The expansion of parasite distributions outside of their native host and geographical ranges has occurred repeatedly over evolutionary time. Contemporary examples include emerging infectious diseases (EID's), many of which pose threats to human, domestic animal, and wildlife populations. Theory predicts that parasites with complex life cycles will be rare as EID's due to constraints imposed by host specialization at each life-cycle stage. In contrast to predictions of this theory, we report 2 new intermediate hosts in the 3-host life cycle of the liver fluke Dicrocoelium dendriticum in Cypress Hills Provincial Park, Alberta, Canada...

This study investigated the presence of Hepatozoon spp. in jaguars (Panthera onca) and domestic animals in the Cerrado, Amazon and Pantanal biomes of Brazil. Between February 2000 and January 2010, blood samples were collected from 30 jaguars, 129 domestic dogs (Canis lupus familiaris) and 22 domestic cats (Felis catus) for molecular tests. All of the jaguars from the Pantanal (n=22) and Cerrado (n=4) and 3 of 4 jaguars from the Amazon were positive for Hepatozoon spp. Domestic dogs (62.8%) and cats (31.8%) were also positive for the agent...

Ruminants infected by Paramphistomidae flukes shed eggs in the feces, which pass through different stages in the environment until the infective stages (metacercariae) are reached. The activity of the soil fungus Mucor circinelloides on the development of eggs of the rumen fluke Calicophoron daubneyi was presently tested with 3 probes, i.e., in Petri plates, feces and an aqueous environment (tubes). The effect of the fungus was assessed by recording the numbers of undeveloped, non-viable and embryonated eggs...

We found hundreds of mites behind the eyes of a Double-crested Cormorant, Phalacrocorax auritus (Suliformes: Phalacrocoracidae). The mites were Neottialges evansi (Acari: Hypoderatidae), representing the first report of this parasite in P. auritus from western North America. Deutonymphs of N. evansi are endoparasites, typically reported infecting fat deposits over the pectoral muscles, axillary areas, and vent of cormorants. Here, mites infected only orbital tissues, a new infection site for hypoderatid mites...

This study investigates the systematic position of some species of the genus Saccocoelioides Szidat, 1954, and the species Culuwiya cichlidorum Aguirre-Macedo and Scholz, 2005 from North and Middle America using new morphological data and partial sequences of 2 nuclear genes, the large subunit (LSU) and the internal transcribed spacer 2 (ITS2) from ribosomal DNA. In total 74 specimens representing 4 species of Saccocoelioides (41 of Saccocoelioides sogandaresi, 3 of Saccocoelioides chauhani, 6 of Saccocoelioides lamothei, and 12 of Saccocoelioides olmecae) plus 12 specimens of Culuwiya cichlidorum were analyzed...

Here we report a case of ulcerative caseous gastroesophagitis associated with Rameshwarotrema uterocrescens; Rao, 1975 (Digenea: Pronocephalidae) in a juvenile green turtle (Chelonia mydas) from Southern Brazil. Similar pathologies have been reported only in adult green turtles from Costa Rica. This paper presents the second report of parasitic esophagitis due R. uterocrescens and the first occurrence in juvenile green turtles along coastal Brazil.

There is considerable confusion concerning the identity of macroscopic Sarcocystis species in camels. Currently 2 species: Sarcocystis cameli, and Sarcocystis ippeni are recognized from 1-humped camel (Camelus dromedarius), and sarcocysts of both species are microscopic. Here, we report identity of macroscopic sarcocysts from the C. dromedarius in Iraq as Sarcocystis cameli. Five sarcocysts from the muscle of 2 adult camels collected in 1999 and stored in 10% formalin were studied by transmission electron microscopy (TEM)...

Anaplasma phagocytophilum is a zoonotic pathogen and the causative agent of human granulocytic anaplasmosis (HGA) in humans and tick-borne fever in various kinds of animals. In the present study, a loop-mediated isothermal amplification (LAMP) assay for rapid detection of A. phagocytophilum was developed using primers specific to 16S rRNA gene of this organism. The LAMP assay was performed at 65 C for 60 min and terminated at 80 C for 10 min. The optimal reaction conditions, under which no cross-reaction was observed with other closely related tick borne parasites (Anaplasma bovis, Anaplasma ovis, Theileria luwenshuni, Babesia motasi and Schistosoma japonicum) was established...

The ubiquity of host-parasite interactions and their potential for substantial representation, in terms of overall biomass, within ecosystems suggests that parasites have the capacity to influence energy flow within an ecosystem. While the influence of certain parasites on prey behavior has been well-documented, parasites could also exert an influence on ecosystem dynamics by influencing predator feeding behavior. The functional response of Tetragoneuria naiads was characterized by presenting naiads with varying abundances of Daphnia magna, after which a subset of the naiads were exposed to cercariae of Haematoloechus floedae, and the feeding trials repeated for both the control and exposed odonates...

Haemonchus contortus is one of the most significant strongylid nematodes infecting small ruminants and causes great economic losses to the livestock industry worldwide. Accurate diagnosis of H. contortus is crucial to control the infection. Traditional microscopic examinations are the most common methods for the diagnosis of H. contortus, but they are time-consuming and inaccurate. Molecular methods based on PCR are more accurate, but need expensive machines usually only used in the laboratory. Loop-mediated isothermal amplification (LAMP) is a rapid, simple, specific and sensitive method that has been widely used to detect viruses, bacteria and parasites...

This study compares the helminth faunas between Cope's gray treefrogs (Hyla chrysoscelis) and green treefrogs (Hyla cinerea) in areas where they have recently overlapped due to range expansion by H. cinerea, to determine whether or not 2 species of frogs with a high degree of similarity in many of their life history traits also exhibit similarities in the composition of their helminth assemblages. Results of this study did not find significant differences in helminth species diversity when sympatric and allopatric populations of the same species of frog were compared...

Host associations of highly host-specific chewing lice (Insecta: Phthiraptera) across multiple avian species remains fairly undocumented in the West African country of Benin. Two hundred and seventeen bird specimens collected from multiple localities across Benin and housed at the Texas A&M University Biodiversity Research and Teaching Collections were examined for lice. Lice were identified and genetic data (mitochondrial COI and nuclear EF-1α genes) were obtained and phylogenetically analyzed. In total, we found 15 host associations, 7 of which were new to science...
