Cost-effective Method for Microbial Source Tracking Using Specific Human and Animal Viruses
Published on: December 3, 2011
Resumen
Las teorías sobre el origen del SIDA carecen de datos suficientes. Si bien el virus de inmunodeficiencia humana tipo 2 (VIH-2) está relacionado con el SIV en mangabeys de hollín, la evidencia que conecta el predominante virus del SIDA humano (VIH-1) con los SIV de primates sigue siendo escasa.
Área de la Ciencia:
- Virología Virología.
- Epidemiología La epidemiología.
- Salud de los Primates Salud de los Primates
Sus antecedentes:
- Las teorías sobre el origen del Síndrome de Inmunodeficiencia Adquirida (SIDA) se ven obstaculizadas por una significativa falta de datos de apoyo.
- Una década de investigación ha establecido estrechos vínculos genéticos entre el Virus de Inmunodeficiencia Simian (SIV) de mangabeys sooty y el Virus de Inmunodeficiencia Humana tipo 2 (VIH-2).
- El VIH-2 prevalece principalmente en los países de África Occidental.
Objetivo del estudio:
- Investigar los vínculos genéticos entre el Virus de Inmunodeficiencia Humana tipo 1 (VIH-1) y los Virus de Inmunodeficiencia Simio (VIS) encontrados en primates.
- Abordar la escasez de datos que conectan el VIH-1 con sus posibles orígenes SIV.
Principales métodos:
- Análisis genético de cepas SIV de varias especies de primates.
- Secuenciación genómica comparativa para identificar similitudes y diferencias entre SIV y cepas de VIH.
- Análisis filogenético para rastrear vías evolutivas virales.
Principales resultados:
- Si bien existe un vínculo claro entre el SIV de mangabeys de hollín y el VIH-2, los datos que conectan directamente el VIH-1 con los SIV de primates son actualmente limitados.
- El virus del SIDA humano predominante, el VIH-1, muestra escasos vínculos genéticos documentados con SIVs albergados por primates.
Conclusiones:
- La investigación adicional es crucial para dilucidar los orígenes del VIH-1 y su potencial transmisión zoonótica de primates.
- Los datos actuales destacan una brecha significativa en la comprensión de la historia evolutiva del VIH-1 en comparación con el VIH-2.

00:36Viral Mutations
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...
02:33Retroviruses
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
01:20Infection
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

01:18Steps in Outbreak Investigation
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:
01:28Infectious Diseases and Their Occurrence
Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable temporal or...
01:23Investigation of Disease Outbreaks
Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
