Abstract

Insights

Indoor fungal contamination is a growing concern. This study identified 13 mold species in Kerman, Iran, including clinically significant ones like Cladosporium, highlighting risks from damp building surfaces.

Area of Science:

  • Environmental Microbiology
  • Mycology
  • Building Science

Background:

  • Fungal contamination in damp buildings is a global health and structural concern.
  • Indoor molds can negatively impact both building integrity and occupant health.

Purpose of the Study:

  • To identify and characterize indoor mold species present in buildings within Kerman province, Iran.
  • To assess the fungal diversity in damp indoor environments.

Main Methods:

  • Collection of 110 surface samples from randomly selected damp indoor areas in Kerman province.
  • Identification of fungal isolates using macroscopic and microscopic features.
  • Molecular sequence data analysis for accurate species identification.

Main Results:

  • A total of 218 fungal isolates were obtained, with 13 species identified beyond common genera like Alternaria, Aspergillus, and Penicillium.
  • Cladosporium was the most prevalent genus (43%), followed by Ochroconis musae (10.8%) and Engyodontium album (7.4%).
  • Stachybotrys xigazenensis, E. album, and O. musae were reported for the first time in Iran, with the latter two identified on indoor surfaces.

Conclusions:

  • Indoor surfaces in Kerman province exhibit high fungal richness.
  • Several isolated fungal species possess clinical significance.
  • Damp residential surfaces act as potential reservoirs for clinically relevant molds.

Damped Oscillations01:07

Damped Oscillations

In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is termed undamped. However, friction of some sort usually dampens the motion, so it fades away or needs more force to continue. For example, a guitar string stops oscillating a few seconds after being plucked. Similarly, one must continually push a swing to keep a child swinging on a playground.
Although friction and other non-conservative...

Types of Damping01:20

Types of Damping

If the amount of damping in a system is gradually increased, the period and frequency start to become affected because damping opposes, and hence slows, the back and forth motion (the net force is smaller in both directions). If there is a very large amount of damping, the system does not even oscillate; instead, it slowly moves toward equilibrium. In brief, an overdamped system moves slowly towards equilibrium, whereas an underdamped system moves quickly to equilibrium but will oscillate about...

Magnetic Damping01:17

Magnetic Damping

Eddy currents can produce significant drag on motion, called magnetic damping. For instance, when a metallic pendulum bob swings between the poles of a strong magnet, significant drag acts on the bob as it enters and leaves the field, quickly damping the motion.
If, however, the bob is a slotted metal plate, the magnet produces a much smaller effect. When a slotted metal plate enters the field, an emf is induced by the change in flux; however, it is less effective because the slots limit the...

Statistical Significance01:50

Statistical Significance

Once data is collected from both the experimental and the control groups, a statistical analysis is conducted to find out if there are meaningful differences between the two groups. A statistical analysis determines how likely any difference found is due to chance (and thus not meaningful). In psychology, group differences are considered meaningful, or significant, if the odds that these differences occurred by chance alone are 5 percent or less. Stated another way, if we repeated this...

Significance of Center of Mass01:12

Significance of Center of Mass

The center of mass of an object is defined as the mass-weighted average position of all the particles that comprise the object. The significance of the center of mass of an object can be seen by looking at its dynamics. The time derivative of the center of mass gives its velocity, assuming that the object's mass remains constant over time. Furthermore, the total linear momentum of an object can be seen as the linear momentum of a single particle of the object's total mass moving with...

The Significance of Membrane Transport01:44

The Significance of Membrane Transport

The transport of solutes across the cell membrane is essential for metabolic processes, like maintaining cell size and volume, generating the action potential, exchanging nutrients and gases, etc. Membrane transport can be either passive or active. It can be simple diffusion, facilitated, or mediated transport aided by transport proteins such as transporters and channels.
Transporters facilitate either an active or passive movement of solutes. They can allow a single-molecule transport down its...
