In recent years, the prevalence of brucellosis in animals and humans has been increasing in China despite the considerable efforts taken to date. Dynamic model serves as an influential and promising approach for offering guidance and recommendations for the prevention and control of the disease. At this pivotal moment, it is time to provide a comprehensive and timely examination of the existing achievements derived from the mathematical dynamical modeling studies, highlight the key development trends, delve into identifying the limitations of the studies, and offer valuable perspectives and insights for potential future research directions. Through a review of 49 articles (22 articles utilizing data while 27 articles did not use data), this study focuses on analyzing the differences in model structure, research data and areas, characterization of prevention and control measures, and main results. Meanwhile, quantitative results such as the reproduction number and critical parameter values are extracted. The study points out that the limitations of existing models are manifested in the lack of heterogeneity in the research and the absence of the results on the scale of herd/flock. The primary reason is the lack of relevant data, indicating the necessity to advance interdisciplinary, multidisciplinary, and transdisciplinary collaboration across multiple departments. Therefore, it is encouraged that the future models should be established from the holistic approach of One Health.</p>\u0000 </div>","PeriodicalId":234,"journal":{"name":"Transboundary and Emerging Diseases","volume":"2025 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/tbed/1393722","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143114002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to assess the frequency of detection at admission and the in-hospital acquisition of CRE from perirectal swabs in dogs and cats hospitalized in an Italian Veterinary Teaching Hospital (VTH). Of the 150 patients sampled, 11.3% (<i>n</i> = 17) were CRE carriers at admission, 25.6% (<i>n</i> = 34) acquired CRE in their commensal microbiota during their hospital stay, and 2% (<i>n</i> = 3) developed an infection caused by CRE. Genotypical analysis showed that in 100% (78/78) of the CRE isolates (44 <i>Escherichia coli</i>, 33 <i>Klebsiella pneumoniae</i>, and 1 <i>Klebsiella aerogenes</i>) carbapenem resistance was conferred by the carbapenemase gene bla_NDM, suggesting an endemic presence of such gene within the hospital. Co-occurrent <i>β</i>-lactamase-encoding genes were found in most of the isolates.

However, the risk to human public health of different recombinant types of H5N6 viruses remains unclear. Recently, two types of different recombinant H5N6 viruses were isolated from chickens. One of the viruses possessed six internal genes originating from H9N2, named A/Chicken/Hubei/112/2020 (H5N6) (abbreviated 112); the other virus possessed PB2, PB1, PA, and NP originating from H5N1, while the M and NS genes were derived from H9N2, named A/Chicken/Hubei/125/2020 (H5N6) (abbreviated 125). Here, we investigated the receptor binding properties, pathogenicity, and transmissibility of the two H5N6 AIVs. The results showed that 112 and 125 could bind <i>α</i>-2,3-linked sialic acid receptor (avian-like receptor) and <i>α</i>-2,6-linked sialic acid receptor (human-like receptor). However, 125 and 112 showed different pathogenicity in mice. Mice infected with 125 lost only a slight body weight and all survived, while mice infected with 112 lost weight rapidly and all died within a week of infection. Furthermore, in the transmission experiment, 125 could only transmit through direct contact, while 112 could transmit not only by direct contact but also by aerosol. The above results indicated that 112 exhibited enhanced pathogenicity and transmissibility compared to 125, suggesting that the H5N6 virus, whose internal genes were derived from H9N2, could pose a greater threat to human health.

This study aimed to differentiate closely related ASFV strains through the analysis of the intergenic region (IGR) between <i>I73R</i> and <i>I329L</i> genes. In 2019, genetic analysis confirmed one IGR I type case and two IGR III type cases in Paju, followed by two more IGR III type cases in 2020. After a period of detecting only the IGR II type, IGR III type cases re-emerged in Pohang and Cheong-song in November and December 2023. Genetic analysis using <i>B646L</i>, <i>CP204</i>, <i>B602L</i>, and <i>EP402R</i> genes confirmed that the IGR III strains belong to genotype II and serogroup 8, similar to the Georgia/2007/1 strain but differing in IGR type. Since the first occurrence of ASF in wild boars in South Korea, we have continuously monitored the introduction and variation of ASFV. As a result, we reconfirmed the presence of the IGR III type ASFV in 2023, 3 years and 8 months later, in a different area from where it was last detected.

Several different modes of ASFV transmission make it difficult to predict and prevent ASFV introduction to the free area and its spread in the affected area. Indirect transmission through contaminated surfaces could be one of the possible routes to introduce ASFV to the United States due to its high resistance on environmental surfaces and the frequency of international movements. However, there is limited knowledge about environmental samples for ASFV surveillance, when compared to clinical samples from infected pigs. Therefore, the aim of this study was to develop methods for better detection of ASFV DNA in the presence of four different types of organic contaminants: soil, swine feces, feed dust, and their mixture. The presence of organic contaminants negatively affected the sensitivity of ASFV DNA detection. Centrifugation and filtration were crucial for ASFV detection in environmental samples with soil and mixture, whereas filtration reduced the sensitivity of ASFV DNA detection in samples from clean surfaces and swine feces- and feed dust-contaminated surfaces. Detection of ASFV was significantly improved when sampled by the sponge stick with DNA/RNA shield when compared to the cost-effective sampling strategy, the cotton gauze with phosphate-buffered saline. These findings highlight the effect of organic contaminants and the use of the nucleic acid stabilization buffer on ASFV diagnostic performance and provide important background for ASFV preparedness.</p>\u0000 </div>","PeriodicalId":234,"journal":{"name":"Transboundary and Emerging Diseases","volume":"2024 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/tbed/8841168","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we developed a propidium monoazide (PMA) qPCR assay for rapid and universal detection of infectious PRRSV in this study. After comparing the inactivation efficacies of distinct disinfectants, ultraviolet (UV) light, and heat, heat at 72°C for 15 min was determined as an effective strategy for PRRSV inactivation, which was confirmed by virus isolation and immunofluorescence assay (IFA) detection. In addition, PMA pretreatment parameters were optimized, including PMA concentration (5 μM), PMA binding time (25 min), PMA binding temperature (37°C), and photolysis time (25 min). The optimal concentration of primers and probes adapted from our previous study was redetermined. The optimized PMA-qPCR assay exhibited satisfied specificity, sensitivity, and reproducibility. Furthermore, the new PMA-qPCR was applied on the detection of 270 clinical samples (including 57 environmental feces, 177 lungs, 33 lymph nodes [LN], and 3 sera) and compared with previously developed qPCR. Eighty samples were qPCR positive, while only 63 samples were PMA-qPCR positive. No virus could be isolated in the 17 qPCR-positive but PMA-qPCR-negative clinical samples; meanwhile, PRRSV could be isolated in representative PMA-qPCR-positive samples, supporting that only live PRRSV isolates in distinct samples could be detected by this PMA-qPCR assay.

In addition, studies on vector interactions often focus on a one-to-one host–vector relationship, even though it is crucial to analyze how multiple vector species interact with multiple hosts. These biases particularly affect our knowledge of sandflies, the main vector of <i>Leishmania</i> spp. and various phleboviruses, that are rarely explored in non-peridomestic habitats and in the context of multiple interactions with various hosts. To reveal the multihost/multivector network involving phlebotomine sandflies in a semiarid and poorly populated area of Spain, we sampled the sandfly community close to avian nests by means of two trapping methods (Centers for Disease Control (CDC) and sticky traps) during 3 years and identified the blood-meal source of all engorged sandflies. We detected six phlebotomine species with <i>Phlebotomus perniciosus</i>, <i>P. papatasi</i>, and <i>Sergentomyia minuta</i> being the most abundant ones.
