They do not produce eggs; instead the adults produce larvae that are ready to infect as soon as they leave their mother's womb. ''C. penneri'' is found only in Mexico. ==Transmission== Unlike most nematodes, which infect their host by being accidentally swallowed, ''C. penneri'' is acquired through sexual transmission. In lizards, it is passed through the cloaca of the infected lizard to the cloaca of the other during mating, and it has been found, through experiments, that female contraction is 100% percent, while male contraction is about 70%. In an experiment by the Department of Biology at Florida Southern College, the researchers found that land snails and crickets do not serve as transport or intermediate hosts, which supports the idea that ''C. penneri'' is transferred only during sexual intercourse of the definitive host. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cyrtosomum penneri」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
