SWANS IN THE Greater Dublin and Co Kildare areas have been found to frequently carry antimicrobial resistant (AMR) bacteria in their guts that are very similar to those that cause infections in humans which are difficult to treat.
As part of a new study, researchers from the University of Galway, working with the Irish Midland Ringing Group, collected faecal samples from 17 swans living in several locations around the Greater Dublin Area, including Broadmeadow Estuary in Swords, Bray harbour, Newbridge, Co Kildare, and along the Grand Canal in Dublin city.
An analysis of the 17 samples taken found that 11 were positive for one or more AMR bacteria, with 35 AMR bacteria detected overall. The most common type of AMR bacteria detected were multidrug-resistant E coli.
The study states that it is likely that the high rate of detection of these AMR bacteria in swans is linked to human-associated pollution of their shared water habitat with treated and untreated wastewaters and through storm water overflows, but it did not rule out direct spread from swan to swan.
AMR occurs when bacteria and viruses change over time and no longer respond to medicines, making infections harder to treat and increasing the risk of disease spread and severe illness.
Dr Liam Burke, lecturer in bacteriology in the School of Medicine at University of Galway and the study’s principal investigator, said the university had previously conducted studies looking at the presence of AMR bacteria in water.
Speaking on RTÉ’s Morning Ireland, he said: “We found some of those that are causing infections in humans in canals, in rivers and in coastal areas in a few different places around Ireland, including Dublin, and we always noticed that wherever we found these bacteria, there was always swans present in the canals.
“So we decided that it would be worth looking to see whether swans were picking up bacteria that are resistant to these antibiotics.”
Burke said that if animals are carrying these drug-resistant bacteria, they can pass them on to humans.
“If swans are in parks and other areas where humans might go for recreation, they can spread the bacteria in the water there, and if we are exposed to that water and swallow that water, then there’s potential for us to become colonised with these AMR bacteria.”
He said that if this bacteria gets into our gut or bloodstream, it can cause an infection that is difficult to treat, adding that first-line antibiotics might not be effective and “last resort antibiotics” might be needed to kill these bacteria.
According to Burke, while a lot is known about the spread of the spread of AMR in humans and in livestock, the extent to which wild animals can transmit AMR is a “big knowledge gap”.
“It’s important for us to know what are the potential risks of dissemination in wild animals and in the environment,” he said.
The World Health Organisation states that AMR is one of the top global public health and development threats. A study published in the Lancet estimated that bacterial AMR was directly responsible for 1.27 million global deaths in 2019 and contributed to 4.95 million deaths.
“We really need to try and control the spread of these antimicrobial resistant bacteria,” Burke said.
He said that some of the ways to do this is by limiting their dissemination in the environment, through wastewater treatment discharges, and limiting their environmental pollution.
The University of Galway-led study was funded by the EU’s Erasmus+ Programme, the Environmental Protection Agency (EPA) and the HSE.

At no point in the article is there a mention of life being tough for the residents of the flat complex so I’m not sure what “snuffbox” is going on about!!!
The few pictures shown here are great. I wish her the best of luck with the exhibition.
Snuffbox what a judgemental ignorant comment to make about the photographer. This woman has a great eye for capturing life and sharing it with a wider audience, best of luck in her exhibition.
Snuffbox, what are you on about? The pictures are from loads of different people that live and lived in the flats over the years not just the photographers family. Best of luck to her for organizing this exhibition, maybe it will inspire others to remember where they came from.
So what! Lifes just as tough everywhere else these days.she took a few photos just cause her granny was from there.
Hi Snuffbox, I refer you to Vanessa’s comment below,
Thanks, Susan, Editor.
like one of the unbelievables once said. “no matter where you go on holidays you never have to pack a bollix because your always sure to find one”
Love those pictures. Love when an artist/photographer ties in history and life, interesting to see that although we are sixty years on the kids are still the same. I am sure not much has changed in the flat complex either.
I am from Pearse house and it was great to see a lot off people coming in and meeting people that they have not seen in years and I met people that worked with my dad telling all the old stories what they got up two thanks well done xxx
Was a great experience for my mam and myself was great to c people who knew me as a child and knew her and chat and remember old times
Wish I was able to go and visit the flats as my Dad was born and raised in 5b Pearse house
His name was Godfrey ( Golly ) Coffey. my Granny Brigid lived there until she died age 83. I have many happy memories of visiting Grannys and meeting my uncle Vincent and my cousin Brigid who often stayed at my grannys house. Ive lived in Australia a long time now but go back frequently . My sister Barbara is visiting Dublin in August this year so she will make an effort to visit the recreated flat and record some pics for me .
