The ongoing COVID-19 crisis has emphasized more than ever the relevance of wildlife as a potential source pathogens for other species, including humans, and importance that interactions with can have on global health. Nevertheless, in veterinary world, concept reservoir detrimental to livestock production health been known centuries. Well-known examples diseases which interface plays, or played, an important role include rinderpest, avian influenza, foot mouth disease (FMD), African swine...
Biosecurity is crucial for safeguarding livestock from infectious diseases. Despite the plethora of biosecurity recommendations, published scientific evidence on effectiveness individual measures limited. The objective this study was to assess perception Swiss experts about and importance on-farm cattle swine farms (31 30 measures, respectively). Using a modified Delphi method, 16 disease specialists (8 each species) were interviewed. asked rank that written cards, by allocating score 0...
Antimicrobial use in animals is known to contribute the global burden of antimicrobial resistance. Therefore, it critical monitor sales for livestock and pets. Despite availability veterinary data most European countries, surveillance currently lacks consumption monitoring at animal species level. In this study, alternative methods were investigated stratifying per using Swiss (2006-2013). Three approaches considered: (i) Equal Distribution (ED) allocated evenly across all each product was...
Reducing antimicrobial use (AMU) in livestock is requested by Public Health authorities. Ideally, this should be achieved without jeopardizing production output or animal health and welfare. Thus, efficient measures must identified developed to target drivers of AMU. Veterinarians play a central role the identification implementation such interventions. Sixty-seven veterinarians with expertise Denmark, Portugal Switzerland participated an expert opinion study aimed at investigating...
Rattus spp. may acquire and disseminate antimicrobial resistant bacteria or resistance (AMR) genes. We conducted a scoping review to synthesize available research findings on AMR in describe the size scope of literature epidemiology The was performed according Preferred Reporting Items for Systematic Reviews Meta-Analysis extension Scoping (PRISMA-ScR). search focused scientific peer-reviewed publications focusing peridomestic limited English PubMed, Web Science Scopus between 2000 2021....
Given the close contact between animals, animal products, and consumers in wet markets, fresh meat products are considered a potential source disseminator of antimicrobial-resistant (AMR) bacteria near end food chain. This cross-sectional study was conducted to estimate prevalence select AMR- E. coli chicken collected from markets Hong Kong determine target genes associated with observed resistance phenotypes. Following stratified random sampling design, 180 half-chickens were purchased 29...
Coxiella burnetii infection (Q fever) is a widespread zoonosis with low endemicity in Switzerland, therefore no mandatory public report was required. A cluster of initially ten human cases acute Q fever infections characterized by prolonged fever, asthenia and mild hepatitis occurred 2012 the terraced vineyard Lavaux. Epidemiological investigations based on patients' interviews veterinary included environmental sampling as well Coxiella-specific serological assay molecular examinations...
The recent Q fever epidemic in the Netherlands raised concerns about potential risk of outbreaks other European countries. In Switzerland, prevalence animals and humans has not been studied years. this study, we describe current situation with respect to Coxiella (C.) burnetii infections small ruminants as a basis for future epidemiological investigations public health assessments. Specific objectives cross-sectional study were (i) estimate seroprevalence C. sheep goats, (ii) quantify amount...
Veterinary antimicrobial consumption patterns vary considerably across Europe. These differences are not only limited to the total amount consumed, but also observed with regards relative proportion of various classes used. Currently, most data on veterinary antimicrobials reported at sales level without any information by different animal species. This hinders a proper comparison species between countries. However, it is imperative improve our understanding usage level, as well drivers...
Decades of warnings that the trade and consumption wildlife could result in serious zoonotic pandemics have gone largely unheeded. Now world is ravaged by COVID-19, with tremendous loss life, economic societal disruption, dire predictions more destructive frequent pandemics. There are now calls to tightly regulate even enact complete bans, while others call for nuanced approaches since many rural communities rely on sustenance. Given pressures from political drivers resource limitations...
To describe the effect of HAART on Kaposi sarcoma herpes virus (KSHV) antibody response and viremia among HIV-positive MSM.A follow-up study 272 MSM (including 22 with sarcoma) who first initiated between January 1996 July 2004 in Swiss HIV Cohort Study.For each individual, two serum samples, one at initiation another 24 months later, were tested for latent lytic KSHV antibodies using immunofluorescence assays, PCR. Factors associated changes titers evaluated.At initiation, 69.1 75.0%...
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected millions of people worldwide since its emergence in 2019. Knowing the potential capacity virus to adapt other species, serological surveillance SARS-CoV-2 infection susceptible animals is important. Hong Kong and Seoul are two Asia’s most densely populated urban cities, where companion often live close contact with humans. Sera collected from 1040 cats 855 dogs during early phase pandemic were tested for antibodies...
Extended-spectrum β-lactamase-producing Escherichia (E.) coli (ESBL-EC) in the clinical setting have emerged as a major threat to public and animal health. Wildlife, including Rattus spp. may serve reservoirs spreaders of ESBL-EC environment. Peridomestic rats are well adapted living proximity humans animals variety urban agricultural environments sentinels identify variations within their different habitats. In this study, set 221 (Rattus norvegicus, R. tanezumi, andamanensis, Niviventer...
Human exposure to bacteria resistant antimicrobials and transfer of related genes is a complex issue occurs, among other pathways, via meat consumption. In context limited resources, the prioritization risk management activities essential. Since antimicrobial resistance (AMR) situation differs substantially between countries, should be country specific. The objective this study was develop systematic transparent framework rank combinations species selected classes found in meat, based on...
Chelonians are recognized as a source of human salmonellosis through direct contact or consumption their meat. Freshwater turtles sold for food widely available in wet markets Asia. In this pilot study, 50 belonging to three species were randomly sampled from throughout Hong Kong. The humanely euthanised and feces the colon Salmonella culture. isolates obtained serotyped examined phenotypic antimicrobial resistance presence genes. study reports high prevalence (42%, 95% CI: 29.4-55.8)...
Coxiella burnetii is globally distributed but evidence of zoonotic transmission in the Caribbean region scarce. The bacterium presence suspected on island St. Kitts. risk exposure veterinary students was reported other regions world not documented region. present study aimed to evaluate C. for pre-clinical (mostly coming from U.S.) attending an island-based school. A cross-sectional conducted compare incoming and outgoing students' seroprevalence. Serology performed using indirect...
Abstract Background Pig farming in Hong Kong differs markedly from other places the world, with a highly urbanised population, majority of pigs being imported for slaughter, and limited on-farm veterinary support. Little is known about barriers attitudes pig farmers their expectations new health production management service provided by veterinarians. We collected qualitative quantitative data to 1) describe farms, 2) identify 3) perceptions service. Thematic analysis was conducted...
Salmonella is an important agent of gastrointestinal disease in humans. While livestock, such as cattle, poultry, and pigs, are well-recognised animal reservoirs Salmonella, there a lack data on edible frogs, even though frog meat popular food worldwide. In this study, 103 live Chinese frogs (Hoplobatrachus rugulosus) were collected from wet markets throughout Hong Kong. After euthanasia, faeces or cloacal swabs examined for Salmonella. Overall, spp. isolated 67 (65%, CI: 0.554-0.736) the...
