We collected 153 northern bobwhites (Colinus virginianus) over a 10-mo period from Tall Timbers Research Station near Tallahassee, Florida, USA. Five species of gastrointestinal helminths were encountered commonly (greater than 30% prevalence): Cyrnea colini, Raillietina cesticillus, R. colinia, Heterakis isolonche, and Trichostrongylus tenuis. Other helminths included Brachylaima sp., Rhabdometra odiosa, Mediorhynchus papillosis, Cheilospirura spinosa, Dispharynx nasuta, Gongylonema ingluvicola, and Tetrameres pattersoni. During the intervening 15 yr since the last year-round study of this population of birds, C. spinosa and T. pattersoni have declined markedly, and Strongyloides sp. probably has become extinct locally. Prevalence and intensity seem more likely to fluctuate in parasite species that have complex life cycles.
我们在美国佛罗里达州塔拉哈西附近的高大木材研究站，于10个月的时间里收集了153只北美鹑（Colinus virginianus）。常见5种胃肠道蠕虫（感染率超过30%）：柯氏嗜气管线虫（Cyrnea colini）、鸡瑞利绦虫（Raillietina cesticillus）、柯氏瑞利绦虫（R. colinia）、孤立异刺线虫（Heterakis isolonche）和纤细毛圆线虫（Trichostrongylus tenuis）。其他蠕虫包括短咽属吸虫（Brachylaima sp.）、可恶瘤吻绦虫（Rhabdometra odiosa）、乳头中吻绦虫（Mediorhynchus papillosis）、具刺唇旋线虫（Cheilospirura spinosa）、鼻分咽线虫（Dispharynx nasuta）、嗉囊筒线虫（Gongylonema ingluvicola）和派氏四棱线虫（Tetrameres pattersoni）。自上次对该鸟类种群进行全年研究后的15年间，具刺唇旋线虫和派氏四棱线虫显著减少，类圆线虫属（Strongyloides sp.）可能已在当地灭绝。具有复杂生命周期的寄生虫种类，其感染率和感染强度似乎更易波动。
