We examined 1,092 skulls of captive and free-living individuals, representing 33 felid species, to determine the prevalence of focal palatine erosion (FPE). FPE was detected in 3.2% of cats evaluated, including cheetah (Acinonyx jubatus) and 14 other felid species. The prevalence of FPE between cheetah (9.4%; n = 64) and non-cheetah species (2.8%; n = 1,028) (χ(2) test; P = 0.004) and between captive (5.7%; n = 246) and free-living (2.4%; n = 824) individuals (χ(2) test; P = 0.010) were significantly different, with prevalence between captive (19%; n = 21) and free-living (2.9%; n = 34) cheetahs approaching significance (Fisher's exact test; P = 0.064). FPE was diagnosed with equal prevalence in skulls from individuals in which the lower molars did not meet the palatine bone (60.6%) and individuals in which it did (39.4%; n = 33) (χ(2) test; P = 0.139). In cheetahs with FPE, one was a captive animal in Germany, one a free-living cheetah from Mali, one captive cheetah from Kenya, and three captive cheetahs of unknown origin. Additionally, we evaluated the medical records of 49 captive cheetahs in Namibia. Of these cheetahs, 48 (98.0%) had clinical signs consistent with FPE, although only 16 of these 48 (39.6%) had perforation of the palatine bone. Based on physical examinations, FPE was diagnosed in two caracals (Caracal caracal) and one fishing cat (Prionailurus viverrinus) from a North American Zoo. Results from this study confirm FPE in cheetahs outside of Namibia, in a minimum of 15 felid species, and a higher FPE prevalence in captive individuals than free-living ones. Clinical implications of these findings and recommendations for future studies are provided.
我们检查了1092个圈养和自由生活个体的头骨，这些个体代表33种猫科动物，以确定局灶性腭部侵蚀（FPE）的患病率。在接受评估的猫中，有3.2%检测出FPE，包括猎豹（Acinonyx jubatus）和其他14种猫科动物。猎豹（9.4%；n = 64）和非猎豹物种（2.8%；n = 1028）之间FPE的患病率（χ²检验；P = 0.004）以及圈养个体（5.7%；n = 246）和自由生活个体（2.4%；n = 824）之间FPE的患病率（χ²检验；P = 0.010）存在显著差异，圈养猎豹（19%；n = 21）和自由生活猎豹（2.9%；n = 34）之间的患病率接近显著水平（Fisher精确检验；P = 0.064）。在臼齿未与腭骨接触的个体（60.6%）和臼齿与腭骨接触的个体（39.4%；n = 33）的头骨中，FPE的诊断患病率相同（χ²检验；P = 0.139）。在患有FPE的猎豹中，一只来自德国的圈养动物，一只来自马里的自由生活猎豹，一只来自肯尼亚的圈养猎豹，以及三只来源不明的圈养猎豹。此外，我们评估了纳米比亚49只圈养猎豹的病历。在这些猎豹中，48只（98.0%）有与FPE一致的临床症状，尽管这48只中只有16只（39.6%）有腭骨穿孔。根据体格检查，在一只北美动物园的狞猫（Caracal caracal）和一只渔猫（Prionailurus viverrinus）中诊断出FPE。这项研究的结果证实了纳米比亚以外的猎豹中存在FPE，至少在15种猫科动物中存在，并且圈养个体的FPE患病率高于自由生活个体。提供了这些发现的临床意义以及对未来研究的建议。
