Which of the following statements regarding infections involving biofilms is false?
-the majority of hospital-acquired infections (nosocomial infections) are related to biofilms.
-there is no way to prevent biofilms from developing on surfaces.
-microbes in biofilms are more resistant to antimicrobials than are independent organisms.
-it is estimated that nearly 70% of all infections are caused by biofilms.

Microbes in biofilms are more resistant to antimicrobials then are independent organisms.

Explanation:

Biofilms are a group of microorganisms that adheres to surface mostly due to individual free flowing bacteria which other organisms join and grows together with. They release slimy glue-like extracellular polymeric substance that provides them the ability to attach to cell surfaces, resist drugs, disinfectants and sterilization. Microbes in biofilm are at an advantage compared to individual microbes because they share nutrients and are protected from conditions that are harmful to them.

clinically, some people often have repeated allergies, eczema and respiratory infections or other parts of the infection, in this case, in addition to some routine tests such as tests for white blood cells, immunoglobulin series, lymphocyte subsets, etc., the five immune immunoglobulin tests are also necessary.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
