Exclusion of Horizontal and Vertical Transmission as Major Sources of Infections in a Breeding Colony of Rhesus Macaques ().

The vector-borne protozoal parasite causes Chagas disease in humans and animals. This parasite is endemic to the southern United States where outdoor-housed NHP at biomedical facilities are at risk of infection. In addi- tion to the direct morbidity caused by , infected animals are of limited biomedical research use because infections can produce confounding pathophysiologic changes even in animals with no clinical disease.

The clinical effects of a low dose dexmedetomidine constant rate infusion in isoflurane anesthetized cats.

The aim of this study was to evaluate the effects of a low dose dexmedetomidine constant rate infusion (CRI) on cardiopulmonary function, inhalant anesthetic concentration and recovery in isoflurane anesthetized cats. In a prospective, randomized, blinded, controlled design, 12 cats undergoing anesthesia for ovariohysterectomy were administered hydromorphone (0.1mg/kg) intramuscularly, propofol (4.

Imported malaria in Germany in 1996.

Malaria is not endemic in Germany, but it is one of the most commonly imported infectious diseases. The numbers of imported cases increased from 1994 to 1996; in 1997 according to preliminary data there were a total of 994 cases. In 1996, 1021 cases of ma

[Worldwide eradication of poliomyelitis].

Poliomyelitis, an infectious disease with acute and persistent flaccid paralysis is caused by poliovirus (types 1, 2 or 3), an enterovirus. The infection is asymptomatic in 95% of infected subjects. Most of the paralytic cases occur in adolescents or adults in the course of polio type 1 infection.
