Spread plate is best as it is quicker and gives consistent results (so long as the inoculum is standardised) and you can immediately see any contamination. 

Could you clarify your mean, please?

Dear Rashid Ramazanzadeh

Which technique gives better results for antimicrobial sensitivity testing?

Pour-plate or Spread plate method?

 Dear Dr. Mac Dz

I think  Spread plate is better.

Dear Rashid Ramazanzadeh

Can you give an explanation to your response?

take a look

Pour plating is usually used when you want to determine CFUs/ml (quantify a bacterial stock for example) or PFUs/ml (quantify a phage stock). Once it's pour plated, you can't really dig the bacteria out of the agar.

Spread plating is used when you want to isolate specific clonal colonies, for example, after cloning to select for cells that uptook a plasmid.

For Antimicrobial testing spread plate method used because we can check particular microorganisms sensitivity towards the antibiotics

Dear Alireza Mordadi 

Thanks but your link says "page not available"

Dear Vijay Vardhan Pandey 

Does pour-plate technique gives false results for antimicrobial sensitivity testing?

Why spread plate is better than pour-plate technique in antimicrobial sensitivity testing?

it is to link

excuse me

Dear Mac Dz,

Antimicrobial sensitivity we use spread plate because we need sensitivity for particular bacteria.. but for pour plate we goes for lawn culture....it is describe as appearance of bacterial colonies when all the individual colonies on a petri-dish agar plate merge to form a field or mat of bacteria. Bacterial lawns find use in screens for antibiotic resistance and bacteriophage titering.

Spread plate is best as it is quicker and gives consistent results (so long as the inoculum is standardised) and you can immediately see any contamination. 

Dear Mac Dz. Spread  plate technique is better for antimicrobial sensitivity test.

Spread plate is better than pour plate (using a standardized inoculum) as it is quick, easier to perform and better to detect contamination

Spread plate technique is better and easier in terms of complexity. Pour plate is more laborious and requires skill. Moreover, contaminants are easily spotted with spread plate.

Dear Aniekan-Augusta O Eyo and Others

Will there be a change in the zone of inhibition if the same bacterial inoculum and the same antibiotic is used in both techniques?

Which technique will give a more precise zone of inhibition?

Since you need to check the activity by measuring inhibition zones I recommend you to use spread plate technique. Otherwise, in terms of observing and measuring inhibition zones, you may face troubles. And also one important point is checking contamination. It will be easier for you to observe and identify, whether there are any contaminations in spread technique.
