microbiome research.
• Discussion of common control issues in sequencing-based microbiome studies.
• Examination of the complexities in interpreting control data.

Main Results:

• Many microbiome studies have historically omitted essential controls.
• There is a growing awareness of the need for controls, but implementation remains complex.
• Interpreting control data in microbiome studies poses significant challenges.

Conclusions:

• Addressing control implementation and interpretation is vital for improving microbiome research reproducibility.
• Clearer standards and methodologies for controls are needed.
• Further research is required to establish best practices for microbiome study controls.
