Abstract:
During an investigation of ascomycetous fungi on bamboos in Sichuan province, China, a new coelomycetous species, Pseudorobillarda sichuanensis was found on dead culms of Bambusa sp. and described. The new taxon differs from other Pseudorobillarda species in having paraphyses, subcylindrical conidiogenous cells, subcylindrical to naviculate, aseptate, guttulate conidia with 3-4 apical appendages.

Abstract:
During a survey on the biodiversity of plant-parasitic nematodes in Khuzestan province (southwest Iran), Ditylenchus filimus was discovered in the rhizosphere of date palm. The morphological and morphometric data were provided for the recovered species. The morphological characters of Iranian population are in agreement with the type population and other populations of this species. Molecular phylogenetic analyses of the species with representatives of the family Anguinidae were discussed using partial sequences of the small subunit, D2-D3 expansion segments of the large subunit, and internal

AbstractThe Angiostrongylus lungworms are of public health and veterinary concern in many countries. At the family level, the Angiostrongylus lungworms have been included in the family Angiostrongylidae or the family Metastrongylidae. The present study was undertaken to determine the usefulness and suitability of the nuclear 18S (small subunit, SSU) rDNA sequences for differentiating various taxa of the genus Angiostrongylus, as well as to determine the systematics and phylogenetic relationship of Angiostrongylus species and other metastrongyloid taxa. This study revealed six 18S (SSU) haploty

Abstract:
The complete sequence of the 18S small subunit (SSU) ribosomal DNA of Hammondia hammondi and Sarcocystis mucosa was obtained and compared to SSU rDNA sequences of Neospora caninum, Toxoplasma gondii, Besnoitia besnoiti, 2 species of Frenkelia, 3 species of Isospora, and 13 species of Sarcocystis. Analyses showed that H. hammondi and T. gondii are monophyletic and that these taxa shared a common ancestor with N. caninum and B. besnoiti. The weight of evidence shows that S. mucosa, S. neurona, and Frenkelia species form a clade thereby supporting the conclusion that Sarcocystis is paraphyletic.

Abstract:
For the past 100 years the phylogenetic affinities ofRhinosporidium seeberi have been controversial. Based on its morphological features, it has been classified as a protozoan or as a member of the kingdom Fungi. We have amplified and sequenced nearly a full-length 18S small-subunit (SSU) ribosomal DNA (rDNA) sequence fromR. seeberi. Using phylogenetic analysis, by parsimony and distance methods, of R. seeberi’s 18S SSU rDNA and that of other eukaryotes, we found that this enigmatic pathogen of humans and animals clusters with a novel group of fish parasites referred to as the DRIP clade (Derm

ABSTRACT A cultivation-independent technique for genetic profiling of PCR-amplified small-subunit rRNA genes (SSU rDNA) was chosen to characterize the diversity and succession of microbial communities during composting of an organic agricultural substrate. PCR amplifications were performed with DNA directly extracted from compost samples and with primers targeting either (i) the V4–V5 region of eubacterial 16S rRNA genes, (ii) the V3 region in the 16S rRNA genes of actinomycetes, or (iii) the V8–V9 region of fungal 18S rRNA genes.

&lt;em&gt;ABSTRACT. Myxobolus cerebralis &lt;/em&gt;possesses unique phenotypic and genotypic characteristics when compared with other histozoic parasites from the phylum Myxozoa. The parasite infects the cartilage and thereby induces a serious and potentially lethal disease in salmonid fish. Comparisons of the small subunit ribosomal DNA (ssu rDNA) sequences of &lt;em&gt;M. cerebralis &lt;/em&gt;to other myxozoans demonstrate that the parasite has evolved separately from other &lt;em&gt;Myxobolus &lt;/em&gt;spp. that may appear in cartilage or nervous tissues of the fish host. &lt;em&gt;Myxob
