A new species of parasitic nematode, Capillostrongyloides congiopodi n. sp. (Capillariidae), is described based on specimens collected from the gall bladder of the horsefish, Congiopodus peruvianus Cuvier and Velenciennes (Congiopodidae, Scorpaeniformes), from the Patagonian Shelf, Argentina (45...
The irregular presence and low abundance of wild triatomines inside domiciles make their detection more difficult than that of domiciled species, so that vector surveillance and evaluation of Chagas disease transmission risk are more challenging. We compared timed manual searches, considered as ...
A survey was performed between June and September 2006 along the Portuguese coast to assess the prevalence of digenean parasitism in the netted whelk Nassarius reticulatus, a bioindicator of tributyltin (TBT) pollution. It was also intended to evaluate the effect of parasites on the reproduction...
Little is known concerning the epidemiology of Toxoplasma gondii infection in people and animals in rural Mexico. Serum samples and tissues from 150 dogs (Canis familaris), 150 cats (Felis catus), 65 opossums (Didelphis virginianus), 249 rats (Rattus spp.), 127 mice (Mus musculus), and 69 squirr...
Besnoitia besnoiti was isolated from a skin biopsy of a chronically infected cow from central Spain. Zoites released from macroscopic cysts were adapted to its culture in vitro on a MARC-145 cell monolayer. Tachyzoites produced in vitro were either cryopreserved or used for genomic DNA isolation...
A new nematode species, Freitascapillaria moraveci n. sp., is described; it was obtained from specimens recovered from the gall bladder of the 2-spot livebearer Heterandrá bimaculata (Heckel, 1848) from La Antigua River, State of Veracruz, Mexico. The new species is assigned to Freitascapillaria...
As shown previously, the nested PCR method of detection of avian blood parasites, commonly referred to as Waldenström's method, sometimes amplifies only 1 parasite species of the several that may be present in the same bird, and not always the one with the highest parasitemia. This result raises...
The epidemiology of Toxoplasma gondii infection in pregnant women in rural Mexico is largely unknown. The seroepidemiology of T. gondii infection in 439 pregnant women from 9 communities in rural Durango State, Mexico was investigated. Using commercial enzyme-linked immunoassays, sera were teste...
Pectoral muscles from a captive keel-billed toucan (Ramphastos sulfuratus) from Costa Rica were fed to a Toxoplasma gondii-free cat, and the cat shed oocysts. Laboratory mice fed these oocysts developed antibodies to T. gondii in their sera and T. gondii tissue cysts in their brains. The DNA ext...
The louse genera Brueelia (Ischnocera) and Myrsidea (Amblycera) are broadly codistributed on songbirds (Passeriformes), but differ in a variety of life history characteristics. We used mitochondrial and nuclear DNA sequences to assess levels of genetic divergence and reconstruct phylogenies of t...
