Some risk factors of Ascaris and Trichuris infection in Malaysian aborigine (Orang Asli) children.
A study on risk factors of soil-transmitted helminths was conducted in a highly endemic area. In all 205 children (95 boys and 110 girls) participated in this study. The overall prevalences of Ascaris, Trichuris and hookworm infection were 62.5%, 91.7% and 28.8% respectively. Only 22.4% of the children had a single infection either by Ascaris or Trichuris; 69.3% had mixed infection and the most...
متن کاملEffect of Ascaris suum infection on performance of fattening pigs.
Scientific investigations of production losses in pigs due to roundworms are rarely conducted in commercial farms, despite the fact that this information is needed to decide whether anthelmintic treatment is cost-effective or not. Therefore, the aim of our study was to compare performance in fattening pigs treated or not treated for Ascaris suum infections. Two Danish pig farms producing fatten...
متن کاملHeritability Estimates for Conformation Traits in Pigs
Data from 1006 pigs selected for breeding and subsequently scored at 22-24 weeks of age were used to estimate heritabilities for conformation traits. Front wrists, front pasterns, back hocks, back pasterns, front view, rear view and back shape were each subjectively scored by a single operator. For the individual traits heritability estimates ranged from high (0.42±0.09 for front pasterns) to n...
متن کاملHost age influence on the intensity of experimental Trichuris suis infection in pigs.
The impact of age-related resistance on the regulation of population dynamics of adult Trichuris suis was investigated in an experimental pig model. Helminth-naïve pigs varying in age from five weeks to four years were infected with T. suis to determine susceptibility to infection. Sows had a significantly lower establishment of adult T. suis worms compared with weaner pigs. Adult worm populati...
متن کاملAlbendazole and Praziquantel in Trichuris Infection
A randomized clinical trial was conducted to compare the effectiveness of albendazole alone and albendazole combined with praziquantel in the treatment of Trichuris trichiura infection. The drug regimens consisted of single dose of albendazole 400 mg (A1, n=34), 3 days of albendazole 400 mg daily (A3, n=34), 5 days of albendazole 400 mg daily (A5, n=35), single dose of albendazole 400 mg plus p...
