A CDC infographic on how antibiotic-resistant bacteria have the potential to spread from farm animals. Antibiotic use in livestock is the use of antibiotics for any purpose in the husbandry of livestock, which includes treatment when ill (therapeutic), treatment of a group of animals when at least one is diagnosed with clinical infection (metaphylaxis [1]), and preventative treatment ...
There is an increasing prevalence of antibiotic resistance in S. pseudintermedius, specifically to methicillin, which makes it challenging to treat in humans. [44] [42] [41] Veterinary dermatologists are exposed to animals with skin and soft infections that commonly possess MRSP (methicillin‐resistant Staphylococcus pseudintermedius).
Increased antibiotic use is a matter of concern as antibiotic resistance is considered to be a serious threat to human and animal welfare in the future, and growing levels of antibiotics or antibiotic-resistant bacteria in the environment could increase the numbers of drug-resistant infections in both. [196]
The resistome was first used to describe the resistance capabilities of bacteria preventing the effectiveness of antibiotics . [4] [5] Although antibiotics and their accompanying antibiotic resistant genes come from natural habitats, before next-generation sequencing, most studies of antibiotic resistance had been confined to the laboratory. [6]
The development of antibiotic resistance in particular stems from the drugs targeting only specific bacterial molecules (almost always proteins). Because the drug is so specific, any mutation in these molecules will interfere with or negate its destructive effect, resulting in antibiotic resistance. [2]
Streptococcus canis is a group G beta-hemolytic species of Streptococcus. [1] It was first isolated in dogs, giving the bacterium its name. These bacteria are characteristically different from Streptococcus dysgalactiae, which is a human-specific group G species that has a different phenotypic chemical composition.
Antibiotic resistance—when bacteria change so antibiotics no longer work in people who need them to treat infections—is now a major threat to public health." [16] Each year, nearly 5 million deaths are associated with AMR globally. [7] In 2019, global deaths attributable to AMR numbered 1.27 million in 2019.
Two other mechanisms conferring unstable heteroresistance, resulting in an increased gene dosage of the resistance genes, are plasmid copy number increase and transposition of the resistance genes onto cryptic plasmids which increases in copy number. However, this mechanism is considered unstable, leading to a rapid return to susceptibility ...
