#New increase in antimicrobial use in animals in Denmarkantimicrobial usage in animals in Denmark continued to increase in 2013--mainly due to an increased use in pigs.
However antimicrobial use in pigs is still 12%lower than in 2009. In general livestock received very little of the critically important antimicrobials
which are used to treat humans. These findings appear in the annual DANMAP report from Statens Serum Institut and the National Food Institute Technical University of Denmark.
DANMAP is integrated the Danish antimicrobial resistance monitoring and research programme. In 2013 the total use of antimicrobials in livestock
and pets in Denmark was 4%higher than the previous year when measured in kilograms.
The increased consumption is attributed mainly to a 6%increase in the consumption of antimicrobials in pig production
Distributed by species pigs account for around 78%of antimicrobial use in 2013 cattle 10%aquaculture 3%poultry 1%fur animals 4
sows/piglets (9%)weaners (5%)and finishers (5%).This is primarily due to an increased consumption of pleuromutilins and tetracyclines
which are used for group medication. However the consumption in pigs is still 12%lower than in 2009
since Danish farmers stopped using antimicrobial growth promoters. It is crucial that we reverse the increase in consumption
if we are to tackle the problem of antimicrobial resistant bacteria senior researcher Yvonne Agersã¸from the National Food Institute says.
In 2013 antimicrobial consumption in poultry increased by 57%compared to the year before. This is partly because of the wet winter
which led to more illness and--as a result--an increased consumption of tetracyclines in turkeys.
An increased occurrence of diarrhea in broilers in 2013 can partly explain the increased consumption of penicillins which are an effective treatment against diarrhea.
Antimicrobial consumption in poultry is generally low compared to other species. It accounts for only 1%of the total use.
Continued low consumption of critically important antimicrobialsconsumption of critically important antimicrobials in animal production is still low.
The use of 3 kilos of cephalosporins in pig production is also low. However it does represent a significant increase compared to the year before
when total consumption of cephalosporins was 1 kilo. There has been a significant drop in consumption in cattle.
and cattle are treated with critically important antimicrobials only when absolutely necessary to help ensure these agents continue to be effective
In 2010 Danish pork producers introduced a voluntary ban on the use of cephalosporins where other effective treatment options are available.
In August 2014 the Danish Agriculture & Food Council encouraged cattle farmers to only use cephalosporins where this is the only effective treatment option.
Cephalosporins are used not in poultry production. Companion animals and horsesoverall the consumption of antimicrobials in the treatment of companion animals
and horses increased in 2013 compared to the year before. This increase was not due to an increase in the use of critically important antimicrobials as the consumption of both cephalosporins
and fluoroquinolones in 2013 was lower than the year before. However companion animals account for nearly 40%of the combined veterinary consumption of fluoroquinolones.
While it is unfortunate that we continue to see an increase in the total use in companion animals it is encouraging to see a drop in the use of antimicrobials that are critically important to humans.
The guidelines call for critically important antimicrobials to be avoided as much as possible Yvonne Agersã¸says. Facts about antimicrobial resistancetreatment with antimicrobials is intended to kill pathogenic bacteria.
Unfortunately antimicrobials also cause the bacteria to protect themselves by developing resistance to the type of antimicrobials that are used to treat them.
Resistant bacteria can be transmitted between humans and bacteria can infect each other with resistance. However resistant bacteria are poor at surviving
if antimicrobials are not present. Therefore it is important to have an overall focus on using as few antimicrobials as possible for the treatment of both animals and humans.
Bacteria know no borders therefore antimicrobial resistance in one country can cause problems outside of its borders.
As such the use of antimicrobials in both animals and humans is a global problem. Not all antimicrobials are the same.
Some are narrow spectrum and affect only individual groups of bacteria. They are used when you know which bacteria are causing the disease.
Others are broad spectrum and affect numerous groups of bacteria at the same time. They can therefore be used to treat a disease before knowing which bacteria are the cause.
Not all antimicrobials are equally important in the treatment of humans. WHO has declared a number of antimicrobials to be'critically important
'because they are the only or one of only a few antimicrobials which can be used to treat serious
or life-threatening infections in humans These types include carbapenems third and fourth generation cephalosporins fluoroquinolones and macrolides.

Much of the Staphylococcus aureus bacteria they carried were antibiotic resistant likely due to the use of drugs both to treat sick hogs
not only how persistence of this drug-resistant bacteria may impact the health of the workers themselves
In Europe the children of livestock workers have been treated for infections caused by a new livestock-associated strain of MRSA (methicillin-resistant Staphylococcus aureus) that doesn't match the more widely found community-or hospital-associated strains.
Evidence of persistent carriage of this new livestock-associated strain and its drug resistance has led to restrictions on the non-therapeutic use of antibiotics in livestock overseas.
Six of them persistently carried the multi-drug resistant kind of S. aureus while one persistently carried MRSA.

So what is the key to its'antimicrobial properties? Researchers at Lund University in Sweden have identified a unique group of 13 lactic acid bacteria found in fresh honey from the honey stomach of bees.
The bacteria produce a myriad of active antimicrobial compounds. These lactic acid bacteria have now been tested on severe human wound pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) Pseudomonas aeruginosa and vancomycin-resistant Enterococcus (VRE) among others.
When the lactic acid bacteria were applied to the pathogens in the laboratory it counteracted all of them.
Antibiotics are mostly one active substance effective against only a narrow spectrum of bacteria. When used alive these 13 lactic acid bacteria produce the right kind of antimicrobial compounds as needed depending on the threat.
It seems to have worked well for millions of years of protecting bees'health and honey against other harmful microorganisms.

#Synthesis produces new fungus-derived antibiotica fortuitous collaboration at Rice university has led to the total synthesis of a recently discovered natural antibiotic.
The laboratory recreation of a fungus-derived antibiotic viridicatumtoxin B may someday help bolster the fight against bacteria that evolve resistance to treatments in hospitals and clinics around the world.
As part of the process Rice organic chemist K c. Nicolaou and structural biologist Yousif Shamoo and their colleagues created
and tested a number of variants of viridicatumtoxin B that could lead to the simplified synthesis of a new generation of more effective antibiotics.
The work reported this month in the Journal of the American Chemical Society (JACS) focused on a tetracycline discovered in 2008 by scientists who isolated small amounts from penicillium fungi.
The new discovery belongs to a class of antibiotics known as tetracyclines for their distinctive molecular structure.
They proved potent in initial tests on Gram-positive bacteria so named for a staining technique to mark bacteria that are more susceptible to antibiotics than their Gram-negative counterparts.
The first tetracyclines discovered in the late 1940s ushered in a new class of powerful antibacterial agents to treat high-mortality diseases among them anthrax and plague as well as such bacterial infections as chlamydia syphilis and Lyme disease.
To find new weapons especially against superbugs that resist nearly all antibiotics synthetic chemists pursue the complex process of mimicking the structures of effective natural molecules as they build drug candidates atom by atom.
Tetracyclines are widespread antibiotics today but bacteria are building resistance to a lot of them Nicolaou said.
This new tetracycline is not plentiful in nature so the only way we can make it available to study by biologists for its potential in medicine is to synthesize it in the laboratory.
Three years of effort led the chemists working at Rice's Bioscience Research Collaborative to find a structure that not only matches that of natural viridicatumtoxin B
or surpass its antibiotic potency. Nicolaou who is known best for synthesizing the widely used anticancer drug taxol
and the chemotherapy agent calicheamicin said the complicated new molecule offered a challenge he couldn't resist.
Three was to use the technology we've developed to make analogs of it in the hope that we could find something simpler and yet better in terms of its biological and pharmacological properties.
In order to investigate the biological properties of our synthesized compounds we turned to the Shamoo laboratory for its expertise in the area of antibiotics and drug-resistant bacteria.
The results also suggested the possibility of making variants by modifying certain domains of the molecule to improve its overall pharmacological properties.
Our expertise in antibiotic resistance and his synthesis of viridicatumtoxin B and analogs were a perfect opportunity for us to work together on an important problem.
Nicolaou acknowledged it could be years--even decades--before an antibiotic derived from viridicatumtoxin B is available to patients.
and the tools developed through the process should prove valuable in the synthesis of other fungal tetracyclines.
and run to develop it into a drug he said. We have to worry about solubility biodegradation availability
In this month's print edition of the journal Angewandte Chemie Nicolaou laid out strategies for drug development to make
It's said that for a drug to be discovered a chemist has to make 10000 compounds on average he said.
It also means that it takes 12 to 15 years to develop a drug from the beginning to the end and costs between $1. 5 billion to $2 billion.

#It does need not always to be antibiotics: healthy pig breedingscientists found a way to reduce the application of antibiotics in pig breeding by using antimicrobial peptides.
The results of the study have just been published in the scientific online-journal PLOS ONE.
Researchers investigated the application of antimicrobial peptides (AMP) as substitutes for antibiotics in liquid sperm preservation.
Then they showed that two of the investigated AMPS suppressed bacterial growth in liquid preserved semen preparations if combined with a small amount of the antibiotic gentamicin.
which can lead to an increasing resistance against antibiotics. This causes big problems for breeders when using artificial insemination the method most commonly used in assisted reproductive technology in pig production worldwide.
The addition of antibiotics to liquid semen is required by law and facilitates an inhibition of bacterial growth.
However many types of bacteria quickly develop resistances to the usually applied antibiotics. Hence it is important to look for new antimicrobial alternatives.
