Pulmonary intracavitary infection caused by Nocardia is an opportunistic infection and is believed to be a rare entity. We describe a case report of a patient with culture positive Nocardia asteroides who presented with complaints of cough and expectoration with episodes of haemoptysis and dyspnoea. The diagnosis of nocardiosis was made by microscopic examination of the surgically resected port...

Psoas muscle abscess is an uncommon infection that have been diagnosed increasingly in the last years. We present a case of a patient with advanced human immunodeficiency virus infection who developed a disseminated infection due to Nocardia asteroides sensu stricto type VI with psoas abscess. To our knowledge no other cases of Nocardia psoas abscess in the setting of HIV infection have been re...

purpose: to report the clinical, confocal scan, and histopathologic features of bilateral nocardia keratitis following photorefractive keratectomy (prk). case report: a 23-year-old girl underwent simultaneous bilateral prk for myopia. on the third postoperative day, dense central infiltrates mainly involving the anterior stroma were noticed in both eyes. clinical and confocal scan features were...

A rare case of culture-positive Nocardia canaliculitis is reported that presented with a history of chronic conjunctivitis and epiphora for the last 1.4 years, refractory to multiple treatment courses. Chronic conjunctivitis and a pouted punctum were observed in the right lower eyelid. Probing and sac syringing was performed. The "Sulfur granules" were expressed and subjected to various microbi...

We describe a rare case of anterior paramediastnial abscess due to Nocardia cyriacigeorgica in an immunocompetent patient without pre-existing lung disease. High suspicious should be taken in those patients that failed to improve after first course of antibiotic therapy. Similarly, when suspected, isolation is crucial because of the variation in antibiotic susceptibilities among Nocardia spp. i...

Nocardia asteroides was isolated after prolonged culture from the pericardial fluid of a human immunodeficiency virus-infected patient. The lengthy duration required for culture growth and identification of this N. asteroides isolate affected both initial therapeutic decisions and patient management. A proposed algorithm for the microbiological workup of pericardial fluid for possible Nocardia ...

A novel actinomycete strain YIM 33361(T) was isolated from a soil sample collected from Yunnan, China. Comparative 16S rRNA gene sequencing showed that the strain constituted a distinct subclade within the genus Nocardia, displaying more than 3% sequence divergence from established species. Based on its morphological, chemotaxonomic, phenotypic and genotypic characteristics, strain YIM 33361(T)...

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...

Exposure to 0.5% N-acetyl-L-cysteine (NAC), 2% NaOH-NAC, or benzalkonium chloride in trisodium phosphate (Zephiran-TSP) was toxic for Nocardia isolates. The number of viable Nocardia cells in a standardized suspension was reduced by 10(2) to 10(6) after a 30-min exposure to 2% NaOH-NAC and by 10(4) or more after a 30-min treatment with Zephiran-TSP.
