    背景:传统医学(TM)干预措施是针对新兴和地方性人畜共患疾病的传统医学干预措施的合理治疗替代方案,特别是在可能缺乏资源和基础设施的中低收入国家。尽管TM干预的使用越来越受欢迎,它们的临床安全性和有效性在许多国家的传统医疗保健中仍然存在争议。
    方法:我们对同行评审的文献进行了范围审查,该文献综合并绘制了TM干预措施在印度次大陆治疗和预防人畜共患病的证据。该地区,生物多样性和新出现的感染的全球热点,其特征在于TM使用的高流行率。基于科学文献(主要是案例研究,n=l06项研究),我们的评论(1)绘制了文献的范围,(2)综合了TM干预对人畜共患病的应用证据,(3)批判性地反映TM的状况,并确定未来研究重点的领域。
    结果:证据综合证实了TM干预对次大陆人畜共患病的广泛使用,大部分研究来自印度(n=99研究,93.4%),其次是巴基斯坦(n=3项研究,2.8%),孟加拉国(n=2项研究,1.9%),和斯里兰卡(n=1,0.9%)。大多数综述的研究报告了植物物种的民族药用,主要用于治疗登革热(n=20项研究),结核病(n=18项研究),大肠杆菌感染(n=16项研究),淋巴丝虫病和霍乱(n=9个)。然而,关于这些报告的TM干预措施的安全性和有效性的证据是有限的,这表明这些数据很少在同行评审的文献中收集和/或共享。
    结论:因此,这篇综述强调,虽然TM已经被使用,并且可以提供更广泛的干预措施来对抗新兴和地方性人畜共患病和外寄生虫,迫切需要对这些干预措施的安全性和有效性进行严格的临床试验和验证.
    BACKGROUND: Traditional medicine (TM) interventions are plausible therapeutic alternatives to conventional medical interventions against emerging and endemic zoonotic diseases, particularly in low-and middle-income countries that may lack resources and infrastructure. Despite the growing popularity in the usage of TM interventions, their clinical safety and effectiveness are still contested within conventional healthcare in many countries.
    METHODS: We conducted a scoping review of the peer-reviewed literature that synthesises and maps the evidence on TM interventions for the treatment and prevention of zoonoses on the Indian subcontinent. The region, a global hotspot of biodiversity and emerging infections, is characterised by high prevalence of TM use. Based on the scientific literature (mostly case study research, n=l06 studies), our review (1) maps the scope of the literature, (2) synthesises the evidence on the application of TM interventions for zoonoses, and (3) critically reflects on the state of TM and identifies areas for future research focus.
    RESULTS: The evidence synthesis confirmed widespread usage of TM interventions for zoonoses on the subcontinent, with the majority of research reported from India (n=99 studies, 93.4%), followed by Pakistan (n=3 studies, 2.8%), Bangladesh (n=2 studies, 1.9%), and Sri Lanka (n=1, 0.9%). Most of the reviewed studies reported on ethno-medicinal uses of plant species, primarily for treating dengue (n=20 studies), tuberculosis (n=18 studies), Escherichia coli infection (n=16 studies), lymphatic filariasis and cholera (n=9 apiece). However, the evidence on the safety and effectiveness of these reported TM interventions is limited, indicating that these data are rarely collected and/or shared within the peer-reviewed literature.
    CONCLUSIONS: This review thus highlights that, whilst TMs are already being used and could offer more widely accessible interventions against emerging and endemic zoonoses and ectoparasites, there is an urgent need for rigorous clinical testing and validation of the safety and effectiveness of these interventions.

    该研究的重点是欧洲休养鹿(Damadama)的狩猎实践和潜在致病细菌种类。在五年内,检查了罗马尼亚西部的三个猎场。在此期间,共猎杀了1881头鹿,通过直肠和鼻拭子从120具尸体中收集了240个样本。利用细菌学测定和Vitek®2紧凑型系统鉴定细菌菌株。值得注意的是,Socodor狩猎场在雄鹿(M组)和幼鸟(F组)之间的收获配额上表现出显著差异,有利于后者。在基利内乌克里希-萨利泰卡狩猎场,观察到两组之间的收获配额可能存在相关性.鉴定出的潜在致病菌为大肠杆菌,沙门氏菌属。,金黄色葡萄球菌,单核细胞增生李斯特菌和屎肠球菌。这些结果突出了有效管理鹿种群的重要性,并认识到DamaDama传播人畜共患病原体的潜力,强调采用“一个健康”方法并保持对该游戏物种种群动态的持续监视的必要性。
    The study focused on the hunting practices and potentially pathogenic bacterial species among European fallow deer (Dama dama). Within a five-year period, three hunting grounds from Western Romania were examined. During this period, a total of 1881 deer were hunted, and 240 samples were collected by rectal and nasal swabbing from 120 carcasses. Bacterial strains were identified utilizing bacteriological assays and the Vitek® 2 Compact system. Notably, the Socodor hunting ground exhibited a significant difference in harvesting quotas between the bucks (Group M) and does/yearlings (Group F), favoring the latter. In the Chișineu Criș-Sălișteanca hunting ground, a likely correlation in harvesting quotas between the two groups was observed. The identified potentially pathogenic bacteria were Escherichia coli, Salmonella spp., Staphylococcus aureus, Listeria monocytogenes and Enterococcus faecium. These results highlight the importance of effectively managing the deer population and recognize the potential for Dama dama to spread zoonotic pathogens, emphasizing the necessity of adopting a One Health approach and maintaining ongoing surveillance of this game species\' population dynamics.

    Cetaceans, which are crucial in marine ecosystems, act as sentinels for ecosystem and human-environmental health. However, emerging fungal infections, particularly by Candida spp., pose a growing concern in these marine mammals. This review consolidates current knowledge on the prevalence, clinical manifestations, species distribution, and antifungal resistance of Candida infections in cetaceans. We detail the diverse pathogenic impacts of Candida, including respiratory, dermal, and systemic afflictions, underscoring diagnostic and treatment challenges amid rising antifungal resistance. Our analysis extends beyond health concerns in captive cetaceans, where confinement stress heightens vulnerability, to encompass substantial ecological risks in wild populations. The review emphasizes the One Health perspective, linking cetacean health with broader environmental and human public health issues. We particularly focus on the potential zoonotic transmission of emerging fungal pathogens such as Candida auris and the role of environmental changes in fostering antifungal resistance. The study underscores the need for concerted, interdisciplinary efforts in veterinary, medical, and environmental sciences to enhance understanding and management of Candida infections in cetaceans. We advocate for comprehensive monitoring and collaborative research initiatives to mitigate the rising challenge of these infections. Addressing Candida spp. in cetaceans is not just a conservation priority but a critical step in safeguarding overall marine health and, by extension, human health in the context of evolving infectious diseases.

    Zoonoses, diseases transmitted from animals to humans, continue to challenge public health despite advancements in controlling infectious diseases. The intricate link between human, animal, and environmental health is emphasised by the fact that zoonoses contribute to 60% of emerging human infections. Wet markets, wildlife hunting, intensive wildlife farming, and interactions between domestic animals and humans are key transmission sources. Historical examples like the bubonic plague and English Sweats illustrate the longstanding impact of zoonotic diseases. With new transmission patterns emerging, it is necessary to use new techniques to predict disease spread. This article delves into the emergence of new zoonoses, such as the Nipah virus and the SARS-CoV-2 pandemic, emphasizing the importance of understanding zoonotic aspects for outbreak prevention. Re-emerging zoonoses, like tuberculosis and vaccine-preventable diseases, present challenges, exacerbated by factors like globalized human activities and disruptions caused by the COVID-19 pandemic. Public health implications are explored, including economic losses, antibiotic resistance, and the disruption of international trade.
    Choroby odzwierzęce, choroby przenoszone ze zwierząt na ludzi, w dalszym ciągu stanowią wyzwanie dla zdrowia publicznego pomimo postępów w zwalczaniu chorób zakaźnych. Skomplikowany związek między zdrowiem ludzi, zwierząt i środowiskiem podkreśla fakt, że choroby odzwierzęce są przyczyną 60% nowo pojawiających się infekcji u ludzi. Kluczowymi źródłami przenoszenia są mokre targi, polowania na dziką zwierzynę, intensywna hodowla dzikich zwierząt oraz interakcje między zwierzętami domowymi a ludźmi. Historyczne przykłady, takie jak dżuma i poty angielskie, ilustrują długotrwały wpływ chorób odzwierzęcych. W miarę pojawiania się nowych wzorców przenoszenia konieczne jest stosowanie nowych technik przewidywania rozprzestrzeniania się choroby. W artykule omówiono pojawienie się nowych chorób odzwierzęcych, takich jak wirus Nipah i pandemia SARS-CoV-2, podkreślając znaczenie zrozumienia aspektów odzwierzęcych w zapobieganiu epidemiom. Ponowne pojawienie się chorób odzwierzęcych, takich jak gruźlica i choroby, którym można zapobiegać poprzez szczepienia, stwarza wyzwania, które dodatkowo pogłębiają takie czynniki, jak globalna działalność człowieka i zakłócenia spowodowane pandemią Covid-19. Badane są skutki dla zdrowia publicznego, w tym straty gospodarcze, oporność na antybiotyki i zakłócenia w handlu międzynarodowym.

    人与狗之间的纽带是珍贵的,自古以来就被珍惜。养狗与许多健康益处有关,如增加体力活动和社会功能,减少抑郁和心血管事件。然而,狗可以将人畜共患疾病传播给人类,其中许多存在皮肤发现。这篇综述总结了皮肤病学表现,传输路线,诊断,和治疗由狗传播的人畜共患疾病,包括媒介传播,细菌,病毒,真菌,和寄生虫感染。这篇综述强调了当患者出现不明原因的皮疹时,临床医生获得全面暴露史的重要性。这种方法可以提供与诊断由宠物狗传播的人畜共患疾病有关的有价值的流行病学线索。此外,确定狗为感染源和随后的兽医治疗可以帮助防止皮肤科患者的复发性感染。
    The bond between humans and dogs is precious and has been treasured since ancient times. Dog ownership is linked to numerous health benefits, such as increased physical activity and social functioning and decreased depression and cardiovascular events. However, dogs can transmit zoonotic diseases to humans, many of which present with cutaneous findings. This review summarizes the dermatologic manifestations, transmission routes, diagnosis, and treatment of zoonotic diseases transmitted by dogs, including vector-borne, bacterial, viral, fungal, and parasitic infections. This review emphasizes the significance of clinicians obtaining a comprehensive exposure history when patients exhibit a rash of unknown origin. Such an approach can provide valuable epidemiological clues related to diagnosing a zoonotic disease transmitted by a pet dog. Furthermore, identifying the dog as an infection source and subsequent veterinary treatment can help prevent recurrent infections in dermatologic patients.

    在低收入和中等收入国家中,人畜共患溢出事件和病毒突变的频率越来越高,这给全球卫生带来了严峻的挑战。促成因素包括食用丛林肉等文化习俗,野生动物传统医药贸易,栖息地破坏,以及贫困定居点对自然栖息地的侵蚀。许多发展中国家现有的“疫苗缺口”通过允许不受控制的病毒复制和新型突变病毒的出现而加剧了这种情况。尽管全球卫生政策解决了人畜共患疾病出现的根本原因,严重缺乏以预防为导向的具体举措,对弱势群体构成潜在风险。这篇文章是针对政策制定者,公共卫生专业人员,研究人员,和全球卫生利益相关者,特别是那些在低收入和中等收入国家从事人畜共患疾病预防和控制的人。本文强调了在动物-人类界面评估潜在的人畜共患疾病并理解导致溢出事件的历史因素的重要性。为了弥合政策差距,提出了包括教育在内的综合战略,合作,专门工作队,环境采样,建立综合诊断实验室。这些策略提倡简单和统一,打破障碍,并将人类置于应对全球卫生挑战的最前沿。面对新出现的人畜共患威胁,这种战略和精神上的转变对于构建一个更具弹性和公平的世界至关重要。
    The increasing frequency of zoonotic spillover events and viral mutations in low and middle-income countries presents a critical global health challenge. Contributing factors encompass cultural practices like bushmeat consumption, wildlife trade for traditional medicine, habitat disruption, and the encroachment of impoverished settlements onto natural habitats. The existing \"vaccine gap\" in many developing countries exacerbates the situation by allowing unchecked viral replication and the emergence of novel mutant viruses. Despite global health policies addressing the root causes of zoonotic disease emergence, there is a significant absence of concrete prevention-oriented initiatives, posing a potential risk to vulnerable populations. This article is targeted at policymakers, public health professionals, researchers, and global health stakeholders, particularly those engaged in zoonotic disease prevention and control in low and middle-income countries. The article underscores the importance of assessing potential zoonotic diseases at the animal-human interface and comprehending historical factors contributing to spillover events. To bridge policy gaps, comprehensive strategies are proposed that include education, collaborations, specialized task forces, environmental sampling, and the establishment of integrated diagnostic laboratories. These strategies advocate simplicity and unity, breaking down barriers, and placing humanity at the forefront of addressing global health challenges. Such a strategic and mental shift is crucial for constructing a more resilient and equitable world in the face of emerging zoonotic threats.

    背景:巴顿病,由巴尔通体属细菌引起的,是一种具有几种哺乳动物水库宿主的人畜共患疾病。在索马里,一个严重依赖牲畜的国家,人畜共患疾病对公共卫生和经济构成重大挑战。据我们所知,尚未进行旨在验证Bartonellaspp的发生的研究。在索马里。本研究调查了单峰动物(Camelusdromedarius,Linnaeus,1758),牛,绵羊,和来自索马里的山羊。
    方法:从各种动物中收集了530份血液样本(155只单支,199山羊,131头牛,和45只羊)在贝纳迪尔和下谢贝利地区。提取DNA进行分子分析,并采用针对NADH脱氢酶γ亚基(nuoG)基因的qPCR方法进行巴尔通体筛查。阳性样品还进行了针对七个分子标记的PCR测定,包括:nuoG,柠檬酸合酶基因(gltA),RNA聚合酶β亚基基因(rpoB),核黄素合酶基因(ribC),60kDa热休克蛋白基因(groEL),细胞分裂蛋白基因(ftsZ),和pap31和qPCR靶向16-23SrRNA内部转录间隔区(ITS),然后进行Sanger测序,BLASTn和系统发育分析。
    结果:在530只测试动物中,5.1%的巴尔通体阳性。通过nuoGqPCR分析。山羊表现出最高的巴尔通体发生率(17/199,8.5%),其次是绵羊(6/44,6.8%),牛(4/131,3.1%),单升(1/155,1.9%)。山羊,绵羊,牛的感染几率高于单峰病。在nuoGqPCR阳性样本中,11.1%,14.8%,11.1%,25.9%的人在基于nuoG的PCR检测中呈阳性,gltA,还有pap31基因,在基于ITS区域的qPCR中,分别。另一方面,nuoGqPCR阳性样品在靶向ribC的PCR检测中呈阴性,rpoB,ftsZ,和GroEL基因。虽然在牛(nuoG和ITS)和山羊(gltA)中检测到牛巴尔通体序列,在单度中检测到了汉氏巴尔通体ITS序列,山羊,和羊。系统发育分析将来自山羊的gltABartonella序列置于牛芽孢杆菌的同一进化枝中。
    结论:本研究显示,第一次,巴尔通体的分子证据。来自索马里的单峰动物和反刍动物以及全球绵羊和山羊中的汉斯尔科。这些发现为巴尔通菌提供了宝贵的见解。发生在索马里牲畜中,强调需要在“一个健康”方法下采取全面的监测和控制措施。
    BACKGROUND: Bartonellosis, caused by bacteria of the genus Bartonella, is a zoonotic disease with several mammalian reservoir hosts. In Somalia, a country heavily reliant on livestock, zoonotic diseases pose significant public health and economic challenges. To the best of our knowledge, no study has been performed aiming to verify the occurrence of Bartonella spp. in Somalia. This study investigated the occurrence and molecular characterization of Bartonella in dromedary (Camelus dromedarius, Linnaeus, 1758), cattle, sheep, and goats from Somalia.
    METHODS: 530 blood samples were collected from various animals (155 dromedary, 199 goat, 131 cattle, and 45 sheep) in Benadir and Lower Shabelle regions. DNA was extracted for molecular analysis, and a qPCR assay targeting the NADH dehydrogenase gamma subunit (nuoG) gene was used for Bartonella screening. Positive samples were also subjected to PCR assays targeting seven molecular markers including: nuoG, citrate synthase gene (gltA), RNA polymerase beta-subunit gene (rpoB), riboflavin synthase gene (ribC), 60 kDa heat-shock protein gene (groEL), cell division protein gene (ftsZ), and pap31 and qPCR targeting the 16-23S rRNA internal transcribed spacer (ITS) followed by Sanger sequencing, BLASTn and phylogenetic analysis.
    RESULTS: Out of 530 tested animals, 5.1% were positive for Bartonella spp. by the nuoG qPCR assay. Goats showed the highest Bartonella occurrence (17/199, 8.5%), followed by sheep (6/44, 6.8%), cattle (4/131, 3.1%), and dromedary (1/155, 1.9%). Goats, sheep, and cattle had higher odds of infection compared to dromedary. Among nuoG qPCR-positive samples, 11.1%, 14.8%, 11.1%, and 25.9% were positive in PCR assays based on nuoG, gltA, and pap31 genes, and in the qPCR based on the ITS region, respectively. On the other hand, nuoG qPCR-positive samples were negative in the PCR assays targeting the ribC, rpoB, ftsZ, and groEL genes. While Bartonella bovis sequences were detected in cattle (nuoG and ITS) and goats (gltA), Bartonella henselae ITS sequences were detected in dromedary, goat, and sheep. Phylogenetic analysis placed gltA Bartonella sequence from a goat in the same clade of B. bovis.
    CONCLUSIONS: The present study showed, for the first time, molecular evidence of Bartonella spp. in dromedary and ruminants from Somalia and B. henselae in sheep and goats globally. These findings contribute valuable insights into Bartonella spp. occurrence in Somali livestock, highlighting the need for comprehensive surveillance and control measures under the One Health approach.

    钩端螺旋体病是一种被忽视的细菌性人畜共患病,影响范围广泛的哺乳动物,从一个健康的角度来看具有重要意义。在过去的几年中,猫钩端螺旋体病在科学界引起了越来越多的关注。在这里,我们描述了遵循PRISMA指南的荟萃分析的系统综述,还有一个额外的PROSPERO注册。该研究提供了全球血清阳性,排尿率,全球血清群分布,从猫中分离出的钩端螺旋体的描述性数据以及有症状的急性疾病猫的临床和实验室特征。搜索是在六个不同的数据库中进行的,有79份报告描述了猫的钩端螺旋体感染。血清反应性猫的合并频率为11%(95%CI:9%-13%),Javanica和Pomona是最常见的血清群。排尿频率为8%(95%CI:5%-10%),在大多数样本中都发现了L.从猫中分离出16株,Bataviae是最常见的血清群。鉴定出20只确认有钩端螺旋体感染的有症状的猫。厌食症,嗜睡,多饮,出血性疾病是最常见的临床体征.结果表明,来自某些地方的猫暴露于钩端螺旋体,并可能充当该病原体的尿液脱落者,因此表明该物种在疾病传播中的可能作用。临床数据表明,与狗相比,急性感染大多不典型,由于难以定义猫的典型临床表现,猫钩端螺旋体病很可能是该物种的未诊断疾病。
    Leptospirosis is a neglected bacterial zoonosis that affects a wide range of mammals, with important implications from a One Health perspective. Over the past years feline leptospirosis has gained increased attention in the scientific community. Here we describe a systematic review with meta-analysis that followed the PRISMA guidelines, with an additional PROSPERO registration. The study provides global seropositivity, urinary shedding rates, global serogroup distribution, descriptive data of leptospires that had been isolated from cats and clinical and laboratory features presented by symptomatic cats with acute disease. The search was carried out in six different databases, with the identification of 79 reports describing leptospiral infection in cats. The pooled frequency of seroreactive cats was 11% (95% CI: 9%-13%), with Javanica and Pomona as the most frequent serogroups found. Frequency for urinary shedding was 8% (95% CI: 5%-10%), with L. interrogans identified in most samples. A total of 16 isolates were isolated from cats, with Bataviae as the most frequent serogroup. Twenty symptomatic cats with confirmed leptospiral infection were identified. Anorexia, lethargy, polydipsia, and bleeding disorders were the clinical signs most frequently reported. The results suggest that cats from some locations are exposed to leptospires and may act as urinary shedders of this pathogen, thus indicating a possible role of this species in disease transmission. Clinical data indicates that acute infection is mostly atypical when compared to dogs, and due to difficulties to define an archetypal clinical presentation in cats, feline leptospirosis is likely to be underdiagnosed disease in this species.

    大量研究表明,随着农业的兴起,关于人类与动物传染病库之间的接触,祖先环境与条件之间存在进化上的不匹配。基于这个进化不匹配框架,我们检查了视觉注意力是否对动物目标致病性表现出适应性调整。与我们的预测一致,与人畜共患传染病的动物媒介相比,带有启发式感染线索的面孔受到了更大的关注。此外,结果表明,注意力对处理存在传染病的面部线索表现出专门的警惕,而它在动物疾病载体和与疾病无关的动物之间进行了比较分配。另一方面,用于放大参与者背景水平的抗病原体动机的病原体显着性操纵并未调节注意力资源的选择性分配。视觉注意力似乎不足以检测和编码动物的人畜共患传播风险,这一事实支持了这样一种观点,即我们进化的疾病避免机制在对抗源自人畜共患新发传染病的全球爆发方面可能效果有限。
    A considerable amount of research has revealed that there exists an evolutionary mismatch between ancestral environments and conditions following the rise of agriculture regarding the contact between humans and animal reservoirs of infectious diseases. Based on this evolutionary mismatch framework, we examined whether visual attention exhibits adaptive attunement toward animal targets\' pathogenicity. Consistent with our predictions, faces bearing heuristic infection cues held attention to a greater extent than did animal vectors of zoonotic infectious diseases. Moreover, the results indicated that attention showed a specialized vigilance toward processing facial cues connoting the presence of infectious diseases, whereas it was allocated comparably between animal disease vectors and disease-irrelevant animals. On the other hand, the pathogen salience manipulation employed to amplify the participants\' contextual-level anti-pathogen motives did not moderate the selective allocation of attentional resources. The fact that visual attention seems poorly equipped to detect and encode animals\' zoonotic transmission risk supports the idea that our evolved disease avoidance mechanisms might have limited effectiveness in combating global outbreaks originating from zoonotic emerging infectious diseases.
