What is Nocardia Cyriacigeorgica?
Nocardia cyriacigeorgica is an aerobic, gram-positive, partially acid-fast, partially branched bacteria that primarily resides in soil, characterized by dry white colonies (6).
What is pulmonary Nocardia?
Nocardiosis is an infectious pulmonary disease characterized by abscesses in the lungs. These abscesses may extend through the chest wall. The infection is spread through the body via the bloodstream by a microorganism called Nocardia asteroides.
What causes pulmonary nocardiosis?
Nocardiosis is a disease caused by bacteria found in soil and water. It can affect the lungs, brain, and skin. It is most common in people with weakened immune systems who have difficulty fighting off infections (for example, people with cancer or those taking certain medications such as steroids).
Is pulmonary nocardiosis contagious?
The infection can’t be spread from one person to another. Nocardiosis most commonly occurs in the lungs, but it may spread to other areas of the body, such as the: skin. digestive system.
Is Nocardia cyriacigeorgica an invasive pathogen?
Nocardia cyriacigeorgica is recognized as an emerging pathogen in many parts of the world. We present the first case description of invasive N. cyriacigeorgica pulmonary infection in the United States identified to the species level by 16S rRNA and hsp65 sequence analysis.
Is Nocardia cyriacigeorgica associated with Mycobacterium avium complex lung disease?
Here we report for the first time two cases of pulmonary nocardiosis caused by Nocardia cyriacigeorgica associated with Mycobacterium avium complex (MAC) lung disease caused by M. avium. Case 1 is that of a 72-year-old Japanese man with untreated MAC lung disease, who was diagnosed with rheumatoid arthritis and initiated on methotrexate.
Is pulmonary sequestration complicated with Nocardia cyriacigeorgica?
BACKGROUND Nocardia cyriacigeorgica (N. cyriacigeorgica) infection is uncommon in clinical practice. Pulmonary sequestration complicated with N. cyriacigeorgicahas not been reported in the literature. Here, we present a case of pulmonary se-questration complicated with N. cyriacigeorgicainfection in an immunocom-petent woman. CASE SUMMARY
What is the most common presentation of Nocardia infection?
Pulmonary nocardiosis is the most frequent presentation of infection by Nocardia species, associated with opportunistic infections in immunocompromised hosts, particularly in those with impaired cell-mediated immunity, although immunocompetent hosts can also present with pulmonary nocardiosis.
