The Prevalence of Clostridium perfringens in Pigs with the Symptom of Diarrhoea in Hanoi and Surrounding Areas

Abstract

The study was undertaken to determine the prevalence and the role of  C. perfringens in pigs found with diarrhoea in Hanoi and some surrounding areas. The studied regions included: Gia Lam, Cau Dien, Ha Tay (old-established), Bac Ninh and Vinh Phuc. Results showed that the prevalence of identified C. perfringens in faecal samples of pigs with diarrhoea was 55.6%. The number of C. perfringens in faecal samples of pigs with diarrhoea increased signficantly compared to that of healthy ones. In 1 - 28 day-old piglets, the number of C. perfringens was 1.92 ± 0.08 x 10⁷ CFU/g compared to 1.74 ± 0.07 x 10⁵ CFU/g (increased 110.34 times). In 29 - 90 day-old pigs, the number of C. perfringens was 4.19 ± 0.61 x 10⁷ CFU/g compared to  2.88 ± 0.10 x 10⁵ CFU/g (increased 145.49 times) (P <0.001). There was no significant difference in the prevalence of  identified C. perfringens in the samples taken from the different  areas and age-groups (P > 0.05)
