Gastrointestinal tract (GIT) nematode infections have a significant negative impact on the well-being and productivity of animals. While it is common for a host to be co-infected with multiple species of nematode parasites simultaneously, there is a lack of effective tools to study the composition of these complex parasite communities. We describe the application of the "nemabiome" amplicon sequencing to study parasitic GIT nematode communities in captive wildlife at the National Zoological Garden, South African National Biodiversity Institute.

Background: Different areas of sheep infected with different types of parasites, all will cause serious harm to the local sheep, and the widespread use and repeated use of anthelmintics have produced different degrees of anthelmintic resistance (AR) in various regions. We re-investigated the infection of common parasites and AR of Gastrointestinal Nematodes (GINs) in sheep in Horqin Right Wing Front Banner, and first investigated the common parasite types and AR of GINs in sheep at other four areas in Hinggan league (city), China.
Results: A total of 1770 fecal samples were collected from 1 prefecture-level city and 4 counties in Hinggan league, in which the infection rate of Coccidia ranged from 83.

Due to their value as a food source, fiber, and other products globally, there has been a growing focus on the wellbeing and health of small ruminants, particularly in relation to anemia induced by blood-feeding gastrointestinal parasites like . The objective of this study was to assess the packed cell volume (PCV) levels in blood samples from small ruminants, specifically goats, and create an efficient biosensor for more convenient, yet accurate detection of anemia for on-farm use in agricultural environments for animal production optimization. The study encompassed 75 adult male Spanish goats, which underwent PCV testing to ascertain their PCV ranges and their association with anemic conditions.

Haemonchus contortus is a highly pathogenic gastrointestinal nematode that parasitizes the abomasum of cattle, sheep, and other ruminants. Long-term use of large quantities of ivermectin (IVM) to control H. contortus has resulted in the development of drug resistance.

Article Synopsis
- - The health and productivity of sheep infected with gastrointestinal helminths, particularly nematodes like Trichuris ovis, are negatively affected, prompting the need to understand host-parasite-microbiome interactions for better management strategies.
- - This study focused on the caecal microbiome of Kashmir Merino sheep, analyzing samples from both infected and non-infected individuals, revealing significant differences in microbial communities via 16S rRNA metagenomic analysis.
- - Findings showed that T. ovis infection leads to changes in the caecal microbiome, with an increase in potentially harmful bacteria and a decrease in beneficial ones, emphasizing the intricate relationship between hosts, parasites, and their microbiomes.
