Complexity of the aetiology of the suckling piglets diarrhoea

摘要

This review of the literature is characterising the aetiology of the diarrhoea of suckling piglets with reference to pathogenic bacteria and viruses, also including the influence of the unfavourable environmental factors. The laboratory investigations of faecal samples demonstrated the etiological importance of E. coli, not only those with haemolytic properties but also non haemolytic strains. The majority of E. coli strains of etiological importance belonged to pathotype EPEC. These strains produced one or several enterotoxins, being thermostable or termolable. They produce fimbrial antigens: F4, F5, F6 and F41. Strains of Clostridium perfringens cultured from the majority of faeces samples belong to type A. The Rotavirus type A, in comparison with TGEV and PEDV plaid the leading role in the multifactorial aetiology of suckling piglet diarrhoea. Concluding, exact definition of aetiology of piglet diarrhoea is at present not possible and requires further research. These results could eventually more precisely define, than it is possible at present, the passive prophylaxis of the diarrhoea of suckling piglets and a more adequate choice of drugs.
