Abstract:
Acanthamoeba spp. are pathogenic protozoa that are uncommonly encountered. They tend to infect immunocompromised patients, most often causing cutaneous lesions and in some instances granulomatous amebic encephalitis, as well as rare instances of dissemination to other organs. We present a case of amebic osteomyelitis of the fibula in a patient with rejection of a transplanted kidney who was chronically immune-suppressed.
Insights
Acanthamoeba protozoa can cause rare bone infections in immunocompromised individuals. This case highlights amebic osteomyelitis in a kidney transplant recipient with chronic immunosuppression.
Area of Science:
- Medical Microbiology
- Infectious Diseases
- Immunology
Background:
- Acanthamoeba species are opportunistic protozoan pathogens.
- Infections typically occur in immunocompromised hosts, manifesting as skin lesions or granulomatous amebic encephalitis.
- Disseminated Acanthamoeba infections are rare.
Observation:
- A case of amebic osteomyelitis affecting the fibula is presented.
- The patient had a history of kidney transplant rejection.
- The patient was undergoing chronic immunosuppressive therapy.
Findings:
- The study details a rare presentation of Acanthamoeba infection as osteomyelitis.
- This highlights the potential for disseminated disease beyond typical cutaneous or neurological manifestations.
- The case underscores the risk in chronically immunosuppressed populations.
Implications:
- This case expands the spectrum of known Acanthamoeba infections.
- It emphasizes the importance of considering unusual pathogens in immunocompromised patients with bone lesions.
- Further research may be needed to understand Acanthamoeba's tropism for bone in specific host conditions.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
