Description of three novel Lagenidium (Oomycota) species causing infection in mammals.

ABSTRACT: Recent molecular phylogenetic analysis of Lagenidium strains recovered from subcutaneous lesions in cats, dogs, and a human with lagenidiosis resolved into four clades; one of them was Lagenidium giganteum, but three others were novel.Due to the recent increase in L. giganteum infections from mammals, we studied 21 Lagenidium strains isolated from dogs and a human available in our collection.Molecular phylogenetic studies and phenotypic characteristics were used to characterize the strains.We report the finding of three novel species, herein designated as Lagenidium ajelloi, sp. nov., Lagenidium albertoi sp. nov, and Lagenidium vilelae sp. nov. Their morphological and growth features are also presented.Our study revealed the presence of three novel Lagenidium species infecting mammals.

Lagenidium giganteum pathogenicity in mammals.

Project description:Infections of mammals by species in the phylum Oomycota taxonomically and molecularly similar to known Lagenidium giganteum strains have increased. During 2013-2014, we conducted a phylogenetic study of 21 mammalian Lagenidium isolates; we found that 11 cannot be differentiated from L. giganteum strains that the US Environmental Protection Agency approved for biological control of mosquitoes; these strains were later unregistered and are no longer available. L. giganteum strains pathogenic to mammals formed a strongly supported clade with the biological control isolates, and both types experimentally infected mosquito larvae. However, the strains from mammals grew well at 25°C and 37°C, whereas the biological control strains developed normally at 25°C but poorly at higher temperatures. The emergence of heat-tolerant strains of L. giganteum pathogenic to lower animals and humans is of environmental and public health concern.

Molecular Description of a Novel Orientia Species Causing Scrub Typhus in Chile.

Project description:Scrub typhus is a potentially fatal rickettsiosis caused by Orientia species intracellular bacteria of the genus Orientia. Although considered to be restricted to the Asia Pacific region, scrub typhus has recently been discovered in southern Chile. We analyzed Orientia gene sequences of 16S rRNA (rrs) and 47-kDa (htrA) from 18 scrub typhus patients from Chile. Sequences were ≥99.7% identical among the samples for both amplified genes. Their diversity was 3.1%-3.5% for rrs and 11.2%-11.8% for htrA compared with O. tsusugamushi and 3.0% for rrs and 14.8% for htrA compared with Candidatus Orientia chuto. Phylogenetic analyses of both genes grouped the specimens from Chile in a different clade from other Orientia species. Our results indicate that Orientia isolates from Chile constitute a novel species, which, until they are cultivated and fully characterized, we propose to designate as Candidatus Orientia chiloensis, after the Chiloé Archipelago where the pathogen was identified.

Lagenidium sp. ocular infection mimicking ocular pythiosis.

Project description:This is a report of a Lagenidium sp. in a Thai patient who was diagnosed with severe keratitis that was unresponsive to antibacterial and antifungal drugs. Examination of a corneal biopsy specimen confirmed the presence of aseptate hyphae. The internal transcribed spacer DNA sequence of the strain isolated showed 97% identity with Lagenidium giganteum and other Lagenidium species.

Expanding the verrucomicrobial methanotrophic world: description of three novel species of Methylacidimicrobium gen. nov.

Project description:Methanotrophic Verrucomicrobia have been found in geothermal environments characterized by high temperatures and low pH values. However, it has recently been hypothesized that methanotrophic Verrucomicrobia could be present under a broader range of environmental conditions. Here we describe the isolation and characterization of three new species of mesophilic acidophilic verrucomicrobial methanotrophs from a volcanic soil in Italy. The three new species showed 97% to 98% 16S rRNA gene identity to each other but were related only distantly (89% to 90% on the 16S rRNA level) to the thermophilic genus Methylacidiphilum. We propose the new genus Methylacidimicrobium, including the novel species Methylacidimicrobium fagopyrum, Methylacidimicrobium tartarophylax, and Methylacidimicrobium cyclopophantes. These mesophilic Methylacidimicrobium spp. were more acid tolerant than their thermophilic relatives; the most tolerant species, M. tartarophylax, still grew at pH 0.5. The variation in growth temperature optima (35 to 44°C) and maximum growth rates (µmax; 0.013 to 0.040 h(-1)) suggested that all species were adapted to a specific niche within the geothermal environment. All three species grew autotrophically using the Calvin cycle. The cells of all species contained glycogen particles and electron-dense particles in their cytoplasm as visualized by electron microscopy. In addition, the cells of one of the species (M. fagopyrum) contained intracytoplasmic membrane stacks. The discovery of these three new species and their growth characteristics expands the known diversity of verrucomicrobial methanotrophs and shows that they are present in many more ecosystems than previously assumed.

Genome Analysis and Description of Three Novel Diazotrophs <i>Geomonas</i> Species Isolated From Paddy Soils.

Project description:Five strictly anaerobic strains, designated RG2T, RG3, RG10T, RF4T, and RG29, were isolated from paddy soils in China. Strains RG2T, RF4T, RG10T, RG3, and RG29 grew at temperatures ranging 5-42°C and pH ranging 5.5-8.5. Strains RG2T, RF4T, RG3, and RG29 could tolerate NaCl up to 0-0.7% (w/v) while strain RG10T could tolerate NaCl up to 0-0.8% (w/v). The isolated strains showed the highest 16S rRNA gene sequence similarities to the type strains of Geomonas terrae Red111T and Geomonas paludis Red736T. In phylogenetic (based on 16S rRNA gene sequence) and phylogenomic trees, strains clustered with the members of the genus Geomonas. Menaquinone-8 was the predominant quinone present in all strains. The major fatty acid profiles of all strains were C15:1 ω6c, C16:0, iso-C15:0, and Summed Feature 3. The digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values between the isolated strains and the closely related Geomonas species were lower than the cutoff value (ANI 95-96% and dDDH 70%) for prokaryotic species delineation. Based on physiological, biochemical, and chemotaxonomic properties, strains RG2T, RG10T, and RF4T could easily be differentiated with the members of the genus Geomonas. Additionally, all the isolated strains possessed nifHDK clusters and catalytic compartments of nitrogenase. Based on the above results, the isolated five strains represent three novel species of the genus Geomonas, for which the names Geomonas oryzisoli sp. nov., Geomonas subterranea sp. nov., and Geomonas nitrogeniifigens sp. nov. are proposed. The type strains are RG10T (= GDMCC1.2537T = KCTC 26318T), RG2T (= GDMCC1.2536T = KCTC 25317T), and RF4T (= GDMCC 1.2547T = KCTC 25316T).

A Novel Rapidly Growing <i>Mycobacterium</i> Species Causing an Abdominal Cerebrospinal Fluid Pseudocyst Infection.

Project description:Nontuberculous mycobacteria (NTM) are a rare cause of ventriculoperitoneal shunt infections. We describe the isolation and identification of a novel, rapidly growing, nonpigmented NTM from an abdominal cerebrospinal fluid pseudocyst. The patient presented with fevers, nausea, and abdominal pain and clinically improved after shunt removal. NTM identification was performed by amplicon and whole-genome sequencing.
