Project description:We found Rickettsia raoultii DNA in 2 out of 32 (6.25 %) Haemaphysalis erinacei ticks. Result showed that the sequences of five genes (17-kDa, gltA, ompA, rrs, and ompB) were 100 % identity with that of R. Raoultii in GenBank. This study is the first report on the presence of R. raoultii in H. erinacei from wild marbled polecat, Vormela peregusna. Our findings suggest that H. erinacei parasitizing wild marbled polecat may serve as reservoir and carriers for R. raoultii in areas around the China-Kazakhstan border. The transmission of tick-borne diseases originated from wildlife should not be underestimated in border region.

Project description:BackgroundAlthough spargana, which are the plerocercoids of Spirometra erinacei, are of biological and clinical importance, expressed sequence tags (ESTs) from this parasite have not been explored. To understand molecular and biological features of this parasite, sparganum ESTs were examined by large-scale EST sequencing and multiple bioinformatics tools.MethodsTotal RNA was isolated from spargana and then ESTs were generated, assembled and sequenced. Many biological aspects of spargana were investigated using multi-step bioinformatics tools.ResultsA total of 5,634 ESTs were collected from spargana. After clustering and assembly, the functions of 1,794 Sparganum Assembled ESTs (SpAEs) including 934 contigs and 860 singletons were analyzed. A total of 1,351 (75%) SpAEs were annotated using a hybrid of BLASTX and InterProScan. Of these genes, 1,041 (58%) SpAEs had high similarity to tapeworms. In the context of the biology of sparganum, our analyses reveal: (i) a highly expressed fibronectin 1, a ubiquitous and abundant glycoprotein; (ii) up-regulation of enzymes related with glycolysis pathway; (iii) most frequent domains of protein kinase and RNA recognition motif domain; (iv) a set of helminth-parasitic and spargana-specific genes that may offer a number of antigen candidates.ConclusionsOur transcriptomic analysis of S. erinacei spargana demonstrates biological aspects of a parasite that invades and travels through subcutaneous tissue in intermediate hosts. Future studies should include comparative analyses using combinations of transcriptome and proteome data collected from the entire life cycle of S. erinacei.

Project description:Zoophilic fungal infections are a prevalent disease in tropical countries and clinicians must consider them in the differential diagnosis of pruritic skin lesions. We report a clinical case of Trichophyton erinacei skin infection after recreational exposure to an Asian Elephant. As far as we were able to search the literature, it is the first case described after contact with elephants.

Project description:We postulated that apolysis was processed in accordance with apoptotic changes occurring in a cestode, Spirometra erinacei (Pseudophyllidea). We cloned the novel putative apoptosis-associated gene from S. erinacei via screening of a S. erinacei cDNA library with a ced-3 gene (activator of apoptosis) probe from Caenorhabditis elegans. We identified a 261-bp cDNA sequence, which encodes for an 86-amino acid protein. The cloned gene expression was observed in the neck and gravid proglottids via Northern blotting, using cloned cDNA inserts as probes, but the clone was not expressed in any of other tissues. We suggest that this gene may be involved in the apolysis of S. erinacei during normal tissue development and differentiation in cestode parasites.

Project description:The mature domain of a cysteine protease of Spirometra erinacei plerocercoid larva (i.e., sparganum) was expressed in Escherichia coli, and its value as an antigen for the serodiagnosis of sparganosis was investigated. The recombinant protein (rSepCp-1) has the molecular weight of 23.4 kDa, and strongly reacted with the sparganum positive human or mice sera but not with negative sera by immunoblotting. ELISA with rSepCp-1 protein or sparganum crude antigen (SeC) was evaluated for the serodiagnosis of sparganosis using patient's sera. The sensitivity and specificity of ELISA using rSepCp-1 protein were 95.0% (19/20) and 99.1% (111/112), respectively. In contrast, the sensitivity and specificity of ELISA with SeC were 100% (20/20) and 96.4% (108/112), respectively. Moreover, in experimentally infected mice, the sensitivity and specificity of both ELISA assays were 100% for the detection of anti-sparganum IgG. It is suggested that the rSepCp-1 protein-based ELISA could provide a highly sensitive and specific assay for the diagnosis of sparganosis.

Project description:BackgroundHaemaphysalis erinacei is one of the few ixodid tick species for which valid names of subspecies exist. Despite their disputed taxonomic status in the literature, these subspecies have not yet been compared with molecular methods. The aim of the present study was to investigate the phylogenetic relationships of H. erinacei subspecies, in the context of the first finding of this tick species in Romania.ResultsAfter morphological identification, DNA was extracted from five adults of H. e. taurica (from Romania and Turkey), four adults of H. e. erinacei (from Italy) and 17 adults of H. e. turanica (from China). From these samples fragments of the cytochrome c oxidase subunit 1 (cox1) and 16S rRNA genes were amplified via PCR and sequenced. Results showed that cox1 and 16S rRNA gene sequence divergences between H. e. taurica from Romania and H. e. erinacei from Italy were below 2%. However, the sequence divergences between H. e. taurica from Romania and H. e. turanica from China were high (up to 7.3% difference for the 16S rRNA gene), exceeding the reported level of sequence divergence between closely related tick species. At the same time, two adults of H. e. taurica from Turkey had higher 16S rRNA gene similarity to H. e. turanica from China (up to 97.5%) than to H. e. taurica from Romania (96.3%), but phylogenetically clustered more closely to H. e. taurica than to H. e. turanica.ConclusionsThis is the first finding of H. erinacei in Romania, and the first (although preliminary) phylogenetic comparison of H. erinacei subspecies. Phylogenetic analyses did not support that the three H. erinacei subspecies evaluated here are of equal taxonomic rank, because the genetic divergence between H. e. turanica from China and H. e. taurica from Romania exceeded the usual level of sequence divergence between closely related tick species, suggesting that they might represent different species. Therefore, the taxonomic status of the subspecies of H. erinacei needs to be revised based on a larger number of specimens collected throughout its geographical range.
