1 Background of the case study
John, an 88 years aged resident is facing itching and redness in his right eye after medical
investigation it was diagnosed the reason behind the eye problem was conjunctivitis
infectious. The issue John was facing was red and swollen eye and a sticky and infected
white discharge from the eyes. Threat increased when Mary also got the infections in her
eyes. This was a spreading infections and doctor recommended gentamicin eye drops and
some cautions to prevent the infections to spread to others (Grossman, 2013).
1.1 What is an infectious conjunctive?
Conjunctiva can be understand easily as the translucent slimy crust or shell lining on the
outer or frontier surface of the eyelids and the anterior surface of the eye ball. This infection
can be spread by the bacteria or microorganisms that causes the thick, mucous discharges
from the infected eyes or sometimes results in the red or pink eyeball anterior (Boustcha,
1995).
1.2 Which of four micro-organisms is more likely to cause infections in the eyes of John? Legionella Pneumophila
Legionella Pneumophila is not responsible to spread the infectious conjunctivitis in the
eyes of John. Legionella Pneumophila is liable to spread the Legionellosis infections and
Pontiac fever due to breathing in the water contains the bacteria in the droplets.
 Plasmodium P. ovale
No, Plasmodium P. ovale is not responsible to cause the eyes infection in the human beings but

this spice of parasitic protozoa is responsible to spread the infection of tertian malaria widely in
the human being and they are mostly responsible to spread the bacteria of malaria (Bullock,
2017).
 Adenovirus
Yes they can cause the conjunctivitis but not The common spices spreading the common
but dangerous disease to the human being are Adenovirus viruses. These viruses are
responsible for causing range of illness like sore throat, bronchitis, and pink eye problems
known as the conjunctivitis (Lehner, 2012).
 Staphylococcus aureus
The highly responsible microorganism to spread the infectious conjunctivitis are
Staphylococcus aureus, they are the acute bacteria causing the red eye, itching and thick
whites discharge from the eyes. They are wide spreading bacteria due to poor hygiene
habits of the people even by hand to eye contact and even spread to the others by contact
(Norris & Lalchandani, 2018).
2 Mechanism of action and adverse reactions
2.1 Describe the mechanism of action of gentamicin?
Gentamicin is used to cure the various types of bacterial infections as the antibiotic droplets.
The dose of the gentamicin can be given though the injections to direct muscles and some
time as droplets to use topical outside of the eyes. It was approved in 1964 for medical use.

Mechanism of gentamicin is based on the binding of the 30S subunits. These subunits are
prevailing in the bacterial ribosome. On the primary level the mechanism actions starts
through the ablating the ribosome to proper transfer RNA and the proper interactions of RNA
messenger. It directly affects the production of bacteria and prevents the infection spreading
by killing the infectious bacteria (Ringdal, 2019).
2.2 Write two adverse reactions of this drug?
Gentamicin an antibiotic dose cause less affecting issues to high affecting issues to the human
body. Major two reactions that affects adversely using the gentamicin drug are
 Nephrotoxicity that is damage to kidney
 Ototoxicity that is hearing and ear disorders
