In recent years, swine streptococcus disease and edema disease have been on the rise. Farms in various regions, small and medium-sized retail households, occur frequently, and their morbidity and mortality rate are relatively high, causing serious economic losses to the breeding profession. The clinical experience and comprehensive prevention and treatment measures for the treatment of this disease over the past few years are described below for reference by peers. 1 Popular features 1.1 Streptococcus suis disease can be divided into acute septic type, meningitis type, subacute or chronic and new encephalomyelitis type, etc. Acute septic type mostly occurs in shelf pigs (growth fattening pigs), meningitis type Occurs in suckling piglets and weaned piglets. Subacute and chronic pigs have pathogenesis. Encephalomyelitis occurs mostly in gilts and pregnant sows. 1.2 Edema is also called enterotoxaemia, pink eye, and erythroderma. It is a systemic or local paralysis caused by a toxin produced by hemolytic E.coli. It is an acute, fatal disease of ataxia, and the fastest 1 to 3 hours. Slow but also over 2 days of death, the highest incidence of weaning pigs after weaning, the fastest mortality, mostly the first large incidence, after infection to other pigs in the same circle, the incidence of finishing pigs is relatively low, but there are also They are often ignored and cause death. 2 Causes Infectious, or immune failure, infectious, refers to a wide range of transmission, flies, mosquitoes, mice, humans are the source of infection. Immunity failure refers to inappropriate vaccine selection. Most farmers choose edema, streptococcus, enteritis, and two anti-vaccine vaccines in order to save money and time. The result is a low protection rate, which does not achieve the immune effect. Single vaccine should be selected. , cross-immunization, good effect, high protection rate. 3 clinical symptoms 3.1 Streptococcal disease Acute septic type, onset shelf pigs suddenly do not eat, high fever, hi lying, surface color changes, if misdiagnosed, it is difficult to treat. Meningitis type mostly occurs in suckling piglets and weaned piglets. The suckling piglets show stiff neck, head biased to one side, revolving to the ground again, turning to the ground, swimming in the extremities, without timely medication or improper medication, death The rate is quite high. Sub-acute or chronic piglets or finishing pigs are easy to diagnose and use. New encephalomyelitis type is most likely to be misdiagnosed and the best period of missed medications, resulting in paralysis of the rear sows of the sow until the final death. The peak incidence of the disease is in late autumn each year. The most dangerous is the sows with gilts and pregnant sows. . 3.2 Edema disease After the weaning, the piglet suddenly develops and has a fever for a short time. When it is found, the body temperature drops, the body is depressed, does not eat, spreads feet, is sensitive, touches screams, and the serious eyeball protrudes. It appears to fall out and the skin becomes purple and hard to breathe. , abdominal distension and a series of different symptoms. 4 Diagnosis According to the necropsy and serological tests can be confirmed. 5 Prevention measures Anti-stress, disinfection and immunization, and the addition of prophylactic drugs in feeds all play a preventive role. Now we combine clinical practice to highlight several diagnostic points and methods of medication. 5.1 Oedema Disease The same group of patients with mild or no disease, emergency vaccination, edema (single) 2 heads, and streptococcal disease, inoculated single seedlings (1). 5.2 Deoxycholic acid, moroxydine hydrochloride, and sulfadiazine sodium (double use) are preferred for the treatment of streptococcal disease in suckling piglets. 5.3 Encephalomyelitis-type streptococcal disease can be quickly diagnosed according to the sudden change of the season and the incidence of sows. Once the sow feed intake is reduced, the disease is immediately prescribed according to the disease. The drug of choice is high purity sulfamethoxazole. Pyrimidine sodium and high-purity astragalus polysaccharides were given in multiple doses for the first time. After the disease was controlled for 2 to 3 days, the cure rate was over 80%. 5.4 Piglet edema disease treatment points: The drug is the preferred sulfamonomethoxine sodium (single injection of normal dose); the combination of furazoxacin (fold) and furosemide combined with intramuscular injection can achieve a cure rate of over 80% for critical illnesses. The use of gentamycin is ineffective and often accelerates its death.
