مقدمه: جنس نوکاردیا جزو اکتینومیستهای هوازی هستند که یک گروه بزرگ از باکتریهای ساکن خاک را شامل میشوند، که در جهان پخش شدهاند. در این مطالعه، با استفاده از آزمونهای تشخیصی رایج، مرسوم و مولکولی گوناگون، چندین ایزولههای نوکاردیا جداسازی و تشخیص داده شد. مواد و روشها: در این پژوهش، برای جداسازی از خاک، روش slip-buried و برای استخراج dna، روش microwave oven استفاده شد و در این روشها، سویه...
Authors of the present letter reviewed the letter conducted by Fatahi-Bafghi entitled as "Phenotypic and molecular identification of nocardia in brain abscess."[3] Nocardia is a filamentous bacteria, branched Gram‐positive Bacilli, aerobic, and partially acid-fast, and its diagnosis depends on staining and culture.[4] In this case, microscopic study of the brain abscess specimen revealed, long ...
New methodologies were developed for the identification of Nocardia but the initial diagnosis still requires a fast and accurate method, mainly due to the similarity to Mycobacterium, both clinical and bacteriologically. Growth on Löwenstein-Jensen (LJ) medium, presence of acid-fast bacilli through Ziehl-Neelsen staining, and colony morphology can be confusing aspects between Nocardia and Mycob...
Meningitis occurs throughout Egypt and is largely attributed to bacterial pathogens, but there is little information on fungal etiologies of meningitis. We, therefore, investigated fungal infections among Egyptian patients with acute and subacute meningitis who tested negative for bacterial and viral agents. A total of 1000 cerebrospinal fluid (CSF) samples collected from nine governorates of E...
BACKGROUND Nocardiosis is a rare, life-threatening opportunistic infection, affecting 0.04% to 3.5% of patients after solid organ transplant (SOT). The aim of this study was to identify risk factors for Nocardia infection after SOT and to describe the presentation of nocardiosis in these patients. METHODS We performed a retrospective case-control study of adult patients diagnosed with nocardi...
BACKGROUND Chronic granulomatous disease (CGD) is due to defective nicotinamide adenine dinucleotide phosphate oxidase activity and characterized by recurrent infections with a limited spectrum of bacteria and fungi as well as inflammatory complications. To understand the impact of common severe infections in CGD, we examined the records of 268 patients followed at a single center over 4 decade...
BACKGROUND Infections caused by Nocardia farcinica are uncommon and show a great variety of clinical manifestations in immunocompetent and immunocompromised patients. Because of its unspecific symptoms and tendency to disseminate it may mimic the clinical symptoms and radiologic findings of a tumour disease and the diagnosis of nocardiosis can easily be missed, because there are no characterist...
Nocardia otitidiscaviarum was seldom reported to cause primary cutaneous nocardiosis, which is difficult to diagnosis due to its nonspecific clinical features. Misdiagnosis of the disease could result in inappropriate treatment and chronic protracted lesions. In this report, we described a previously misdiagnosed case of primary cutaneous nocardiosis caused by N. otitidiscaviarum in a 30-year-o...
Nocardia transvalensis complex includes a wide range of microorganisms with specific antimicrobial resistance patterns. N. transvalensis is an unusual Nocardia species. However, it must be differentiated due to its natural resistance to aminoglycosides while other Nocardia species are susceptible. The present report describes a Nocardia species involved in an uncommon clinical case of a patient...
Pulmonary nocardiosis is a severe and uncommon opportunistic infection caused by Nocardia species. We present a patient with cryptogenic organizing pneumonia who was receiving long-term immunosuppressive therapy, whose treatment course was complicated by cutaneous and pulmonary nocardiosis. Tissue cultures confirmed Nocardia brasiliensis. Nocardiosis should be a diagnostic consideration for pat...
