Phenotypic characteristics, antimicrobial susceptibility profile, and clinical-epidemiological features of 28 Nocardia strains isolated from 19 cases of bovine mastitis, eight cutaneous-subcutaneous lesions and one case of pneumonia in dogs were evaluated. Microbiological, biochemical, cytological and scanning electron microscopy methods were used in diagnosis. Nocardia asteroides type IV, Noca...

A Western blot (immunoblot) assay is presented for the diagnosis of nocardiosis with a specific immunodominant 54-kilodalton (kDa) antigen purified from a culture filtrate of Nocardia asteroides by immunoaffinity chromatography. The chromatography column was prepared with immunoglobulin G obtained from sera from patients with lepromatous leprosy. Unbound solutes consisted of specific, partially...

We present the case of a patient with an infection by Nocardia which manifested itself with monocular endophthalmitis. Nocardia infection is not common and ocular involvement is one of the most uncommon presentations. In these cases it is very important to make an early diagnosis and intensive treatment to prevent the visual prognosis.

Nocardiosis is on the rise but hard to diagnose and the application of advanced subtyping technologies is called for. While the genomic sequence for the most virulent strain, Nocardia farcinica is available, proteome data are essentially non-existent. Nevertheless, they are necessary for functional studies on virulence and disease prevention. Here, comparative gel electrophoresis (PAGE)-based a...

The organism responsible for endocarditis of a prosthetic aortic valve was identified as Nocardia asteroides. The patient was treated with intravenous amikacin (250 mg four times a day) and intravenous imipenem (1.5 g four times a day). The valve was replaced under this new antibiotic regimen. This is the first report of survival after prosthetic valve nocardiosis.

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...

Cavitary pneumonia in immunocompromised patients is a challenging entity. Establishing accurate diagnosis and starting effective antibiotics are essential steps towards improving outcome. A 58-year-old stem cell transplant patient was admitted to the hospital with necrotizing pneumonia caused by nocardia. The disease progressed despite of aggrieve antimicrobial therapy. Nocardiosis continues to...

Methods The ocular samples viz., corneal swab, corneal scraping, aqueous tap and vitreous tap were processed for culture and the isolated Nocardia species were further confirmed for speciation by standard microbiological procedures. Antibiotic susceptibility analysis for the confirmed isolates of N. asteroides was performed by agar disk diffusion method following the guidelines of Clinical Labo...
