| Edwards' syndrome | <syndrome> There are three instead of the normal two chromosomes 18. Children with this condition have multiple malformations and mental retardation due to the extra chromosome 18. The children characteristically have low birth weight, small head (microcephaly), small jaw (micrognathia), malformations of the heart and kidneys, clenched fists with abnormal finger positioning, and malformed feet. The mental retardation is profound with the iq too low to even test. Nineteen out of 20 (95%) of these children die before their first birthday. The condition is also called edwards syndrome in honor of the british physician and geneticist john edwards who discovered the extra chromosome in 1960. (12 Dec 1998) |

| Edwardsiella | A genus of Gram-negative, facultatively anaerobic bacteria (family Enterobacteriaceae) containing motile, peritrichous, nonencapsulated rods. The type species is Edwardsiella tarda, which is occasionally isolated from the stools of healthy humans and those with diarrhoea, from the blood of humans and other animals, and from human urine. Edwardsiella tarda is an aetiologic agent of gastroenteritis in humans. The two other species in this genus are Edwardsiella hoshinae and Edwardsiella ictaluri. (05 Mar 2000) |
