EMERGING THREAT TO HUMAN HEALTH - krishangurawariya - 08-17-2017
EMERGING THREAT TO HUMAN HEALTH FROM MULTI DRUG RESISTANCE MICROBES IN FOOD OF ANIMAL ORIGIN
[attachment=16729]
EMERGING PATHOGENS
Three concepts:
New:- not previously recognized to cause serious hazards
Evolving:- become more potent and thus causing number of outbreaks in a
wide geographic range
Emerging:- newly aroused
Resistance to Wonder Drugs
.Resistance is negating wonder drugs
.Antibiotics the miracle drugs of the 20th century no longer work as they once did.
1945 - Alexander Fleming claims that the misuse of penicillin could lead to the selection and propagation of mutant forms of bacteria which are resistant to the drug,
Many of emerging pathogens are resistant to antimicrobial agents
Limiting the choice for treatment (public health concern)
Common misuses of antibiotics
Taking when they are not needed: in viral infections
-When needed, taking incorrectly: stopping the medicine when one feel better , sharing or using someone else s medicine
Self prescriber
in countries with poor health care services use of broad spectrum antibiotics without prescription
use for non-therapeutic purposes e.g. growth promotion or improved production in livestock
Where Does Resistance Develop?
In populations of bacteria
Animal guts (including humans) are filled with live bacteria
The guts of animals, fed antibiotics in food and water, are filled with resistant bacteria
