Abstract:
SummaryA novel repetitive DNA sequence in the sheep parasitic nematode Trichostrongylus colubriformis was cloned and sequenced. A l·1 kb repetitive sequence (Tc15) which hybridized with DNA from T. colubriformis but not with DNA from two other parasitic nematodes, Haemonchus contortus and Ostertagia circumcincta, or sheep was further characterized. Southern blot analysis showed that the repeat hybridized to a range of fragments in restriction digested T. colubriformis DNA and existed in multiple copy number tandem arrays. However, to define clearly the repetitive monomeric unit further screeni

Abstract:
This study aimed to identify the parasites that inhabit the digestive system of Sus scrofa scrofa from a commercial breeding facility in southern Brazil, and reports the first occurrence of Trichostrongylus colubriformis in wild boars. The gastrointestinal tracts of 40 wild boars from a commercial breeding facility were collected and individualized during slaughter in a cold-storage slaughterhouse. Out of this total, 87.5% were parasitized by the helminths Ascaris suum,Trichostrongylus colubriformis, Oesophagostomum dentatum and Trichuris suis. T. colubriformis presented a prevalence of 45%, m

Abstract:
Background: Trichostrongylus colubriformis is one of the most prevalent gastrointestinal nematodes of sheep in warm climates. In this nematode species, anthelmintic resistance (AR) has been reported, which has motivated the search for alternative methods to control it. One practice is to increase the immune response level through the selection of animals with natural resistance, such as Blackbelly sheep. The aim of this study was to investigate the response of IgA and IgG in serum and saliva and the level of cells involved in the acquired resistance in Blackbelly lambs after single artificial

Gastrointestinal nematodes (GINs) are ubiquitous in grazing small ruminants and cause significant costs due to production losses. Moreover, anthelmintic resistance (AR) is now widespread throughout Europe and poses a major threat to the sustainability of modern small ruminant livestock farming. Trichostrongylus colubriformis, an intestinal parasite of small ruminants, is the second nematode to Haemonchus contortus in terms of distribution and magnitude in several regions. The control of this helminth is traditionally achieved with the use of anthelmintic drugs, however due to regulations in or
