Insights

Human sporotrichosis, a fungal infection, is increasing, particularly from cats in Brazil. This study highlights an uncommon association between Sporothrix brasiliensis infection and Sweet syndrome, a severe skin reaction.

Area of Science:

  • Mycology
  • Infectious Diseases
  • Dermatology

Background:

  • Human sporotrichosis is an emerging globally distributed fungal infection.
  • Zoonotic transmission via felines has notably increased in Brazil.
  • Sporothrix brasiliensis exhibits higher virulence and atypical presentations.

Purpose of the Study:

  • To report cases of sporotrichosis caused by Sporothrix brasiliensis.
  • To highlight the uncommon association with Sweet syndrome.
  • To alert healthcare professionals in endemic areas.

Main Methods:

  • Case series of 10 patients.
  • Clinical and etiological investigation of sporotrichosis cases.
  • Identification of Sporothrix brasiliensis as the causative agent.

Main Results:

  • All 10 patients were infected with Sporothrix brasiliensis.
  • All patients developed Sweet syndrome, an uncommon hypersensitivity reaction.
  • Sporothrix brasiliensis was linked to feline transmission and severe disease.

Conclusions:

  • Sporothrix brasiliensis infection can lead to Sweet syndrome.
  • This association is critical for diagnosis and management in endemic regions.
  • Increased vigilance for atypical sporotrichosis presentations is necessary.

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...
Toxidromes: Clinical Features01:30

Toxidromes: Clinical Features

Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...
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...
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
American Trypanosomiasis01:22

American 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...
Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
