PCR-ELISA: inexpensive alternative to quantitative PCR
PublicationPCR-ELISA (polymerase chain reaction-enzyme linked immunosorbent assay), a combination of PCR and ELISA methods, has been used since late 1980s. The technique is based on specially labelled DNA fragments which are captured by specific DNA sequences and detected by antibodies. The whole procedure of PCR-ELISA is divided into three steps: DNA extraction, PCR reaction and detection by ELISA. The method has been found as very specific...

Specific detection of Alternaria alternata by PCR and real-time PCR
PublicationFungi of Alternaria genus are cosmopolitan organisms, which spores can be found in the air, soil, water, clothing and food. They commonly occur as saprotrophs on the plant remains, contributing to the decomposition of organic matter. Additionally, they are components of the normal human and animal skin flora. Alternaria spp. are also known human allergens, causing hay fever and allergic reactions that can lead to the development...

PCR and real-time PCR assays to detect fungi of Alternaria alternata species
PublicationFungi of the Alternaria genus are mostly associated with allergic diseases. However, with a growing number of immunocompromised patients, these fungi, with A. alternata being the most prevalent one, are increasingly recognized as etiological agents of infections (phaeohyphomycoses) in humans. Nowadays, identification of Alternaria spp. requires their pure culture and is solely based on morphological criteria. Clinically, Alternaria...

PCR melting profile (PCR MP) - a new tool for differentiation of Candida albicans strains
PublicationPo raz pierwszy przedstawiliśmy użyteczność techniki PCR MP opartej na metodzie ligacji adaptorów (LM PCR) i obniżonej temperaturze denaturacji w cyklach PCR do wewnątrzgatunkowego różnicowania szczepów Candida albicans. Przebadaliśmy 123 szczepy Candida albicans z zastosowaniem trzech metod genotypowania: PCR MP, REA-PFGE i RAPD i uzyskaliśmy odpowiednio 27, 26 i 25 unikalnych genotypów. Zaprezentowane dane pokazały, że technika...

Technika PCR MP (PCR Melting Profile) - możliwości zastosowania w badaniach epidemiologicznych
PublicationUżyteczność PCR MP (ang. PCR Melting Profile), stosunkowo nowej techniki różnicowania genetycznego szczepów mikroorganizmów, pokazano na przykładach badań epidemiologicznych, dotyczących wykrywania zakażeń szpitalnych, analizy sytuacji epidemiologicznej i identyfikacji transmisji bakteryjnej u poszczególnych pacjentów. Technikę PCR MP charakteryzuje prostota, niskie koszty wykonania oraz potencjał różnicujący porównywalny do metody...

PCR detection of Scopulariopsis brevicaulis
PublicationScopulariopsis brevicaulis is known as a most common etiological factor of the mould toenail infections. There are also reports indicating that S. brevicaulis could cause organ and disseminated infections. Nowadays microscopic observations from the direct sample and culture are crucial for the appropriate recognition of the infection. In this paper is presented a PCR-based method for S. brevicaulis detection. The specificity of...

A comparative evaluation of PCR ribotyping and ERIC PCR for determining the diversity of clinical Pseudomonas aeruginosa isolates
PublicationW pracy porównano dwie metody stosowane do badania różnorodności genetycznej drobnoustrojów. Modelem do badań była grupa 62 klinicznych izolatów bakterii P. aeruginosa. Zdecydowanie wyższy potencjał różnicujący stwierdzono w przypadku metody ERIC PCR, której zastosowanie pozwoliło na wyodrębnienie 36 różnych genotypów. W przypadku rybotypowania wyróżniono tylko 9 genotypów.

Optimised five-hour multiplex PCR test for the detection of Tinea ungium: performance in a routine PCR laboratory
PublicationWe recently published the development of a 5-hour multiplex PCR test for the detection of dermatophyte nail infection. We have optimized this test by inclusion of an inhibition control and evaluated the test in a routine laboratory when compared to the conventional microscopy and culture. A total of 109 clinical samples received at the mycology reference lab at Statens Serum Institute were included. The samples were divided equally...

Optimized 5-hour multiplex PCR test for the detection of tinea unguium: performance in a routine PCR laboratory
PublicationWe recently reported the development of a 5-hour multiplex PCR test for the detection of tinea unguium and the optimization of this test by the inclusion of an inhibition control. Here we report the performance of this procedure as used in a routine clinical laboratory as compared to conventional microscopy and culture-based techniques performed in a mycology reference laboratory. We found in processing 109 samples that 22 (20.2%)...
