Antimalarial efficacy of skin extract via inhibition of Na/H ATPase.

Unlabelled: Malaria remains a major health issue worldwide that affects many people, particularly in developing nations. Since, the malarial parasite has developed resistance against nearly every antimalarial drug now in use, it is imperative to search for novel antimalarial medications. Toxins produced by skin glands of toads have been shown to possess antiparasitic properties against a variety of protozoan parasites because of the bufadienolides they contain.

Identifying toxic effects and metabolic perturbations of skin extracts in human erythrocytes.

Background: Skin secretions of toads are widely used in medicine all over the world for their antiviral, anti-infective, and cardiotonic properties. Because these secretions are mostly employed to combat blood parasite infection, it is important to understand their potential toxic effects on human erythrocytes. Therefore, the objective of the current investigation was to elucidate the effects of (Schneider) skin extracts on the physiology of human erythrocytes.

Interlaboratory Evaluation of Enterococcus faecium NRRL B-2354 as a Salmonella Surrogate for Validating Thermal Treatment of Multiple Low-Moisture Foods.

Abstract: This multi-institutional study assessed the efficacy of Enterococcus faecium NRRL B-2354 as a nonpathogenic Salmonella surrogate for thermal processing of nonfat dry milk powder, peanut butter, almond meal, wheat flour, ground black pepper, and date paste. Each product was analyzed by two laboratories (five independent laboratories total), with the lead laboratory inoculating (E. faecium or a five-strain Salmonella enterica serovar cocktail of Agona, Reading, Tennessee, Mbandaka, and Montevideo) and equilibrating the product to the target water activity before shipping.
