三种竹鼠源致病性细菌混合感染病例的组织病理学变化分析

open access: yes野生动物学报, 2021
实验旨在研究竹鼠混合感染致病性大肠杆菌、致病性棒状杆菌和致病性绿色气球菌所引起的组织病理学变化。通过剖检、组织切片、苏木素—伊红(HE)染色及图像观察分析法观察混合感染3种致病性细菌的组织器官的病理及组织病理学变化。结果显示:患病竹鼠下牙脱落,被毛杂乱无光泽,后发现心包有严重无色透明液体、心脏质地柔软凹陷、可见淤血,肝脏表面光滑分布红色细血丝、有明显出血点,肺脏表面可见深红色斑块;脾脏颜色较为暗沉、表面不粗糙、边缘呈锯齿状、肾脏呈大理石色,表面凹凸不平等;心肌细胞胞质疏松淡染肥大细胞浸润;肝索结构不清,

致乌苏里母貉腹泻性疾病病原的检测分析

open access: yes野生动物学报, 2020
为了鉴定乌苏里母貉腹泻性疾病病原,采集患腹泻母貉的肛拭子及粪便样品,通过胶体金试纸条、卵囊分离法、PCR法和细菌分离鉴定等方法对采集的病料进行病原检测。结果显示,犬瘟热病毒、细小病毒、冠状病毒抗原检测为阴性,分离鉴定的病原为钩口线虫和大肠杆菌,通过致病性试验验证其致病性,分离的大肠杆菌对小白鼠具有很强的致病性。引起貉腹泻的病原为钩口线虫和大肠杆菌混合感染,且分离的致病性大肠杆菌对头孢曲松、头孢噻呋、美罗培南、左氧氟沙星4种药物敏感,其他的药物具有不同的耐药性。为貉腹泻病的防控提供研究基础。

火烈鸟腹泻沙门菌分离鉴定、致病性及耐药性检测

open access: yes野生动物学报, 2022
为了分析火烈鸟(Phoenicopterus ruber)腹泻沙门菌(Salmonella)的致病性及耐药性情况,2016—2020年采集动物园中患腹泻火烈鸟的粪便、肛拭子和死亡火烈鸟的肝脏等病料组织102份,采用细菌分离鉴定和PCR方法进行沙门菌鉴定,采用人工感染小白鼠致病性试验和K-B药敏纸片法分别检测分离菌株的致病性和耐药表型情况。结果显示:从102份病料组织中分离得到89株沙门菌,其中75株沙门菌对小白鼠具有致病性,这75株沙门菌分离菌株对链霉素、阿莫西林、氨苄西林等14种药物耐药率在45.3 ...

高致病性禽流感发生风险评估模型的建立

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2008
【目的】 对高致病性禽流感发生的风险进行评估,为该病制定科学有效的控制策略提供理论依据?【方法】 首先,通过对已发生的高致病性禽流感相关资料的分析,结合已有的研究成果,确定高致病性禽流感发生的风险因素;然后通过改进现有对高致病性禽流感发生的风险评估方法---层次分析法,利用改进后的模糊层次分析法确定风险因素的权重;最后应用多指标综合评分法计算出风险概率,建立高致病性禽流感发生风险评估模型?【结果】 将该模型对2008年春季我国各省份禽流感疫情发生情况的风险预警评估结果与今春实际情况进行对照检验 ...

学前儿童对病因及其致病不确定性的认知 [PDF]

open access: yes, 2008
疾病是儿童早期即能接触到的一种生物现象.在日常生活中,他们不仅要学会如何向父母和医生汇报自己的症状,还要学会采取正确的健康行为方式来保持自己的身心健康.儿童对疾病的认知,也直接影响到患儿向医生汇报症状的能力及其对治疗的配合.探讨学前儿童对病因及其致病不确定性的认知,可以使我们进一步了解儿童对疾病的认识水平,从而有针对性地制定相应的教育方案,丰富儿童的疾病和健康知识,帮助儿童保持身心健康.儿童的疾病和健康认知已开始受到关注[1-3]

Radiographic identification and description of the equine middle conchal sinus (ethmoidal sinus): Implications for diagnosing middle conchal sinusitis

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background The middle conchal sinus (MCS) (ethmoidal sinus) remains one of the least understood equine paranasal compartments. Despite recognition of its involvement in sinonasal disease, disorders of the MCS often remain underdiagnosed in the absence of computed tomographic (CT) imaging due to limited anatomical understanding and challenges ...

Regulatory compliance and support for altered management of the exotic pet trade

open access: yesConservation Biology, EarlyView.
Abstract Globally, the exotic pet trade has contributed to species invasion, disease, and animal welfare risks. Although scientists have advocated for increased trade regulation, the success of management and regulatory efforts depends on compliance by participants in the exotic pet trade. We used a regulatory compliance framework to investigate exotic

Titanium Implant Abutments With Polydopamine‐Mesoporous Cerium Dioxide Coatings for Enhanced Antibacterial, Anti‐Inflammatory, and Soft Tissue Integration Properties

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The poor soft tissue integration around titanium implants creates a microgap that serves as a pathway for pathogen invasion, resulting in infection, inflammation, and the progression of peri‐implantitis. As the implant’s transmucosal component, the abutment determines the degree of peri‐implant soft tissue attachment.
