Our leftover medicines are spawning drug-resistant “bacterial monsters” that thrive inside sharks, scientists say. The finding suggests antibiotics such as penicillin
may be leaching into the environment and spurring drug-resistant bacteria to evolve and multiply in the oceans
.
Why is it bad to give animals antibiotics?
Using antibiotics in animals may
raise the risk of transmitting drug-resistant bacteria to humans
either by direct infection or by transferring “resistance genes from agriculture into human pathogens,” researchers caution .
Can sharks have antibiotics?
Results indicate that the combination therapy of
imipenem
(a carbapenem antibiotic) and vancomycin (a glycopeptide antibiotic) might be the most effective option to treat infections resulting from white shark bites, particularly in South Africa.
Do shark teeth have bacteria?
Abstract
.
Bacteria were cultured for the first time
from the teeth of a great white shark (Carcharodon carcharias). Isolates included Vibrio alginolyticus, Vibrio fluvialis, Vibrio parahaemolyticus, and other genera. All are common in the marine environment and some may be associated with wound infections in humans.
What organisms can be killed by antibiotics?
Antibiotics are chemicals that kill or inhibit the growth of
bacteria
and are used to treat bacterial infections. They are produced in nature by soil bacteria and fungi.
Do sharks get infections?
Sharks have only a few predators in the ocean, but a new study has found that

Why antibiotics should be banned?
Taking antibiotics too often or for the wrong reasons can
change bacteria
so much that antibiotics don’t work against them. This is called bacterial resistance or antibiotic resistance. Some bacteria are now resistant to even the most powerful antibiotics available. Antibiotic resistance is a growing problem.
What is the strongest antibiotic?
The world’s last line of defense against disease-causing bacteria just got a new warrior:
vancomycin 3.0
. Its predecessor—vancomycin 1.0—has been used since 1958 to combat dangerous infections like methicillin-resistant Staphylococcus aureus.
How do you treat shark teeth?
The way you handle shark teeth depends on the baby tooth. If it’s even a little loose, have your child
try to wiggle it several times a day to further loosen it
. In many of these cases, the baby tooth will eventually fall out on its own, and the permanent tooth will move into place.
