The ovicidal effect of selected chemicals against eggs of Echinococcus granulosus. 1974

M V Pérez-Esandi, and C W Colli, and P M Schantz

The ovicidal activity of various chemicals against eggs of E. granulosus was evaluated by measuring infectivity to CF(1) mice after exposing the eggs to aqueous solutions of the chemicals for 1 h at room temperature. Significant reductions in infectivity were observed in eggs treated with Lugol's iodine, 0.015% ammonium dodecylbenzenesulfonate, 70% ethanol, or 5% or 10% glutaraldehyde. No cysts developed in 10 mice that received doses of 1 000 eggs treated with 5% glutaraldehyde, and only 1 of 10 mice developed cysts after exposure to eggs treated with 10% glutaraldehyde.

D011196	Potassium Permanganate	Permanganic acid (HMnO4), potassium salt. A highly oxidative, water-soluble compound with purple crystals, and a sweet taste. (From McGraw-Hill Dictionary of Scientific and Technical Information, 4th ed)	Permanganate, Potassium
D004202	Disinfectants	Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed)	Biocide,Disinfectant,Biocides
D004446	Echinococcus	A genus of very small TAPEWORMS, in the family Taeniidae. The adult form is found in various CARNIVORA but not humans. The larval form is seen in humans under certain epidemiologic circumstances.
D005260	Female		Females
D005557	Formaldehyde	A highly reactive aldehyde gas formed by oxidation or incomplete combustion of hydrocarbons. In solution, it has a wide range of uses: in the manufacture of resins and textiles, as a disinfectant, and as a laboratory fixative or preservative. Formaldehyde solution (formalin) is considered a hazardous compound, and its vapor toxic. (From Reynolds, Martindale The Extra Pharmacopoeia, 30th ed, p717)	Formalin,Formol,Methanal,Oxomethane
D005976	Glutaral	One of the protein CROSS-LINKING REAGENTS that is used as a disinfectant for sterilization of heat-sensitive equipment and as a laboratory reagent, especially as a fixative.

D000431	Ethanol	A clear, colorless liquid rapidly absorbed from the gastrointestinal tract and distributed throughout the body. It has bactericidal activity and is used often as a topical disinfectant. It is widely used as a solvent and preservative in pharmaceutical preparations as well as serving as the primary ingredient in ALCOHOLIC BEVERAGES.
