Answer:
Legionella tends to form biofilms and infect other microbial cells as intracellular pathogens.
Explanation:
The Legionella genus of the bacteria is a group of gram-negative bacteria that can cause legionnaires disease.
The<em> Legionella pneumophila</em> is a species of this genus which can cause legion pneumonia. The bacteria lives in the freshwater and is resistant to chemical treatment like chlorine and the biocide treatment.
The reason for this resistance is since this species form a polysaccharide layer around the colony of the bacteria which is resistant to these treatments and also the bacteria prove parasitic to the protozoans which feed on these bacteria.
Thus, the selected option is the correct answer.
Given: Drug medications are often prescribed on the basis of body mass. the adult dosages of elixophylin, a drug used to treat asthma, is 6mg/kg of body mass.
To find: The dosage amount for a person weighing 160 lb.
Method: Unitary method of proportions
Solution:
First we'll convert the weight of person from imperial unit to metric unit.
1 pound = 0.45 kilograms
160 pounds = 0.45 x 160 = 72 kg
∴ The weight of person in kilograms is 72 kg.
Now, a elixophylin dosage of 6 mg is administered to 1 kg body mass.
For 72 kg body mass, dosage will be,
= 432 mg
∴ The person of 160 lb body weight will receive 432 mg of elixophylin dosage.
