Here we demonstrate the transient transfection of C. baileyi. We describe the transfection of this apicomplexan parasite and the cultivation in ovo. The functionality of heterologous sequences in C. baileyi was demonstrated by the expression and detection of the mCherry protein in ovo. The mCherry protein was expressed in parasitic stages up to the oocyst stage under the control of the heterologous promoter region of the C. parvum actin gene.

MicroRNAs (miRNAs) are important gene regulators that are key players in animal development and diseases. They are excreted in extracellular vesicles and because they were shown to be taken up by host cells they have been proposed as mediators of parasite-host communication, and potential biomarkers for the detection of parasitic infections from host blood. Consequently, it is crucial to precisely know the miRNA complements of medically important agents such as the liver flukes of the Opisthorchiidae. Using publicly available and new datasets we curated and reannotated the surprisingly small and variable miRNA complements previously described for Opisthorchis viverrini, O...

The present study is an integrative taxonomic analysis of Pavanelliella spp. (Monogenoidea, Dactylogyridae), and describes a new species from the nasal cavities of the Amazonian pimelodid catfish Brachyplatystoma rousseauxii (Siluriformes Pimelodidae) from the Tapajós River (Amazon Basin, Pará state, Brazil). Pavanelliella jarii sp. n. is characterized by the presence of 3-4 rings in the male copulatory organ, the absence of rings around the vaginal atrium and by its sinuous vaginal canal, which sometimes forms 0...

The increasing resistance of malaria to drugs raise the need to new antimalarial agents. Antiplasmodial herbs and their active compounds are the most promising source the new antimalarial agents. This study aimed to identify the medicinal plants with very good in vitro antiplasmodial activities, with half-maximal inhibitory concentration (IC50)≤1μg/ml, and to determine trends in the process of screening their antiplasmodial activities. A total of 58 reports published in the English language were retrieved from the bibliographical databases...

Acute postinfectious glomerulonephritis (GN) secondary to scabies were mainly documented as early as in 1980s, and in all these published cases no histopathological evidence of renal biopsy were reported regarding scabies and renal damage. The delay in scabies treatment can result in a greater risk of secondary bacterial infections that can become invasive and/or lead to severe post-infective complications such as post-streptococcal glomerulonephritis. In diagnostic procedures, the clinical presentation of scabies is often atypical especially in elderly people patients...

Leeches belonging to the genus Ozobranchus are ectoparasitic on sea and freshwater turtles. The freshwater species O. jantseanus has been recorded from China and Japan. Ozobranchus jantseanus inhabiting Japan is considered to be a non-indigenous species, because their primary host, the Reeves' pond turtle, Mauremys reevesii, is thought to have been introduced in the last few centuries from adjacent Asian countries. To assess whether the Japanese populations of O. jantseanus were likely to have been introduced, their genetic diversity was investigated using mitochondrial cytochrome c oxidase subunit I sequences...

A marked reduction has been achieved in the incidence and clinical course of toxoplasmic encephalitis after the introduction of protease inhibitors within the treatment regimen of HIV (HIV-PIs). This work was undertaken to study for the first time, the efficacy of HIV-PIs, lopinavir/ritonavir (L/R), as a therapeutic agent in acute experimental toxoplasmosis. Lopinavir/ritonavir (L/R) were used in the same ratio present in aluvia, a known HIV-PIs drug used in the developing countries in the treatment regimens of AID's patient...

Mucin is a major component of mucus in gastrointestinal mucosa. Increase of specific sialomucins having Sd(a) blood group antigen, NeuAcα2-3(GalNAcβ1-4)Galβ1-4GlcNAcβ-, is considered to be associated with expulsion of the parasitic intestinal nematode Nippostrongylus brasiliensis. In this study, we examined the relationship between interleukin (IL)-13 pathway and expression of Sd(a)-sialomucins in small intestinal mucosa with N. brasiliensis infection. Nematode infection induced marked increases in small intestinal mucins that reacted with anti-Sd(a) antibody in wild type (wt) mice...

Drugs containing the1,4-dihydropyridine (DHP) core have recently attracted attention concerning their antiparasitic effect against various species of Leishmania and Trypanosoma. This approach named drugs repositioning led to interesting results, which have prompted us to prepare 21 DHP's analogues. The 1,4-DHP scaffold was decorated with different function groups at tree points including the nitrogen atom (NH and N-phenyl), the aryl group attached to C-4 (various substituted aryl residues) and the carbon atoms 2 and 6 (bearing Ph or Me groups)...

The rare myzostomid genus Asteriomyzostomum Jägersten, 1940 consists of two species, both parasitizing sea stars. The phylogenetic position of this genus among Myzostomida has not been previously shown using molecular data. In this study, three species of Asteriomyzostomum were collected from the Kumano Sea, Japan, and are described as A. jinshou sp. nov., A. monroeae sp. nov., and A. hercules sp. nov. Additional specimens of the genus Asteromyzostomum were also collected from the Kumano Sea and briefly reported as Asteromyzostomum sp...

Osteo-cutaneous form is a rare presentation of acanthamoebiasis. We present the first such case from India in an apparently healthy male who developed cutaneous lesion with bone involvement after traumatic inoculation of Acanthamoeba cysts. The diagnosis was established by routine microbiological techniques and confirmed by 18SrRNA gene sequencing. Aggressive therapy with terbinafine, chlorhexidine, rifampicin and co-trimoxazole was successful in clearing the lesion and preventing encephalitis.

Nematodes belonging to the genus Anisakis are important parasites due to their abundance in seafood and health impacts on humans. In the present study Anisakis larvae were found in a number of uncommon hosts including the Grey petrel, Procellaria cinerea, the Little penguin, Eudyptula minor, Blue-lipped sea krait, Laticauda laticaudata and Spinner shark, Carcharhinus brevipinna. Morphological examination showed nematodes in these animals are Anisakis larval type I. Genetic characterisation suggested that the larva from one Grey petrel was Anisakis berlandi, whereas the other larvae from the second Grey petrel and from the little penguin were Anisakis pegreffii...

The examination of the two batoid species, Pastinachus sephen (Forsskål) and Himantura gerrardi (Gray), resulted in a morphologic identification of the five eutetrarhynchid species, namely Parachristianella indonesiensis Palm, 2004 reported for the first time from Himantura gerrardi, Pa. monomegacantha Kruse, 1959, Prochristianella clarkeae Beveridge, 1990, Pr. butlerae Beveridge, 1990 and Dollfusiella spinulifera (Beveridge et Jones, 2000). By sequencing the partial 28S rDNA and calculating the genetic distances between the morphologically identified specimens from the Persian Gulf and their allopatric morphological conspecifics as well as using a phylogeny, the specimens of the Persian Gulf were considered as the allopatric conspecifics of Parachristianella indonesiensis, Pa...

Specimens of Syndesmis aethopharynx Westervelt & Kozloff, 1990 (Umagillidae, Rhabdocoela, Platyhelminthes) were collected from the intestine of several specimens of the sea urchin Paracentrotus lividus (Lamarck ) Hansson, 2001 at the Greek coast. This represents the first report of a species of Syndesmis from Greece. Our study has revealed several previously-unreported morphological details and intraspecific variation, which are added to the species description. The position of S. aethopharynx within Umagillidae is confirmed for the first time through molecular data (based on nuclear 18S rDNA), using both Bayesian and maximum likelihood analyses...

Host cell invasion is the only step where Babesia parasites are extracellular, and their survival is menaced during this step. Therefore, interfering with this critical stage is a target for an anti-Babesia intervention strategy. In this regard, recombinant protein encoding Babesia divergens Erythrocyte Binding Protein (BdEBP) was produced in Escherichia coli in the current study, and its antiserum was prepared in mice for further molecular characterization. Western blotting and indirect fluorescent antibody test (IFAT) revealed the specific reaction of the anti-rBdEBP serum with a corresponding authentic protein of B...

The Pegosomum Ratz, 1903 are digenean parasites of piscivorous birds. They exhibit few morphological autapomorphies and some of their identification features (number of collar spines) can be altered before or during fixation. Several re-classifications within the genus were suggested, but they have never been supported by molecular analyses. We addressed the synonymization of species within Pegosomum asperum/saginatum complex suggested by Dubinin, Dubinina and Saidov. We analyzed one nuclear (ITS2) and two mitochondrial (CO1, ND1) loci of two central European species of Pegosomum, namely Pegosomum asperum (Wright, 1879) Ratz, 1903 and Pegosomum saginatum (Ratz, 1898) Ratz, 1903...

Greece represents an important area for wild birds due to its geographical position and habitat diversity. Although the bird species in Greece are well recorded, the information about the chewing lice that infest them is practically non-existent. Thus, the aim of the present study was to record the species of lice infesting wild birds in northern Greece and furthermore, to associate the infestation prevalence with factors such as the age, sex, migration and social behaviour of the host as well as the time of the year...
