摘要 我们使用行为、生理和寄生虫学措施来记录急性疟疾感染对实验感染幼年 Apapane (Himatione sanguinea) 活动预算的影响。八只鸟中的五只在被感染性蚊虫叮咬后 20 至 32 天内死亡。受感染的阿帕帕内花在飞行、行走或跳跃等运动活动以及唱歌、梳理毛发、进食和探查等静止活动上的时间较少。坐着的时间与寄生虫血症呈正相关，并且在感染后以及治疗组和对照组之间急剧增加。死于感染的鸟类体重和皮下脂肪显着减少，而幸存的阿帕烷能够更好地维持身体状况和脂肪水平。当初次感染后五个月再次受到寄生虫攻击时，幸存的鸟类的寄生虫血症没有增加，这表明它们已经对再次感染产生了免疫力。无论结果如何，受感染的鸟类都会经历急性疾病，导致它们无法在野外觅食或逃脱捕食者。
Abstract We used behavioral, physiological, and parasitological measures to document effects of acute malarial infections on activity budgets of experimentally infected juvenile Apapane (Himatione sanguinea). Five of eight birds died within 20 to 32 days after exposure to a single infective mosquito bite. Infected Apapane devoted less time to locomotory activities involving flight, walking or hopping, and stationary activities such as singing, preening, feeding, and probing. The amount of time spent sitting was positively correlated with parasitemia and increased dramatically after infection and between treatment and control groups. Birds that succumbed to infection experienced a significant loss of body mass and subcutaneous fat, whereas surviving Apapane were better able to maintain body condition and fat levels. When rechallenged with the parasite five months after initial infection, surviving birds experienced no increase in parasitemia, indicating that they had become immune to reinfection. Regardless of the outcome, infected birds experienced acute illness that would have left them unable to forage or to escape from predators in the wild.
