Abstract: Genetic vaccine which comprises plasmid(s) containing genes coding for antigens of enterotoxigenic Escherichia coli (ETEC) strains is disclosed. Additionally, plasmids may consist of multiple copies of the same antigen (i.e. K88 or K99 fimbrial antigen) or multiple antigens (ie. K88 and K99 fimbrial antigens) and genetic adjuvants such as cytokines (IL-2, IL-4 & GM-CSF), costimulatory molecules (CD80 & CD86) or chemokines or immunostimulatory sequences. A method for isolating antibodies from chicken egg yolk for passive immunization of animals, as well as humans to control diarrhoeal diseases using the genetic vaccines is also disclosed.

Abstract: A seat includes first slots therein for drawing air from the vicinity of a toilet rim into the seat. A second slot is disposed at one end of the seat and is in environmental communication with the first slots. The seat includes a sleeve at one end for receiving a tube to become pivotal about the tube. Anchors secure the the tube to a toilet. A tube slot within the tube is configured to align with the second slot when the seat is in a closed position. The sleeve is configured to cover the tube slot when the seat is in an open position. The tube includes an open first end. A duct fits the first end of the tube. A fan connects to the duct and discharges air to a suitable location.
