The guidelines below are designed to clarify various responsibilities of community members (users) here at Please read and become familiar with them.


Forum-wide Rules and Regulations


  1. Registration is required in order to post on the forum.
  2. Posts are to be made in a relevant forum. Users are asked to read the forum descriptions before posting. Users consistently posting to the wrong forum may be given a warning.
  3. Users should post in a way that is respectful of other users. Flaming or abusing users in any way will not be tolerated and will lead to revocation of access.
  4. Users are asked to not act as "back seat moderators". If members note an issue which contravenes something in these guidelines they are welcome to bring it to the attention of a Moderator. Only do this if a moderator has not replied to the post within 6 hours. Users who consistently "act" as moderators may be warned or access revoked.
  5. Users should remember this board is aimed at a general audience. Posting generally offensive text, images, links, etc will not be tolerated and will lead to a revocation of access.
  6. Users are asked to respect the copyright of other users, sites, media, etc. Users linking to or asking for information on such material without permission will receive a warning and their post will be removed. If the behavior continues, the users’ access will be revoked.
  7. Users should respect the bandwidth of other users and sites. The use of inline image tags pointing to data stored on third party systems for which the user has not received permission to link to may be removed.
  8. Users should post in a way which is consistent with "normal writing". That is users should not post excessive numbers of emoticons, large, small or colored text, etc. Similarly users should not SHOUT or use excessive punctuation (e.g. ! and ?) in topic titles or posts. Users consistently abusing this will be warned.
  9. Users should use an appropriate, specific, descriptive title when posting a new topic. Examples of good titles include; "How do I start a batch culture", "I’m having problems with my gram stains", etc. Examples of bad titles include; "Help me!", "My bug!", "I've got a question!", etc.
  10. Spam is not tolerated here under any circumstance. This includes offering company services, equipment and supplies, soliciting employment, chain letters, etc. Users posting spam will be warned and their post removed. If the behavior continues, the users’ access will be revoked.
  11. The moderating, support and other teams reserve the right to edit or remove any post at any time. The determination of what is construed as indecent, vulgar, spam, etc. as noted in these points is up to Team Members and not users.


Warnings and Bans (Revocation of Access)


  1. Users will be warned at least once for a particular offence before being banned.
  2. The moderating, support and other teams reserve the right to ban an offending user at any time.
  3. Users who feel they have been unfairly warned or banned are welcome to contact the Moderator team leader. If the Moderator team leader feel you were treated badly they will remove a warning or ban. If you feel the Moderator team leader is also unfair you may contact a Moderator group member. However, a decision at this level is final. Contacting Moderator group members over warning matters should be done so as a very last resort ... group members do not want to be bothered unless vital.
  4. Any attempt to circumvent a temporary ban will lead to that ban being made permanent. Circumvention includes re-registering under a non-banned username, changing IP addresses to evade an IP ban, registering a new email account to evade an email ban, etc.
  5. Permanent bans are a last resort and thought is given before implementing them.

PhD Comparative risk of antimicrobial resistance transfer - Teagasc

PhD Comparative risk of antimicrobial resistance transfer from poultry, pig and bovine manure to grassland
Oak Park, Carlow,
Seeking a highly motivated and able candidate to undertake a PhD project in microbiology that will address questions around the transfer of antimicrobial resistance (AMR) in the environment. AMR is amongst the foremost challenges to public health globally, threatening the effective prevention and treatment of animal and human infections, and requiring action across a wide range of sectors of society. There is increased concern within the food and agriculture industries due to detection of increased levels of AMR in human pathogens and increased awareness of the problems by consumers. Globally we still do not understand the transmission and selection of AMR along the food chain. With increased productivity in the dairy and meat production industries comes increased quantities of organic waste. As part of the circular economy this is frequently reused as fertilizer on grassland. Animal manure has been identified as a hotspot of mobile AMR as concentration of antibiotics and AMR genes and bacteria are excreted from food animals. This project proposes to compare the relative risks of three manure types (poultry, pig and bovine) in the dissemination and proliferation of AMR transfer and maintenance at the start of the food chain. It’s objectives are to close the knowledge gaps that exist at the interfaces between environmental factors (soil) and agricultural practices (manure application) and the food animals (from manure via grass). It will also identify the manure and farming practices that minimize the risk of AMR transfer to soil and grass. The main aims are to (1) Characterise the AMR genes and bacteria in Irish pig, poultry and bovine manure; (2) Identify the resistant bacteria and AMR genes capable of surviving in the soil and on the grass during the growth period after manure application; (3) Elucidate if the quantity and types of AMR genes and bacteria vary or reduce over time and (4) Compare the correlation between microbiome changes and AMR diversity and abundance over time in grassland.
This project will provide valuable multidisciplinary training and research opportunities in microbiology, molecular biology, microbiome analysis, environmental science and bioinformatics. The student will join a successful research group, and lively graduate training communities, and will also receive training in other aspects of scientific work, e.g. result dissemination, writing for publication and conference presentations.
Applications are invited from graduates holding at least a 2.1 class honours degree or M.Sc. in Biology, Microbiology, Environmental Science or a related discipline. Prior experience in microbiology would be advantageous. Fluency in English are essential.
The PhD Fellowship is a joint research project between Teagasc and NUI Maynooth. Supervision will be provided by Dr Fiona Walsh (Maynooth), Dr Kaye Burgess (Teagasc) and Dr Fiona Brennan (Teagasc). The fellowship funding is €22,000 per annum and includes University fees of up to a maximum of €6,000 per annum and is tenable for 4 years.
