All these features of antibiotics are a huge advantage but on the other hand, they have certain disadvantages. Overuse or misuse of antibiotic can cause side effects and can also make the pathogen resistant to the medicine. Some antibiotics kill the good bacteria in the body that are actually helpful in various life processes we carry out. In case of vaccines, the major advantage is the fact that vaccination prepares the immune system against the injected pathogen and of a similar pathogen happens to attack the body in future; it won’t be able to harm the body.
aeruginosa’s ability to mutate genetically and transform into different antibiotic-resistant strains, make it the most important bacteria species studied among patients suffering from CF. It’s ability to form a glycocalyx and prevent the host’s white blood cells to attach and phagocytize the pathogen also contributes to its importance of a pathogen. The formation of a biofilm communicates to the bacterial colony that it is being attacked by antibiotics and to mutate to adapt and survive. The mutation of the bacteria to form an alginate to protect it from environmental stresses as well as the ability to release powerful exotoxins to inhibit protein synthesis of the host’s cells add to P. aeruginosa virulence and ability to develop chronic lung infections in CF
Tn 4351 was originally isolated from bacteroides fragilis  . The transposon was successfully introduced into Cytophaga succinicans, Flavobacterium meningosepticum, Flexibacter canadiansis, Flexibacter strain SFI and Sporocytophaga myxococcoides by conjugation . Tn 4351carries two antibiotic resistance gene. One of the codes for resistance to erythromycin and clindamycin which is expressed in bactroides but not in E.Coli. The other gene codes for resistance in tetracycline and is expressed in aerobically grpwn E. coli, but not in anaerobically grpwn E. coli or in bacteroides.
Until recently, Zika has been only seen as a global health threat spread by mosquitos, and surely not as a remedy. however, some of the latest research tells us that this virus could be used to selectively infect and kill cancerous cells in the brains of fully grown humans. During their research, the researchers gave brain stem cancer patients injections with the modified zika virus. These injections were seen to have shrank aggressive tumours, yet left other brain cells
However Hahnemann said, we need some bacteria for our wellbeing. For examples, we need some bacteria in our gut to assist with digestion. Therefore he said, a microbe can cause a disease only when the body is susceptible to it. Strengthening the vital force Health is the balanced state of body, mind and spirit.
Thus, the result was the establishment of compulsory health laws which, as rationalized by activists like Henry Rumsey and John Simon, were for the interest of the population’s well-being. The first federal law relating to preventive health care measures was the 1813 Vaccine Act in the United States which also led to the establishment of the National Vaccine Agency. Others include the 1840 Poor Law medical services as well as the new Vaccination Act of 1867 in Britain. Although the laws were successful, like many other measures, it had faced oppositions.
Antibiotic medications have saved many people’s lives. Unfortunately antibiotics are no longer as effective in stopping pathogenic bacteria infection. Currently there is an antibiotic resistance crisis since may bacteria have become or are becoming resistant to all of the antibiotics developed. Instead of researching new antibiotics, which will continue to promote antibiotic resistance, antibiotic stewardship should be promoted specifically dealing with preventing infections, monitoring antibiotic prescription, and developing laboratory tests that provide accurate results faster. Hospitals need to reduce the infections contracted during patients stays in their facilities.
Genetic engineering so far has been widely successful, and has not shown any negative effects. It may seem easy to protest gene editing without thoroughly researching it, there are unfortunate people who urgently need this gene therapy to cure or withhold the growth of a deadly disease, so genetic engineering could be the
This injection causes the body to build up antibodies against the disease without actually getting the disease itself. Since antibodies are now present in the body, if the body is invaded by the germs that actually cause the disease, the immune system immediately sends antibodies to destroy the germs. Getting immunized is the best way to prevent spreading diseases. Since their corresponding vaccines were introduced, deaths cause by diseases such as polio, measles and tetanus have been greatly reduced. Since it has been witnessed that smallpox has been completely eradicated worldwide it gives man hope that other disease will be eliminated as well.
PHAR 100 Assignment 3 1. Antibiotics are a form of medicine that seek out and destroy the bacteria that make us feel sick. Antibiotics work great against bacteria, however they don’t work against viruses. Penicillin was the first antibiotic to be discovered by Alexander Fleming, and it was first used to treat infections. Essentially, these powerful medicines fight bacterial infections, and have the potential to save lives.
