The WHO Model List of Essential Medicines for Children (aka Essential Medicines List for Children [1] or EMLc [1]), published by the World Health Organization (WHO), contains the medications considered to be most effective and safe in children up to twelve years of age to meet the most important needs in a health system.
In agar and broth dilution methods, bacteria are placed in multiple small tubes with different concentrations of antibiotics. [14] 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]
Regions with low neonatal mortality include Europe, the Western Pacific, and the Americas, which have sepsis rates that account for 9.1% to 15.3% of the total neonatal deaths worldwide. This is in contrast with the 22.5 to 27.2% percentage of total deaths in resource-poor countries such as Nigeria, the Democratic Republic of the Congo, India ...
Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
The pH level of the agar must be between 7.2 and 7.4. Bacterial inoculum is prepared by diluting a broth culture to match a 0.5 McFarland turbidity standard, which is equivalent to approximately 150 million cells per mL.

Pregnancy increases the clearance of ampicillin by up to 50%, and a higher dose is thus needed to reach therapeutic levels. [25] [27] Ampicillin crosses the placenta and remains in the amniotic fluid at 50–100% of the concentration in maternal plasma; this can lead to high concentrations of ampicillin in the newborn. [27]
Acinetobacter species are widely distributed in nature, and commonly occur in soil and water. [11] Their ability to survive on moist and dry surfaces, as well as to survive exposure to various common disinfectants, allows some Acinetobacter species to survive in a hospital environment. [ 11 ]
Agar dilution is one of two methods (along with broth dilution) used by researchers to determine the minimum inhibitory concentration (MIC) of antibiotics. It is the dilution method most frequently used to test the effectiveness of new antibiotics when a few antibiotics are tested against a large panel of different bacteria. [1]: 149 [2]
