Nocardia is an uncommon Gram-positive organism. It typically appears as delicate filamentous Gram-positive branching rods. In the United States it was estimated to be approximately 500 to 1000 new cases per year. The organism causes disease in immunocompromised individuals with pulmonary infection representing the most common site of infection. Nocardia mikamii has been a recently isolated path...

In June 2010, the Centers for Disease Control and Prevention ended the US public health emergency for the H1N1 pandemic with estimates for total cases, hospitalizations, and deaths counted from April 2009 to April 2010. By the end of this period, the human H1N1 virus was estimated to have been responsible for 12,470 deaths in the United States. Most deaths associated with the seasonal flu or H1...

Mycobacterium genavense is recognized as a life-threatening pathogen in severely immunocompromised patients, mostly in those with advanced human immunodeficiency virus infection. We report a case of M. genavense infection in a lung-transplant recipient with late-onset death occurring from disseminated infection. In human immunodeficiency virus-negative patients, there exist only about 10 report...

A 78-year-old Japanese woman with rheumatoid arthritis was admitted to our hospital due to fever. She had been prescribed prednisolone and bucillamine. Computed tomography revealed abscesses on extremities. M. intracellulare was cultured from her calcaneus osteomyelitis, and this result pointed to a disseminated mycobacterial infection. We drained the abscesses and found M. intracellulare. We s...

Disseminated disease due to rapidly growing non tuberculous mycobacteria especially in the immunocompromised host is being increasingly reported. The usual manifestations of disease being skin and soft tissue infection, post operative wound infection and pulmonary disease. We present a case of a disseminated infection due to Mycobacterium chelonae with features of chronic meningitis and knee jo...

Fingolimod is an oral, disease-modifying therapy used to treat multiple sclerosis (MS). However, severe viral infections, including disseminated varicella-zoster virus infection, herpes simplex encephalitis, varicella-zoster virus encephalitis and vasculopathy, or progressive multifocal leukoencephalopathy, have been reported during fingolimod therapy. Hemophagocytic lymphohistiocytosis (HLH), ...

Both disseminated cryptococcal infection and tuberculosis occur in hosts with impaired cell-mediated immunity, but there have been few reports about the concurrent infections in patients without human immunodeficiency virus infection. A 64-year-old man, who had been taking corticosteroids for interstitial pneumonia, was diagnosed with disseminated cryptococcal infection. While the patient was r...

Leishmania siamensis infection was recently reported from Thailand. Clinical presentation of L. siamensis infections is generally related to human immunodeficiency virus infection. Herein, disseminated dermal L. siamensis infection in a systemic steroid therapy patient from Myanmar is described.

infections and disseminated disease involving multiple organs in immunocompromised patients. In such cases the disease can mimic septicemic melioidosis (4,5). In this previously healthy patient, infection probably originated from the facial abscess. The patient was negative for HIV antibody (Serodia), had no history of diabetes mellitus or other compromising illnesses, and had no evidence of im...

Disseminated nocardiosis is a well-described infection occurring in immunosuppressed individuals. Of the several species of Nocardia, Nocardia farcinica is being increasingly recognized as a pathogen capable of causing severe systemic disease. Described here is a case of disseminated nocardiosis with involvement of the brain, eyes, lymph nodes, and lung with biopsy-proven N. farcinica, with a d...
