The cells of bacteria (prokaryotes), such as salmonella, differ from those of higher-level organisms , such as fish. Antibiotics are chemicals designed to either kill or inhibit the growth of pathogenic bacteria while exploiting the differences between prokaryotes and eukaryotes in order to make them relatively harmless in higher-level ...
Blooming cyanobacteria can produce cyanotoxins in such concentrations that they can poison and even kill animals and humans. Cyanotoxins can also accumulate in other animals such as fish and shellfish, and cause poisonings such as shellfish poisoning. Some of the most powerful natural poisons known are cyanotoxins.
Bactericidal antibiotics kill bacteria; bacteriostatic antibiotics slow their growth or reproduction. Bactericidal antibiotics that inhibit cell wall synthesis: the beta-lactam antibiotics ( penicillin derivatives ( penams ), cephalosporins ( cephems ), monobactams , and carbapenems ) and vancomycin .
Infection is usually associated either with swimming, preparing sea food, or with keeping or working with aquarium fish. [2] Infections of humans are rare due to the chlorination of water. [ 4 ] The bacteria penetrate the skin through trauma, usually from bites, injuries from fins, and penetration from foreign objects.
Antimicrobial use has been common practice for at least 2000 years. Ancient Egyptians and ancient Greeks used specific molds and plant extracts to treat infection. [5]In the 19th century, microbiologists such as Louis Pasteur and Jules Francois Joubert observed antagonism between some bacteria and discussed the merits of controlling these interactions in medicine.

Animal sources, especially cold-water fish, which are lower in mercury, are rich sources of omega-3 fatty acids. Two servings (3-4 ounces per serving) a week for an average adult is a recommended ...
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 ...
Most health claims on fish oil supplements are unfounded A 2023 study analyzed the labels of more than 2,800 fish oil supplements and found that 2,082 — nearly 74% — made at least one health ...
