Prokaryotic diversity increases every year with each new described species. Since the first discoveries of microorganisms, researchers’ endeavours are dedicated to the systematisation of all known living organisms in a consistent taxonomy. Originally based on morphology, in recent years modern taxonomy develops thanks to the implemenation of new discoveries in the fields of biochemistry and genetics. In the last thirty years, ribotyping was the leading technique used to classify

Bacillus cereus sensu lato is a group of several species of Gram-positive sporeformers ubiquitous in nature and showing huge impact on human activities. They are often found in soil, air, plant material, animal tissues and digestive tracts as well as in food products. Their genetic similarities and frequent horizontal gene transfer causes doubts regarding their taxonomy. In addition, their toxicity and psychrotolerance constitute serious problems in the dairy industry, being responsible for

Materials and methods
Nematode extraction and processing
Nematodes were obtained from soil samples using a modified Baermann (1917) funnel technique, killed by heating, fixed in a 4% formalin solution, transferred to pure glycerine following the technique of Siddiqi (1964), and mounted on glass slides for observation.
Light microscopy
Observations were made using a Leitz Laborlux S (Leitz, Wetzlar, Germany) microscope and a Nikon Eclipse 80i (Nikon, Tokio, Japan

Sudhaus and Hooper (1994) provided new ideas about the taxonomy and the phylogeny of several rhabditid species: (i) accepted Oscheius as a subgenus of Rhabditis, (ii) regarded it as a monophyletic taxon based on three synapomorphies (long female rectum, terminal duct of the excretory system forwards coiled and with heavily sclerotized wall, and several features of spicule shape), (iii) considered Dolichorhabditis (Andrássy, 1983) as a junior synonym of Oscheius, and (iv

The taxonomy and the systematics of the genus Makatinus are discussed by means of the characterization of its morphological pattern and the first molecular (D2–D3 expansion segments of 28S rDNA) analysis of a representative of this taxon, Makatinus crassiformis from Costa Rica. The presence of two or more pairs of male ad-cloacal genital papillae is the most characteristic autapomorphy of the genus, but the status of its species on this concern differ among them. Both morphological and

Numerical taxonomy was used for identification and grouping of the genera, species, and populations in the families Merliniidae and Telotylenchidae. The variability of each of 44 morphometric characters was evaluated by calculation of the coefficient of variability (CV) and the ratio of extremes (max/min) in the range of 1,020 measured females. Also correlation and regression analyses were made between characters to find potential collinearities. Hierarchical cluster analysis (HCA

In the nematode family Criconematidae, a taxonomy primarily based on cuticle characters has created classifications that are notoriously volatile. Molecular characters may lead to their stabilization. A phylogenetic tree of Criconematoidea was constructed using 166 new near full-length 18S rDNA sequences and 58 sequences from GenBank. Bayesian and maximum likelihood (ML) analyses produced trees with similar topologies. Major features include a strongly supported clade that includes

Metschnikowia spp. are extensively studied “non-conventional” yeasts. Strains belonging to these genera are considered as non-pathogenic and safe. The unique properties of Metschnikowia spp. allow us to look at these microorganisms as a promising subject for evolutionary genetics, taxonomy, ecology, as well as a natural biocontrol agent in biotechnology. This article provides a synthesis of the systematics, morphology, ecology and physiology of Metschnikowia spp., with special

Staphylococci are pathogenic bacteria often isolated from clinical material obtained from animals. Unlike in human medicine, in veterinary sciences various species of coagulase-positive staphylococci have been isolated from clinical specimens. In addition to Staphylococcus aureus and Staphylococcus pseudintermedius, other species are also often identified. Recently, the taxonomy of staphylococci has been updated, therefore, it is now important to recognize also the new species. Currently

Taxonomy of Heterodera species has been revised extensively in the past; Baldwin and Mundo-Ocampo (1991) placed 23 Heterodera species into Goettingiana group. However, Sturhan (1998) and Subbotin et al. (2001) used J2’s lateral field characters and host preferences

Globally, cyst nematodes species cause serious damage to a wide variety of economically important crops. The need for information on cyst-forming nematode species has been instrumental in stimulating growth of nematology worldwide. The cyst nematode group currently contains eight genera, with a total of 121 valid species (Handoo and Subbotin, 2018).

Originally proposed to accommodate 12 species previously included in Eudorylaimus Andrássy, 1959 its taxonomy was later updated by several authors (Andrássy, 1992; Jairajpuri and Ahmad, 1992; Vinciguerra, 2006; Andrássy, 2009). More recently, Ahmad et al. (2016) presented an emended diagnosis, a list of 15 valid species with a key to their identification, and a compendium of their more relevant morphometrics.
