Microbial Classification System01:24

Microbial Classification System

Classification is the process of organizing organisms into hierarchically inclusive groups based on their phenotypic similarities or evolutionary relationships. A species comprises one or more strains, and closely related species are grouped into genera. Genera are further classified into families, families into orders, orders into classes, and so forth, up to the domain level, which is the broadest taxonomic rank derived from a combination of phenotypic and genotypic data.The nomenclature of...
Biological Methods for Microbial Control01:28

Biological Methods for Microbial Control

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...
Chemical Agents for Microbial Control01:27

Chemical Agents for Microbial Control

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...
Transmission-based Precautions II: Airborne and Protective Environment01:25

Transmission-based Precautions II: Airborne and Protective Environment

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...
Physical Properties of Amines01:26

Physical Properties of Amines

Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.
Standard Precaution01:26

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Area of Science:

  • Microbiology
  • Environmental Science
  • Museum Studies

Context:

  • Museums house diverse collections, necessitating assessment of indoor environmental quality.
  • Microbiological contamination poses risks to both cultural heritage and human health within museum settings.

Purpose:

  • To quantify the level and types of microbiological contamination in various museum premises.
  • To identify specific fungal species that can serve as indicators of harmful biological agents at museum workstations.

Summary:

  • Microbiological analysis of air and surfaces in 14 museum premises revealed significant contamination, with fungi being the dominant microorganisms.
  • Fungal levels in air and on surfaces frequently exceeded recommended reference values, particularly in the Museum of Archeology and Ethnography and the Museum of Independence Traditions.
  • Ten fungal species, including Aspergillus, Cladosporium, Penicillium, and Rhizopus nigricans, were identified as potential indicators of biological hazards.

Impact:

  • Provides crucial data for implementing targeted strategies to mitigate microbial risks in museums.
  • Establishes a basis for selecting indicator organisms for monitoring biological contamination in museum environments.
  • Contributes to safeguarding both the integrity of museum collections and the health of staff and visitors.
