Diagnosis, Prevention And Treatment Of Streptococcus Suis Infection Of A Pig Farm

Swine streptococcus is a kind of Gram-positive pathogens, which can be divided into35differentserotypes:1-34type and1/2type according to their capsular polysaccharide. Swine Streptococcus2（SS2）caused the strongest and full range affection. In addition, there are a lot of not typing ofStreptococcus suis. SS2is one of the main pathogenic bacteria causing Swine streptococcosis.Swine streptococcosis caused by SS2is one of the most important influence for pig farmingindustry in the world, which not only can cause pneumonia, arthritis, lymphadenitis, but also canthrough the blood-brain barrier affect pig central nervous system, cause meningitis, sowabortion.It brought huge economic losses to farmers. While SS2is also a important zoonoticpathogenic bacteria,it is a national second-class animal disease. it can cause people arthritis,meningitis, endocarditis, even to death.Currently domestic swine disease popular features is very complex, viral disease such as CSF、PRRS, PCV-2, PR, TGE and so on. Bacteriosis such as Swine streptococcosis, Swine haemophilusdisease, Porcine contagious pleuropneumonia, Swine pasteurellosis, Swine asthma, Colibacillosisand Swine paratyphoid. As well as some nutritional and metabolic diseases such as White muscledisease, Salt poisoning, Mycotoxin poisoning and so on. On the one hand the prevalence of thedisease is more generally. On the other hand because of breeding technology, bio-security andother factors led to mixed infections disease is becoming more popular new features of swine.ForSwine streptococcosis it is great practical significance for veterinarians and participants on thefirst-line to rapid diagnosis and proper to make the best prevention programs to researchdevelopment of character.The theses is select one thousand fattening pig farm in Changchun where outbreaks the Swinestreptococcosis for study, Through epidemiological analysis,28cases for clinical diagnosis,laboratory diagnosis and proposed epidemic prevention and control program for farm base onhomemade clinical medication film susceptibility to experimental. Summary:the outbreak of swineStreptococcus suis,85%of the infected pigs behave high fever,breathing difficμLties andclaudication.80%of the infected pigs who will appear cyanosis,78%of the infected pigs submandibμLar lymph nodes, inguinal lymph nodes, hilar lymph nodes are swollen several times,congestion hemorrhage, kidney swollen congestion, bleeding patches,pericardium have exudate,endocardium hemorrhage, lung congestion symptoms, liver congestion enlargement and tunicamucosa flushing and gastric bleeding lesions, intestinal hyperemia. The incidence of farm is25%and40%fatality rate. Then carry out control measures on the SS incidence of farms, by improvingthe rearing environment, comprehensive treatment, symptomatic treatment and other measures, aweek after the number of new cases are significant reduce, the status of the disease under control.
