Various plant species such as have developed defensive measures, namely, spines, thorns, and other sharp pointed structures to protect themselves from herbivores and other animals feeding on them. has invaded the northern part of Laikipia County, Kenya, and its fruits are protected by small spines called glochids. This study determined the pathology in goats feeding on this plant in Laikipia County. Eighteen goats that had eaten the plant and six others that were raised in a ranch without were purchased for the study. All study animals were clinically examined for lesions and euthanized for necropsy examination. Clinically, goats affected by had poor body condition, wounds on various body parts, and diarrhea. Variable numbers of spines occurred externally on the skin throughout the body and elicited pain, swelling, and ulcerative wounds on affected parts. Internal lesions were observed in subcutaneous tissues (100%), together with stomatitis, cheilitis, gingivitis, glossitis, abomasitis (100%), rumen, reticulum, omasum thinning and loss of papillae (72.2%), esophagitis, and duodenitis (5.6%). Carcasses had gelatinous fat and muscular atrophy. Other gross lesions were generalized viscera atrophy, edema, subcutaneous emphysema, lymphadenopathy, abscesses, ascites, hydrothorax, and hydropericardium. The abomasum wall and its mucosal folds were swollen with edema, haemorrhages, and scattered foci of abscesses. Histopathology confirmed the main lesions in all affected goats were foreign-body granulomas which were located in all organs with gross lesions. Goats from -free ranches had no spines or lesions. The pathological effects caused by resulted in emaciated goats due to pain, inability to masticate and assimilate food, and stress, resulting in poor carcass and organs quality and possible condemnation and death. This could affect the socioeconomics and livelihoods of communities in the study area, and therefore, the spread of this plant needs to be controlled.
各种植物物种，如[此处原文植物名缺失]，已经进化出防御措施，即刺、棘刺和其他尖锐的结构，以保护自己免受食草动物和其他以它们为食的动物的侵害。[此处原文植物名缺失]已经入侵了肯尼亚莱基皮亚县的北部，其果实受到称为倒刺的小刺的保护。本研究确定了在莱基皮亚县以这种植物为食的山羊的病理情况。购买了18只食用过这种植物的山羊和另外6只在没有[此处原文植物名缺失]的牧场饲养的山羊用于研究。对所有研究动物进行临床检查以查看病变情况，并实施安乐死以进行尸检。临床上，受[此处原文植物名缺失]影响的山羊身体状况不佳，身体各部位有伤口，且腹泻。全身皮肤外部出现数量不等的[此处原文植物名缺失]刺，受影响部位引发疼痛、肿胀和溃疡性伤口。在皮下组织观察到内部病变（100%），同时伴有口腔炎、唇炎、牙龈炎、舌炎、皱胃炎（100%）、瘤胃、网胃、瓣胃变薄和乳头消失（72.2%）、食管炎和十二指肠炎症（5.6%）。尸体有胶冻状脂肪和肌肉萎缩。其他大体病变包括全身内脏萎缩、水肿（此处原文“水肿”重复，疑有误）、皮下气肿、淋巴结病、脓肿、腹水、胸腔积水和心包积水。皱胃壁及其黏膜皱襞因水肿、出血和散在的脓肿病灶而肿胀。组织病理学证实，所有受影响山羊的主要病变是异物肉芽肿，其存在于所有有大体病变的器官中。来自没有[此处原文植物名缺失]的牧场的山羊没有刺或病变。[此处原文植物名缺失]造成的病理影响导致山羊消瘦，原因是疼痛、无法咀嚼和消化食物以及应激，从而导致胴体和器官质量不佳，并可能导致被判定不合格和死亡。这可能会影响研究区域社区的社会经济和生计，因此，需要控制这种植物的传播。
