Insights

Feline histoplasmosis, a fungal infection caused by Histoplasma capsulatum, was diagnosed in a domestic shorthaired cat in Thailand. This case highlights the potential for this rare disease in felines and its presentation in a new geographic region.

Area of Science:

  • Veterinary Mycology
  • Feline Infectious Diseases

Background:

  • Histoplasmosis is a systemic fungal infection caused by Histoplasma capsulatum.
  • Feline histoplasmosis is rare and typically presents with disseminated disease.
  • Cutaneous manifestations can occur but are less common.

Purpose of the Study:

  • To report the first case of feline cutaneous histoplasmosis in Thailand.
  • To describe the clinical and histopathological findings of this rare condition in a cat.
  • To confirm the diagnosis using molecular methods.

Main Methods:

  • Clinical examination and history taking.
  • Skin biopsy and histopathological examination.
  • Polymerase Chain Reaction (PCR) for Histoplasma capsulatum identification.

Main Results:

  • A 2-year-old cat presented with multiple skin lesions including papules, nodules, and a chronic wound.
  • Histopathology revealed yeasts within macrophages in the skin.
  • PCR confirmed the presence of Histoplasma capsulatum DNA.

Conclusions:

  • This is the first documented case of feline cutaneous histoplasmosis in Thailand.
  • The findings suggest that Histoplasma capsulatum should be considered in the differential diagnosis of feline skin lesions, even in previously unreported regions.
  • Early diagnosis and treatment are crucial for managing feline histoplasmosis.

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.
Hepatitis01:25

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
Toxoplasmosis01:28

Toxoplasmosis

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...

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...
