Cladosporium aecidiicola on spermogonia of Tranzschelia pruni-spinosae on Anemone ranunculoides is reported from Austria. It is the fi rst record of this species from spermogonia. Th e following new records are reported for the fi rst time: Merendera attica, as a new host of Urocystis colchici (from Bulgaria); Helleborus orientalis, as a new host o...

Trichophyton rubrum, T. mentagrophytes, T. verrucosum, Microsporum canis, M. gypseum and Epidermophyton flocoosum represent the cause of human dermatomycoses isolated most often at the University Hospital of Dermatology in Graz, Austria, between 1991 and 1998. So far, identification was mainly based on the cultivation of fungal isolates on special...

Trichophyton rubrum, T. mentagrophytes, T. verrucosum, Microsporum canis, M. gypseum and Epidermophyton flocoosum represent the cause of human determatomycoses isolated most often at the University Hospital of Dermatology in Graz, Austria, between 1991 and 1998. So far, identification was mainly based on the cultivation of fungal isolates on specia...

Ringworm of cattle still represents an important zoonosis, which is caused almost exclusively by Trichophyton verrucosum, a fungus adapted to ruminants through its parasitism. The cause of disease corresponds to that of a Dermatophytosis profunda and leads to immunity. Due to its ecological behaviour in infected livestock the causative agent can be...

This chapter focuses on the role played by ribosomal RNA/DNA sequence comparisons in assessing the phylogenetic relationships between the yeasts. The first extensive use of rRNA comparisons for yeast systematics was described by Bicknell and Douglas, who measured species divergence from the extent of reassociation between tritium-labeled 25S rRNA a...

Twenty-seven strains of Trichophyton verrucosum from 14 cattle herds in the Federal States of Thuringia and Mecklenburg-Vorpommern were examined by culture morphological and molecular biological (PCR fingerprinting, AFLP analysis sequencing of ITS region) methods. Six reference strains of the same species, among them the so-called album and ochrace...

The nucleotide sequence of the small-subunit rRNA (18S rRNA) coding gene in the higher fungus Protomyces inouyei contains two group I introns. This is the first report of two group I introns in the 18S rRNA coding region. Based on the comparison of the two introns of Protomyces inouyei with those of the green alga Ankistrodesmus stipitatus, and the...

Ribosomal RNA (rRNA) sequences represent a good taxonomic character. Even small but significant parts of rRNA molecules can be used as a basis for taxonomic conclusions. A highly variable region within the 28S ribosomal nucleotide sequences from various yeasts was analysed. Despite numerous nucleotide exchanges in this region the secondary structur...

Thirteen Bacillus strains containing ω-cyclohexane fatty acids isolated from different soils and from apple juice represent a new thermotolerant, acidophilic species named Bacillus acidoterrestris sp. nov. Obligate acidophily and their fatty acid profile distinguish the strains from Bacillus coagulans which is acidotolerant and possesses branched-c...

The 5S rRNA sequences from the Basidiomycetes Atractiella solani, Ceratobasidium cornigerum, Graphiola phoenicis, Phleogena faginea, Platygloea peniophorae, Septobasidium carestianum, Tulasnella violea and Uthatobasidium fusisporum were determined. Comparison of these sequences with all the other basidiomycetous sequences analyzed so far revealed t...

The programs offer the possibility of comparing pairs of homologous sequences in order to find out percentage of homology, number of identical deviating nucleotides, of transitions and transversions and, derived from these, KNUC-values according to Kimura (1) and the corresponding standard error sigmaK. The sequences can be printed in pairs underne...

The 18S and 5S ribosomal RNA genes are separated by a 582-nucleotide-long spacer region in the Oenothera mitochondrial genome. The 5S rRNA gene is 7 bp shorter than the maize and 3 bp shorter than the wheat sequences due to a 4 bp deletion in a side arm of the secondary structure model. The 18S rRNA molecule can be folded analogously to the maize a...

Summary The 5S ribosomal RNA nucleotide sequences from seven smut fungi, Ustilago hordei, U. longissima, U. maydis, U. scahiosae, Farysia thuemenii, Ginanniella primulicola and Sphacelotheca spec. , as well as from Rhodosporidium malvinellum were determined and compared with sequences from other basidiomycetous fungi. The 5S rRNA nucleotide sequenc...

The 5S ribosomal RNA nucleotide sequences of five basidiomycetous fungi, Coleosporium tussilaginis, Gymnosporangium clavariaeforme, Puccinia poarum, Endophyllum sempervivi and Microstroma juglandis were determined. Despite high differentiation in their host spectra the four rust species are highly conserved with respect to their 5S rRNA sequences,...

A variety of pseudomonad species have been characterized by the technique of oligonucleotide cataloging of 16S ribosomal RNA in order to determine their genealogical relationships to one another and to other Gram negative bacteria. By this criterion, pseudomonads are shown to comprise five distinct groupings (as originally defined by Palleroni and...

The technique of oligonucleotide cataloging shows the purple photosynthetic eubacteria to comprise three major subdivisions, temporarily called alpha, beta, and gamma--previously designated groups I-III by Gibson et al. (1979). Each subdivision contains a number of non-photosynthetic genera in addition to the photosynthetic ones. The alpha subdivis...

The G + C content of the DNA from 25 strains of various species of the parasitic Exobasidia (Basidiomycetes) ranges from 39.1 to 68.1 mol%. They can be ordered into ten distinct groups. Exobasidium vaccinii (65.8-68.1 mol% G + C) lives on various Vaccinium species causing mostly local infections. E. splendidum (48.0-51.7 mol% G + C) was found on th...

Description is provided of a new heterobasidiomycetous genus, Cystofilobasidium, based on Rhodosporidium capitatum. The genus is characterized by teliospores which give rise to filobasidiaceous basidia, sessile primary basidiospores which remain attached to the basidium, and a yeast phase developing from buds produced by the primary spores. Two spe...

Closed circular DNAs have been isolated from Oenothera and analysed by gel electrophoresis. A number of different size classes could be observed in the supercoiled fraction from the density gradient. The five smallest size classes of 6.3, 7.0, 8.2, 9.9, and 13.5 kilobases linear length were purified and their restriction fragment sizes compared. Th...

Graphiola phoenicis was restudied by light microscopy and investigated in detail with the scanning and the transmission electron microscopes. Hyphae of the fruitbody are mainly dikaryotic. Karyogamy occurs in cells which are interpreted as meiosporangia (basidia), and which develop in chains. Shortly after karyogamy, meiosis takes place in these ba...

Helical bacteria from the generaSpirillum, Oceanospirillum, Aquaspirillum, andAzospirillum—as well asSerpens flexibilis—were characterized by oligonucleotide cataloging of 16S rRNA in order to establish their phylogenetic relationships to one another and to Gramnegative bacteria in general. The various genera of helical bacteria are not specificall...
