The relationship between resistance detected in the faecal egg count reduction test (FECRT) and the lethal dose 50% (LD50) in the egg hatch assay (EHA) for benzimidazoles (BZs) and a larval development assay (LDA) for BZs, levamisole (LEV) and ivermectin (IVM) was examined on 13 sheep farms and 12 goat farms in Denmark. Out of 10 farms where resistance

AbstractThe article describes the results of detection of 50% (ID50) and 100% (ID100) lethal doses of the pathogen in guinea pigs infected with one-day Cl.Oedematiens culture grown in Kitt-Tarottsi nutrient medium from pathological samples from sheep infected with bradzot.

Journal of Toxicology and Environmental Health, 1977
A program for a small digital computer was developed to calculate the median lethal dose (LD50) and its errors. The algorithm employed in the program was based on a method described by Bliss. Modifications introduced by Finney are also discussed. The results indicate a high degree of accuracy compared with calculations performed by Bliss.

Summary Counting of elementary bodies of meningo-pneumonitis virus in dialysed allantoic fluid by electron microscopy is described. Dialysis against distilled water for 18 to 24 hours at 5°C did not alter the lethal potency of the fluid for chick embryos inoculated via the yolk sac.

Journal of Applied Toxicology, 1986
AbstractThe approximiate lethal dose (ALD) to rats following oral administration of nine chemicals was determined. The ALD (lowest dose at which death was produced) for each chemical was used to define the general order of toxicity as being either extremely, highly, moderately, slightly, or practically non‐toxic.

Cofactors such as stress have been suspected to play a role in the susceptibility to opportunistic infections. Toxoplasma gondii is one of the major opportunistic infectious agents in immunocompromised individuals, and infection can be modulated by external factors such as stress.The purpose of this study was to examine the in vivo and in vitro role of
