Opis:
Rośliny ozdobne - tulipan, lilia, dalia i serduszka okazała (Dicentra spectabilis) - ze zmianami w zabarwieniu i deformacją liści i kwiatów, zaburzeniami w kwitnieniu i zamieraniem pąków kwiatowych oraz nadmiernym wybijaniem pędów bocznych, zostały przetestowane na obecność fitoplazm przy pomocy analizy PCR-RFLP. Do wykrywania fitoplazm zastosowano dwuetapową reakcję PCR - do pierwszego etapu użyto parę starterów uniwersalnych dla fitoplazm (P1/P7) a do drugiego trzy pary starterów uniwersalnych (R16F2n-R16R2, fA-rA, Pc399-P1694) oraz startery specyficzne dla fitoplazm z grupy żółtaczki astra (R16IF1-R16IR1) i proliferacji jabłoni (fAT-rAS). Identyfikację fitoplazm przeprowadzono na podstawie wyników analizy restrykcyjnej wykonanej przy użyciu sześciu enzymów (Hpall, Rsal, Alul, MseI, Sspl, oraz Hhal). Na postawie analizy PCR-RFLP w testowanych roślinach stwierdzono obecność dwóch grup fitoplazm. W tulipanach, serduszkach okazałych i jednej odmianie lilii wykryto fitoplazmy z grupy żółtaczki astra (AY, 16SrI), przy czym w serduszkach okazałych stwierdzono obecność fitoplazm z dwóch podgrup: I-B lub I- A, natomiast w lilii wykryto fitoplazmę z podgrupy I-A. Fitoplazmę z grupy proliferacji jabłoni (AP, 16SrX) wykryto w jednej odmianie lilii, natomiast w badanych daliach stwierdzono obecność mieszaniny fitoplazm AY i AP.
Diseased ornamental plants - tulips, lilies, dahlias and bleeding hearts (Di- centra spectabilis) - with symptoms of flower and leaf discolouration and malformation, flower bud deficiency and abnormal shoot production were tested for the presence of phytoplasmas using PCR-RFLP assay. Phytoplasmas were detected by two-step PCR assay. The first round was done using P1-P7 primer set, universal for phytoplasmas. The nested PCRs were done with universal (R16F2n-R16R2, fA-rA, Pc399-P1694) and aster yellows group-specific (R16IF1-R16IR1) or apple proliferation group-specific (fAT-rAS) primer pairs. Identification of phytoplasmas was accomplished through RFLP analysis using Hpall, Rsa\,Alu\, MseI, Sspl, or Hha\ endonucleases. On the basis of PCR-RFLP analysis, two different phytoplasma groups were identified in tested plants. Phytoplasmas belonging to the subgroup I-B or I-A of aster yellows group (AY, 16SrI) were found in samples collected from tulips, bleeding hearts and one lily cultivar. One lily cultivar was infected with phytoplasma from apple proliferation group (AP, 16SrX), whereas mix of two different phytoplasmas - belonging to AY and AP groups - were detected in the tested dahlias.

Opis:
Introduction and aim. Mutation(s) in the gene encoding the CD19 molecule affect CD19 protein expression and primary immunodeficiency (PID) occurs. The PCR-RFLP method, which is faster and cheaper than other mutation detection methods, is rarely used in the diagnosis of PID. The study aimed to genetically identify CD19 deficiency, which is a PID, using the PCR-RFLP method. Material and methods. A total of 8 patients and two healthy controls were included in the study and the relevant region genotypes in the CD19 gene were determined by performing PCR-RFLP analysis. Results. The index case, newborn baby and mother were also included in the study. It was determined that the index case (P6) was homozygous mutant, the newborn baby (P7) and mother (P8) had heterozygous genotype. Based on this situation, one child (P1) was found to be homozygous mutant, mother (P2), father (P3) and other children (P4 and P5) had heterozygous genotype in the family, which was determined to be related to the first case. Conclusion. In our study, it has been shown that PCR-RFLP is a method that can be used in the diagnosis of PID by determining genotypes using PCR-RFLP, and especially in terms of rapid genetic testing of family screenings.

Opis:
Thrips from the genus Frankliniella (Thysanoptera, Thripidae) are phytophagous on crops and wild plants. Some of them cause slight economic damage, however, others including F. occidentalis and F. intonsa are responsible for considerable losses in crop production. Moreover, they constitute a double threat for host plants by not only feeding on them but also vectoring viruses, some of which are on the quarantined list of the European Plant Protection Organization. The rapid detection and differentiation between more and less harmful Frankliniella species is, therefore, important in order to combat the pests at the time of their appearance. In this study, we have undertaken to develop a method of detecting F. occidentalis, F. intonsa, F. pallida, and F. tenuicornis. The protocol is based on PCR amplification of ITS1 rDNA fragments of these insects using universal primers pair giving products of slightly distinct length for studied insects. Restriction enzymes digestion which is easy to interpret, allows for visible differentiation of all these Frankliniella species. The method was shown to be species-specific and sensitive. Even single specimens in either the larvae or adult stage could be distinguished.

Opis:
Haemophilus parasuis belongs to opportunistic microorganisms of undefined virulence. The purpose of the studies was to compare suitability of PCR/RFLP in our modification and ERIC PCR for epidemiological study of domestic strains of H. parasuis. The results were evaluated taking into account two different aspects: suitability of the tests for isolating the highest possible number of clone groups and subjective evaluation of the method judged with respect to the following criteria: difficulty, availability of equipment and reagents as well as time and cost of the study. The results obtained in the present study show that the two methods used for typing of H. parasuis had high discriminatory power. Taking into account this parameter it can be concluded that ERIC PCR is more suitable than PCR/RFLP. This justifies the use of ERIC PCR for routine epidemiological analyses of mentioned pathogen. Taking into account the complexity of method used, ERIC-PCR based on random amplification of DNA, proved to be comparable to PCR/RFLP. The last mentioned technique is relatively less expensive and labour-consuming, especially when diagnostic PCR method is used for the epidemiological studies.

The aim of this study was molecular identification of S. aureus strains isolated from mastitic milk samples and establishing the genetic relationship between strains isolated from cows belonging to the same herd. In all 43 isolated strains the gap gene (930 bp) was amplified, which enabled their affiliation to the Staphylococcus genus to be established. PCR-RFLP with AluI endonuclease of the gap gene as well as nuc (450 bp) and coa (1130 bp) gene amplification allowed precise S. aureus species identification. One hundred percent of the genetic relationship between strains was established via RAPD-PCR and coa-typing.

Opis:
Genetic variability of three sympatric crucian carp ( Carassius carassius ) populations from NW Poland was studied within a research project aimed at assessing the utility of those populations for stocking in inland waters. DNA samples were collected from 65 individuals. Restriction analysis was performed using 4 enzymes (HaeIII, HinfI, FspBI, TasI) of known restriction sites. The restriction pro files obtained were classified as belonging to a single haplotype (H-1). Selected DNA products were sequenced; the subsequent comparison made it possible to detect the presence of substi- tutions in the genome fragment analysed.

Opis:
The goal of work was identification A1 variant of bovine beta casein which involves ischemic heart disease and diabetes mellitus in human. The digestion of A1beta casein can result in the production of bioactive beta casomorphin-7 (BCM-7); this is not the case with A2. This bioactive peptide has been linked to physiological traits that may elicit effects on components of the vascular and immune systems. The material involved 111 Slovak Spotted breed. Bovine genomic DNA was extracted from whole blood by using commercial kit, and used in order to estimate beta-casein genotypes by means of PCR-RFLP method. The PCR products were digested with DdeI restriction enzyme. In the population included in the study were detected all three genotypes, homozygote genotype A1A1 (14 animals), heterozygote genotype A1A2 (37 animals) and homozygote genotype A2A2 (60 animals). In the total population of cattle homozygotes A2A2-0.5405 were the most frequent, while homozygotes A1A1-0.1261 were the least frequent ones. This suggests a superiority of allele A2 (0.7072) which does not produce BCM-7, and thus is safe for human consumption. The expected homozygosity for gene CSN2 is in the population stated a slight increase in homozygosity (0.5858). This caused a slight decrease in the level of possible variability realization (41.80%), which corresponds to the effective number of alleles (1.7071).

Opis:
Background. The occurrence of clarithromycin resistance among Helicobacter pylori strains is a major cause of the treatment failure. Resistance to this drug is conferred by point mutations in 23S rRNA gene and the most prevalent mutations are A2143G and A2142G. The aim of the study was to evaluate the occurrence of A2143G and A2142G mutations in a group of H. pylori strains resistant to clarithromycin. Materials and Methods. The study included 21 clarithromycin-resistant H. pylori strains collected between 2006 and 2009 in southern Poland. Resistance to clarithromycin was quantitatively tested with the E-test to determine the minimal inhibitory concentration (MIC value). The point mutations of H. pylori isolates were detected by PCR followed by RFLP analysis. Results. The MIC values for clarithromycin for the analyzed strains ranged from 1.5 mg/L to 64 mg/L. Nine H. pylori strains exhibited A2143G mutation and A2142G mutation was found in 9 isolates as well. The results of RFLP analysis of 3 clarithromycin-resistant strains were negative for both mutations. The average MIC values for A2143G and A2142G mutants were 6 and 30 mg/L, respectively. Conclusions. Frequencies of A2143G and A2142G mutations were the same in all isolates tested. Strains with A2143G mutation exhibited lower MIC values than A2142G mutants. Application of PCR-RFLP method for detection of clarithromycin resistance allows for better and more efficient management of H. pylori infections.
