Infection

7.0K
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...

Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

209
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Transmission-based Precautions II: Airborne and Protective Environment

1.2K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Pulmonary Tuberculosis I

216
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

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

3.3K
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...

Pulmonary Tuberculosis V01:28

Pulmonary Tuberculosis V

165
Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Area of Science:

  • Microbiology
  • Pathogen Biology
  • Toxicology

Background:

  • Bacillus anthracis forms highly resistant spores, enabling long-term survival and transmission via soil or animal products.
  • Anthrax infection occurs through cutaneous, inhalation, or gastrointestinal routes, leading to severe disease.
  • Anthrax toxin is a critical virulence factor responsible for host cell death.

Purpose of the Study:

  • To review the sporulation, transmission, and pathogenesis of Bacillus anthracis.
  • To summarize current prevention and treatment strategies for anthrax.
  • To explore the potential of anthrax toxin as a cancer therapeutic.

Main Methods:

  • Literature review of scientific publications on Bacillus anthracis.
  • Analysis of existing data on anthrax pathogenesis and virulence factors.
  • Examination of current vaccine efficacy and therapeutic applications.

Main Results:

  • Bacillus anthracis pathogenesis involves spore formation, transmission, and toxin-mediated host cell damage.
  • Protein kinases and phosphatases play a role in B. anthracis toxin production and virulence.
  • FDA-approved vaccines (BioThrax, CYFENDUS) exist for anthrax prevention.

Conclusions:

  • Understanding B. anthracis sporulation and pathogenesis is crucial for disease control.
  • Anthrax toxin shows promise as a novel therapeutic agent for cancer treatment.
  • Continued research is needed to enhance anthrax prevention and treatment strategies.
