How can bacterial populations develop drug resistance and share that resistance with other bacteria?
Bacterial populations can develop drug resistance through mutations that make them less susceptible to antibiotics. They can also acquire resistance genes from other bacteria through mechanisms like conjugation, transformation, or transduction, allowing them to share resistance traits. This exchange of genetic material can lead to the rapid spread of drug resistance among bacterial populations.
What is meant by cross resistance in bacteria against two different antibiotics?
when two different antibiotics are taken simultaneously againt multi bacterial infections cross resistance in the bacteria results
A bacterial disease becomes difficult to cure when the bacteria?
develop resistance to antibiotics, making them less effective in treating the infection. This resistance can occur through genetic mutations or the acquisition of resistance genes from other bacteria through horizontal gene transfer. As a result, common antibiotics may no longer be able to kill the bacteria, leading to treatment failures.
What is cross resistance in bacteria for two different antibiotics?
"Bacterial cross-resistance happens when the two antibiotics that are being taken have very similar actions"
How have bacteria evolved resistance to penicillin?
natural selection, if a victim of a bacterial disease takes penicillin and the bacteria survives it is spread and reproduces, but those that don't have more resistance are either destroyed or have lower numbers
Which biological agent may be susceptible to antibiotic's but can develope resistance?
Bacteria are biological agents that are susceptible to antibiotics but can develop resistance through genetic mutations or acquiring resistance genes from other bacteria. Overuse or misuse of antibiotics can accelerate this process, leading to the development of drug-resistant bacterial strains.
Is toxic shock syndrome a bacterial infection?
Yes, Toxic Shock syndrome (TSS) is a bacterial infection where certain bacteria release toxins into the body. The bacteria responsible are staphylococcus aureus and streptococcus pyogenes.
The scientists responsible for the discovery of bacterial transformation is?
The scientists responsible for the discovery of bacterial transformation are Oswald Avery, Colin MacLeod, and Maclyn McCarty. They demonstrated that DNA is the genetic material that carries hereditary information in bacteria.
What morphological structure responsible for bacterial motility?
flagellla
How bacteria get mutated against certain drug?
The mutations are random and confer on some members of the bacterial population resistance to certain drugs and these members are the ones selected to survive and reproduce the next population of bacteria with the resistance to these certain drugs.
What enzyme is coded forin the chromosome of bacteria?
One common enzyme coded for in the chromosome of bacteria is DNA polymerase, which is responsible for replicating the bacterial DNA during cell division. This enzyme is essential for maintaining the integrity of the bacterial genome.
Can you take cipro for a cold?
No. Cipro ONLY works on bacterial infections. When you catch a cold or the flu you do not have a bacterial infection, you have a virus. No antibiotics work on any type of viral infections.
