The presence of Clostridium perfringens Type E iota toxin was confirmed from the cecal contents of 23 of 46 rabbits which died of enteritis complex. The most consistent lesions observed were hemorrhage and edema in the cecum. Rabbit toxicity tests showed the toxic cecal contents were lethal for young rabbits unless incubated with Clostridium perfringens Type E antiserum.
The prototype is described of a baby incubator, designed to be manufactured and used in Ghana, but of high enough quality to complete directly with imported models. A novel design is used, in which the usual all-round hood, with a sealed control unit underneath it, is replaced by a one-sided configuration, with the control system built into the back. It is much easier to manufacture, but still allows good access and temperature control.
