Abstract
ZusammenfassungDie Familie Poxviridae umfasst derzeit 22 Gattungen, die Wirbeltiere infizieren können. Humanpathogene Pockenviren gehören den Gattungen Ortho‐, Para‐, Mollusci‐ und Yatapoxvirus an. Bis zur Eradikation der Variola vera im Jahr 1979 waren die Pocken, im Volksmund auch Blattern genannt, eine schwerwiegende Gesundheitsbedrohung für die Bevölkerung. Noch heute sind Dermatologen mit zahlreichen Pockenvirusinfektionen konfrontiert, wie den Bauernhofpocken, die als Zoonosen nach Tierkontakten in ländlichen Gebieten oder nach Massenversammlungen auftreten können. In den Tropen können Erkrankungen durch Tanapox‐ oder Vaccinia‐Viren zu den Differenzialdiagnosen gehören. Dellwarzen sind weltweit verbreitet und werden in bestimmten Fällen als sexuell übertragbare Pockenvirusinfektion angesehen. In jüngster Zeit hatten sich Mpox (Affenpocken) zu einer gesundheitlichen Notlage von internationaler Tragweite entwickelt, die eine rasche Identifizierung und angemessene Behandlung durch Dermatologen und Infektiologen erfordert. Fortschritte und neue Erkenntnisse über Epidemiologie, Diagnose, klinische Manifestationen und Komplikationen sowie Behandlung und Prävention von Pockenvirusinfektionen erfordern ein hohes Maß an Fachwissen und interdisziplinärer Zusammenarbeit in den Bereichen Virologie, Infektiologie und Dermatologie. Dieser CME‐Artikel bietet einen aktualisierten systematischen Überblick, um praktizierende Dermatologen bei der Identifizierung, Differenzialdiagnose und Behandlung klinisch relevanter Pockenvirusinfektionen zu unterstützen.

Abstract
The family Poxviridae currently comprises 22 genera that infect vertebrates. Of these, members of the Ortho-, Para-, Mollusci- and Yatapoxvirus genera have been associated with human diseases of high clinical relevance in dermatology. Historically, smallpox had been a notorious health threat until it was declared eradicated by the World Health Organization in 1979. Today, dermatologists are confronted with a variety of poxviral infections, such as farmyard pox, which occurs as a zoonotic infection after contact with animals. In the tropics, tanapox or vaccinia may be in the differential diagnosis as neglected tropical dermatoses. Molluscum contagiosum virus infection accounts for significant disease burden worldwide and is classified as a sexually transmitted infection in certain scenarios. Recently, mpox (monkeypox) has emerged as a public health emergency of international concern, requiring rapid recognition and appropriate management by dermatologists and infectious disease specialists. Advances and new insights into the epidemiology, diagnosis, clinical manifestations and complications, treatment, and prevention of poxviral infections require a high level of expertise and interdisciplinary skills from healthcare professionals linking virology, infectious diseases, and dermatology. This CME article provides a systematic overview and update to assist the practicing dermatologist in the identification, differential diagnosis, and management of poxviral infections.

[PMID: 38026661 PMCID: PMC10665734 DOI: 10.3389/fvets.2023.1277512] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Accepted: 10/24/2023] [Indexed: 12/01/2023] Open
Abstract
Dromedary camels are the preferable livestock species in the arid and semi-arid regions of the world. Most of the world's camel populations are managed under a subsistence/extensive system maintained by migratory pastoralists but intensification is getting more frequent. Even though recently the welfare of camels has been receiving more attention, in many countries there are no regulations to protect their health and welfare. The objectives of this article were to explore the main research topics related to camel welfare, their distribution over time and to highlight research gaps. A literature search was performed to identify records published in English from January 1980 to March 2023 on Dromedary camel welfare via Scopus®, using "Camel welfare," "Camel behaviour," "She-camel" and "Camel management" as search words. A total of 234 records were retained for analysis after automatic and manual screening procedures. Descriptive statistics, text mining (TM) and topic analysis (TA) were performed. The result shows that even though there were fluctuations between years, records on camel welfare have increased exponentially over time. Asia was the region where most of the corresponding authors were located. The first five most frequent words were, "milk," "calv," "behaviour," "femal," and "breed," the least frequent word was "stabl." TA resulted in the five most relevant topics dealing with "Calf management and milk production," "Camel health and management system," "Female and male reproduction," "Camel behaviour and feeding," and "Camel welfare." The topics that contained the oldest records were "female and male reproduction" and "camel health and management system" (in 1980 and 1983, respectively), while the topic named "camel behaviour and feeding" had the first article published in 2000. Overall, even though topics related to camel behaviour and welfare are receiving more attention from academia, research is still needed to fully understand how to safeguard welfare in Dromedary camels.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2023; 147:104754. [PMID: 37295628 DOI: 10.1016/j.dci.2023.104754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 06/05/2023] [Accepted: 06/06/2023] [Indexed: 06/12/2023]
Abstract
Viral infections activate pattern recognition receptors in the host, triggering an innate immune response that involves the production of interferons, which, in turn, stimulates the expression of antiviral effector genes. Viperin is one of the most highly induced interferon-stimulated genes and displays broad antiviral activity, especially against tick-borne viruses. Of late, camelid-borne zoonotic viruses have been on the rise in the Arabian Peninsula, but research into camelid antiviral effector genes has been limited. This is the first report of an interferon-responsive gene from the mammalian suborder Tylopoda to which modern camels belong. From camel kidney cells treated with dsRNA mimetic, we cloned viperin cDNA encoding 361 amino acid protein. Sequence analysis of camel viperin reveals high levels of amino acid conservation, particularly within the RSAD domain. Compared to kidney, the relative mRNA expression of viperin was higher in blood, lung, spleen, lymph nodes, and intestines. The in-vitro expression of viperin was induced by poly(I:C) and interferon treatment in camel kidney cell lines. Viperin expression was subdued in camel kidney cells infected with the camelpox virus during the early stages of infection, suggesting possible suppression by the virus. Overexpression of camel viperin through transient transfection significantly enhanced the resistance of cultured camel kidney cell lines to infection with camelpox virus. Research into the role of viperin in host immunity against emerging viral pathogens of camels will provide insight into novel mechanisms of antiviral activity of the protein, viral immune evasion strategies, and enable the development of better antivirals.

Characterization of the camel pox virus strain used in producing camel pox virus vaccine. Open Vet J 2023; 13:558-568. [PMID: 37304612 PMCID: PMC10257459 DOI: 10.5455/ovj.2023.v13.i5.8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Accepted: 04/10/2023] [Indexed: 06/13/2023] Open
Abstract
Background The camel pox virus (CMLV) is a widespread infectious viral disease of camels. It is necessary to conduct research on new strains for the development of vaccines. Aim The research aims to characterize a novel strain isolated from the CMLV used to produce a CMLV vaccine. Methods The objects of the study were the "M-0001" strain isolated from a sample of animals infected with the CMLV during the epidemic. The cultural and reproductive properties of the virus isolate were studied using primary cell lines from primary trypsinized lamb kidney and testicular cell cultures (LK and LT). Other samples included kidney cell lines from transplanted sheep as well as a kidney cell line from transplanted cattle, Vero (transplanted green monkey kidney cell line), and calf trachea. The strain was polymerase chain reaction (PCR)-tested and sequenced for characterization purposes. Results The PCR results show that the study sample is species specific and corresponds to the CMLV by the size of the cumulative amplifications, which is 241 bp. Given the maximum percentage of a sequence match analyzed by the BLAST algorithm based on the international database and the results of phylogenetic analysis, the M0001 sample was determined to belong to the CMLV (gene bank inventory number KP768318.1). Conclusion The sample "M0001" is located on the same branch with a representative from CMLV. Among the cell cultures tested, the LK and LT cell lines were the most sensitive to the isolated CMLV isolate. Reproducing the virus in these cell cultures remains stable even after 15 consecutive passes. The cytopathic effect of the virus was less pronounced and low in transplanted cell lines, and the cytopathic effect was no longer apparent in the third passage. A genome alignment of the virus has identified potentially conserved sites, and analysis of loci in different virus types revealed one maximally conserved locus. An epizootic strain of the camelina virus "M-0001" candidate to produce vaccines for the camels was obtained. An experimental vaccine sample based on an isolated and charred camellia virus will be created in the future.

Vet Sci 2023; 10:vetsci10050323. [PMID: 37235406 DOI: 10.3390/vetsci10050323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 04/19/2023] [Accepted: 04/26/2023] [Indexed: 05/28/2023] Open
Abstract
Hepatitis E virus (HEV) represents a major cause of acute hepatitis and is considered an emerging public health problem around the world. In the Middle East's and Africa's arid regions, where camels frequently interact with human populations and camel-derived food products are a component of the food chain, camel-borne zoonotic HEV infection is a potential threat. To date, no review paper has been published on HEV in camels. As such, the purpose of the current work is to provide a scientific review of the identification of HEV genotypes seven and eight in camels worldwide to have a better understanding of the current status of this topic and to identify gaps in the current knowledge. Searches were carried out in the electronic databases PubMed, Mendeley, Web of Science, and Scopus, including studies published until 31 December 2022 (n = 435). Once the databases were checked for duplicate papers (n = 307), the exclusion criteria were applied to remove any research that was not relevant (n = 118). As a result, only 10 papers were found to be eligible for the study. Additionally, in eight of the ten studies, the rates of HEV infection were found to be between 0.6% and 2.2% in both stool and serum samples. Furthermore, four studies detected HEV genotype seven in dromedary camels, and two studies have shown HEV genotype eight in Bactrian camels. Interestingly, these genotypes were recently reported in camels from the Middle East and China, where one human infection with HEV genotype seven has been associated with the consumption of contaminated camel meat and milk. In conclusion, more research will be needed to determine the prevalence of HEV infection in camels around the world as well as the risk of foodborne transmission of contaminated camel products. As camels are utility animals in several countries, HEV in these animals may pose a potential risk to public health.

Appl Microbiol Biotechnol 2023; 107:3329-3339. [PMID: 37060465 PMCID: PMC10104765 DOI: 10.1007/s00253-023-12513-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 03/28/2023] [Accepted: 03/31/2023] [Indexed: 04/16/2023]
Abstract
Pandemics like SARS-Cov-2 very frequently have their origin in different animals and in particular herds of camels could be a source of zoonotic diseases. This study took advantage on a highly sensitive and adaptable method for the fast and reliable detection of viral antibodies in camels using low-cost equipment. Magnetic nanoparticles (MNP) have high variability in their functionalization with different peptides and proteins. We confirm that 3-aminopropyl triethoxysilane (APTES)-coated MNP could be functionalized with viral proteins. The protein loading could be confirmed by simple loading controls using FACS-analysis (p < 0.05). Complementary combination of antigen and antibody yields in a significant signal increase could be proven by both FACS and COMPASS. However, COMPASS needs only a few seconds for the measurement. In COMPASS, the phase φn on selected critical point of the fifth higher harmonic (n = 5th). Here, positive sera display highly significant signal increase over the control or negative sera. Furthermore, a clear distinction could be made in antibody detection as an immune response to closely related viruses (SARS-CoV2 and MERS). Using modified MNPs along with COMPASS offers a fast and reliable method that is less cost intensive than current technologies and offers the possibility to be quickly adapted in case of new occurring viral infections. KEY POINTS: • COMPASS (critical offset magnetic particle spectroscopy) allows the fast detection of antibodies. • Magnetic nanoparticles can be adapted by exchange of the linked bait molecule. • Antibodies could be detected in camel sera without washing steps within seconds.
