A Johns Hopkins University scientist is studying the ways Nipah virus affects carrier fruit bats to better understand how it spreads to humans.
Researchers discovered that the presence of the Leishmania RNA virus in disease-carrying parasites leads to more aggressive forms of leishmaniasis.
Despite significant gains in understanding of Shigella infection, it remains unknown how the bacteria initiate contact with the colonic epithelium. This research identified conditions that mimic some features of gastrointestinal transit and that enable Shigella to express adherence structural genes.
Researchers conducted a review of molecular and serological investigations through PubMed and EMBASE from September 2012 to 15 November 2018 to measure sub-clinical or asymptomatic Middle East Respiratory syndrome coronavirus (MERS-CoV) infection within and outside of health care settings.
Researchers reviewed human plague cases in Zimbabwe and risk factors associated with the epidemiology and ecology of the disease.
Eight viruses isolated from farmed poultry in South China during 2017–2018 were selected as representative strains for further systematic study. Findings suggested that the H9N2 AIVs circulating in poultry recently acquired an enhanced ability to transmit from avian to mammalians, including humans.
An African swine fever case at a pig farm on Seokmo Island fuels speculation that wildlife could be responsible for the spread of the virus in South Korea. Only one bridge connects the island with other regions, and the farm had only two pigs with no visits from outside cars.
A new study describes the application of effective mosquito surveillance using low-cost traps and a tool that tests each mosquito’s species, feeding material, and the presence of malaria parasites. The study also provides new information that may improve understanding of how malaria is transmitted and consequently could be controlled, including that the female Anopheles mosquitoes (the ones that transmit malaria) diets are more varied than previously assumed.
Candida auris has been found on hospital mattresses, furniture, sinks, and medical equipment. In a new study, researchers wanted to determine how the fungus gets onto those surfaces.
Researchers used machine learning to identify bat species with that could host Nipah virus in India and identified four new bat species as surveillance priorities.
