Alveolar echinococcosis is a severe chronic helminthic disease that mimics slow-growing liver cancer. The immune evasion strategy of Echinococcus multilocularis Leuckart, 1863 remains poorly understood. The aim of this study was to investigate in vitro the impact of E. multilocularis vesicular fluid (Em-VF) on peripheral blood mononuclear cells (PBMC) and on natural killer (NK) cells. PBMC and NK cells were exposed to Em-VF (1 µg/ml) during six days. The effect of Em-VF was assessed on CD69, viability and proliferation, and on and transforming growth factor β (TGF-β), interferon γ (IFN-γ),...

Martina Orosová, Marta Špakulová

Folia Parasitologica 65:001 (2018) | DOI: 10.14411/fp.2018.001  

The history and value of cytogenetic features for addressing questions of the evolution and systematics of tapeworms (Cestoda) are briefly reviewed along with instructions for collecting karyological data. As a supplement to worm morphology, chromosome number and morphology have been helpful in determining the systematic status of some genera in the Diphyllobothriidae and species in the Bothriocephallidea. In addition, many new techniques for chromosome analysis have been recently applied in morphological and molecular studies of invertebrates, including tapeworms. Methods of molecular karyology, fluorescence in situ hybridisation, and chromosomal...

Courtney Antonia Cook, Edward Charles Netherlands, Johann van As, Nico Jacobus Smit

Folia Parasitologica 65:004 (2018) | DOI: 10.14411/fp.2018.004  

To date, only a few species of Hepatozoon Miller, 1908 have been described from amphibians and reptiles of South Africa, including two species from anuran hosts, three from saurians, one from chelonians, and two from ophidians. Hepatozoon bitis (Fantham, 1925) and Hepatozoon refringens (Sambon et Seligmann, 1907), parasitising Bitis arientans (Merrem) and Pseudoaspis cana (Linnaeus), respectively, were described in the early 1900s and since then there have been no further species of Hepatozoon described from snakes in South Africa. Blood smears, used in peripheral blood haemogregarine stage morphometrics, and...

Ornampai Japa, Serge Morand, Anamika Karnchanabanthoeng, Kittipong Chaisiri, Alexis Ribas

Folia Parasitologica 65:018 (2018) | DOI: 10.14411/fp.2018.018  

The presence of Neospora caninum Dubey, Carpenter, Speer, Topper et Uggla, 1988 in small mammals (i.e. murid rodents, Erinaceomorpha, Eulipotyphla and Scadentia) was explored for first time in South-East Asia. A total of 192 individuals from six localities across Thailand were analysed. A general prevalence of N. caninum of 22% was observed, with some variation among localities (5-36%). Four main types of habitat were included and rodents trapped in dry-land habitat (17 positive among 41 individuals) were more likely to be infected with N. caninum than those from other habitats (forest, rain-fed land and settlement). Rodent species...

First molecular assessment of the interrelationships of cladorchiid digeneans (Digenea: Paramphistomoidea), parasites of Neotropical fishes, including descriptions of three new species and new host and geographical records

Camila Pantoja, Tomáš Scholz, José Luis Luque, Arlene Jones

Folia Parasitologica 66:011 (2019) | DOI: 10.14411/fp.2019.011  

The first molecular assessment of phylogenetic relationships of cladorchiid digeneans (superfamily Paramphistomoidea Fischoeder, 1901) from freshwater fishes based on 28S rDNA, ITS2 and cox1 sequences reveals the subfamilies Dadayiinae Fukui, 1929 and Kalitrematinae Travassos, 1933 as non-monophyletic, whereas Dadaytrema Travassos, 1931 represented by three species is monophyletic. Fourteen species of cladorchiids were found in characiform, perciform and siluriform fishes in the Neotropical Region (Brazil and Peru), with numerous new host and geographical records. The first scanning electron micrographs of seven species are presented....

Redescription and neotype designation for the poorly known fish parasitic cymothoid Joryma brachysoma (Pillai, 1964) (Crustacea: Isopoda) from India

Panakkool Thamban Aneesh, Ameri Kottarathil Helna, Appukuttannair Biju Kumar

Folia Parasitologica 66:014 (2019) | DOI: 10.14411/fp.2019.014  

A neotype is designated for Joryma brachysoma (Pillai, 1964). The general morphology and appendages of the female and male stages are illustrated and re-described based on the neotype and several additional fresh specimens collected from the type host Pellona brachysoma Bleeker (=Sardinella brachysoma Bleeker) from nearby the type locality. The present redescription and neotype designation further resolves the taxonomic ambiguity regarding the species identification and conserves the name of J. brachysoma.

Krzysztof Czyzewski, Jowita Fraczkiewicz, Malgorzata Salamonowicz, Anna Pieczonka, Olga Zajac-Spychala, Agnieszka Zaucha-Prazmo, Jolanta Gozdzik, Jan Styczynski

Folia Parasitologica 66:019 (2019) | DOI: 10.14411/fp.2019.019  

Toxoplasmosis is a potentially fatal complication after hematopoietic cell transplantation (HCT). Pre-transplant seropositivity of graft recipient to Toxoplasma gondii (Nicolle et Manceaux, 1908) is an important factor for disease reactivation after HCT. As toxoplasmosis epidemiology varies all over the world, we performed a Polish nationwide retrospective cohort study to determine the seroprevalence of toxoplasmosis in donors and pediatric allogeneic and autologous HCT recipients and the incidence of clinically evident toxoplasmosis in this patient group. Polish adult donors had higher anti-T. gondii seroprevalence than Polish pediatric...

Cannibalism in mosquito larvae during microbial larvicide potency tests

Igor Uspensky, Sergei Braun^*

Folia Parasitologica 67:005 (2020) | DOI: 10.14411/fp.2020.005  

We observed instances of cannibalism (intraspecific predation) among intra-instar larvae of Culex pipiens Linnaeus, 1758 while performing a bioassay of Lysinibacillus sphaericus (formerly named Bacillus sphaericus) larvicide, when the larvae were exposed to the larvicide for 48 h in the absence of food. Larvae without symptoms of poisoning attacked and devoured those visibly affected. Cannibalism was more prevalent in 1^st-2^nd instar larvae than in 3^rd-4^th instar. This phenomenon should be taken into account when interpreting the results of larvicide bioassays, especially when the exposure...

Molecular identification of morphologically similar microcercous cercariae of two trematode families, Paragonimidae and Troglotrematidae, concurrently found in the same snail species of the subfamily Triculinae

Pham Ngoc Doanh, Hoang Van Hien, Bui Thi Dung

Folia Parasitologica 67:008 (2020) | DOI: 10.14411/fp.2020.008  

Microcercous cercariae possess a very short tail and are produced by digenean species of several families including medically important species, such as members of the genera Paragonimus Braun, 1899, Nanophyetus Chapin, 1927 and Troglotrema Odhner, 1914. During our survey of cercariae of Paragonimus spp. in Vietnam, we found microcercous cercariae from ten (0.29%) out of 3,400 snails of Triculinae gen. sp. 2. They were morphologically and molecularly analysed for species identification. The molecular analysis, based on ITS2 sequences, revealed two distinct species: four specimens were identical to Paragonimus proliferus...

Morgane A. Henry, Fotini Kokou, Oswaldo Palenzuela, George Pyrenis, George Rigos

Folia Parasitologica 67:024 (2020) | DOI: 10.14411/fp.2020.024  

An infection model for sharpsnout seabream Diplodus puntazzo (Walbaum) challenged with the myxosporean Enteromyxum leei (Diamant, Lom et Dyková, 1994), resembling the natural infection conditions, was used to evaluate the antiparasitic efficacy of a functional diet. Fish of an average weight of 12.5 ± 1.2 g were delivered either a functional (included as feed supplement at 0.3% levels) or a control extruded diet. After four weeks of administration of the experimental diets, fish were challenged with the parasites (cohabitation with infected donors; donor: recipient ratio 1 : 1). The experiment...

Xin Zhuo Zhang, Xiang Yuan Sun, Ying Bai, Wen Wen Yue, Xin Yue, Yan Yan Song, Jing Cui, Zhong Quan Wang

Folia Parasitologica 67:027 (2020) | DOI: 10.14411/fp.2020.027  

The elastase, which belongs to the serine protease family, hydrolyses various proteins and may be involved in the parasite invasion. In this study, complete sequence of elastase-1 (TsE) the nematode Trichinella spiralis (Owen, 1835) was cloned into the plasmid pcDNA3.1 as TsE DNA vaccine. After intramuscular vaccination, serum anti-Trichinella antibodies (IgG and subclass IgG1/IgG2a, and IgA), total and specific intestinal mucosal sIgA in mice vaccinated with pcDNA3.1/TsE were measured by ELISA. The results showed that vaccination with pcDNA3.1/TsE induced a systemic humoral immune response (high levels of serum IgG and subclass IgG1/IgG2a...

Šárka Kaňková, Marie Bičíková, Ludmila Máčová, Jana Hlaváčová, Kateřina Sýkorová, Dobroslava Jandová, Jaroslav Flegr

Folia Parasitologica 68:005 (2021) | DOI: 10.14411/fp.2021.005  

Numerous recent studies show that vitamin D deficiency potentiates various chronic physical and psychiatric disorders and diseases. It has been shown that a similar range of disorders is also associated with latent infection with Toxoplasma gondii (Nicolle et Manceaux, 1908). For instance, among cancer, diabetes and schizophrenia patients, we find a higher prevalence of both toxoplasmosis and vitamin D deficiency. Theoretically, therefore, vitamin D deficiency could be the missing link between toxoplasmosis and these disorders. We tested this hypothesis by searching for decreased vitamin D levels in the serum of subjects infected with T....

Anja Vermaak, Nico J. Smit, Olena Kudlai

Folia Parasitologica 68:007 (2021) | DOI: 10.14411/fp.2021.007  

South African clinids are a major component of the temperate intertidal regions that are also known to participate in life cycles and transmission of several groups of parasites. However, the knowledge of trematode diversity of these fishes is incomplete. In this study, two species of Clinus Cuvier, the super klipfish Clinus superciliosus (Linnaeus) and the bluntnose klipfish Clinus cottoides Valenciennes, were collected from six localities along the South African coast and examined for the presence of trematodes. Metacercariae of Cardiocephaloides Sudarikov, 1959 were found in the eye vitreous humour and brain of C....

Folia Parasitologica 68:026 (2021) | DOI: 10.14411/fp.2021.026  

Apoptosis plays crucial role in the pathogenesis of toxoplasmosis, as it limits further development of the disease. The current study aimed to investigate the effects of different concentrations of soluble total antigen (STAg) of Toxoplasma gondii (Nicolle et Manceaux, 1908) on the apoptotic and anti-apoptotic pathways. PMA-activated THP-1 cell line was sensed by T. gondii STAg and the expression patterns of caspase-3, -7, -8, -9, Bax, Bcl-2, and Mcl-1 genes were evaluated. The results showed statistically significant concentration-dependent overexpression of both Bcl-2 (P-value < 0.0001) and Mcl-1 (P-value = 0.0147)....

Folia Parasitologica 69:019 (2022) | DOI: 10.14411/fp.2022.019  

A three-year-old male South China tiger died in the tiger enclosure of the China Tiger Park in the Meihua Mountains on December 2018 after being bitten by a tick. This tiger presented clinical symptoms like whole-body severe jaundice, hepatosplenomegaly, kidney, and lymph node hemorrhages. The Colpodella sp.-specific 18S rRNA gene was detected using nested PCR. Interestingly, the DNA isolated from the blood of the tiger was found to be 100% similar to that of the tick by NCBI BLAST analysis. However, the DNA fragments isolated from the tiger's blood were 90.1% similar to the Colpodella sp. strain human erythrocyte parasite (HEP, MH208621)...

Salmincola markewitschi or S. carpionis (Copepoda: Lernaeopodidae)? A requirement for taxonomic revision due to their high morphological variations

Ryota Hasegawa, Hirotaka Katahira, Itsuro Koizumi

Folia Parasitologica 69:025 (2022) | DOI: 10.14411/fp.2022.025  

Salmincola markewitschi Shedko et Shedko, 2002 (Copepoda: Lernaeopodidae) is an ectoparasitic copepod mainly infecting the buccal cavities of white-spotted charr Salvelinus leucomaenis (Pallas) (Salmonidae). This species has only been recorded from Northeast Asia, where a morphologically similar congener Salmincola carpionis (Krøyer, 1837) is also distributed, using the same host species. These copepods are hard to distinguish from each other because of their similarities. We thus examined the newly collected specimens morphologically and genetically from five populations of white-spotted charr in Japan. Most of the specimens...

Confocal laser scanning microscopy (CLSM) as a new tool for morphological characterisation of both newly collected and museum voucher specimens of the Trypanorhyncha Diesing, 1863 (Platyhelminthes: Cestoda)

Xaver Neitemeier-Duventester, Andreas Bick, Stefan Theisen, Harry W. Palm

Folia Parasitologica 69:026 (2022) | DOI: 10.14411/fp.2022.026  

Taxonomic issues within Trypanorhyncha, e.g., the inaccurate light microscopic visualisation of the hook patterns, are solvable by confocal laser scanning microscopy (CLSM). We applied CLSM imaging to study Trygonicola macropora (Shipley et Hornell, 1906) and Dollfusiella michiae (Southwell, 1929) from Neotrygon caeruliopunctata Last, White et Séret from Bali, Indonesia. To illustrate the strength and limitations of CLSM, images of Otobothrium cysticum (Mayer, 1842) and Symbothriorhynchus tigaminacantha Palm, 2004, both permanent mounts from a collection, were also processed. The CLSM created image stacks of...

First report of Spirometra (Eucestoda; Diphyllobothriidae) naturally occurring in a fish host

Renzo Vettorazzi, Walter Norbis, Sergio R. Martorelli, Graciela García, Néstor Ríos

Folia Parasitologica 70:008 (2023) | DOI: 10.14411/fp.2023.008  

Spirometra Faust, Campbell et Kellogg, 1929 is a genus of cestodes belonging to the family Diphyllobothriidae. To date, amphibians, reptiles, and mammals are known second intermediate hosts of these parasites; humans can also be infected (the zoonotic disease is known as sparganosis or spirometrosis). Although the number of phylogenetic studies on Spirometra spp. has increased worldwide in recent years, there are few in South America. Specifically in Uruguay, molecular studies have shown that tapeworms of S. decipiens (Diesing, 1850) complexes 1 and 2 are present in this country. In this study, we characterised the larvae of Spirometra...

Molecular characterisation of three species of Coitocaecum (Digenea: Opecoelidae) infecting Clinus superciliosus (Clinidae) in South Africa, with description of Coitocaecum brayi sp. n.

Anja Vermaak, Nico J. Smit, Olena Kudlai

Folia Parasitologica 70:015 (2023) | DOI: 10.14411/fp.2023.015  

The genus Coitocaecum Nicoll, 1915 is part of the most speciose digenean family, the Opecoelidae Ozaki, 1925, which is found globally in both freshwater and marine fishes. Fifteen opecoelid species have been reported from marine fishes in South Africa, yet only one species of Coitocaecum has been described from this region: Coitocaecum capense Bray, 1987. During an explorative study of the digeneans of the endemic, intertidal fish Clinus superciliosus (Linnaeus) from the Saldanha Bay area, Cape Town harbour, Hermanus, the Tsitsikamma section of the Garden Route National Park and Chintsa East in South Africa, a total...

Folia Parasitologica 71:008 (2024) | DOI: 10.14411/fp.2024.008  

Susceptibility to COVID-19, the most devastating global pandemic, appears to vary widely across different population groups. Exposure to toxoplasmosis has been proposed as a theory to explain the diversity of these populations. The aim of the present study was to investigate the possible association between latent toxoplasmosis and COVID-19 and its probable correlation with markers of oxidative stress, C-reactive protein (CRP) and ferritin. In a case-control study, blood samples were collected from 91 confirmed (48 non-pneumonic; NP, and 43 pneumonic; P) COVID-19 patients and 45 healthy controls. All participants were tested for IgG anti-Toxoplasma...

Martina Lisnerová, Pavla Bartošová-Sojková, Monika Bürgerová, Ivan Fiala

Folia Parasitologica 71:015 (2024) | DOI: 10.14411/fp.2024.015  

Myxozoans are microscopical parasites widely distributed in fish, with over 2,600 described species, but their actual diversity is still underestimated. Among salmonids, more than 70 myxozoan species have been identified. This study focuses on species of Chloromyxum Mingazzini, 1890 that infect salmonid kidneys, particularly C. majori Yasutake et Wood, 1957 and C. schurovi Shulman et Ieshko, 2003. Despite their similar spore morphology, they exhibit distinct host preferences, tissue affinities and geographical distributions. Chloromyxum schurovi predominantly infects the renal tubules of Salmo salar Linnaues and S....
