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 ...
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 .
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 ...
Strangles (also called equine distemper) is a contagious upper respiratory tract infection of horses and other equines caused by a Gram-positive bacterium, Streptococcus equi. [1] As a result, the lymph nodes swell, compressing the pharynx , larynx , and trachea , and can cause airway obstruction leading to death, hence the name strangles. [ 2 ]
The major host for A. equuli is horses and under physiological conditions, A. equuli is part of horses' mucosal microbiota and does not normally cause clinical symptoms and/or lesions. [3] However, when mucous membranes become compromised (wound penetration, ulcers/erosions) it allows for resident A. equuli to establish infection in the horses ...
In the laboratory, raccoons, cats, armadillos, skunks, and sea otters have been shown to be intermediate hosts of S. neurona. The opossum passes the parasite through feces. Horses contract EPM from contaminated feed or water. Horses cannot pass the disease among themselves; that is, one horse cannot contract the disease from another infected horse.

The bacteria can persist in water for up to 32 days when the hardness is 50 ppm or more. [2] Minerals are however essential for fish and the reduction or removal of such minerals in treatment for Columnaris would affect fish mineral uptake and thus affect: oxygen utilization, osmotic regulation, metabolic processes, among may other biological ...
