Nagah Arafat, Ibrahim Abass
A systematic study was taken to identify the species, characterize the pathogencity and assess the immunization of Eimeria bateri in Japanese quails (Coturnix coturnix japonica). In total, 107 Japanese quail farms were examined. The samples were processed and oocysts shape indices of sporulated oocysts were determined. Out of 107 examined farms 34 (31.78%) farms were positive. Four Eimeria spp. were morphologically identified. For characterization of the pathogencity, Japanese quails were orally inoculated with various doses of sporulated oocysts of Eimeria bateri...

Plasmodium spp. are haemosporidian protozoans that alternate their live cycles between bloodsucking Culicidae dipterans and vertebrate hosts (mammals, reptiles and birds). In birds, these parasites are the causative agents of the so called avian malaria, a disease associated with considerable declines and extinctions in the avifauna in different geographical regions. In this work, we applied a multidisciplinary approach, light microscopy and cytochrome oxidase b (cyt b) gene sequence analysis for characterization of Plasmodium found in association with wild birds of the genus Turdus, collected in Atlantic forest fragments of southeastern Brazil...

A taxonomic study of monozoic cestodes of the genus Glaridacris Cooper, 1920 (Cestoda: Caryophyllidea), parasites of catostomid fishes in North America, confirmed artificial character of the genus which is split to 2 different, morphologically distinct and not closely related genera. Glaridacris is newly circumscribed to include only 3 species, Glaridacris. catostomi Cooper, 1920 (type species), Glaridacris. terebrans (Linton, 1893) and Glaridacris. vogei Mackiewicz, 1976, which are characterized by an elongate body, a cuneiloculate or wedge-shaped scolex with six 6 shallow loculi, male and female gonopores at a distance from each other, follicular ovary and circum-medullary vitelline follicles (lateral and median)...

Ribosomal protein S9 (RPS9) is an essential functional gene that participate in DNA repair and developmental regulations. A sequence homolog of RPS9 has been found to be upregulated in the protoscoleces (PSCs) of Echinococcus granulosus treated with artemisinin (ART). However, Echinococcus granulosus RPS9 (EgRPS9) has not been identified before. In the present study, the 657 bp cDNA encoding EgRPS9 was cloned. Amino acid sequence analysis showed that EgRPS9 was similar to the RSP9 proteins from Schistosoma japonicum (SjRPS9, 86 %) and Schistosoma mansoni (SmRPS9, 79 %)...

The acanthocephalan Paratrajectura longcementglandatus n. gen., n. sp. (Transvenidae) is described from specimens of 2 perciform fish species, Nemipterus japonicus Bloch (Nemipteridae) and Otolithes ruber Bloch and Schneider collected in the marine territorial waters of Iraq and Iran in the Arabian Gulf. Metal analysis of hook tip, middle and base is also described using X-ray microanalysis EDAX. The new genus is distinguished from the closely related genus Trajectura Pichelin and Cribb, 2001 described from wrasses (Labridae) (Perciformes) in the Pacific off Australia and Japan by having a proboscis with apical epidermal cone, long rhadinorhynchid-like tubular cement glands, relatively short and lobulated lemnisci, all proboscis hooks with prominent roots, females with subterminal gonopore and a rounded projection on the antero-dorsal end of the trunk, and males with elongate pre-equatorial testes reaching proboscis receptacle...

Caridean shrimp are critical components of seagrass communities and occasionally harbor parasitic bopyrid isopods, which can negatively impact their hosts. However, the ecological factors that drive infection rates of parasitic bopyrid isopods in host carideans are poorly known. We examined 43,785 carideans belonging to 6 families and 11 genera from 19 shallow-water localities throughout south Florida. Of these, only 114 shrimp (belonging to 5 genera) were found to be infested with bopyrids (an additional 251 had deformed carapaces consistent with recent infestation)...

We report the finding of 2 species of Pudica (Nematoda: Heligmonellidae: Pudicinae) in 2 rodents endemic to Chile, the Common Degu Octodon degus (Octodontidae) and the Bennett's Chinchilla Rat Abrocoma bennettii (Abrocomidae). Pudica degusi (Babero and Cattan, 1975) n. comb., originally described as a species of Longistriata (Heligmosomidae), was found in the Common Degu; through the study of its synlophe, the species is reassigned to the Heligmonellidae: Pudicinae and the genus Pudica, and is revalidated through comparison with the remaining species of the genus...

It is rare that an organism capable of independent or commensalistic existence can also become endoparasitic on a host. In this study, we documented a potential step toward parasitism in the commensal clam Kurtiella pedroana (Bivalvia: Galeommatoidea). Galeommatoideans are known commensals of various invertebrates, including crustaceans. Emerita analoga (Decapoda: Hippidae) is an abundant intertidal decapod inhabiting sandy beaches of the Pacific coast of North and South America. Crabs collected from Monterey Bay, California, were measured and examined externally and internally for associated molluscs...

The spread of parasites through a host population is based on the variation in behavior and immune function between individuals and is rarely uniform. We studied the gastrointestinal parasites of common mole-rats (Cryptomys hottentotus hottentotus, Lesson 1826) from 2 sites and assessed the levels of infection based on host sex, breeding status and season. Only nematode species were found; Neoheligmonella sp. and Mammalakis macrospiculum, (Ortlepp, 1939) and a single specimen of Trichuris sp., all of which have direct life cycles...

Neospirorchis (Digenea: "Spirorchiidae") are blood flukes of sea turtles. Trematodes tentatively identified as Neospirorchis sp. infect various sites within sea turtles inhabiting waters of the southeastern United States, but efforts to obtain specimens adequate for morphologic study has proven difficult. Two genetic targets, the internal transcribed spacer region of the ribosomal RNA gene and the partial mitochrondrial cytochrome c oxidase subunit I gene, were used to investigate potential diversity among parasite specimens collected from stranded sea turtles...

B-1 cells are a subtype of B cells with peculiar characteristics. These cells are distinct from B-2 lymphocytes in their morphology, ontogeny, tissue distribution and phenotypic functional features. B-1 cells can participate in the immune response in several ways, for example, by being recruited to inflammatory foci, producing large amounts of IL-10 cytokine, and differentiating into IgM-secreting cells or phagocytes. Nevertheless, the role of B-1 cells in the pathogenesis of experimental leishmaniasis has not been fully elucidated...

Here we report a new species of Sarcocystis with Barred owls as the natural definitive host and interferon gamma gene knockout (KO) mice as an experimental intermediate host. A Barred owl submitted to the Carolina Raptor Center, Huntersville, North Carolina, was euthanized because of paralysis. Fully sporulated 12.5 x 9.9 m sporocysts were found in intestinal scrapings from the owl. Sporocysts from the Barred owl were orally fed to 4 laboratories reared outbred Swiss Webster (SW) (Mus musculus) and 8 KO mice...

Carnivorous mammals are a trophic guild with an important role in the dissemination of parasite infective stages (larvae, eggs, cysts, and oocysts). In the present study, new samples of coprolites attributed to carnivorous mammals, obtained from two archaeological caves, were analyzed for the presence of parasites, with the aim to increase the knowledge about parasites in rockshelters that could have spread to humans and other mammals. To this purpose, fragments of 3 coprolites from Cerro Casa de Piedra, cave 5 (CCP5) and cave 7 (CCP7) were examined...
