This invention is a trap to collect worms or fly larvae to be used as feed or fowl. Putrid meat is placed inside a a box on top of a metal screen. It is desired to have flies be attracted to the putrid meat and lay their eggs on it. Underneath the meat on top of the screens, warm, wet humus or newspaper is placed and serves as nourishment for the worms when they are hatched. When the larvae are feeding, the screen can be removed in a way to keep the larvae on top and serve as feed for poultry.

This invention provides a high throughput survival assay, using uptake of a marker dye (e.g. a fluorescent dye) as a marker of death of a nematode. The assay permits high throughput screening of thousands of compounds possible. By the application of automated worm handling technology we are able to accurately dispense nematodes into 384 well microtitre plates, at rates many thousand of Limes faster than previously possible. In addition, we have automated the analysis of survival by the use of a fluorometric plate reader that quantitates the degree of fluorescence within each well.

Filarial parasites Brugia, Wuchereria, Loa Loa and Onchocerca cause over 20 million infections worldwide and pose a significant social and economic burden in endemic areas. The invention provides compositions and methods to treat parasitic infections in animals and plants, and to kill and inhibit the replication of parasites in infected hosts. The methods can include administering to a host in need of treatment an effective antiparasitic amount of a composition comprising biodegradable polyanhydride microparticles or nanoparticles that encapsulate antiparasitic agents, optionally in combination with antibacterial agents. Through co-encapsulation of antiparasitic and antibacterial agents into the particles, the invention provides the ability to effectively kill parasitic helminthes, worms, and flukes, with up to a 40-fold reduction in the amount of drug used. The results described herein demonstrate the effectiveness of the drug carriers to reduce both the course of treatment and the amount of drug needed to treat parasitic infections.

This invention is a method of preserving without any chemical additives Ceratomia catalpae larvae (Catalpa worms) for use as fish bait by cleansing, blanching, and subsequently freezing them in sealed, moisture and vapor limiting bags. The larvae is first chilled as to limit mobility, then picked clean and rinsed with water. The larva is then blanched in boiling water, immersed in cold water to limit cooking and dried. With the use of sterilized tongs, the larvae is then placed in individual plastic bags and frozen within another bag to limit freezer burn. The individual bags of Catawba worms can be thawed out and the worms fished within months after they are harvested with minimal deterioration.

Mammals are treated for infections or for conditions associated with pathologically proliferating mammalian cell growth by administration of a manipulator of nitrosative stress to selectively kill or reduce the growth of the microbes or helminths causing the infection or of host cells infected with the microbes or of the pathologically proliferating mammalian cells. Novel agents include α-alkyl-S-alkyl-homocysteine sulfoximines wherein the α-alkyl contains 2 to 8 carbon atoms, and the S-alkyl contains 1 to 10 carbon atoms. Mammals in need of increased nitrosative stress defenses are treated, e.g., humans at risk for a stroke because of having had a transient ischemic attack, are treated. Treatments to increase nitrosative stress defenses include repeated administrations of low doses of manipullators of nitrosative stress so that subject treated has increased tolerance to nitrosative stress. Mammals are treated for protozoal infections by systemic administration of L-buthionine-S-sulfoximine and agent that increases nirtrosative stress.

The invention discloses a multilayer-shell wormlike mesoporous silica material and a preparation method thereof. The preparation method includes the steps of firstly, sequentially adding cetyltrimethyl ammonium bromide (CTAB) and didodecyldimethyl ammonium bromide (DDAB) into water, stirring for dissolving, adding beta-CD, and stirring to achieve complete dissolving; secondly, adding ammonia water into the solution obtained in the first step, evenly stirring, and adding tetraethyl orthosilicate (TEOS) to obtain suspension; thirdly, continuously performing stirring reaction on the suspension obtained in the second step to obtain a white sediment solution, and performing solvent thermal treatment on the white sediment solution; fourthly, filtering, washing, drying and grinding the white sediment solution after the solvent thermal treatment, and calcining to obtain multilayer-shell wormlike mesoporous silica. The multilayer-shell wormlike mesoporous silica has a multilayer-shell structure with 3-4 layers and large cavities and has evident advantages in fields such as drug controlled release.
