Histochemical differentiation of four species of the genus Trichinella from days 10-40 of their development in muscles of experimentally infected mice.

D Hulínská, B Shaikenov, M Grim

Folia Parasitologica 31[1] 19 (1984)  

Differences in an infection of the muscle caused by larval T. pseudospiralis (from days 10-40 p.i.) and that caused by capsule-forming Trichinella larvae were disclosed with histochemical techniques. These were: An intense reaction of the modified sarcoplasm for neutral mucosubstances, and intense staining of spherical centres of re-differentiation in the sarcoplasm for tyrosine, activity of the acid phosphatase, a negative reaction for SS groups of proteins at the site of location of the parasite owing to the absence of a collagen-like substance deposited by capsule-forming Trichinella species. Alkaline phosphatase activity weak in a sarcoplasm infected...

Characterization and function of the microsporidian polar tube: a review

Elaine M. Keohane, Louis M. Weiss

Folia Parasitologica 45[2] 117-127 (1998)  

Microsporidia are eukaryotic, obligate intracellular organisms defined by their small spores containing a single polar tube that coils around the interior of the spore. After appropriate stimuli the germination of spores occurs. Conditions that promote germination vary widely among species, presumably reflecting the organism's adaptation to their host and external environment as well as preventing accidental discharge in the environment. It appears that calcium may be a key ion in this process. Regardless of the stimuli required for activation, all microsporidia exhibit the same response to the stimuli, that is, increasing the intrasporal osmotic pressure....

Taxonomic problems, seasonality and histopathology of Henneguya creplini (Myxosporea) infection of the pikeperch Stizostedion lucioperca in Lake Balaton

Kálmán Molnár

Folia Parasitologica 45[4] 261-269 (1998)  

Plasmodia of a Henneguya species measuring 70-900 µm and exhibiting season-dependent stages of development were detected throughout a three-year study on gill myxosporosis of Lake Balaton pikeperch (Stizostedion lucioperca (L.)). Sixty-five out of 160 fish (41%) examined in the period of study were infected by the parasite. Infection was the most prevalent (48%) among pikeperch specimens exceeding 40 cm in length. The highest prevalence of infection (58%) was recorded in 1995-1996 while the lowest (30%) in 1996-1997. The youngest plasmodia appeared in April, and started to develop within the capillaries of the secondary lamellae of the gill filaments....

Microhabitats of Pseudodactylogyrus anguillae and P. bini (Monogenea: Dactylogyridae) on the gills of large-size European eel Anguilla anguilla from Lake Gaj, Poland

Ewa Dzika

Folia Parasitologica 46[1] 33-36 (1999)  

A study on the spatial distribution of two congeneric monogenean species Pseudodactylogyrus anguillae Yin et Sproston, 1948 and P. bini Kikuchi, 1929 on the gills of large size European eel Anguilla anguilla (L.) were conducted. Results were analysed with regard to: single-species infection, mixed infection and general occurrence of the parasites in the eel population. Statistical analysis revealed that the distribution of these species on the gill apparatus is fairly similar and the zones in which they occur more numerously coincide to a great extent. However, a number of differences were found. Both the possibility of simultaneous...

On the morphological variability of the attachment organ of Lernaeopodidae (Copepoda: Siphonostomatoida)

Ouafae Benkirane, Françoise Coste, André Raibaut

Folia Parasitologica 46[1] 67-75 (1999)  

The study of the bulla from 18 lernaeopodid copepod species collected on 15 marine fish species and one freshwater fish species taken mainly from the Gulf of Lions in the Mediterranean Sea reveals a great morphological and structural variability. It is however possible to bring forth three general remarks: - the bulla of Lernaeopodidae parasites of Selachii have a remarkably constant structure probably due to the tegument nature of the attachment substratum; - the bulla of Lernaeopodidae parasites of Teleostei has a morphology influenced by the nature of the attachment tissue; - when species of a same genus (i.e. Clavellotis) are attached on...

Lectin-like sequences in genome of Borrelia burgdorferi

Nataliia Rudenko, Maryna Golovchenko, Libor Grubhoffer

Folia Parasitologica 46[2] 81-90 (1999)  

Using degenerative primers designed on the basis of known sequences of lectin genes from different sources a fragment of genomic DNA of Borrelia burgdorferi ( strain B31) that contained a lectin-like sequence was isolated, cloned and sequenced. The presence of an open reading frame of 268 amino acids (position 1501-2304 bp) and the computer analysis of the predicted amino acid sequence showed 37% of identity and 75% of homology over region of 25 amino acids with the legume lectin proteins, including erythroagglutinating phytohemagglutinin (PHA-E) and leucoagglutinating phytohemagglutinin (PHA-L). The further analysis of the predicted amino acid...

Morphology and taxonomy of Salvelinema species (Nematoda: Cystidicolidae), swimbladder parasites of Pacific area salmonids

František Moravec, 2and Kazuya Nagasawa

Folia Parasitologica 46[2] 123-131 (1999)  

The morphology of two Salvelinema Trofimenko, 1962 species, S. salmonicola (Ishii, 1916) and S. walkeri (Ekbaum, 1935), swimbladder nematodes of salmonids, was studied in detail, including scanning electron microscopy (SEM), on the basis of newly collected materials from Oncorhynchus masou, O. mykiss and Salvelinus malma from Japan and from Oncorhynchus clarki, O. kisutch and O. nerka from North America (Vancouver Island, B.C., Canada and Gulf of Alaska). Both nematode species proved to be morphologically very similar, differing substantially in the numbers and arrangements of egg filaments....

Parasitic copepods of the narrownose smooth-hound shark Mustelus schmitti (Chondrichthyes: Triakidae) from Argentina

Jorge A. Etchegoin, Verónica A. Ivanov

Folia Parasitologica 46[2] 149-153 (1999)  

The parasitic copepod fauna of 182 specimens of Mustelus schmitti Springer from the coast of Mar del Plata, Argentina was investigated. Three species of parasitic copepods were identified: Nessipus orientalis Heller, 1865 from the buccal cavity, Perissopus oblongus (Wilson, 1908) from the edge of pectoral, pelvic, dorsal, anal and caudal fins and in claspers, and Lernaeopoda galei Krøyer, 1837 from the base of the pectoral fins. N. orientalis was most common being present the entire year, while P. oblongus and L. galei occurred seasonally with low prevalence and mean intensity. There were differences...

On the development and life cycle of Camallanus anabantis (Nematoda: Camallanidae), a parasite of the climbing perch, Anabas testudineus

Nimai C. De

Folia Parasitologica 46[3] 205-215 (1999)  

The developmental stages and life cycle of the nematode Camallanus anabantis Pearse, 1933 an intestinal parasite of Anabas testudineus (Bloch) are described. The copepod Mesocyclops leuckarti (Claus) was used as experimental intermediate host. After being ingested by the copepods the nematode first-stage larvae enter its haemocoel, where they moult twice, 4 d.p.i. and 11 d.p.i., at 21-26°C, respectively to become the infective third-stage larvae. The definitive fish hosts become infected when feeding on copepods harbouring infective larvae. In the fish host's intestine the larvae undergo two more moults, the third on day 15 p.i....

Bacillary band ultrastructure of the fish parasite Capillaria pterophylli (Nematoda: Capillariidae)

Zdeňka Žďárská, Jana Nebesářová

Folia Parasitologica 47[1] 45-48 (2000) | DOI: 10.14411/fp.2000.008  

In Capillaria pterophylli Heinze, 1933, two lateral bacillary bands extend along the whole body in female and male worms. A ventral bacillary band is present in females only. The bacillary bands consist of glandular and non-glandular cells, and in the region between the nerve ring and the end of the stichosome, ciliated sense receptors in tight connection with gland cells are present.

A redescription of the adult male of Caecognathia cryptopais (Barnard, 1925) is provided from syntypes and other material deposited in the South African Museum. The generic status of Caecognathia cryptopais is also revised. This redescription is based on light and scanning electron microscopy.

Ultrastructural study of meronts and gamonts of Choleoeimeria rochalimai (Apicomplexa: Eimeriidae) developing in the gall bladder of the gecko Hemidactylus mabouia from Brazil

Ilan Paperna, Ralph Lainson

Folia Parasitologica 47[2] 91-96 (2000) | DOI: 10.14411/fp.2000.019  

Endogenous development of Choleoeimeria rochalimai (Carini et Pinto, 1926) Lainson et Paperna, 1999 in the gall bladder of Hemidactylus mabouia (Moreau de Jonnes, 1818) from Belém, Brazil is reported at the fine structural level. Meronts and gamonts develop in the epithelial cells of the gall bladder. Infected cells become enlarged and displaced above the epithelial layer. Developing merozoites, dividing meronts and succession of developing microgamonts from initial nuclear division up to final microgamete differentiation are described. In addition to wall forming bodies, mature macrogamonts possess a large inclusion or cisterna with...

Rhabdochona mexicana sp. n. (Nematoda: Rhabdochonidae) from the intestine of characid fishes in Mexico

Juan Manuel Caspeta-Mandujano, František Moravec, Guillermo Salgado-Maldonado

Folia Parasitologica 47[3] 211-215 (2000) | DOI: 10.14411/fp.2000.039  

A new nematode, Rhabdochona mexicana sp. n., is described based on specimens recovered from the intestine of two species of fishes, Astyanax mexicanus (De Filippi) (type host) and Astyanax fasciatus (Cuvier) (Characidae: Characiformes) in central Mexico. This species is characterised by the following characters: 10 anteriorly directed teeth in the prostom, a larger (left) spicule which is slender in form with a small bifurcation at its distal tip covered by a cuticular membrane, a smaller (right) spicule without a barb at its distal tip, eggs bearing an irregular flock-like coating, and a conical tail without a cuticular spike...

A 33-35 kDa circulating antigen from Plasmodium falciparum

Neirade Dominguez, Alexis Rodriguez-Acosta

Folia Parasitologica 47[4] 267-272 (2000) | DOI: 10.14411/fp.2000.046  

Isolation and characterisation of Plasmodium falciparum (Welch, 1897) soluble antigens from infected patient plasma, Western blotting, thermal stability and ELISA assays using hyperimmune IgG-antimalaria antibodies was the main objective of this work. A circulating antigen of approximately Mr 33-35 kDa with good specificity and antigenicity, in the plasma of malarial patients was shown. Heating at 100ºC did not destroy its antigenicity. When fractions highly enriched in the 33-35 kDa proteins were used in ELISAs, a seroreactivity in plasma obtained from primary-infected individuals was found. Controls from normal patients were always negative....

Harry W. Palm, Robin M. Overstreet

Folia Parasitologica 47[4] 293-302 (2000) | DOI: 10.14411/fp.2000.051  

Four trypanorhynchs, Kotorella pronosoma (Stossich, 1901), Nybelinia cf. bisulcata (Linton, 1889), Nybelinia scoliodoni (Vijayalakshmi, Vijayalakshmi et Gangadharam, 1996), and Dasyrhynchus pacificus Robinson, 1965 are reported for the first time from the Gulf, which is now known to harbour at least 34 different species. In addition to the range extension for the trypanorhynchs listed above, 21 new host records are reported involving 13 cestode species. Characters of the genus Kotorella Euzet et Radujkovic, 1989 are emended, Nybelinia narinari MacCallum, 1917 is considered a junior synonym of Kotorella...

Comparison of the Galleria baiting technique and a direct extraction method for recovering Steinernema (Nematoda: Rhabditida) infective-stage juveniles from soil

Dieter Sturhan, Zdeněk Mráček

Folia Parasitologica 47[4] 315-318 (2000) | DOI: 10.14411/fp.2000.055  

Forty soil samples from forests and other biotopes in Germany and the Czech Republic were studied for the presence of entomopathogenic nematodes using the Galleria bait method at the same time as a sieving-decanting method for direct extraction of infective-stage juveniles. Five Steinernema species were recovered from the samples from Germany and four species from the samples from Czechia. All five species were recovered with both methods, but the baiting technique was generally less effective and mixtures of species were frequently undetected. The direct extraction method provided quantitative estimates of infective-stage juvenile density...

New feather mite species of the family Pteronyssidae (Astigmata: Analgoidea) from South African passerines (Aves: Passeriformes)

David Modrý, Jan R. Šlapeta, Zdeněk Knotek, Břetislav Koudela

Folia Parasitologica 48[1] 7-10 (2001) | DOI: 10.14411/fp.2001.002  

Parasitological examination of two ornate Nile monitors Varanus ornatus (Daudin, 1803) imported from Benin revealed the presence of a new species of Caryospora. Oocysts of Caryospora varaniornati sp. n. are spherical to slightly subspherical, 12.0 (11-12.5) × 11.5 (11-12) µm, without a micropyle and oocyst residuum, and occasionally possessing one small polar granule. Sporocysts are broadly ellipsoidal, 8.8 (8.5-9.5) × 6.7 (6.5-7) µm; a lentil-like Stieda body is present, ca. 0.5 × 1 µm; substieda body not visible. Experimental infection of a closely related host, Varanus niloticus (L.), did not lead to...

Jiří Volf, David Modrý, Břetislav Koudela

Folia Parasitologica 48[1] 11-14 (2001) | DOI: 10.14411/fp.2001.003  

Four laboratory-hatched European kestrels Falco tinnunculus L. were fed on laboratory mice and common voles Microtus arvalis Pallas previously inoculated with different doses of sporulated oocysts of Caryospora kutzeri Böer, 1982. Two kestrels that were fed infected mice shed C. kutzeri oocysts 6 days after ingesting murine tissues. To compare direct and indirect transmissions, two of the kestrels were subsequently directly inoculated with 10⁵ sporulated C. kutzeri oocysts and became patent on days 8 and 9 and shed caryosporan oocysts up to day 25 post inoculation. Additionally, four mice were inoculated...

Salah Bouamer, Serge Morand, Robert Bourgat

Folia Parasitologica 48[2] 132-138 (2001) | DOI: 10.14411/fp.2001.020  

The generic diagnosis of Mehdiella Seurat, 1918 is emended based on study and redescription of Mehdiella microstoma (Drasche, 1884) from the caecum of Testudo graeca Linnaeus, 1758 collected in Settat, Morocco and on study and description of a new species, Mehdiella petterae sp. n., from the large intestine of Testudo hermanni (Gmelin, 1789) collected in Catalonia, Spain. Scanning electron microscopy (SEM) studies revealed substantial differences in the structure of the mouth and the caudal end, and made possible to differentiate the new species from the others. SEM studies showed the real and sound characteristics...

Chaetotaxy of the monogeneans Macrogyrodactylus clarii and M. congolensis from the gills and skin of the catfish Clarias gariepinus in Egypt, with a note on argentophilic elements in the nervous system

Mohammed M. El-Naggar, Safaa Z. Arafa, Sameer A. El-Abbassy, Graham C. Kearn

Folia Parasitologica 48[3] 201-208 (2001) | DOI: 10.14411/fp.2001.033  

A comparison has been made between the chaetotaxy of the gyrodactylid monogeneans Macrogyrodactylus clarii Gussev, 1961 and M. congolensis (Prudhoe, 1957) Yamaguti, 1963 from the gills and skin, respectively, of the catfish Clarias gariepinus (Burchell) from the river Nile in Egypt. Bilaterally arranged argentophilic structures on the surface of these parasites are presumed to be sensilla and are more abundant in M. clarii than in M. congolensis especially on the ventral surface (124 vs. 66). In both species these sensilla are concentrated on the head lobes and in the pharyngeal region, but there are features of the...
