The dynamics of genetically marked Ascaris suum infections in pigs.
SUMMARY The genotypes of both host and parasite may influence the outcome of parasitic infections, but few attempts have been made to quantify the effect of parasite genotype on macroparasite infections of socio-economic importance. We examined variation in particular traits during the infection in pigs with the parasitic nematode Ascaris suum. We infected 26 pigs with mixtures of equal proport...
متن کاملIntraocular IgE antibody induced in guinea pigs with Ascaris suum larvae.
The systemic and local (intraocular) IgE antibody responses to infective and heat-killed Ascaris suum larvae were examined in guinea pigs. IgE antibody, demonstrated by the 6-day P-K test, was found in anterior chamber fluid following primary intravitreal injection of live second-stage A. suum larvae and in some instances occurred when no serum P-K activity was demonstrable. No intraocular IgE ...
متن کاملEffect of papaya latex against Ascaris suum in naturally infected pigs.
An experiment was carried out to investigate the anthelmintic activity of papaya latex (Carica papaya) against natural infection of Ascaris suum in pigs. Sixteen naturally infected pigs were, on the basis of faecal egg counts and body weight, allocated into four groups, each of four pigs. Three groups (groups B, C, and D) were given papaya latex per os at dose levels of 2, 4, and 8 g of papaya ...
متن کاملAscaris suum
The nucleotide sequences of the mitochondrial DNA (mtDNA) molecules of two nematodes, Caenorhabditis elegans [13,794 nucleotide pairs (ntp)], and Ascaris suum (14,284 ntp) are presented and compared. Each molecule contains the genes for two ribosomal RNAs (+rRNA and 1-rRNA), 22 transfer RNAs (tRNAs) and 12 proteins, all of which are transcribed in the same direction. The protein genes are the s...
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...
