We examined the role of serum, complement and the reticuloendothelial system in mouse resistance to type III group B streptococci (GBS). Normal serum obtained from 21 day-old mice failed to protect chick embryos against a lethal intravenous (IV) inoculation of GBS-III-SS620/50. Mice that were decomplemented using cobra venom factor remained resistant to intraperitoneal (IP) inoculation of 10(6) colony-forming units (CFU) of GBS-III-22620/50, GBS III-Bell and GBS-III-Minnesota. In contrast, mice prepared with IP oleic acid were killed with 10(4) CFU of GBS-III-SS620/50 IP. However, when mice were injected IV with oleic acid, they remained resistant to IP inoculation of GBS-III-SS620/50. These results suggest that peritoneal macrophages play a role in murine defense against IP infection with GBS-III-SS620/50.

D002642 Chick Embryo The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching. Embryo, Chick,Chick Embryos,Embryos, Chick
D004546 Elapid Venoms Venoms from snakes of the family Elapidae, including cobras, kraits, mambas, coral, tiger, and Australian snakes. The venoms contain polypeptide toxins of various kinds, cytolytic, hemolytic, and neurotoxic factors, but fewer enzymes than viper or crotalid venoms. Many of the toxins have been characterized.
