Culture solutions of the submerged freshwater macrophytes Hydrilla verticillata and Vallisneria spiralis, separately incubated at 10 g of fresh weight (FW) per liter for three days, were extracted by solid phase extraction (SPE) followed by liquid liquid extraction (LLE), and the acquired ethyl acetate fractions were analyzed by gas chromatograph-mass spectrometry (GC-MS) to identify potential ...
Infection with the parasitic nematode Trichinella spiralis is initiated when the L1 larva invades host intestinal epithelial cells. Monoclonal antibodies specific for glycans on the larval surface and secreted glycoproteins protect the intestine against infection. Protective antibodies recognize tyvelose which caps the target glycan. In this study, we used an in vitro model of invasion to furth...
The removal efficiency of sediment phosphorus (P) in all fractions with in-situ adsorption-biological combined technology was studied in West Lake, Hangzhou, China. The removal amounts of sediment Ca-P, Fe/Al-P, IP, OP and TP by the combined effect of PCFM (Porous ceramic filter media) and V. spiralis was 61 mg/kg, 249 mg/kg, 318 mg/kg, 85 mg/kg and 416 mg/kg, respectively, and the correspondin...
Mice challenged intravenously with Listeria monocytogenes at 7 or 21 days after Trichinella spiralis infection demonstrated a higher mean lethal dose and longer survival time than normal mice. This effect of helminthic infection was abrogated after 49 days.
Immune responses elicited by parasitic worms share many features with those of chronic allergy. Eosinophils contribute to the inflammation that occurs in both types of disease, and helminths can be damaged or killed by toxic products released by eosinophils in vitro. Such observations inform the widely held view that eosinophils protect the host against parasitic worms. The mouse is a natural h...
Expulsion of two gastrointestinal nematode parasites, Nippostrongylus brasiliensis and Trichinella spiralis, is similar in that both require IL-4Ralpha expression, but different in that T cells and mast cells are required for IL-4-induced expulsion of T. spiralis but not N. brasiliensis. To examine the role of IL-4Ralpha signaling in immunity to these parasites, we studied worm expulsion in chi...
KOZEK, W. J. 1975. Trichinella spiralis: Morphological characteristics of male and female intestine-infecting larvae. Experimental Parasitology 37, 380-387. The sex of encysted and excysted intestine-infecting T. spiralis larvae can be distinguished by the following morphological characteristics: the male larva has a long (approx 50 pm) rectum, and the anterior part of the testis is curved post...
