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 ...
Bacterial or Fungal: All: Erosion at edges of fins: Improve water quality. Aquarium salt baths can treat mild cases. Use anti-fungal meds if visible film/spores/tufts. Use gram-negative antibiotics otherwise. Columnaris: Flexibacter bacteria: All: Cottony growth near mouth and or patches of grayish-white film on the body or fins. Improve water ...
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 .
Streptococcus iniae is a species of Gram-positive, sphere-shaped bacterium belonging to the genus Streptococcus.Since its isolation from an Amazon freshwater dolphin in the 1970s, S. iniae has emerged as a leading fish pathogen in aquaculture operations worldwide, resulting in over US$100M in annual losses.
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.

Bacteriophages and their host ranges are extremely specific for certain bacteria, thus, unlike antibiotics, they do not disturb the host organism's intestinal microbiota. [201] Bacteriophages, also known as phages, infect and kill bacteria primarily during lytic cycles.
A 20-year-old man could face a more than $13 million fine after breaking into an Oregon hatchery and pouring bleach into a rearing pond last week, killing nearly 18,000 baby salmon, according to ...
Pen-Strep (also known as penicillin-streptomycin) is a mixture of penicillin G and streptomycin that is widely used in mammalian cell culture media to prevent bacterial contamination. The solution contains 5,000 units of penicillin G (sodium salt) which acts as the active base, and 5,000 micrograms of streptomycin (sulfate) (base per milliliter ...
