Hardly sauve and debonair, the cockroach cockroach or roach, name applied to approximately 3,500 species of flat-bodied, oval insects forming the order Blattodea. Cockroaches have long antennae, long legs adapted to running, and a flat extension of the upper body wall that conceals the is a primitive kindof guy that nonetheless has survived more than 350 million years. But the pest may be more sophisticated than it's given credit for, according to University of Cincinnati The University of Cincinnati is a coeducational public research university in Cincinnati, Ohio. Ranked as one of America’s top 25 public research universities and in the top 50 of all American research universities,[2] scientist Richard D. Karp.

In a report in the April TRANSPLANTATION, Karp says theinsect's immune arsenal includes allograft immunity, the process responsible for rejecting transplants from donors of the same species. Previous work at the Cincinnati lab had shown that cockroaches cockroaches insects which may carry Salmonella spp. in their gut and play a part in the spread of the disease. produce antibody-like substances against venom of other insects. The ability to reject grafts, long observed in higher animals, is evidence that the insect also has cell-mediated immunity. |
