Summary
Coccidioidomycosis cases in Argentina, though historically rare, significantly increased from 2006-2009, particularly in Catamarca Province. This suggests a potential coccidioidomycosis emergency in the region.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Epidemiology
Context:
- Coccidioidomycosis is infrequently diagnosed in Argentina, primarily in arid, precordilleran regions.
- Historical data reveals a low incidence of coccidioidomycosis from 1892 to 1999.
Purpose:
- To conduct a retrospective analysis of coccidioidomycosis cases in Argentina from 1892 to 2009.
- To detail cases diagnosed between 2006 and 2009 and assess recent incidence trends.
Summary:
- A total of 128 coccidioidomycosis cases were documented between 1892 and 2009.
- The last decade (2000-2009) accounted for 49% of all documented cases (63 cases).
- From 2006 to 2009, 34 cases were identified, with a median age of 31, a male/female ratio of 1.3:1, and 12 immunocompromised individuals. All isolates were identified as Coccidioides posadasii, with 30 cases linked to the Catamarca Valley region.
Impact:
- Annual incidence in Catamarca Province rose from <0.5 to 2 per 100,000 inhabitants between 2006 and 2009.
- This surge indicates a potential coccidioidomycosis outbreak or emergency in this specific Argentine region.
- The findings highlight the need for increased surveillance and awareness of coccidioidomycosis in previously low-risk areas.

01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
01:28Pulmonary Tuberculosis II
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

01:28Fungal 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...
01:31Pulmonary 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:
