“…As early as late spring 1944, Delamater et al reported the first example of a sulfadiazine-resistant hemolytic Streptococcus causing disease that occurred at Keesler Field, Mississippi, a large Army Air Forces training center. Enzo et al confirmed that multiple classes of antimicrobial compounds (commonly at concentrations >100 μg/L) were detected in swine waste storage lagoons [ 33 ]. In addition, multiple classes of antimicrobial compounds were detected in surface and groundwater samples collected proximal to the swine and poultry farms.…”

Antibiotics have long been of great benefit for people, both in the medical treatment of human disease and in animal food where they improve the growth performance and feed utilization during animal production. Antibiotics as in-feed supplements affect all stages of pork production, including the gestation, nursing, growing, and finishing stages, although the effects show stage-dependent differences. However, the use of antibiotics in animal feed has become a worldwide concern. This review describes why sub-therapeutic levels of antibiotic additives in animal feed have become an integral part of animal feeding programs for more than 70 years, particularly in pork production. It also discusses the threat of the long-term use of sub-therapeutic levels of antibiotics in pork production. In recent years, the effectiveness of in-feed antibiotics has tended to decrease. This review analyzes this change from various perspectives. First, the equipment used at pig farms has improved dramatically and is more sanitary. Worldwide, more pig farms use pig farrowing crates, gestation crates, piglet nursery crates, flooring devices, piggery ventilation and cooler systems, automatic pig feeders, piggery heating equipment, and artificial insemination systems. In addition, scientists have replaced the use of antibiotics with organic acids, fermented mash, probiotics, prebiotics, minerals, oligosaccharides, enzymes, herbs/flavors, and protein/amino acids, and have improved management and husbandry techniques. In addition, animal welfare legislation has been aimed at improving the quality of the floors and living space, ensuring that animals have permanent access to fresh water, and setting a minimum weaning age. Finally, the prospects and the possibility of replacing antibiotics in pork production are described, in line with recent research results.

“…However, when sulfadiazine, an early short-acting sulfur antibacterial, was used in mass prophylaxis programs to prevent S. pyogenes tonsillitis and acute rheumatic fever (ARF) in military recruits in the 1940s, the clinical efficacy of this antibacterial was limited due to the presumed development of resistance (13,15,27,31,42) among some strains. Initial antibacterial susceptibility testing (AST) of S. pyogenes to sulfur antibacterials using a broth dilution method demonstrated that some strains were resistant (25,53); however, AST was in its infancy and no standardized reference methods existed at that time.…”

Is Streptococcus pyogenes Resistant or Susceptible to Trimethoprim-Sulfamethoxazole?

“…These authors give accounts of controlled trials in the American Services during the 1939-45 war, but it should be remembered that the subjects were practically all young healthy recruits, and that the organism responsible for the acute respiratory illnesses was usually the streptococcus. Subsequently doubt was cast upon the advisability of "mass chemoprophylaxis," as increasing numbers of sulphonamide-resistant streptococci were found in cases both in the Services and in the general population (Epidemiology Unit Number 22, 1945;Delamater et al, 1946;Wilson, 1946;Roberg, 1946;Damrosch, 1946;Johnson and Hartman, 1947). These authors thought that sulphonamide prophylaxis was ineffective and possibly dangerous.…”
