A summary of 14 pathogenic bacteria commonly found in pig farms, and their applicable guidelines for the use of sensitive antibiotics:
1. Staphylococcus aureus (Gram-positive bacteria): porcine septic group disease, porcine respiratory and digestive system infection, porcine breast and endocardial inflammation;
Sensitive antibiotics: penicillin G; Followed by erythromycin, doxycycline, lincomycin, and sulfamethoxypyrimidine;
2. Streptococcus porcine (Gram-positive bacteria): Streptococcus porcine pneumonia, porcine purulent inflammation (such as breast, endocardial, joint and meningitis)
Sensitive antibiotics: penicillin G; Followed by erythromycin, cephalosporins, sulfamethoxypyrimidine, and doxycycline;
3. Porcine erysipelas (gram-negative bacteria): porcine dermatitis rash, porcine non-septic arthritis, warty endocarditis and septic type diseases;
Sensitive antibiotics: penicillins, followed by gentamicin or erythromycin, etc.;
4. E. coli porcine (gram-negative bacteria): yellow diarrhea in piglets, edematous disease in piglets, uterine inflammation in sows and postpartum no milk syndrome;
Sensitive antibiotics: ciprofloxacin, enrofloxacin, norfloxacin, gentamicin; Followed by streptomycin, neomycin, colistin sulfate, etc.;
5. Salmonella porcine (gram-negative bacteria): piglet paratyphoid fever, porcine necrotizing enteritis and septic disease;
Sensitive antibiotics: florfenicol, enrofloxacin, co-trimoxazole, tetracycline (such as oxytetracycline, doxycycline), streptomycin, etc.;
6. Pasteurella porcine (gram-negative bacteria): swine pneumonic disease, porcine laryngitis and pneumonia (lock throat wind)
Sensitive antibiotics: quinolones such as ciproxil, enrofloxacin, sulfadiazine sodium, doxycycline, oxytetracycline, penicillin, etc.;
7. Actinomycetes infectious pleural pneumonia in pigs (gram-negative bacteria): acute, hemorrhagic, fibrous, necrotizing pleural pneumonia in pigs;
Sensitive antibiotics: quinolones (ciprofloxacin, enrofloxacin), florfenicol, doxycycline, cephalosporins, Tylosins, spectinomycin, etc.;
8. Porcine treponemal dysentery: hematogenous dysentery in pigs;
Sensitive antibiotics: acetylmethoquine (dysentery net), followed by lincomycin, mycogen net, dimethimidazole, bacitracin, etc.;
9. Clostridium vicarinae (Gram-positive, anaerobic, toxin-producing bacteria): porcine necrotizing enteritis, red diarrhea, flatulence;
Sensitive antibiotics: dimethidazole, metronidazole, lincomycin;
10. Porcine bronchial septicae Bobacterium (gram-negative bacteria): porcine atrophic rhinitis, sneezing, nosebleeds;
Sensitive antibiotics: sulfamemethoxypyrimidine, oxytetracycline, doxycycline, mycogenin (0.1% potassium permanganate can be used to wash and disinfect the nasal cavity of pigs);
11. Mycoplasma porcine pneumonia: swine panting
Sensitive antibiotics: enrofloxacin, mycoplasmocin, lincomycin, tymarine, etc.;
12. Pig parasites (nematodes, mites, etc.):
Sensitive antibiotics: avermectin, ivermectin, levamisole, or organophosphates (pay attention to distinguish between internal or external use of the drug and related toxicity);
13. Porcine erythrocytes: punctate bleeding of pig skin, hemolytic anemia, jaundice;
Sensitive antibiotics: oxytetracycline, chlortetracycline, doxycycline, neoarsenic vanamine, etc.;
14. Pig arch body: sow reproductive disorder;
Sensitive antibiotics: sulfonamides such as methoxypyrimidine and other synergistic sulfonamides;
