Helminth infracommunities of a population of the Gran Canaria giant lizard Gallotia stehlini
Journal of Helminthology, 2004AbstractA survey of gastro-intestinal helminth communities of Gallotia stehlini (Sauria: Lacertidae) from Gran Canaria island (Canary Archipelago, Spain), was conducted to determine the prevalence, abundance and species diversity of intestinal parasites in these lizards.

AbstractThe structure and composition of parasite communities of Mullus argentinae were analysed under two alternative hypotheses in a sample of 75 specimens caught off Mar del Plata, Argentina (38°27′S, 57°90′W). The first, based on the dominance of trophically transmitted larval parasites of low host-specificity among fish species in the region ...

Retrocarotid Infracommunicating Approach for Parasellar and Interpedunclar Tumors
2007What is minimally invasive? There are many answers: for example less operation time, less blood loss, less damage to the brain, nerves and blood vessels and safety. I think the concept of minimally invasive neurosurgery is less complications and maximum efforts. Surgeons should evaluate the grade of complications preoperatively.

Abstract Parasites were harvested from lungs and gastrointestinal tracts of Alligator mississippiensis from Texas. We compared our results with previous parasitism findings from alligators harvested in 2011 in Louisiana and Florida. Florida alligators exhibited the greatest pentastomid prevalence and mean intensity and illustrated higher stomach ...

A total of 76 adult individuals of Rana vaillanti were collected in Laguna Escondida, Los Tuxtlas, Veracruz, Mexico, and their helminth infracommunity structure was determined. Among the 21 helminth taxa collected (10 digeneans, 8 nematodes, and 3 acanthocephalans), the digenean Langeronia macrocirra reached the highest prevalence (64.4%), mean ...

Within populations the contact rate of hosts and infectious parasites is mediated by the interactions of resource availability, host density, and host behavior. Fluctuations in host density can result in the loss or extinction of a parasite population as contact rates between parasites and susceptible individuals drop below thresholds of parasite ...

Four species assemblages of desmognathine salamanders are sympatric in and along many mountain streams of the southern Appalachians. The species, Leurognathus marmorata, Desmognathus quadramaculatus, D. monticola and D. ochrophaeus, span an aquatic to terrestrial habitat continuum ranging from totally aquatic (L. marmorata) to primarily terrestrial (D.
