Antimicrobials in poultry

Antimicrobial agents are essential tools for treating and controlling bacterial infections in poultry production. Veterinarians have a huge responsibility when using antimicrobials in poultry producing meat and eggs for human consumption. The term ‘judicious use’ of antimicrobials implies the optimal selection of drug, dose and duration of antimicrobial treatment, along with a reduction in inappropriate and excessive use as a means of slowing the emergence of antimicrobial resistance. The proper use of antimicrobials depends on the knowledge of interrelationships between bacteria, antimicrobial, host and consumer. The antimicrobial groups most commonly used in poultry are the betalactams, polypeptides, aminoglycosides and aminocyclitols, macrolides and lincosamides, florfenicol, tetracyclines, sulphonamides, quinolones and fluoroquinolones and ionophores.

I. INTRODUCTION Antibiotic stewardship and the judicious use of antibiotics as treatment for specific disease occurrences, rather than using sub-therapeutic doses for growth promotion, are well established concepts within the Australian poultry industry (Alfirevich, 2018). Intensive production systems however, are prone to increased stressors and large scale production does not always meet the individual needs of each bird. Optimising production performance within this...

There has been a lot of talk and discussions on the benefits of reducing or completely removing the use of antibiotics in livestock, particularly in poultry and swine, here in Asia and yet, so far, only a few countries have implemented regulations. As many antimicrobials are used in the livestock sector, studies have suggested that antimicrobial resistance (AMR) may be widely prevalent. Regulation on antimicrobial use is either weak or non-existent, complicated by sub-optimal enforcement and...

INTRODUCTION Salmonella and Campylobacter continue to be pathogens of concern associated with poultry and poultry products, which raise a public health issue globally (Antunes et al., 2016). As per the foodborne illness source estimation reports for 2016, Salmonella and Campylobacter are responsible for about 18 and 64% of poultry-related foodborne illnesses in the United States, respectively (IFSAC, 2018). With the increasing episodes of illnesses because of these pathogens,...

INTRODUCTION Consumption of poultry meat has increased significantly in the United States and currently ranks as the highest consumed among meat species (National Chicken Council, 2020). With increasing chicken meat consumption, greater number of broilers are being raised and processed. Foodborne pathogens Salmonella and Campylobacter are commensals in broiler gastrointestinal tract and, in most cases, do not cause any disease in the birds. Current poultry processing system...

INTRODUCTION Necrotic enteritis (NE) is a poultry illness caused by toxin-producing strains of Clostridium perfringens (CP) type A, type C and type G (1). NE is a pathology of global concern, with important consequences for flock productivity and economic viability (2). The total cost of NE outbreaks worldwide has been estimated to be over 2 billion dollars annually (3, 4). NE can present itself as a sudden increase in mortality or simply as a subclinical illness (2). CP is...

Introduction An increasing global population and food security needs have imposed a great pressure on poultry and livestock sectors to increase their production utilizing limited resources (1).Consequently, sub-therapeutic doses of antibiotics are being used widely in poultry as animal growth promoters and for prophylaxis (2). This is particularly true in low and middle income countries where poultry industries are playing an important role in their national economy...

1. Introduction In the Nigerian’ poultry value chain, live bird markets (LBMs) are essential to the farmers for the preferential sales and marketing of poultry and poultry products for human consumption [1]. The LBMs are typically in urban, peri-urban, and rural settings and typified by permanently placed pen-like structures in which the chickens can be temporarily housed until they are sold [2]. The LBMs bring together a variety of multi-farmed, multisourced, and...

The history of antibiotic use in poultry feed is quite old and in a very short period of time it gained a special identity as an antibiotic growth promoter (AGP). There is no doubt, this special name came from its proven effect on the growth performance. However, Health officials desperate to maintain the efficacy of...

by Sam Shafer As producers reduce antibiotic use, scientists examine new strategies to improve bird growth and health       Poultry scientists are investigating new ways to keep birds healthy and shift the poultry industry away from widespread use of antibiotics. Researchers are especially keen to improve antimicrobial strategies for organically raised chickens, which are not given antibiotics. According to a new paper...

INTRODUCTION Medicinal plants are reservoirs of bioactive compounds used by humans since early ages in traditional medicine for the treatment and prevention of diseases due to their therapeutic potential (Arun and Varsha, 2014; Dilfuza et al ., 2015). According to Oluwafemi et al . (2020); Adewale et al . (2020), there are over 500,000 species of medicinal plants identified globally which has led to the discovery of novel drugs or new pharmaceuticals used...

INTRODUCTION Virginiamycin (Vm) is a cyclic polypeptide antibiotic complex from Streptomyces virginiae of the streptogramin class of antibiotics. It is commonly used to treat infections from gram-positive organisms or as a growth promotant in cattle, swine, and poultry diets. The Vm complex consists of 2 major components, Vm factor m1 and s1, which act synergistically to prevent protein synthesis within bacteria (Cocito, 1979). It also has been suggested that antibacterial...

In the recent decades, the problem of antibiotic resistance is worsening fast, due to the misuse of antibiotics in human beings and in farm animals, and to the fact that it is difficult for the pharmaceutical industry to market new antibiotics. It is estimated that 1.2 million people worldwide die of antibiotic resistance every year....
