Insights

This study found Trichophyton species, particularly T. mentagrophyte, are the most common cause of fungal skin infections in Himachal Pradesh, India. The research highlights the prevalence of dermatophyte infections in adults aged 21-50.

Area of Science:

  • Medical Mycology
  • Epidemiology
  • Dermatology

Background:

  • Superficial fungal infections caused by dermatophytes are prevalent globally, especially in tropical and subtropical regions.
  • Dermatophytes include common genera such as Trichophyton, Microsporum, and Epidermophyton.

Purpose of the Study:

  • To investigate the epidemiological patterns of dermatophyte species causing superficial mycoses in Himachal Pradesh, India.
  • To analyze the prevalence of different dermatophyte species in relation to clinical conditions, age, and sex.

Main Methods:

  • Collection of 202 samples (skin scrapings, nail scrapings, hair follicles) from patients with various tinea infections.
  • Culturing of samples to identify dermatophyte species.
  • Analysis of epidemiological data including age, sex, and clinical presentation.

Main Results:

  • 74 out of 202 samples (36.6%) tested positive for dermatophyte species.
  • Trichophyton spp. were predominant (98.65%), with T. mentagrophyte (63.5%) and T. rubrum (35.1%) being the most common.
  • Microsporum gypseum was identified in 1.35% of cases; Epidermophyton spp. were not found.
  • The male to female ratio was 63:11, and the most affected age group was 21-50 years (64.9%).

Conclusions:

  • Trichophyton species, particularly T. mentagrophyte, are the primary agents of superficial fungal infections in Himachal Pradesh.
  • The study provides crucial epidemiological data on dermatophytosis in this region, with a higher incidence in adult males.

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

The Skin Microbiota01:27

The Skin Microbiota

The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...
