Insights

Systemic cat scratch disease (CSD) can affect multiple organs, as seen in a Taiwanese child with liver, spleen, and kidney involvement. Early diagnosis and treatment of this Bartonella henselae infection are crucial for recovery.

Area of Science:

  • Infectious Diseases
  • Pediatrics
  • Microbiology

Background:

  • Systemic cat scratch disease (CSD) is a zoonotic infection typically caused by Bartonella henselae.
  • CSD commonly presents with fever and lymphadenopathy, but visceral involvement can occur.

Observation:

  • A 9-year-old aboriginal girl in Taiwan presented with prolonged fever, abdominal pain, headache, and weight loss.
  • Abdominal CT revealed splenic and renal hypodense lesions; laparotomy showed hepatic and splenic surface lesions.

Findings:

  • Histopathology confirmed necrotizing granulomatous inflammation, suggestive of Bartonella henselae.
  • B. henselae DNA was detected via PCR, and a high antibody titer confirmed visceral CSD.
  • The patient recovered after treatment with rifampin and tetracycline.

Implications:

  • This case highlights the importance of considering systemic CSD in children with fever of unknown origin and abdominal symptoms.
  • Early diagnosis and appropriate antibiotic therapy are essential for managing visceral CSD.
  • Reinforces the need for awareness of Bartonella henselae infections in diverse pediatric populations.

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.
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...
Leishmaniasis01:30

Leishmaniasis

Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...

Rabies

Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
