Biology and Ecology:

Nematodes are aggregated in nodules clustered at the bifurcation of the trachea. Signs of infectionn ara a dry hacking cough,, wheezing and in severe cases inability to breathe deeply (dyspnea) and insufficient oxyben supply to muscles (cyanosis) and emaciation of the host. Infection can be fatal.
