After the required incubation period, when an even lawn of growth is distinctly visible, the MIC value is read where the pointed end of the inhibition ellipse intersects the side of the strip. Etests can be used as an alternative method to determine the minimum inhibitory concentrations of a wide range of antimicrobial agents against different ...
For some water systems a weekly dip slide test is recommended. For multiple tests the incubation period and temperature should be the same each time a new sample is assessed. Bacteria present in the sample liquid will grow and form colonies. A bacterial reference chart is used to determine the number of bacteria in the sample.
Whether a bacterium is sensitive or not is determined by visual inspection or automatic optical methods, after a period of incubation. [5] Broth dilution is considered the gold standard for phenotypic testing. [14] The lowest concentration of antibiotics that inhibits growth is considered the MIC. [5]
The terms "intrinsic incubation period" and "extrinsic incubation period" are used in vector-borne diseases. The intrinsic incubation period is the time taken by an organism to complete its development in the definitive host. The extrinsic incubation period is the time taken by an organism to develop in the intermediate host. [citation needed]
Experts say vehicle-based attacks are simple for a 'lone wolf' terrorist to plan and execute, and challenging for authorities to prevent.
In animals, the process involves a sperm fusing with an ovum, which eventually leads to the development of an embryo. Depending on the animal species, the process can occur within the body of the female in internal fertilization, or outside in the case of external fertilization. The fertilized egg cell is known as the zygote. [2] [5]
