Summary
Cryptococcus neoformans remains a significant global health threat, particularly in HIV-associated cases. Despite treatment advances, limited diagnostics and emerging antifungal resistance necessitate further research into pathogenicity and novel therapies.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Public Health
Background:
- Emerging fungal pathogens, like Cryptococcus neoformans, represent a growing global health concern.
- The World Health Organization identified C. neoformans as a top-priority fungal pathogen.
- Understanding its burden, clinical aspects, and antifungal resistance is crucial for public health.
Purpose of the Study:
- To review the global burden, clinical manifestations, and management of cryptococcal infections over the past two decades.
- To assess the current status of antifungal resistance in Cryptococcus neoformans.
- To identify research gaps and drive efforts for improved diagnostics, therapies, and interventions.
Main Methods:
- Systematic reviews of global HIV-associated cryptococcal infection burden trends.
- Scoping reviews of C. neoformans case reports published since 2000.
- Review of recent updates on diagnosis, antifungal treatment, and drug resistance of cryptococcal infections.
Main Results:
- A reduction in HIV-associated cryptococcal meningitis burden since 2009, attributed to antiretroviral therapies, though it still causes 19% of AIDS deaths.
- Increased incidence of cryptococcal meningitis in Europe, North America, and Latin America.
- Limited diagnostic and treatment options, coupled with emerging antifungal resistance, worsen the public health impact.
Conclusions:
- C. neoformans poses an increasing threat due to its ability to infect immunocompetent individuals and the rise of resistant strains.
- Further research into pathogenicity mechanisms and antifungal resistance/tolerance is essential.
- Developing novel diagnostics, therapeutics, and drug targets is critical for reducing the disease burden.

63
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...

01:29Bacterial Phylum Chlamydiae
62
The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic...

22.6K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

8.5K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

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,...
