There are many strategies to control leishmaniasis, but majority of them are inadequate. Killed Leishmania vaccine (KLV) has been applied for its immunogenicity in human and mouse model. Bacillus Calmette-Guerin (BCG) as adjuvant is an immunemodulator inducing humoral and cellular immune responses during zoonotic cutaneous leishmaniasis (ZCL). Both KLV and BCG have been applied for their immune responses in hosts for controlling leishmaniasis. In this study, KLV and BCG were applied to inhibit replication and visceralization of Leishmania major in BALB/c mice. Mice were injected with KLV and BCG, followed by infection with promastigotes...

A digenean parasite in a mudskipper: Opegaster ouemoensis sp. n. (Digenea: Opecoelidae) in Periophthalmus argentilineatus Valenciennes (Perciformes: Gobiidae) in the mangroves of New Caledonia

Folia Parasitologica 60[1] 7-16 (2013) | 10.14411/fp.2013.002

Opegaster ouemoensis sp. n. is described from Periophthalmus argentilineatus Valenciennes (Gobiidae). Distinctive features included the weak or undetectable papillae of the ventral sucker and the small, but distinct cirrus-sac. The new species is compared with 25 marine species of Opegaster for which a table of measurements and ratios is presented. The new combination Opegaster queenslandicus (Aken'Ova, 2007) (originally in Opecoelus) is formed. Fifteen mudskippers were intensively examined for parasites; larval anisakid nematodes and acanthocephalans were found, but no monogeneans, cestodes, copepods, isopods, hirudineans...

Cardicola langeli sp. n. (Digenea: Aporocotylidae) from heart of sheepshead, Archosargus probatocephalus (Actinopterygii: Sparidae) in the Gulf of Mexico, with an updated list of hosts, infection sites and localities for Cardicola spp.

Cardicola langeli n. sp. (Digenea: Aporocotylidae) infects the heart of sheepshead, Archosargus probatocephalus (Walbaum, 1792) (Perciformes: Sparidae) in the northern Gulf of Mexico off Horn Island (type locality), Mississippi, USA. The new species is described herein using light and scanning electron microscopy of adult specimens and can be most easily distinguished from the other 24 accepted species of Cardicola Short, 1953 by the combination of having (i) an ovovitelline duct that extends anteriad and that (ii) is posterior to the ootype, (iii) a male genital pore that is lateral to the oviducal seminal receptacle and (iv)...

Induction of prominent Th1 response in C57Bl/6 mice immunized with an E. coli-expressed multi T-cell epitope EgA31 antigen against Echinococcus granulosus

First step in developing an epitope-based vaccine is to predict peptide binding to the major histocompatibility complex (MHC) molecules. We performed computational analysis of unique available EgA31 sequence to locate appropriate antigenic propensity positions. T-cell epitopes with best binding affinity values of < 50% inhibitory concentration were selected using different available servers (Propred and IEDB). Peptides with 100% population coverage were selected. A DNA fragment corresponding to the furin linker enriched in Golgi apparatus was inserted sequentially between each epitope sequences in a synthetic DNA in order to cleave the chimeric...

First description of adults of the type species of the genus Glossocercus Chandler, 1935 (Cestoda: Gryporhynchidae)

The type species of the genus Glossocercus Chandler, 1935, G. cyprinodontis Chandler, 1935, was described as metacestode (larval stage) from the mesentery of the sheepshead minnow fish (Cyprinodon variegatus Lacépède) from Galveston Bay, Texas. The description was based on the morphology of the rostellar hooks; however, the features of the internal morphology of the proglottides could no be provided. In the present study we describe for the first time the features of the adult G. cyprinodontis from the intestine of Pelecanus occidentalis Linnaeus, Nycticorax nycticorax Linnaeus and Egretta rufescens...

A reinvestigation of spermiogenesis in Amphilina foliacea (Platyhelminthes: Amphilinidea)

Folia Parasitologica 60[1] 43-50 (2013) | 10.14411/fp.2013.006

Spermiogenesis in the amphilinidean cestode Amphilina foliacea (Rudolphi, 1819) was examined using transmission electron microscopy. The orthogonal development of the two flagella is followed by a flagellar rotation and their proximodistal fusion with the median cytoplasmic process. This process is accompanied by extension of both the mitochondrion and nucleus into the median cytoplasmic process. The two pairs of electron-dense attachment zones mark the lines where the proximodistal fusion of the median cytoplasmic process with the two flagella takes place. The intercentriolar body, previously undetermined in A. foliacea, is composed...

DNA-barcoding contradicts morphology in quill mite species Torotrogla merulae and T. rubeculi (Prostigmata: Syringophilidae)

Folia Parasitologica 60[1] 51-60 (2013) | 10.14411/fp.2013.007

Torotrogla merulae Skoracki, Dabert et Ehrnsberger, 2000 and T. rubeculi Skoracki, 2004 have been considered as distinct steno- and monoxenous quill mite species (Acari: Prostigmata: Syringophilidae) parasitizing the thrushes of the genus Turdus Linnaeus and the European robin Erithacus rubecula (Linnaeus), respectively. Morphological and molecular studies on the taxonomical status of these two species provided contradictory results. Well defined differences in morphology were not supported by substantial genetic distance in nucleotide sequences of the DNA barcode (mitochondrial cytochrome c oxidase subunit I, COI, and...

The genus Hatschekia (Copepoda: Hatschekiidae) from pufferfishes (Tetraodontiformes: Tetraodontidae) off the Ryukyu Islands, Japan, with descriptions of four new species and a redescription of H. pholas

Folia Parasitologica 60[1] 61-74 (2013) | 10.14411/fp.2013.008

Four new species of the genus Hatschekia Poche, 1902 (Copepoda: Siphonostomatoida: Hatschekiidae) are described based on female specimens collected from pufferfishes (Tetraodontiformes: Tetraodontidae) caught in coastal waters off the Ryukyu Islands, Japan: H. longiabdominalis sp. n. on Arothron hispidus (Linnaeus), H. geniculata sp. n. on A. hispidus (type host) and A. stellatus (Bloch et Schneider), H. ellipsocorpa sp. n. on A. mappa (Lesson), and H. boonah sp. n. on A. nigropunctatus (Bloch et Schneider) (type host) and A. meleagris (Schneider). Hatschekia longiabdominalis...

Trafficking of Plasmodium falciparum chimeric rhoptry protein with Brefeldin A

Ahmed M. Ghoneim

Folia Parasitologica 60[1] 75-78 (2013) | 10.14411/fp.2013.009

Trafficking of the rhoptry chimeric protein RhopH2-GFP, which contains RhopH2 signal peptide plus the downstream five amino acids, was dissected by treating parasites with Brefeldin A at three different time points. Twenty eight hrs-stage trophozoites accumulated the chimera within the parasite endoplasmic reticulum. In 32 hrs-stage schizonts, the chimera was distributed in the parasite cytoplasm but not in the parasitophorous vacuole. In 36 hrs stage-schizonts, the chimera was detected in the individual parasitophorous vacuoles of the developing merozoites and, in contrary to non-treated parasites, no immature rhoptry vesicles could be detected in...
