Species of Acanthamoeba Volkonsky, 1931 are the commonest among free-living amoebae that are widespread in different water resources but with lacking phylogenetic data. This study aims at detecting molecular prevalence and genetic diversity of Acanthamoeba isolates in Kafrelsheikh Governorate, Egypt. Forty-eight water samples were collected from 12 swimming pools; four samples during each season over one year. Samples were filtered, cultivated on non-nutrient agar plates and examined microscopically. Polymerase chain reaction (PCR) and sequence analysis of positive samples targeting diagnostic fragment 3 (DF3) of the small subunit rRNA...

Folia Parasitologica 69:028 (2022) | DOI: 10.14411/fp.2022.028  

The genus Maxvachonia Chabaud et Brygoo, 1960 (Ascaridomorpha: Cosmocercidae) is a poorly known group of parasitic nematodes. Species of Maxvachonia are native to Madagascar-Australo-Papuan Region, where they are known to parasitise frogs, snakes and skinks. Unfortunately, most of Maxvachonia species have been inadequately described. In the present study, we report the native species Maxvachonia chabaudi Mawson, 1972 from the intestine of the invasive marine toad Rhinella marina (Linnaeus) in Australia for the first time. We speculate that the marine toads infected with M. chabaudi are likely related to their...

Folia Parasitologica 69:027 (2022) | DOI: 10.14411/fp.2022.027  

Species of Blastocystis Alexieff, 1911 are anaerobic intestinal protists found in humans and many kinds of animals that mainly cause diarrhea, abdominal pain and other clinical symptoms. At present, data on the prevalence and subtype diversity of species of Blastocystis in domestic rabbits are very limited. The purpose of this study was to characterise the infection rate and gene subtype distribution of Blastocystis sp. in domestic rabbits in Henan Province, Central China, and provide foundation for prevention and control of the disease caused by Blastocystis sp. in domestic rabbits. DNA was extracted from 286 fresh rabbit...

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...

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...

Does the fish-infecting Trypanosoma micropteri belong to Trypanosoma carassii?

Peng Zhang, Ke Chen, Michaela Svobodová, Ting-Bao Yang, Julius Lukeš, Jinyong Zhang, Zhao-Rong Lun, De-Hua Lai

Folia Parasitologica 69:024 (2022) | DOI: 10.14411/fp.2022.024  

Recently, based on a limited morphological characterisation and partial 18S rRNA gene sequence, Jiang et al. (2019) described Trypanosoma micropteri Jiang, Lu, Du, Wang, Hu, Su et Li, 2019 as a new pathogen of farmed fish. Here we provide evidence based on the expanded sequence dataset, morphology and experimental infections that this trypanosome does not warrant the establishment as a new species, because it is conspecific with the long-term known Trypanosoma carassii Mitrophanow, 1883, a common haemoflagellate parasite of freshwater fish. The former taxon thus becomes a new junior synonym of T. carassii.

Diagnostic accuracy of adjusted low IgG avidity index to predict acute Toxoplasma gondii infection in the first trimester of pregnancy

Miha Skvarč

Folia Parasitologica 69:023 (2022) | DOI: 10.14411/fp.2022.023  

Congenital toxoplasmosis is reportable disease in Europe. To prevent it antibody serological tests were introduced in several European countries as a part of screening programmes. Immunoglobulin G (IgG) avidity index testing is one of these tests for diagnosing acute infection with Toxoplasma gondii (Nicolle et Manceaux, 1908) in pregnant women. However, a low or moderate IgG avidity index can give inconclusive results for predicting woman's status. From June 2012 until the end of 2014, 17,990 women were included in the national screening program to prevent congenital toxoplasmosis. One hundred and twenty-six women were consecutively included...

Comparative exploration of the morphological plasticity of Trichodina centrostrigeata (Peritrichia: Mobilida), ectoparasite from the gills of two tilapia species (Oreochromis niloticus and O. mossambicus) in a global context

Folia Parasitologica 69:022 (2022) | DOI: 10.14411/fp.2022.022  

Trichodina centrostrigeata Basson, Van As et Paperna, 1983 from Oreochromis mossambicus (Peters) and O. niloticus (Linnaeus) from different host populations from Argentina, Mexico and South Africa was reviewed. Although T. centrostrigeata has a distinct denticle structure that makes morphological taxonomic inferences uncomplicated, variation of the denticles within and among individuals and populations were still observed. While traditional taxonomy of mobilines is heavily reliant on morphometrics, and recently even more so on molecular analysis, this paper proposes the use of geometric morphometry, specifically elliptical...

Folia Parasitologica 69:021 (2022) | DOI: 10.14411/fp.2022.021  

Dactylogyrus Diesing, 1850 is the most species-rich genus in Platyhelminthes, with over 900 documented species, that are mostly strictly specific to freshwater cyprinoids. The morphological Dactylogyrus groups afrobarbae-type, carpathicus-type, pseudoanchoratus-type, and varicorhini-type are known to occur in Africa. This study describes a new species of Dactylogyrus of the varicorhini-type from the gills of the endemic smallmouth yellowfish Labeobarbus aeneus (Burchell) from the Vaal River, Free State Province, South Africa. Dactylogyrus matlopong sp. n. is unique among its varicorhini-type congeners mainly by the...

Folia Parasitologica 69:020 (2022) | DOI: 10.14411/fp.2022.020  

Toxoplasma gondii Nicolle et Manceaux, 1909, the etiologic agent of toxoplasmosis, was considered a clonal population with three distinct genetic lineages (I, II and III); however, sequence analysis of different strains has revealed distinct atypical genotypes. Macrophages are essential for immunity against toxoplasmosis and differential cell regulation may affect the course of the disease. In this context, our study aims to investigate the infection by TgChBrUD2, a highly virulent atypical Brazilian strain of T. gondii, on the activation and polarisation of human macrophages. Human macrophage-like cells obtained from THP-1 cells were...

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)...

Folia Parasitologica 69:017 (2022) | DOI: 10.14411/fp.2022.017  

Multivalvulid myxosporeans of the genera Kudoa Meglitsch, 1947 and Unicapsula Davis, 1924 (Cnidaria: Myxozoa) are often the cause of unsightly cyst formation or postmortem myoliquefaction in the trunk muscle of commercial marine fish, which reduces the market value of infected individuals. Twenty species (18 Kudoa spp. and two Unicapsula spp.) have been recorded from carangid fish, although the majority of them, excluding polyxenous species, such as K. amamiensis Egusa et Nakajima, 1980, K. iwatai Egusa et Shiomitsu, 1983, K. nova Naidenova, 1975, K. quadratum (Thélohan, 1895) and K....

Buffaloes represent an important economic resource for several regions of the world including Romania. In the present study, we examined 104 faecal samples collected from 38 buffalo calves (2-11 weeks old) from household rearing systems in Romania for gastrointestinal parasites. All samples were tested using the saturated salt flotation, McMaster and modified Ziehl-Nielsen staining methods. PCR coupled with sequencing isolates were used to identify assemblages of Giardia lamblia (Kunstler, 1882) and species of Cryptosporidium Tyzzer, 1907. Overall, 33 out of 38 examined buffalo calves were infected with different gastrointestinal parasites:...

Role of bank vole (Myodes glareolus) personality on tick burden (Ixodes spp.)

Grégoire Perez

Folia Parasitologica 69:014 (2022) | DOI: 10.14411/fp.2022.014  

Parasitism among individuals in a population often varies more than expected by chance only, leading to parasite aggregation, which is a parameter of paramount importance in parasite population dynamics and particularly in vector-borne epidemiology. However, the origin of this phenomenon is yet not fully elucidated. An increasing body of literature has demonstrated that individuals vary consistently in their behaviour, which is referred to as animal personality. Such behavioural variation could potentially lead to different encounter rates with parasites. To test this hypothesis, the relationship between personality and burden with ticks (Ixodes...

Detection of Dermocystidium anguillae in imported elvers of American eel Anguilla rostrata in China

Dan Li, Pin Nie, Yang Liu

Folia Parasitologica 69:013 (2022) | DOI: 10.14411/fp.2022.013  

In recent years, an emerging dermocystidiosis caused by Dermocystidium anguillae Spangenberg, 1975 has been found to pose a threat to the culture of American eel, Anguilla rostrata (Lesueur), as well as Chinese perch, Siniperca chuatsi (Basilewsky), in China. Dermocystidium anguillae was originally described from European eel, Anguilla anguilla (Linnaeus), and it is thus important to identify the possible source of this pathogen. In the present study, we compared D. anguillae from European eels cultured in China with those from American eels. Molecular analysis showed that the SSU rDNA of D. anguillae...

Molecular evidence suggests the occurrence of Entamoeba moshkovskii in pigs with zoonotic potential from eastern India

Folia Parasitologica 69:012 (2022) | DOI: 10.14411/fp.2022.012  

Entamoeba moshkovskii Tshalaia, 1941 is prevalent in developing countries and it is considered to be primarily a free-living amoeba, which is morphologically indistinguishable, but biochemically and genetically different from the human infecting, pathogenic Entamoeba histolytica Schaudinn, 1903. The pathogenic potential of this organism is still under discussion. Entamoeba moshkovskii in human stool samples has been reported in different countries such as the United States, Italy, Australia, Iran, Turkey, Bangladesh, India (Pondicherry), Indonesia, Colombia, Malaysia, Tunisia, Tanzania and Brazil, but no data are available about...

Janine N. Caira, K. Jensen

Folia Parasitologica 69:010 (2022) | DOI: 10.14411/fp.2022.010  

In an effort to expand knowledge of Clade 3-one of the ten clades that compose the non-monophyletic order 'Tetraphyllidea' all current members of which parasitise orectolobiform sharks-we targeted species of orectolobiform sharks that had not previously been examined for 'tetraphyllidean' cestodes. That work led to the discovery of three new species off Australia and Taiwan. Ambitalveolus gen. n. was erected to accommodate these species. Ambitalveolus costelloae gen. n. et sp. n., Ambitalveolus kempi sp. n., and Ambitalveolus penghuensis sp. n. differ from one another in scolex size, genital pore position, and number of...

Folia Parasitologica 69:009 (2022) | DOI: 10.14411/fp.2022.009  

An outbreak of trichinellosis occurred in Stari Banovci, a settlement in the municipality of Stara Pazova, Srem, Republic of Serbia, in March-April 2019. A total of 28 persons were exposed and trichinellosis was confirmed in 24 of them. This outbreak involved members of eight families, their relatives and friends. The infection, due to Trichinella spiralis (Owen, 1835), was associated with consumption of pork sausages procured in a local butcher's shop. The trace-back study revealed that the meat originated from swine that was raised on a small farm belonging to the owner of the shop, who did not have permission from the Veterinary Directorate...

Folia Parasitologica 69:008 (2022) | DOI: 10.14411/fp.2022.008  

Toxoplasmosis is one of the world's most prevalent zoonoses. The causative agent, Toxoplasma gondii (Nicolle et Manceaux, 1908) is a facultative heteroxenic, polyxenic apicomplexan protist. There are several potential pathways of transmission within and between host species. Most infections with T. gondii result from close contact with pets/cats, ingestion of tissue cysts in undercooked meat of infected animals, and oocysts from food or water contaminated by feline faeces. Recently, epidemiological studies have shown that T. gondii infection plays a prominent role in the pathogenesis of several psychiatric disorders. This report...

Further data on the distribution of Dirofilaria spp. in the Czech Republic in dogs

Jana Juránková, Barbora Šenkyříková Mitková, Marcela Novotná, Lada Hofmannová, Barbora Červená, Dwight D. Bowman, David Modrý

Folia Parasitologica 69:007 (2022) | DOI: 10.14411/fp.2022.007  

Based on previously published data, the Czech Republic is regarded an endemic country of the onchocercid nematodes Dirofilaria immitis (Leidy, 1856) and Dirofilaria repens Railliet et Henry, 1911. Nevertheless, while cases of D. repens are commonly reported from dogs in South Moravia, no recent records of D. immitis are available. Therefore, the present study was performed to clarify the occurrence of both species of Dirofilaria Railliet et Henry, 1910. Blood samples of 551 dogs sampled during 2015 and 2016 were analysed microscopically for presence of microfilariae and blood sera were examined by IDEXX SNAP®...

Intraspecific morphological variation in myxosporeans: high pleomorphic myxospores in the same plasmodium of Myxobolus drjagini (Akhmerov, 1954)

Yang Liu, Jiayun Yao, Xin Yao, Kaijie Zhang, Qingyong Wang, Xiaoyi Pan, Jinyong Zhang

Folia Parasitologica 69:006 (2022) | DOI: 10.14411/fp.2022.006  

The taxonomy of myxosporeans was traditionally dependent solely upon the spore morphological and morphometric data. Intensive reports of intraspecific morphological variation, however, are increasingly challenging the taxonomic approaches for myxosporeans. In the present work, the morphological pleomorphism of myxospores of Myxobolus drjagini (Akhmerov, 1954) was observed. More interestingly, all of these pleomorphic myxospores occurred in the same plasmodium of M. drjagini, which refutes the previous hypothesis that morphological variation of M. drjagini was derived from its responses to differences in nutrition and immunological...

Folia Parasitologica 69:005 (2022) | DOI: 10.14411/fp.2022.005  

Rhipicephalus camicasi Morel, Mouchet et Rodhain, 1976 is thought to be distributed across Africa, Arabian Peninsula and the Mediterranean region. It belongs to the Rhipicephalus sanguineus (Latreille, 1806) species complex. Mitochondrial genome sequences are becoming frequently used for the identification and differentiation of tick species. In the present study, the entire mitochondrial genome of R. cf. camicasi (~15 kb) collected from a camel in Saudi Arabia was sequenced and compared with mitogenomes of two species of Rhipicephalus Koch, 1844. The mitochondrial genome is 87.8% and 91.7% identical...

An unexpected tenant: contamination in a Physeter catodon (Physeteridae, Artiodactyla) genome indicates undescribed species of Sarcocystis Lankester, 1882 (Sarcocystidae, Eucoccidiorida) in the marine environment

Joaquim Filipe Faria, David James Harris

Folia Parasitologica 69:004 (2022) | DOI: 10.14411/fp.2022.004  

Data mining animal of genomes has been used before to identify endoparasites, and may be a particularly useful tool to surpass some difficulties faced by studies in the marine environment. We detected a species of Sarcocystis Lankester, 1882, contamination in the sperm whale (Physeter catodon Linnaeus) reference genome available in the GenBank database. We identified and extracted multiple gene fragments and placed the sequences in a phylogenetic framework. Our results indicate that the sequences of Sarcocystis sp. found in the genome do not correspond to any currently described species, despite a few other similar sequences having...

Folia Parasitologica 69:003 (2022) | DOI: 10.14411/fp.2022.003  

In the present study, we have investigated the role of antimalarial drug halofantrine (HF) in inducing the sterile protection against challenges with sporozoites of the live infectious Plasmodium yoelii (Killick-Kendrick, 1967) in Swiss mice malaria model. We observed that during the first to third sequential sporozoite inoculation cycles, blood-stage patency remains the same in the control and chemoprophylaxis under HF drug cover (CPS-HF) groups. However, a delayed blood-stage infection was observed during the fourth and fifth sporozoite challenges and complete sterile protection was produced following the sixth sporozoite challenge in CPS-HF...
