A Simulation Study to Evaluate Improvements in Anesthesia Work Environment Contamination After Implementation of an Infection Prevention Bundle.

Background: Microbiological contamination of the anesthesia work environment (AWE) is a potential source of health care-associated infections. Medication syringes, stopcocks, and many other areas are routinely contaminated during anesthetic care, and adherence to hand hygiene recommendations is poor. Using a simulation model, we investigated whether AWE contamination could be reduced by implementing an intervention bundle focused on infection prevention.

Social structure of the mara (Dolichotis patagonum) as a determinant of gastro-intestinal parasitism.

A one-year study of gastro-intestinal parasitism in a free-ranging population of maras at Whipsnade Wild Animal Park, UK, revealed a strong relationship between membership of social units and both intensity and prevalence of infection. The mara, a hystricomorph rodent from southern Argentina, has a social organization including both monogamy and communal denning of the young, an apparently unique combination among mammals. From October 1992 to September 1993, strongyloid parasite loads were estimated from faecal egg counts.

Use of intrauterine devices as a means of contraception in a colony of chimpanzees (Pan troglodytes).

The uncontrolled reproduction of the captive chimpanzee colony at the Primate Centre, CIRMF, Gabon, has led to high neonatal mortality. The only solution meeting ethical, financial, and practical considerations was to attempt reversible physical contraception using intrauterine devices (IUDs). Human IUDs were inserted into 21 females of various ages, parities, and stages of the menstrual cycle.
