Study reveals how Lyme disease spreads through the body
Lyme disease bacteria
Lyme disease bacteria (Borrelia burgdorferi) spreads through the body by clinging to the lining of blood vessels.

Cell-imaging approach offers new insights

Research by the University of Toronto has revealed how Lyme disease bacteria spreads through the body.

Published in the journal Cell Reports, the study found that a special adhesion protein called BBK32 helps Lyme disease bacteria (Borrelia burgdorferi) cling onto and move along the inside lining of blood vessels.  

"It's likely that this property helps the bacteria get to sites where they might be able to persist longer, and this property might therefore make it harder to treat infections caused by these bacteria," explains first author Rhodaba Ebady.

In the study, the team developed a live-imaging-cell based system that provides both molecular and biomechanical insights into how bacteria travels throughout the body.

Using genetically modified strains of Borrelia burgdorferi, the team watched through a microscope as the bacteria - marked with fluorescent green protein - moved across cells in real time.

Their findings suggest that drugs targeting BBK32 could help to prevent or slow down the spread of Lyme disease bacteria to joints, the heart and nervous system.

This would eliminate or reduce the severity of symptoms like heart inflammation, arthritis, facial paralysis and nerve pain, the researchers say.

Furthermore, because BBK32-like proteins are produced by pathogens like Staphylococcus aureus and Streptococcus pyogenes, the researchers believe their findings may also be relevant to other serious conditions, like pneumonia and inflammation affecting the heart.

Looking ahead, the team hope to identify endothelial receptors that BBK32 interact with, assess the biomechanical role of bacterial flagella in vascular interactions, and try to determine how bacteria target specific endothelia associated with different tissues.

More broadly, the team hope their cell-imaging approach could be used to study how other pathogens spread throughout the body.

FIVP launches CMA remedies survey

News Story 1
 FIVP has shared a survey, inviting those working in independent practice to share their views on the CMA's proposed remedies.

The Impact Assessment will help inform the group's response to the CMA, as it prepares to submit further evidence to the Inquiry Group. FIVP will also be attending a hearing in November.

Data will be anonymised and used solely for FIVP's response to the CMA. The survey will close on Friday, 31 October 2025.

Bluetongue reaches Wales for first time in 2025

The Animal and Plant Health Agency (APHA) has revealed that bluetongue has been confirmed in Wales for the first time in 2025.

In their latest statistics, APHA records a total of 109 cases of BTV-3 or BTV-8 in Great Britain in the 2025-2026 vector season.

The total number of BTV-3 cases in Great Britain this season is 107. This includes 103 cases within the England restricted zone and four cases in Wales.

There has also been two cases of BTV-8, which were both in Cornwall.

As a result of the cases in Wales, a Temporary Control Zone (TCZ) is enforced in Monmouthshire. Animals can move freely under general license within the England Restricted Zone, however animals with suspected bluetongue must stay on their holding.

All premises testing positive for blue tongue can be viewed on this map.
