Three troops of olive baboons (Papio anubis) comprising 134 animals were captured during a translocation program. All three troops (PHG, CRIP, WBY) lived in high-altitude savannah, but two (CRIP and WBY) also frequented human settlements, where they had access to the garbage pits and vegetable gardens. The translocation offered the opportunity to compare body condition, activity patterns, and parasitism among the troops of animals. A variety of body measurements were taken, a physical examination performed, activity patterns for the previous 2 years enumerated, and blood and feces collected for virological and parasitological analyses. Body condition, as judged qualitatively by appearance and quantitatively by subcutaneous fat thickness and body weight, was lowest in PHG, the naturally foraging troop. All animals were negative for all viruses. No blood-borne parasites were found, but the feces of the majority of animals were positive for eggs of strongyles, ascarids, Trichuris spp., and Strongyloides spp. Quantification of strongyles indicated the heaviest burdens were in the non provisioned troop PHG. These results when combined with the behavioral observations that PHG spent more time foraging and less time resting or socializing than WBY suggest lowered availability and/or a poorer quality of PHG's diet. The data support the hypothesis of a causal relationship between host nutrition and helminth parasite infection but do not permit general conclusions to be drawn on mechanisms of interaction.
在一次转移计划中捕获了由134只动物组成的三群东非狒狒（埃及狒狒）。所有三群（PHG、CRIP、WBY）都生活在高海拔稀树草原，但其中两群（CRIP和WBY）也经常出没于人类住区，在那里它们可以进入垃圾坑和菜园。这次转移提供了一个机会来比较各群动物的身体状况、活动模式和寄生虫感染情况。进行了各种身体测量，进行了体格检查，列举了过去两年的活动模式，并采集了血液和粪便用于病毒学和寄生虫学分析。通过外观定性判断以及通过皮下脂肪厚度和体重定量判断，自然觅食的PHG群动物的身体状况最差。所有动物的所有病毒检测均为阴性。未发现血源寄生虫，但大多数动物的粪便中圆线虫、蛔虫、鞭虫和类圆线虫虫卵呈阳性。圆线虫的定量分析表明，未获得食物供应的PHG群动物的感染负担最重。这些结果与行为观察结果相结合，即PHG群比WBY群花费更多时间觅食，休息或社交时间更少，这表明PHG群的食物供应减少和/或食物质量较差。数据支持宿主营养与蠕虫寄生虫感染之间存在因果关系的假设，但不允许就相互作用机制得出一般性结论。
