NewsNew research suggests few people get sick after bite from ticks infected with Powassan virus
Scientists have published new findings on Powassan virus, reporting that people bitten by black-legged (or deer) ticks that tested positive for the virus did not show signs or symptoms of disease.

NewsNew agent effective against drug-resistant malaria parasites
Scientists have developed a promising new antimalarial agent, DIF-1(+3), which is a derivative of Dictyostelium differentiation-inducing factor-1 (DIF-1).

NewsNew study confirms mammal-to-mammal avian flu spread
A new study provides evidence that a spillover of avian influenza from birds to dairy cattle across several U.S. states has now led to mammal-to-mammal transmission – between cows and from cows to cats and a raccoon.

NewsScientists pinpoint how a red seaweed reduces methane emissions from cows
New research into the microbiome of cattle rumen has implications for addressing a leading contributor to climate warming.

NewsFirst locally transmitted dengue cases reported in Iran
On June 14 the Ministry of Health and Medical Education (MoHME) of Iran reported the first two locally acquired cases of dengue recorded in the country. As of 17 July, the total number of locally acquired dengue cases in the country has risen to 12.

NewsResearchers expose the rules behind dengue’s invasion strategies
Scientists uncover fundamental rules for how dengue virus infects its mosquito and human hosts, providing hope for identifying therapeutic approaches.

NewsUrgent action needed to combat rising antimalarial resistance in Africa
Urgent action is needed to prevent a surge in malaria-related sickness and death in eastern Africa, scientists say.

NewsBartonella and babesia co-infection detected in patients with chronic illness
A small pilot study has found evidence of human co-infections from Bartonella and Babesia odocoilei, a protozoal tick-borne infection primarily found in deer, moose and other cervids.

NewsIntensive farming could raise risk of new pandemics
Intensive livestock farming could raise the risk of new pandemics, researchers have warned. A study examines the effect of social and economic factors – which are often overlooked in traditional assessments.
-
NewsStudy unveils complexity of zoonotic transmission chains
Researchers have dissected the complex interactions involved in zoonoses, introducing the concept of a “zoonotic web,” a detailed network representation of the relationships between zoonotic agents, their hosts, vectors, food sources, and the environment.

NewsReceptors make dairy cows a prime target for influenza
Researchers who examined mammary gland samples from two cows infected with highly pathogenic avian influenza found a rich supply of sialic acid, which could shed light on how the virus attaches to hosts and help develop measures to slow the spread.

NewsHibernation status matters when white-nose syndrome pathogen infects bats
The fungal pathogen that causes white-nose syndrome (WNS) in bats uses different cell entry strategies depending on the host’s hibernation status – cold and inactive, or warm and active.
-
NewsMayaro and chikungunya viruses observed circulating at the same time in the Brazilian Amazon
Infection by one virus was expected to afford protection against the other, preventing co-circulation. Researchers are warning of the risk of transmission of Mayaro in urban areas due to deforestation and advocate more effective epidemiological surveillance.

NewsRaw milk is risky, but airborne transmission of H5N1 from cow’s milk is inefficient in mammals
New research suggests that exposure to raw milk infected with the currently circulating virus poses a real risk of infecting humans, but that the virus may not spread very far or quickly to others.

NewsCurrent strategies ineffective in controlling Salmonella Dublin in Danish cattle
Researchers have shown that, despite stringent movement restrictions among Danish cattle farms, Salmonella Dublin continues to propagate, indicating that current strategies are insufficient to curb the spread of the disease.

NewsDengue linked to heightened short- and long-term risk of depression in Taiwan
Analysis of the medical records of nearly 50,000 people who experienced dengue fever in Taiwan suggests that this disease is associated with elevated short- and long-term risk of depression.

NewsScientists explore bird breeding behaviour and microbiomes in the radioactive Chornobyl Exclusion Zone
New research finds surprising differences in the diets and gut microbiomes of songbirds living in the radiation contaminated areas of the Chornobyl Exclusion Zone, Ukraine.

NewsInfected kissing bugs spark wake-up call in Delaware
Researchers are investigating discovery of the insect in Delaware. While common in the Mid-Atlantic, they are vectors of a parasite, Trypanosoma cruzi, that can lead to serious heart problems.

NewsBiting flies on dairy farms can spread bovine mastitis
A study has identified Stomoxys flies (also known as stable flies) as carriers of pathogenic bacteria that cause bovine mastitis.

NewsOlympics: how many days does it take for mosquitoes in Greater Paris to transmit arboviruses?
In the run-up to the Olympic Games, scientists have demonstrated that the tiger mosquito, now present in Greater Paris, is capable of transmitting five viruses - West Nile, chikungunya, Usutu, Zika and dengue - within different time frames.
