Rhodococcus equi is an unusual cause of infection in humans. Infection in immunocompetent patients is extremely rare-only 19 cases in immunocompetent hosts have been reported. Localized infections represent nearly 50% of reported cases. Pulmonary infections account for only 42% of infections in immunocompetent hosts, compared with 84% of infections in immunocompromised hosts. The mortality rate...

introduction: invasive fungal sinusitis, though considered to be rare entity, is nowadays frequently encountered, not only in immunocompromised patients but also in immunocompetent patients. the changing prevalence towards immunocompetent hosts is due to the indiscriminate usage of broad spectrum antibiotics, steroids, and immunosuppressive drugs. diagnosing invasive fungal sinusitis should not...

Listeria monocytogenes (L. monocytogenes) is an uncommon cause of bacterial meningitis in immunocompetent adults. Patients with immunosuppression are at increased risk of developing serious invasive diseases, particularly meningitis. We describe a case of meningitis caused by L. monocytogenes in an immunocompetent and previously healthy 34-year-old adult. The patient received treatment with int...

Disseminated histoplasmosis affecting the adrenal gland(s) of immunocompetent adults is a very rare infection. Here, we present a case of bilateral adrenal histoplasmosis in an immunocompetent, 62-year-old gentleman from Texas along with a brief review of the published literature. Given the risk of patient decompensation secondary to adrenal insufficiency and the wide availability of effective ...

Cytomegalovirus colitis is uncommon in immunocompetent hosts. Thus, a case of bloody diarrhoea and weight loss in an immunocompetent elderly man is reported. Cytomegalovirus colitis was diagnosed by identifying inclusion bodies with positive immunohistochemistry for cytomegalovirus in the histological specimens obtained by colonoscopy. The patient responded to gancyclovir treatment. We conclude...

We report a case of severe toxoplasmosis in an immunocompetent patient, characterized by pneumonia, retinochoroiditis, hepatitis and myositis. Diagnosis was confirmed by serology, T. gondii in thick blood smear and presence of bradyzoites in muscle biopsy. Treatment with pyrimethamine plus sulfadoxine was successful but visual acuity and hip extension were partially recovered. This is the first...

The dematiaceous fungus Cladosporium cladosporioides (C. cladosporioides) is a widely distributed saprophyte that occasionally infects the lung, skin, eye and brain in both immunocompetent or immunosuppressed hosts. We report a rare case of an immunocompetent 56-year-old male patient who presents with a six-year history of onychomycosis caused by C. cladosporioides following trauma. The patient...

pulmonary aspergillosis is a well known entity occurring in immunocompetent persons. cutaneous aspergillosis, on the other hand, has been described in cases of suppressed immunity. recently, invasive aspergillosis has been reported in patients with subtle immune dysfunction such as those with critical illness and advanced cirrhosis. we report a case of scrotal aspergillosis in association with ...

Invasive aspergillosis has emerged as a major cause of life-threatening infections in immunocompromised patients. Recently, patients with chronic obstructive pulmonary disease, who have been receiving corticosteroids for a long period, and immunocompetent patients in the intensive care unit have been identified as nontraditional hosts at risk for invasive aspergillosis. Here, we report a case o...

Zygomycosis is an opportunistic fungal infection with a high mortality rate. It is known to cause invasive disease in immunocompromised hosts but it may produce only cutaneous/ subcutaneous infections in immunocompetent hosts. Treatment is difficult due to its fulminant course and lack of effective anti-fungal drugs. Here, we report a rare case of subcutaneous zygomycosis caused by Mucor hiemal...
