Viral Recombination00:57

Viral Recombination

25.5K
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.

Infection01:20

Infection

13.8K
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...

Subviral Agents01:29

Subviral Agents

713
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

6.4K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
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.

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Chemical Agents for Microbial Control01:27

Chemical Agents for Microbial Control

1.4K
Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

  • Review of recent emerging and re-emerging infectious disease events.
  • Analysis of disease characteristics (virulence, mortality, transmission, maternofoetal transmission).
  • Examination of public health authority responses and organizational strategies.

Main Results:

  • Significant increase in the occurrence of emerging/re-emerging infectious diseases.
  • Identification of key pathogens (SARS, MERS-CoV, H5N1, Ebola, Zika) as major public health concerns.
  • Recognition of the need for improved health system organization for rapid case identification, isolation, and management.

Conclusions:

  • Emerging infectious diseases represent a substantial and ongoing threat to global public health.
  • Effective management requires proactive policies, strategic planning, and adaptable health system organizations.
  • Immediate isolation and adequate management protocols are crucial for controlling highly communicable and virulent diseases.
