Human commensal bacteria can worsen HIV infection by causing opportunistic infections and increasing viral replication from latent cells. This occurs due to butyric acid from bacteria altering chromatin, potentially accelerating AIDS progression.
Area of Science:
- Microbiology
- Immunology
- Virology
Background:
- Human commensal bacteria are typically non-pathogenic.
- Certain conditions, like HIV infection, alter bacterial behavior.
- These bacteria can cause opportunistic infections and influence viral replication.
Purpose of the Study:
- To review evidence on the role of endogenous microbes in HIV latency.
- To explore the link between these microbes and Acquired Immunodeficiency Syndrome (AIDS) progression.
Main Methods:
- Literature review of recent scientific evidence.
- Analysis of the mechanisms by which commensal bacteria affect HIV.
Main Results:
- Commensal bacteria contribute to opportunistic infections in HIV patients.
- Bacteria, via butyric acid, can disrupt HIV latency by modifying chromatin.
- This disruption augments viral replication, particularly from latently infected cells.
Conclusions:
- Endogenous microbes play a significant role in disrupting HIV latency.
- The interaction between commensal bacteria and HIV may be linked to clinical AIDS progression.

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Defense Mechanism Against Infection
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...
Factors Affecting the Risk of Infection
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 create...
