Sewage sludge and liquid pig manure as possible sources of antibiotic resistant bacteria
by Hölzel, C. S., Schwaiger, K., Harms, K., Küchenhoff, H., Kunz, A., Meyer, K., … Bauer, J. (2010). 2010 Environmental Research 110: 318-326

Age: Not stated;
Summary:
In this study, liquid pig manure (n=305) and sewage sludge (n=111) – used as agricultural fertilizers between 2002 and 2005 – were investigated for the presence of Escherichia coli, Enterococcus faecalis and Enterococcus faecium. Bacteria were tested for their resistance against 40 chemotherapeutics including several “reserve drugs”. E. coli (n=613) from pig manure were at a significantly higher degree resistant to streptomycin, doxycycline, spectinomycin, cotrimoxazole, and chloramphenicol than E. coli (n=116) from sewage sludge. Enterococci (Ent. faecalis, n=387, and Ent. faecium, n=183) from pig manure were significantly more often resistant to high levels of doxycycline, rifampicin, erythromycin, and streptomycin than Ent. faecalis (n=44) and Ent. faecium (n=125) from sewage sludge. Significant differences in enterococcal resistance were also seen for tylosin, chloramphenicol, gentamicin high level, fosfomycin, clindamicin, enrofloxacin, moxifloxacin, nitrofurantoin, and quinupristin/dalfopristin. High rates of (multi-) resistant bacteria in pig manure emphasize the need for a prudent – cautious – use of antibiotics in farm animals.

In Significant Impact Groups: Pathogen management \ Prudent use AB
Species targeted: Other; Sheep;
Age: Adult;
Summary:
In small ruminants, management tools for the control of mammary infections must be rethought, taking into account their animal specificities as well as management, equipment or work organization. The study integrated the inputs of observation, as a central element of the work of breeders and advisors, and various innovative technological solutions or automated recordings now available or in development as diagnostic tools (molecular bacteriology, cell counts, infrared spectra, clinical examination of the udder and the teat) and in terms of milking ability and milking conditions (use of milk kinetics recordings or vacuum fluctuations and thermography). In a context of antibiotics use reduction, criteria for the selection of animals to be cured (or culled) have been proposed. New phenotypes have been explored for a better understanding of the risk factors associated with milking. Finally, after studying the genetic progress and economic impact, the inclusion of new traits in selection schemes was carried out (somatic cell counts) or proposed to improve the resistance of animals to mammary infections.

Summary:
Soil is one of the biggest reservoirs of microbial diversity, yet the processes that define the community dynamics are not fully understood. Apart from soil management being vital for agricultural purposes, it is also considered a favorable environment for the evolution and development of antimicrobial resistance, which is due to its high complexity and ongoing competition between the microorganisms. Different approaches to agricultural production might have specific outcomes for soil microbial community composition and antibiotic resistance phenotype. Therefore in this study we aimed to compare the soil microbiota and its resistome in conventional and organic farming systems that are continually influenced by the different treatment (inorganic fertilizers and pesticides vs. organic manure and no chemical pest management). The comparison of the soil microbial communities revealed no major differences among the main phyla of bacteria between the two farming styles with similar soil structure and pH.

Passive immunisation, an old idea revisited: Basic principles and application to modern animal production systems by Hedegaard C.J. and P.M.H. Heegaard

Age: Adult;
Summary:
Immunisation by administration of antibodies (immunoglobulins) has been known for more than one hundred years as a very efficient means of obtaining immediate, short-lived protection against infection and/or against the disease-causing effects of toxins from microbial pathogens and from other sources. This review highlights a number of examples on the use of passive immunisation for the control of infectious disease in the modern production of a range of animals, including pigs, cattle, sheep, goat, poultry and fish. It is concluded that provided highly efficient, relatively low-price immunoglobulin products are available, passive immunisation has a clear role in the modern animal production sector as a means of controlling infectious diseases, importantly with a very low risk of causing development of bacterial resistance, thus constituting a real and widely applicable alternative to antibiotics.

Finding alternatives to antibiotics by Allen, H.K., Trachsel, J., Looft, T. and T.A. Casey 2014 Annals of the New York Academy of Sciences 1323: 91-100
In Significant Impact Groups: Prudent use AB \ Veterinarian
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep;
Age: Adult;
Summary:
The spread of antibiotic-resistant pathogens requires new treatments. As the rate of development of new antibiotics has severely declined, alternatives to antibiotics must be considered in both animal agriculture and human medicine. Products for disease prevention are different from those for disease treatment, and examples of both are discussed here. For example, modulating the gut microbial community, either through feed additives or fecal transplantation, could be a promising way to prevent certain diseases; for disease treatment, non-antibiotic approaches include phage therapy, phage lysins, bacteriocins, and predatory bacteria. Interestingly, several of these methods augment antibiotic efficacy by improving bacterial killing and decreasing antibiotic resistance selection. Because bacteria can ultimately evolve resistance to almost any therapeutic agent, it is important to continue to use both antibiotics and their alternatives judiciously.

Summary:
The widespread use of antibiotics in animals is causing concerns about the growing risk for development and the spread of antibiotic-resistant bacteria. Antibiotic consumption is higher in animals than in humans as reported in a joint publication of EFSA (European Food Safety Agency), ECDC (European Centre for Disease Prevention and Control), and EMA (European Medicines Agency) using data from 2011 and 2012. Both in humans and animals, positive associations between the consumption of antibiotics and resistant bacteria are observed. Responsible use of antibiotics in humans and animals should therefore be promoted. In this paper some general aspects of antibiotic resistance such as microbiological versus clinical resistance, intrinsic versus acquired resistance, resistance mechanisms, and transfer of resistance are briefly introduced.

Species targeted: Pigs;
Age: Young;
Summary:
Colistin is still often used outside the European Union as antibiotics to improve animal performance and health. Because first signs on antimicrobial resistance for colistin are seen, the scientific world is urgently looking for replacement of colistin as well as to find substitutes for zinc oxide in the European Union. Hops, known for their interactions with microbial cell structures, can offer a solution. This article describes and benchmarks hop extracts (β-acids) for that purpose, and came to interesting findings. When applied in nutrition for piglets, they observed improved performance (daily weight gain, daily feed conversion ratio), mainly by improved nutrient digestibility and intestinal health.

Summary:
Salmonella is classified by European authorities as a major coloniser in pigs and poultry, causing food poisoning after the consumption of meat. Alkaloids derived from plants, can be biochemically derivatized to quaternary benzo(c)phenanthridine alkaloids, that is able to kill Salmonella, and this way sanitising the meat. The main mode of action is based on maintaining gastrointestinal integrity, blocking Salmonella and other pathogens from entering the bloodstream and causing infection. The legal status of the quaternary benzo(c)phenanthridine alkaloids can be discussed, but opens the way to innovative interaction at the level of food quality and safety.

Age: Not stated;
Summary:
Pathogen colonisation in livestock can harm animal health, as well as subsequent human health after consumption of animal derived proteins (pork, poultry, beef, eggs, milk). The authors tested a portfolio of plant based essential oils on major microbial pathogens with clinical importance in animals (and humans), such as E. coli O157:H7, Salmonella Typhimurium, Staphylococcus aureus and Listeria monocytogenes. The results indicate that most of them show good potential in the treatment of these kind of infections, and leaves room for application in livestock production. Most plant based essential oils are pure compounds and tested in the laboratory ex-animal. For application in the field, the farmer has to decide on cost-effectiveness and on what’s available in the market at reasonable prices.
