Pulmonary tuberculosis and pulmonary nocardiosis are similar in most clinical symptoms and radiological manifestation. In the developing countries like Egypt where tuberculosis is very common, anti-tuberculosis drugs are started on basis of radiology and clinical symptoms. This study included 600 sputum specimens collected from 200 patients diagnosed as pulmonary tuberculosis from three chest h...

Background. Risk factors for Nocardia infection in organ transplant recipients have not been formally assessed in the current era of transplantation. Methods. We performed a matched case-control study (1:2 ratio) between January 1995 and December 2005. Control subjects were matched for transplant type and timing. Univariate matched odds ratios were determined and conditional logistic regression...

Nocardia is a ubiquitous microorganism related to pyogranulomatous infection, which is difficult to treat in humans and animals. The occurrence of the disease is on the rise in many countries due to an increase in immunosuppressive diseases and treatments. This report of cases from Brazil presents the genotypic characterization and the antimicrobial susceptibility pattern using the disk-diffusi...

PURPOSE The purpose of this study is to describe the diagnosis, course, and outcome of a case of Acanthamoeba and Stenotrophomonas keratitis with a fungal keratitis in the contralateral eye. METHODS A case of Acanthamoeba and Stenotrophomonas keratitis was diagnosed with confocal microscopy and cultures with confocal diagnosis of fungal keratitis in the fellow eye. RESULTS During the initia...

BACKGROUND Cystic fibrosis (CF) patients are predisposed to infection and colonization with different microbes. Some cause deterioration of lung functions, while others are colonizers without clear pathogenic effects. Our aim was to understand the effects of Nocardia species in sputum cultures on the course of lung disease in CF patients. MATERIAL AND METHODS A retrospective study analyzing t...

Nocardia species are ubiquitous in natural environments and can cause nocardiosis. Trimethoprim-sulfamethoxazole has long been the monotherapy treatment of choice, but resistance to this treatment has recently emerged. In this study, we used microplate Alamar Blue assays to determine the antimicrobial susceptibility patterns of 65 standard Nocardia isolates, including 28 type strains and 20 cli...

PURPOSE To determine the influence of risk factors, climate, and geographical variation on the microbial keratitis in South India. METHODS A retrospective analysis of all clinically diagnosed infective keratitis presenting between September 1999 and August 2002 was performed. A standardised form was filled out for each patient, documenting sociodemographic features and information pertaining ...

The properties of 42 strains of nocardoid (nocardioform) bacteria were compared. The results indicate that the organism previously called Nocardia turbata does not belong to the genus Nocardia nor does it fit into any of the previously described genera.

We report here brain abscesses caused by Nocardia beijingensis in a 59-year-old-Thai male with human immunodeficiency virus (HIV) infection presenting with progressive right sided hemiparesis. A computed tomography scan of the brain showed multiple brain abscesses. A stereotactic brain biopsy and 16S rRNA sequencing showed Nocardia beijingensis. The patient was treated with trimethoprim-sulfame...

Nocardial infection is caused by soil-borne aerobic bacteria. Nocardia in ischiorectal abscess is a rare presentation. Here, we present a case of ischiorectal abscess in an immunocompetent male patient with a history of trauma. The isolate was identified as Nocardia asteroides by standard methods. The patient responded well to amikacin and surgical drainage. Thus, this case highlights the impor...
