Human and Animal Pathogens Transmitted:
Cochlicella unifasciata can act as an intermediate host the trematode Dicrocoelium dendriticum (Rudolphi) Looss, which could potentially infect humans and other animals.
Cochlicella acuta and C. barbara are known to be intermediate hosts of nematodes and trematodes which infect man and domestic animals. Cochlicella acuta is an intermediate host of both M�llerius capillaris (M�ller) and Cystocaulus ocreatus Davtian, lung worms of sheep. Cochlicella barbara can act as an intermediate host for Protostrongylus rufescens (sheep lungworm).

Method Notes:
Cochlicella barbara (=Prietocella barbara) should be included when surveying for this genus.
Negative data for the genera Cernuella, Cochlicella, and Monacha can be entered at the genus level if no individuals of that genus are found in the sample and if the sampling method used will capture individuals of that genus if they are present in the environment from which that sample was taken. All species of these genera are exotic and not native to the U.S. All positives, regardless of genus, must be reported at the species level; no positive entries at the genus level are allowed.
