Summary
Cryptococcosis due to Cryptococcus gattii is a significant tropical mycosis. Advances include identifying risk factors and understanding the etiological agent, but diagnosis and treatment remain challenging.
Area of Science:
- Mycology
- Infectious Diseases
- Tropical Medicine
Background:
- Cryptococcosis caused by the Cryptococcus gattii species complex is a serious mycosis.
- It has a worldwide distribution, with particular importance in tropical regions.
- This review focuses on progress in understanding the disease and its etiological agent in these areas.
Purpose of the Study:
- To review advancements in the knowledge of Cryptococcus gattii and cryptococcosis in tropical regions.
- To highlight progress in understanding the etiological agent and its environmental relationship.
- To identify challenges in diagnosis and treatment.
Main Methods:
- Literature review of studies on Cryptococcus gattii and cryptococcosis in tropical regions.
- Analysis of recent findings on clinical and molecular epidemiology.
- Synthesis of information on environmental niches and risk factors.
Main Results:
- Identification of autoantibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF) as a risk factor in immunocompetent patients.
- Discovery of a new Cryptococcus gattii lineage (VGV) in African environmental samples.
- No increase in cryptococcosis cases associated with the COVID-19 pandemic.
Conclusions:
- Progress has been made in identifying risk factors and understanding Cryptococcus gattii and its environmental interactions.
- Significant achievements in diagnosis and treatment of cryptococcosis are still lacking.
- Cryptococcus gattii is increasingly recognized as an opportunistic pathogen.

Fungal Phylum Microsporidia
144
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...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Pulmonary Tuberculosis I
343
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.

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...

Cystic Fibrosis: Pathogenesis
382
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
