Introduction of Veterinary Antibacterial Drugs

- Jan 30, 2018 -

Antibacterial drugs refer to a class of drugs that inhibit or kill bacteria and can be used to prevent and treat bacterial infections, including antibiotics and synthetic antibacterials. In veterinary clinical, antibacterial drugs are for the prevention and treatment of bacterial infections in animals. Antibacterial drugs are known as "animal antibacterial drugs." Penicillins, cephalosporins and sulfa antibiotic synthesis are commonly used in veterinary.


Broad-spectrum antibacterials VS narrow-spectrum antibacterials

Antimicrobial spectrum is the range of antibacterials that inhibit or kill pathogenic microorganisms.

Broad spectrum antibacterial drugs: inhibit or kill a variety of different types of bacteria and have a wide range of antibacterial, such as florfenicol, doxycycline and enrofloxacin. They not only have antibacterial activity against Gram-positive bacteria and Gram-negative bacteria, but also inhibit Mycoplasma, Chlamydia, Rickettsia and so on.

Narrow-spectrum antibacterial drugs: antibacterial range only act on a single species or a single genus. For example, penicillin and erythromycin only effective against Gram-positive bacteria, streptomycin and neomycin effective only against Gram-negative bacteria.


Why use antimicrobials in poultry breeding?

The ultimate goal of using antibacterials is to protect human health in poultry breeding. When the animal's immunity declines, the pathogenic microorganisms make them sick. Without timely treatment, the disease spreads easily in farmed animals, seriously affecting the health of animals, leading to reduced product quality and lower yields. Some animal diseases can also be transmitted to humans, such as Streptococcus suis, swine erysipelas and so on.


A timely and reasonable usage of antibacterial drugs could protect product quality, ensure the health of consumers and avoid economic losses.


Classification of antibacterial drug


(1) penicillins, such as penicillin, benzathine penicillin, ampicillin, amoxicillin.

(2) cephalosporins, such as cephalexin, ceftiofur, cefquinome oxime and so on.

(3) aminoglycosides, such as streptomycin, gentamicin, kanamycin, neomycin, spectinomycin and apramycin and so on.

(4) tetracyclines, such as chlortetracycline, oxytetracycline, tetracycline and doxycycline.

(5) Amide alcohols, such as florfenicol, thiamphenicol.

(6) macrolides, such as erythromycin, guitarmycin, tylosin, for the test, such as tricin.

(7) polypeptides, such as bacitracin, nosiheptide and so on.

(8) Lincosamines, such as lincomycin.

(9) pleuromutilin class, such as tiamulin.


Synthetic antibacterials:

(1) fluoroquinolones: ciprofloxacin, enrofloxacin, sarafloxacin, difloxacin, danofloxacin, marbofloxacin and so on.

(2) Sulfonamides: Sulfadiazine, Sulfathiazole, Sulfamethazine, Sulfamethoxazole, Sulfamonomethoxine, Sulfamonomethoxine, Sulfaquinoxaline, Sulfasalazine, Sulfadiazine, Sulfonamides Amidine, trimethoprim and so on.

(3) quinoxaline: olaquindox, mequindox, Quinocetone and so on.


Antibacterials play an important role in the prevention and treatment of livestock and poultry diseases. If had any further questions, please inquiry us.
