Strangles, caused by the bacteria
Streptococcus equi, is the most frequently diagnosed infectious disease of horses, with 600 outbreaks estimated to occur in the United Kingdom each year.
Streptococcus equi invades the lymph nodes of head and neck of horses, causing them to swell and form abscesses that can, in around 2% of cases, literally strangle the horse to death. Some of the horses that recover from strangles remain persistently infected. These apparently healthy animals shed bacteria into the environment and spread the disease to other horses that they come into contact with.
Using standard diagnostic testing, the
Streptococcus equi strains look almost identical. But by carefully examining the DNA of the bacteria, the team were able to track different variants as they spread across the world.

The stark inequalities within the South African population were brought to the fore in a new study by Stellenbosch University (SU) researchers that shows that poorer communities were much harder hit by the first wave of the Covid-19 pandemic than more affluent communities.
These findings suggest that lockdown regulations meant to curb the spread of Covid-19 held little benefit for socio-economically vulnerable groups whose living conditions prevent them from adhering to measures such as social distancing and self-isolation. The researchers appeal to decision-makers to consider alternative prevention measures to protect vulnerable communities from Covid-19 infection.

A healthy system of gut bacteria, or microbiota, is crucial to health: Gut bacteria not only aid with digestion, but also play an important role in the body s immune response. Infants, however, are not born with full-fledged gut microbiota, which makes it difficult for them to fight off intestinal infections.
Although little is known about how the immune system develops during infancy, new research from the Virginia-Maryland College of Veterinary Medicine s Department of Biomedical Sciences and Pathobiology sheds significant new light on the subject.

Drones to characterize aquatic habitats of malaria vectors in the Amazon, Malaysian Borneo and Burkina Faso Malaria control programmes rely on interventions targeting mosquito-breeding sites to reduce mosquito populations and malaria transmission. A precise knowledge of ecological characteristics of mosquito aquatic habitats is key for such interventions.
This webinar will have three presentations discussing how drones can help in the characterisation of aquatic habitats of malaria vectors in the Amazon, Malaysian Borneo and Burkina Faso. Presentations will be followed by an interactive discussion with the panellists and audience, addressing the use of drones to understand the ecological features of mosquito breeding sites.
