The researchers attribute the gucci shoes relatively high number of cytochrome P450 genes in the Argentine ant to the larger variety of toxins the species encounters in its broad and varied diet. Studying these genes could also help researchers determine if the ants are evolving resistance to pesticides, they said.

When the researchers looked at a family of genes associated with immunity, the Argentine ant genome had a relatively modest count of 90 genes compared with 152 for the fruit fly. This was surprising, they said, given how Argentine ants are packed into crowded, close quarters, and in the case of invasive populations, have a fairly homogeneous gene profile. Such factors are typically conducive to the spread of pathogens gucci outlet, yet the Argentine ant populations have remained robust.

It may be that the Argentine ant has mechanisms to prevent disease that are similar to those of honeybees – which have only 78 comparable immune genes – such as frequent grooming and the quick removal of dead bodies from the colony, the researchers said. They added that genes for anti-microbial chemicals may yet be identified.
