The recognition of cryptic parasite species has implications for evolutionary and population-based studies of wildlife and human disease. Echinostome trematodes are a widely distributed, species-rich group of internal parasites that infect a wide array of hosts and are agents of disease in amphibians, mammals, and birds. We utilize genetic markers to understand patterns of morphology, host use,...

In Southeast Asia, a total of 59 species of foodborne intestinal flukes have been known to occur in humans. The largest group is the family Heterophyidae, which constitutes 22 species belonging to 9 genera (Centrocestus, Haplorchis, Heterophyes, Heterophyopsis, Metagonimus, Procerovum, Pygidiopsis, Stellantchasmus, and Stictodora). The next is the family Echinostomatidae, which includes 20 spec...

Micro-scale analytical techniques permit correlation of chemistry with morphology of individual Proterozoic acritarchs (organic-walled microfossils), and thus provide new approaches for elucidating their biological affinities. A combination of micro-Fourier transform infrared (FTIR) spectroscopy and laser micro-Raman spectroscopy was used to investigate the organic structure and composition of ...

Abstract Acritarch biostratigraphic and δ 13 C chemostratigraphic data from the Krol A Formation in Solan area (Lesser Himalaya, northern India) are integrated to aid inter-basinal correlation of early–middle Ediacaran strata. We identified a prominent negative excursion (likely equivalent EN2 lower Doushantuo Yangtze Gorges South China), over dozen species acanthomorphs (including two new spec...

Актуальность. Вывихи акромиального конца ключицы являются довольно распространенным травматическим повреждением опорно-двигательного аппарата. Данное повреждение составляет 3–26,1 % от общего количества вывихов других локализаций и занимает третье место после плеча предплечья. Встречается преимущественно у мужчин молодого, трудоспособного возраста. Неудовлетворительные результаты лечения пациен...

As part of the most common eukaryotic fossils in early Ediacaran strata, acanthomorphic acritarchs are crucial for understanding biostratigraphy and evolutionary dynamics marine eukaryotes after Marinoan global glaciation. Abundant diverse have been reported from Doushantuo Formation Yangtze Gorges area, South China, different biozonation schemes proposed. However, these previously published bi...

KURIS, A. M., 1973. Biological control: implications of the analogy between the trophic interactions of insect pest-parasitoid and snail-trematode systems. Experimental Parasitology 33, 365-379. An analogy between the tropic interactions of insect pest-hymenopterous parasitoid and snail-larval trematode systems is proposed. The goal of most agricultural pest management programs is increase in p...
