As pathogenic micro organism evolve, antibiotic resistance is spreading, compromising our skill to regulate and deal with infectious ailments. Antibiotic Resistance completely illuminates this significant factor for healthcare pros, researchers, scholars, and policymakers. top investigators clarify what resistance is, the way it emerges, which human actions give a contribution, and the way to reinforce our defenses.

Our immune systems were strengthened by improvements in diet, and the frequency of some pathogen attacks was reduced by sanitation and water purification. For other pathogens, vaccines were developed that further decreased the overall burden of infectious disease. Insecticides provided local protection from being bitten by mosquitoes and other disease-carrying vectors. But our fear of pathogens was eliminated only by antibiotics. By taking pills for a few days, we could quickly recover from most bacterial diseases.
For example, some tumor viruses convert normal human and animal cells into tumor cells that continue to grow and divide after normal cells in the culture stop. In cases where normal cells cover the surface of a Petri dish and stop growing, tumor cells continue to pile on top of each other. The pile of tumor cells is called a focus. Foci can be seen and counted using a low-power microscope. The concentration of tumor viruses is then estimated by knowing the extent of dilution and volumes of virus samples applied to the Petri dish.
Duesberg’s ideas were immediately dismissed by the scientific community, sometimes with strong language, and NIH funding for his work was stopped. However, having a well-known scientist cast doubt on the link between HIV and AIDS provided impetus for South Africa to delay treatment of the virus. Delay is thought to have been costly, in part because South Africa was experiencing an epidemic of tuberculosis,39 a disease that is exacerbated by infection with HIV. ”40 Duesberg emphasized that it had not been possible to detect the virus, provirus, or viral RNA in all cases of AIDS (postulate 1).
