Staphylococcus aureus, including methicillin-resistant S. aureus (MRSA), is an important human pathogen that produces a variety of toxins and causes a wide range of infections, including soft-tissue infections, bacteremia, and staphylococcal food poisoning. A loop-mediated isothermal amplification (LAMP) assay targeting the arcC gene of S. aureus was developed and evaluated with 119 S. aureus a...
BACKGROUND As the major burden of Buruli ulcer disease (BUD) occurs in remote rural areas, development of point-of-care (POC) tests is considered a research priority to bring diagnostic services closer to the patients. Loop-mediated isothermal amplification (LAMP), a simple, robust and cost-effective technology, has been selected as a promising POC test candidate. Three BUD-specific LAMP assays...
Canine monocytic ehrlichiosis (CME) is a common tick-borne disease caused by the rickettsial bacterium Ehrlichia canis (Rickettsiales: Anaplasmataceae). In view of the different stages and variable clinical signs of CME, which can overlap with those of other infections, a conclusive diagnosis can more readily be obtained by combining clinical and hematological evaluations with molecular diagnos...
A loop-mediated isothermal amplification (LAMP) assay using six primers targeting a highly conserved region of the B2L gene has been developed to diagnose orf virus. The assay produces a ladder-like pattern of products on an agarose gel that can be specifically digested with BsrGI enzyme. The sensitivity of the LAMP assay, which was determined to be a single copy of the standard plasmid, was 10...
This study reports the development of a loop-mediated isothermal amplification procedure (LAMP) for polymerase chain reaction (PCR)-based detection of 'Candidatus Liberibacter solanacearum', the bacterial causal agent of potato zebra chip (ZC) disease. The 16S rDNA gene of 'Ca. Liberibacter solanacearum' was used to design a set of six primers for LAMP PCR detection of the bacterial pathogen in...
چکیده زمینه و هدف: روش های مختلفی جهت تشخیص سالمونلا وجود دارد. اما روش هایی که بر پایه ی ژنوم و dna هستند، تکنیک های بهتری جهت تشخیص می باشند. pcr روشی سریع و حساس است و به علت کارایی بالا به طور گسترده ای در تشخیص سریع پاتوژن ها به کار گرفته می شود. اما دارای محدودیت هایی نیز می باشد (استفاده از دستگاه های مربوطه زمان و هزینه زیادی را می طلبد)، به همین دلیل جهت رفع این مشکلات روشی به کار گرفت...
مقدمه:سالمونلاها از مهمترین باکتری های بیماری و عامل تیفوئید، باکتریمی، آنتروکولیت و سالمونلوز است که از عفونت های مشترک انسان و حیوانات می باشد. بیماریهای ناشی از این عامل یک معضل بزرگ بهداشتی در جهان به خصوص در کشورهای در حال توسعه از جمله کشور ما می باشد. بنابراین تشخیص سریع، دقیق و به موقع آن برای جلوگیری از اپیدمی و عوارض مخرب این باکتری ضروری به نظر می رسد. برای تشخیص سالمونلا روش های مخت...
ABSTRACT Aim: One of the main diagnostic problems of conventional polymerase chain reaction (PCR) is indiscrimination of low parasitic loads in soil samples. The aim of this study is to determine the genetic diversity and identification of Toxocara spp. from public areas soil inferred by loop-mediated isothermal amplification (LAMP) assay. MATERIALS AND METHODS A total of 180 soil samples wer...
A loop-mediated isothermal amplification (LAMP) assay for the rapid detection of cytomegalovirus (CMV) was developed and evaluated. The LAMP assay specifically amplified only CMV DNA, and no cross-reactivity with the DNA of herpes simplex virus type 1, varicella-zoster virus, adenovirus, Aspergillus flavus, or Staphylococcus aureus was observed. The sequences of the LAMP assay-positive CMV prod...
BACKGROUND Buruli ulcer (BU) caused by Mycobacterium ulcerans (M. ulcerans) has emerged as an important public health problem in several rural communities in sub-Saharan Africa. Early diagnosis and prompt treatment are important in preventing disfiguring complications associated with late stages of the disease progression. Presently there is no simple and rapid test that is appropriate for earl...
