Researchers have developed a simple model that characterizes the biomechanics of Ebola virus-host cell adhesion, findings that could provide new and helpful information on the road to developing an effective Ebola treatment.
Researchers have developed an innovative method for analysing the genome of the Wolbachia bacterium. This endosymbiotic* bacterium infects more than 70 percent of insects and is capable of influencing insect transmission of pathogens such as dengue or Zika virus.
This US Department of Agriculture (USDA) infographic provides a quick reference for how African swine fever (ASF) is spread.
The study revealed extensive genetic diversity as well as spatial dispersal of EEEV within Florida. Additionally, Das and colleagues observed more clustering of the disease in the Panhandle region. The findings, they said, indicate that EEEV is present year-round in the Florida Panhandle and that the region could be “seeding” EEEV epizootics in the rest of the state and the Northeastern US.
In December 2017, a dog that had pneumonic plague was brought to a veterinary teaching hospital in northern Colorado. Several factors, including signalment, season, imaging, and laboratory findings, contributed to delayed diagnosis and resulted in potential exposure of >116 persons and 46 concurrently hospitalized animals to Yersinia pestis.
Researchers conducted a serosurvey of 155 healthcare workers and 124 household and community members who had close contact with 18 patients who had laboratory-confirmed Nipah virus infections in Kerala, India. They detected three subclinical infections; two persons had IgM and IgG and 1 only IgM against Nipah virus.
New study will identify genes that reduce Influenza A infection in pigs and chickens, and genes that limit the spread of the virus to people.
This review examines evidence from the history of variolation, data on mucosal infection collected in the last decades of smallpox transmission, aerosol measurements, animal models, reports of smallpox lung among healthcare workers, and the epidemiology of smallpox regarding the potential importance of fine particle aerosol mediated transmission.
This study provides the first evidence of Ebola virus-infected survivors from the index site of the west African outbreak. A thorough retrospective epidemiological study done concomitantly among the resident adult population expands understanding of the initiating events including transmission dynamics, probable transmission chains, lower case fatality rates, and the presence of both mild and asymptomatic cases.
More than 200 pigs have been slaughtered after household farms in Hung Yen and Thai Binh provinces were suspected to be contaminated with African swine fever. The strange thing is the affected areas are far from China -- where the disease is ravaging its pork industry -- raising questions of how the disease spread to the remote farms.
