Opis:
Application of the correct methods of study is essential for a proper description and understanding of natural communities of microorganisms and their relationships. Classical methods used for detection and identification of soil microorganisms resulted in underestimation of the microbiota. It has been claimed that classical methods, based mainly on morphology, led to the identification of only 1% of the soil microbiota, usually species that predominate in culture because of their fast growth and abundant sporulation. Molecular methods allow rapid, accurate, sensitive and cost−effective identification and enumeration of microorganisms. They are designed to replace and/or support classical approaches. This review summarizes some of the current and emerging nucleic acid−based molecular approaches used for detection, discrimination and quantification of microbes in the environment, mostly in soil.

Toxocara
Opis:
Toxocarosis is still an important and actual problem in human medicine. It can manifest as visceral (VLM), ocular (OLM) or covert (CT) larva migrans syndroms. Complicated life cycle of Toxocara, lack of easy and practical methods of species differentiation of the adult nematode and embarrassing in recognition of the infection in definitive hosts create difficulties in fighting with the infection. Although studies on human toxocarosis have been continued for over 50 years there is no conclusive answer, which of species - T. canis or T. cati constitutes a greater risk of transmission of the nematode to man. Neither blood serological examinations nor microscopic observations of the morphological features of the nematode give the satisfied answer on the question. Since the 90-ths molecular methods were developed for species identification and became useful tools being widely applied in parasitological diagnosis. This paper cover the survey of methods of DNA analyses used for identification of Toxocara species. The review may be helpful for researchers focused on Toxocara and toxocarosis as well as on detection of new species. The following techniques are described: PCR (Polymerase Chain Reaction), RFLP (Restriction Fragment Length Polymorphism), RAPD (Random Amplified Polymorphic DNA) and SSCP (Single Strand Conformation Polymorphism).

Opis:
American paddlefish (Polyodon spathula) is a new species in Polish aquaculture, its broodstocks are few and small, and it is possible that all mature fish originated from only a few spawners. Studies on polymorphism of highly variable microsatellite DNA allow revealing genetic characteristics of individual spawners as well as estimation of genetic variation within and divergence between broodstocks. This paper describes optimised protocols for isolation of DNA from fin tissues, amplification of nine microsatellite loci using PCR technique, and for fish genotyping using automatic capillary DNA sequencer. Our technique was tested towards the fin samples taken from all paddlefish reared in Poland and approaching their sexual maturity; the study included also samples taken from 47 fish of the Ukrainian breeding center (Gorny Tykich).
