We studied the seroprevalence of six reproductive pathogens in Spanish hunter-harvested wild boar females. The sample was representative of the hunting harvest in the studied hunting estates. Mean antibody prevalences were: 60.6+/-0.06% for Aujeszky's disease virus (ADV), 56.6+/-0.09% for porcine parvovirus (PPV), 51.8+/-0.06% for porcine circovirus type 2 (PCV2), 29.7+/-0.09% for Brucella spp. and 36.3+/-0.1% for Toxoplasma gondii. We did not detect antibodies against porcine reproductive and respiratory syndrome virus (PRRSv). ADV seroprevalence was associated with PPV and PCV2 seroprevalence in Spanish wild boar females. Ovulation rate in the studied wild boar females was 4.41+/-0.16 (n=120), mean litter size was 3.91+/-0.16 (n=82) and the partial resorption index 0.92+/-0.17 (n=66). Ovulation rate and litter size were statistically associated with age. T. gondii seroprevalence was negatively related to ovulation rate and partial resorption index. Wild boars from managed fenced estates had antibodies against more pathogens than wild boars from open estates. Potential relations between management of wild boar populations and exposure of individuals to different reproductive pathogens are discussed.
我们研究了西班牙猎人捕获的野生母猪中六种生殖病原体的血清阳性率。该样本代表了所研究狩猎区的狩猎收获情况。平均抗体阳性率分别为：奥耶斯基氏病病毒（ADV）60.6±0.06%，猪细小病毒（PPV）56.6±0.09%，猪圆环病毒2型（PCV2）51.8±0.06%，布鲁氏菌属29.7±0.09%，弓形虫36.3±0.1%。我们未检测到针对猪繁殖与呼吸综合征病毒（PRRSv）的抗体。在西班牙野生母猪中，ADV血清阳性率与PPV和PCV2血清阳性率相关。所研究的野生母猪的排卵率为4.41±0.16（n = 120），平均产仔数为3.91±0.16（n = 82），部分吸收指数为0.92±0.17（n = 66）。排卵率和产仔数与年龄在统计学上相关。弓形虫血清阳性率与排卵率和部分吸收指数呈负相关。来自围栏管理区的野猪比来自开放区的野猪携带更多病原体的抗体。本文讨论了野猪种群管理与个体接触不同生殖病原体之间的潜在关系。
