Viral Recombination00:57

Viral Recombination

23.7K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

12.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Transmission-based Precautions I: Contact, Enteric, and Droplets

3.9K
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Area of Science:

  • Biopharmaceutical Manufacturing
  • Quality Risk Management
  • Viral Contamination Control

Background:

  • Industry interest is growing in open ballroom manufacturing with closed systems.
  • Previous work established quality risk management (QRM) for viral contamination in cell culture.
  • This study applies QRM principles to novel manufacturing modalities.

Purpose of the Study:

  • To conduct a case study assessing viral cross-contamination risks in an open manufacturing facility.
  • To demonstrate leveraging risk management for risk assessment in new manufacturing approaches.
  • To evaluate viral risk between human (HEK-293) and non-human (CHO) host cell systems.

Main Methods:

  • Followed the International Council for Harmonisation (ICH) quality risk management workflow.
  • Included process mapping, risk question definition, risk evaluation, and risk control.
  • Utilized a Failure Mode and Effects Analysis (FMEA) for detailed risk identification and reduction planning.

Main Results:

  • Assessed viral cross-contamination risks in a simultaneous recombinant protein production scenario.
  • Focused on contamination of downstream filtration (Process 2) from an undetected bioreactor virus (Process 1).
  • Identified specific risks and proposed corresponding risk reduction actions via FMEA.

Conclusions:

  • Quality risk management is applicable to assessing viral contamination in open biomanufacturing.
  • The case study provides a practical framework for risk assessment in advanced manufacturing.
  • Methodologies like FMEA are crucial for identifying and mitigating contamination risks.
