We reported two cases with community-acquired pneumonia caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) who returned from Wuhan, China in January, 2020. The reported cases highlight non-specific clinical presentations of 2019 novel coronavirus disease (COVID-19) as well as the importance of rapid laboratory-based diagnosis. 相似文献

ObjectiveTo document the recent livestock related practices and possible unhygienic ways of pathogen entry. Identification of the potential risk factors for the spread of infection is important to design an evidence-based disease control programme.MethodsRapid assessment method was adopted and a purposive sample of 60 dairy farmers were interviewed. The following factors were noted for contributing in primary and secondary transmission of zoonotic infections: (i) persons who come in close contact with animals and their secretions, (ii) management strategies of farm animals (sheds and environment), (iii) management practices adopted at farms, (iv) small scale farmers and rural livestock production systems, (v) milk collection systems.ResultsThis research unveiled the certain routes of zoonotic disease transmission. Certain management practices, precautionary measures and strategies were the pivotal risk factors.ConclusionsThe study emphasizes the need to educate the poor livestock keepers. 相似文献

Brucellae are tiny, aerobic, slow growing, catalase and oxidase positive Gram negative coccobacilli or small rods, which may reach man through exposure to tissues of mammalian hosts via cuts or aerosols, or as food infections mostly through dairy products. As parasites brucellae are extraordinarily successful, causing very long-lasting infections in all mammalian social animals, such as ungulates, canids, and rodents; recently they have been found to also cause disease in pinnipeds and cetaceans. Brucellae as members of the alpha Proteobacteria, have suffered major losses of genomic material as they adapted to their facultative intracellular parasite role, and are able to initiate infection with minimal disturbance of the innate immune system, thus reaching a privileged intracellular niche where they multiply. Brucellae are likely to be among the toughest organisms to control through public health and agricultural policies, even involving detection-slaughter strategies. 相似文献

Australian beef industry worker’s knowledge,attitudes and practices regarding Q fever: A pilot study
《Vaccine》2019,37(43):6336-6341
BackgroundQ fever is a vaccine-preventable zoonotic infection with potentially severe health outcomes and high economic costs that affects agricultural workers, including beef and cattle industry workers, however this population historically have sub-optimal vaccine uptake.ObjectiveTo gather quantitative and qualitative pilot data from Australian beef industry workers on their knowledge, attitudes and practices around Q fever and Q fever vaccination.MethodsA mixed methods approach was used to ascertain the Q fever disease risk perception and vaccination behavior of a purposive convenience sample of beef industry workers attending an industry expo in Rockhampton, Queensland, Australia between May 7th and 9th, 2018.ResultsThe quantitative survey response rate was 83% (n = 86). More than 70% of respondents reported exposure to known Q fever risk factors. Eighty six percent were aware of Q fever, the self-reported uptake of Q fever vaccine was 27% and 9% reported undertaking testing which showed evidence of previous infection. Five main themes emerged from the qualitative data: “Finding the time” among other life priorities to attend a doctor for a vaccine; “Employer responsibility” to provide the vaccine; “My doctor knows me” and could suggest Q fever vaccination; “Assigning Risk” across a range of attitudes, including thinking it would not happen to them, ‘fatalism’, and knowing the danger but taking the risk anyway; and “The Need for Outreach” vaccine delivery services in their communities.SignificanceThese data suggest that a coordinated public health approach to testing and vaccine provision, coupled with an awareness campaign among regional doctors to prompt them to routinely ask patients about their Q fever risk and vaccination history, should form part of a broad approach to Q fever control and prevention. 相似文献

Human sparganosis is caused by cestode larvae (spargana) of the genus Spirometra, which exploit copepods as the first intermediate host. A wide range of amphibians, reptiles, birds, and mammals serve as second intermediate/paratenic hosts. Human infections occur mainly by ingesting raw intermediate/paratenic hosts. Cases are found mainly in China, Japan and Korea, and sporadically also in Thailand and other Asian countries. In the period 1943–2010, there were 52 reported cases of sparganosis in Thailand. The average patient age was 32 years (range 11–82 years). From the available patient information, the prevalence of sparganosis infection was higher among females than males, at a ratio of F:M = 2:1 (27:15). Patients have mainly been found in the northeast, north, and central regions of Thailand, with only a few in the south. Although a single subcutaneous nodular lesion was the most common feature, about one third of patients had ocular lesions. In particular, patients having ocular lesions were about half of total cases reported pre-1990, with several confirmed cases’ applying fresh frog muscle as a poultice to relieve sore eyes, according to traditional medicine. In Thailand, sparganosis is not merely a food-borne disease but is also caused by the traditional belief of applying frog muscles (contaminated with sparganum) to sore eyes. 相似文献

BackgroundFor over four decades, Clostridium difficile has been a significant enteric pathogen of humans. It is associated with the use of antimicrobials that generally disrupt the microbiota of the gastrointestinal tract. Previously, it was thought that C. difficile was primarily a hospital-acquired infection; however, with the emergence of community-associated cases, and whole-genome sequencing suggesting the majority of the hospital C. difficile infection (CDI) cases are genetically distinct from one another, there is compelling evidence that sources/reservoirs of C. difficile outside hospitals play a significant role in the transmission of CDI.ObjectivesTo review the ‘One Health’ aspects of CDI, focusing on how community sources/reservoirs might be acting as a conduit in the transfer of C. difficile between animals and humans. The importance of a One Health approach in managing CDI is discussed.SourcesA literature search was performed on PubMed and Web of Science for relevant papers published from 1 January 2000 to 10 July 2019.ContentWe present evidence that demonstrates transmission of C. difficile in hospitals from asymptomatic carriers to symptomatic CDI patients. The source of colonization is most probably community reservoirs, such as foods and the environment, where toxigenic C. difficile strains have frequently been isolated. With high-resolution genomic sequencing, the transmission of C. difficile between animals and humans can be demonstrated, despite a clear epidemiological link often being absent. The ways in which C. difficile from animals and humans can disseminate through foods and the environment are discussed, and an interconnected transmission pathway for C. difficile involving food animals, humans and the environment is presented.ImplicationsClostridium difficile is a well-established pathogen of both humans and animals that contaminates foods and the environment. To manage CDI, a One Health approach with the collaboration of clinicians, veterinarians, environmentalists and policy-makers is paramount. 相似文献
