Corneal ulcers may become non-healing if inappropriately managed. Empirically giving broad spectrum antibiotics or prescription of a “cocktail” of topical antibacterial, antifungal and antiviral medication may only add to drug toxicity and drug resistance. We present a series of four cases of microbial keratitis which are complicated due to presence of more than one causative organism. Microbio...
OBJECTIVE To analyze the relationship between fluoroquinolone use at presentation and minimum inhibitory concentration in bacterial keratitis. METHODS The Steroids for Corneal Ulcers Trial was a randomized, double-masked, placebo-controlled trial assessing the effect of adjunctive topical corticosteroid treatment on outcomes in bacterial keratitis. After presentation, all patients were treate...
Background & Aims: Nocardia are gram-positive, aerobic, relative acid-fast, and opportunistic bacteria, and one of the causes of systematic infection around the world. The natural habitats of these bacteria are soil and dust. Hospitalized patients with immune deficiency are at high risk of transmission of opportunistic infection. Due to these facts and the complexities that exist in the isolati...
Detection of Nocardia Asteroides Complex in Clinical Isolates by Real-Time Polymerase Chain Reaction
Background and Aims: Nocardia asteroides complex is the most common cause of infectious diseases due to nocardiosis. Interspecies differentiation of Nocardia genera is essential for prognosis and timely proper treatment, as well as for epidemiological studies. Since each genus has its own antibiotic resistance, precise careful diagnosis is of prime importance. As compared to biochemical and phe...

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 روش ها: در این پژوهش، برای جداسازی از خاک، روش Slip-buried و برای استخراج DNA، روش Microwave oven استفاده شد و در این روشها، سو...
BACKGROUND Nocardia sp. causes a variety of clinical presentations. The incidence of nocardiosis varies geographically according to several factors, such as the prevalence of HIV infections, transplants, neoplastic and rheumatic diseases, as well as climate, socio-economic conditions and laboratory procedures for Nocardia detection and identification. In Brazil the paucity of clinical reports o...
introduction: nocardia is saprophytic soil bacterium of the actinomycetes families. nocardia has high diversity of species and due to species diversity of nocardia, phenotypic tests are essential for early identification of nocardia species. methods: 155 soil samples from different regions of north khorasan province in iran were collected, including: urban and rural areas. isolation of nocardia...
