Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...

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...
Bacterial Meningitis I: Introduction01:22

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
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...
Antifungal Agents01:15

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Area of Science:

  • Mycology
  • Dermatology
  • Infectious Diseases

Background:

  • Tinea capitis (TC) is a prevalent fungal infection impacting the scalp, eyebrows, and eyelashes.
  • Dermatophyte infections represent a significant public health concern globally.

Purpose of the Study:

  • To identify the primary fungal agent responsible for Tinea capitis in Botswana.
  • To investigate the correlation between specific fungal species and clinical presentations of Tinea capitis.

Main Methods:

  • Fungal cultures and potassium hydroxide (KOH) mounts were performed on clinical samples.
  • Dermasel and Sabouraud dextrose agar were utilized for fungal isolation and growth.
  • Lactophenol cotton blue staining facilitated the morphological identification of fungal isolates.

Main Results:

  • Trichophyton violaceum was identified as the predominant dermatophyte causing Tinea capitis.
  • Trichophyton tonsurans was isolated in a single case.
  • Both identified species are anthropophilic, indicating human-to-human transmission.

Conclusions:

  • Tinea capitis predominantly affects individuals aged 1-15 years, with 81% of cases falling within this demographic.
  • Trichophyton violaceum is the most frequently isolated dermatophyte species in the studied population.
  • The findings highlight the etiological agents of Tinea capitis in Botswana, informing potential treatment and prevention strategies.
