To me it has always meant susceptible to increased doses of the antibiotic. 

Dear Ali Asger Bhojiya,

Intermediate in antibiotic resistance pattern come under resistant range or pattern. 

Only you can show your results for sensitive which came under sensitive range or pattern. and rest of Intermediate and Resistant pattern or range will be under "Resistant Category" so, you can write Intermediate  range as Resistance.  and it may not write way to write it intermediate sensitive.

I mean it will be under "Resistant Category".

Best Regards,

Dr Anand

Dear Ali,

please find here an except from one of my papers (High prevalence of multiple-antibiotic-resistant (MAR) Escherichia coli in river bed sediments of the Apies River, South Africa) which you can get at:

http://link.springer.com/article/10.1007%2Fs10661-015-4879-6#/page-1

"An organism is said to be susceptible when the organism is inhibited when exposed in vitro to a concentration of a drug (high probability of therapeutic success); intermediate means that the organism is inhibited in vitro, but the therapeutic effect is uncertain; and resistant meaning that exposure results in a high likelihood of therapeutic failure (Rodloff et al. 2008)."

You can also look at "Susceptible, Intermediate, and Resistant – The Intensity of Antibiotic Action" which you can get at:

I hope this helps you

Thanks Dr Anand Prakash Maurya and 

many thanks to Akebe Luther King Abia . It answers my query to my full satisfaction.

This bug may be sensible in vivo by administering the highest possible dose of the antibiotic to the patient. In the end, the clinical improvement  counts.

Most of the in vitro studies consider intermediate into resistant category  

Intermediate means the bacteria is on the way to be resistant to the given dose. If the dose is increased then it tends to be sensitive as well.

According to CLSI, the “intermediate” category includes isolates with antimicrobial agent MICs that approach usually attainable blood and tissue levels, and for which response rates may be lower than for susceptible isolates. The intermediate category implies clinical efficacy in body sites where the drugs are physiologically concentrated (eg, quinolones and B-lactams in urine) or when a higher than normal dosage of a drug can be used (eg, B-lactams).

However, according to my knowledge, you have first to re-test your organism (by DDt) triple, before you determine it was "I" or not. I think it depends on the value of "I". If it was closer to the breakpoint of "Sensitive", it should considered Sensitive, otherwise   it should considered Resistant If it was closer to the breakpoint of "resistant".

Great regards

The sensitive means can treat by this antibiotic. The resistance means can not treat by this antibiotic. The intermediate means cannot treat by this antibiotic with a normal dose, however increase the dose remains effective. The newest definiton of intermediate resistance defined by EUCAST considered intermediate as resistant group.

According to the new changes in EUCAST 2019, the intermediate category is now consider as susceptible:

"I – Susceptible, increased exposure: A microorganism is categorised as Susceptible, Increased exposure* when there is a high likelihood of therapeutic success because exposure to the agent is increased by adjusting the dosing regimen or by its concentration at the site of infection."
