| Abstract: | To understand the pathogenic causes of weaning diarrhea in Yunnan province,we collected 210 feces and 60 drinking water,a total of 270 samples in 30 farms with weaning diarrhea and analyzed the virus and pathogenic bacteria.The results of the study showed that drinking water was sever polluted by pathogenic Escherichia coli,40 strains of pathogenic Escherichia coli were detected in drinking water,the positive rate was 66.7%,and 100 strains in feces with positive rate of 47.6%;10 strains of pathogenic Salmonella were detected in drinking water,the positive rate was 16.7%,and 24 strains in feces with positive rate of 11.4%,and were sensitive to imipenem.PCR amplified positive rates of porcine epidemic diarrhea virus (PEDV),porcine circovirous type 2 (PCV2),pseudorabies virus (PRV),classical swine fever virus (CSFV),porcine reproductive and respiratory syndrome virus (PRRSV) and porcine rotavirus (PoRV) in feces were 5.2% to 13.0%,and they were not detected in drinking water.By analyzing the causes of diarrhea in Yunnan province in weaned piglets analysis,understanding the specific causes of diarrhea in weaned piglets,the results provided a more reasonable and more realistic theoretical basis and experimental reference for prevention and control of the disease from the cause. |
