Toys in the Playrooms of Children's Hospitals: A Potential Source of Nosocomial Bacterial Infections?

Pediatric patients are more susceptible and vulnerable to nosocomial infections, in part because of their nascent and developing immune system and in part due to certain congenital conditions. Consequently, we found limited literature that investigated and reported children's toys in hospital playrooms as potential reservoirs of pathogenic microbes. Hence, in the present study, we aimed to investigate toys as potential vectors for nosocomial infections in children's hospitals.

Comparative Immunogenicity in Rabbits of the Polypeptides Encoded by the 5' Terminus of Hepatitis C Virus RNA.

Recent studies on the primate protection from HCV infection stressed the importance of immune response against structural viral proteins. Strong immune response against nucleocapsid (core) protein was difficult to achieve, requesting further experimentation in large animals. Here, we analyzed the immunogenicity of core aa 1-173, 1-152, and 147-191 and of its main alternative reading frame product F-protein in rabbits.

[The effect of mechanical loads on the surface state of denture steel].

Studies of the mechanical properties and electron microscopic examination of 12X18H9T steel surface in dentures have revealed their changes after mechanical load. Complex corrosive destruction of dentures in the oral cavity is regarded as stress corrosion.
