Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

409
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.

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

Applications of Molecular Taxonomy

197
Molecular taxonomy has revolutionized the understanding and classification of bacteria, providing precise insights into their diversity, evolutionary relationships, and ecological roles. By utilizing molecular techniques such as DNA sequencing and fingerprinting, researchers have made significant strides in various fields related to bacterial studies.Resolving Taxonomic AmbiguitiesMolecular taxonomy has been instrumental in distinguishing closely related bacterial species initially thought to...

Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

641
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...

Area of Science:

  • Veterinary Microbiology
  • Wildlife Epidemiology
  • Zoonotic Disease Research

Background:

  • Mycobacterium microti has been unexpectedly prevalent in Northern Italian wild boar populations since 2003.
  • The ecological factors sustaining M. microti transmission within these wildlife populations remain poorly understood.

Purpose of the Study:

  • To investigate the role of wild rodents and environmental reservoirs (water, soil) in the maintenance and transmission of M. microti.
  • To clarify the epidemiological links between M. microti in wild boar, rodents, and their shared habitats.

Main Methods:

  • Real-time PCR was used to screen 120 wild animals and environmental samples from wild boar aggregation sites for the Mycobacterium tuberculosis complex (MTBC).
  • Positive samples were further analyzed for M. microti identification and genetic profiling.
  • Environmental samples included water and mud collected from watering holes and other common areas.

Main Results:

  • Six of 120 animals tested positive for M. microti, with one isolate genetically matching strains found in local wild boar.
  • MTBC DNA was detected in 3 of 20 water samples and 1 of 19 mud samples.
  • The vole-associated spacer oligotype SB0118 was identified in one environmental sample.

Conclusions:

  • Wild rodents, specifically Apodemus sylvaticus, Microtus sp., and Apodemus flavicollis, are implicated in the M. microti cycle.
  • Contaminated environments, such as watering holes, and rodent excreta likely contribute to M. microti transmission to wild boar.
