Trinity scientists discover how to attack a bacteria that causes cystic fibrosis infections

The common bacteria produces a slimy bio-film that on the lungs that is almost impossible for patients to clear

TRINITY COLLEGE SCIENTISTS have discovered a way to attack a common bacteria that can ultimately cause death to those who suffer from cystic fibrosis.

Pseudomonas aeruginosa is a resilient and adaptable species of bacteria that causes disease by infecting damaged tissue and overpowering people whose immune response is compromised in some way.

It is particularly associated with cystic fibrosis. It thrives on moist surfaces and is often implicated in cross-infection cases in hospitals.

Speaking to Professor of Membrane Structural and Functional Biology at Trinity, Martin Caffrey who headed up the research, he said the bacteria is known as an “opportunistic pathogen” which is the common cause of lung infections in cystic fibrosis patients.

Sticky, slimy glue

“The bacteria produces a moist, viscous, slimy ‘bio-film’ that is hard to attack. It is almost like a glue that lines the lungs and is almost impossible for patients to clear,” he said.

“This sticky, slimy stuff becomes very impenetrable and is not very porous. Detergents and antibiotics can’t get through the bio-film, making it a very difficult thing for medical staff to treat,” he added.

The bacteria also builds up on implants such as hip implants, causing a slimy bio-film on the implant that can cause infection to spread, said Caffrey.

However, he explained that alginate, a major component of this bio-film, is made in the bacterial cells and is passed out via a pore in the outer membrane. This outer membrane helps to ‘ring-fence’ each bacterium from its external environment, while the pores in it provide controlled ‘gateways’ through which the alginate can exit.

Penetrating the bacteria 

Professor Caffrey explained: “If we can knock out the functioning of this pore, we might be able to stop alginate being added to the troublesome bio-film.”

The research looked at the hole that is punched through the membrane – which is just a few atoms wide – which could let antibiotics penetrate the bacteria. “Ultimately if we can block the movement and slow down the growth of bacteria it would be a welcome development,” he said.

He explained that often the bacteria is targeted by a hard-hitting antibiotics but this can build up a huge resistance.

“The idea is to be able to weaken the bacteria so that the body can at least deal with it and have a better chance of fighting it,” explained Caffrey.

    Irish Language Act promised since 2006 by the British Government. The DUP won’t budge on it, and the UK government need to act unilaterally. DUP – British when it suits them, “Ulstermen” when it doesn’t.

    How can Wales and Scotland get language legislation, but the north can’t? If the DUP want to represent “British values”, then they should take heed from Britain where language legislation for indigenous languages like Welsh and Gaidhlig exists.

    @Nigel o’Neill: That’s cool, but this isn’t about “people” you “know”. It’s about a promise by the British government to create an Irish language act as part of a power-sharing agreement and failing to deliver on it.

    It’s about equality for Irish language speakers and not treating them as second class citizens when compared to Scottish Gaelic or Welsh speakers.

    It’s about protecting the indigenous language of this island, irrespective of whether you personally care about it. There is a vibrant Irish language community in the north, 35 gaelscoileanna in the north, and multiple Irish language community centres.

    What’s the point of Britain making agreements if they won’t uphold the promises made in order for them to be agreed?

    @Justin Gillespie: I really don’t know where you’re going with that. The overwhelming majority won’t be acceding to anything like you’re implying. After all, Northern Ireland joining Ireland will require a majority in Ireland in favour. That won’t happen if there’s any commonwealth nonsense or any kind of dual flag. It will be a United, sovereign Ireland – nothing else will pass. Sovereign nation (86% of island) > former statelet of U.K. , non – sovereign (14% of island). Never going to be a marriage of equals.

    Just what do you think we’ll also have to give up?

    Time for an election. If it is brought on by the premature ending of the Executive it will be a plague on sf and DUP. On sf for not nominating over an act that would be put in place when pandemic is over and on the DUP for allowing them have a contrived excuse to pull the plug. Would be great to see the more moderates do well in the next elections in Northern Ireland such as Alliance and SDLP.

    Ah, but this allows a “finely balanced” dig at both, since the DUP didn’t support the GFA that gave rise to devolution in the first place, and Sinn Féin haven taken their seats at Westminster that’d allow them to help pass this language legislation over there.

    That’s false. Language is a devolved matter, there wouldn’t be a vote on it in Westminster. And since the DUP will never implement it in a devolved manner, it’s up to the UK government to act and implement one.
