Loosely attached cells are readily removed but firmly attached cells are more difficult to remove and may eventually, under the right conditions, grow to form biofilms, usually comprising a microflora of mixed populations closely associated with organic matter, assisting in the persistence of pathogenic bacteria.
Their funding situations mean they live a risky hand-to-mouth existence, and as many grants come with conditions attached, it can be difficult to set aside money for reserves.
