Why is a larger zone of inhibition better than a small zone of inhibition?
A larger zone of inhibition means that the applied agent has either inhibited or killed the organisms that were spread on the plate and that those organisms are susceptible to that agent. In other words, a larger zone of inhibition means that the applied agent is more effective in killing/inhibiting the bacteria around it.
Benefits of cetylpyridinium chloride v chlorhexidine as an anti bacterial agent?
a. there is less staining of the teeth with cetylpyridinium chloride compared to the use of chlorhexidine b. efficacy of plaque inhibition of both chemicals (topical bacteriocides) depends on concentration in the mouthrinse c. chlorhexidine is a less stable solution: additional ingredients (e.g. fluoride) contained within some mouthrinse solutions may inactivate the plaque inhibitory agent
What is the difference between chemical and biological pest control?
In chemical control some kind of chemical is the killing agent, while in biological control the killing agent is a live organism. It may be a predetor or a bacteria or a paracite or fungi. While the definition is simple there is a multitude of implications. A chemical may be long lasting or degradable, but it never thinks nor can it reproduce. Both can have side effects which at times cause more damage then the original pest/disease they were meant to treat does.
Desirable characteristic of an ideal antimicrobial agent?
There are 6 factors that influence the efficacy of antimicrobial agents. They are, number and location of microorganisms, innate resistance of microorganisms, the potency of disinfectants, organic and inorganic matter, duration of exposure, and physical and chemical factors.
Agent that induces change in chromosome?
mutagen: ionizing radiation or chemicals, can also be called a mutagenic agent.

How to determine whether zone of inhibition is due to death of the bacteria or its inhibition?
If the compound you are testing is bacteriocidal, you will not be able to recover bacteria from the zone of inhibition. If the compound is only bacteriostatic, you should be able to recover bacteria from the zone of inhibition by scraping the surface of the agar and resupending the scrapings in sterile saline and then spreading an aliquot of the suspension on nutrient agar that does not contain the bacteriosttic agent.
What is an agent?
An agentive is the indication of the presence of an agent noun - for example, the presence of the suffix -er in the English language to describe the agent that performs the action of the verb.
What if a agar plate is isolated and antibiotic added and result is no growth or inhibition?
This is basically ANTIBIOTIC SENSITIVITY TEST, to test whether the given organism is RESISTANT(no zone of inhibition) or SENSITIVE( zone of inhibition) to the given antibiotic.Zone of Inhibition Testing is a fast, qualitative means to measure the ability of an antimicrobial agent to inhibit the growth of microorganisms.The effectiveness is based upon the size of zone of inhibition,diffusability of antibiotic,size of inoculum,type of media used.example: bacillus organism is inoculated with both PENICILLIN and AMPICILLIN ,zone of inhibition is absent in case of penicillin and present in case of ampicillin, this shows that ampicillin (sensitive) worked effectively when compared to penicillin.

Define the term behavior modifying drugs?
Any chemical agent used for the direct effect it exerts upon the central nervous system to modify thoughts, feelings, or actions.
How do you find antibiotic assay?
For determining the type of causal agent of infectious diseases and for checking their sensitivity to antibiotics and chemotherapeutic agents in vitro by means of the inhibition zone determination method. The antibiogram allows rational and selective chemotherapy. The test discs can be coated with chemotherapeutic agents, placed on the innoculated nutrient agar and incubated. The size of the inhibition zone is a measure for the effectiveness of the substances.
