Fasciolosis is an important parasitic zoonosis considered the most important helminth infection of ruminants in tropical countries. The aim of this study was to develop a PCR assay for the sensitive and specific detection of F. hepatica in formalin preserved sheep faeces. A 405-bp fragment of the cytochrome c oxidase subunit 1 gene of F. hepatica was amplified from stool samples of infected sheep. The PCR assay showed a detection limit of 20 pg of F. hepatica DNA. No cross-reactions were observed with samples containing coccidian oocysts or gastrointestinal nematodes eggs. Our PCR technique showed to be effective for specific detection of F. hepatica infections in sheep.

Paratuberculosis (PTB), primarily caused by subsp. (MAP), is a chronic infection that affects ruminants and is difficult to prevent, diagnose, and treat. Investigating how MAP infections affect the gut microbiota in sheep can aid in the prevention and treatment of ovine PTB.

Non-indigenous dung beetle (Coleoptera: Scarabaeoidea) species in North America are important contributors to ecosystem functions, particularly in pasture-based livestock systems. Despite the significant body of research surrounding non-indigenous (and often invasive) dung beetles in agricultural contexts, there has been minimal study concerning the impact that these species may have on indigenous dung beetle populations in natural environments. Here we examine the possible impact of the introduced dung beetle on indigenous dung beetle populations via use of indigenous mammal dung.

In this study, we examined the effects of different residual feed intakes (RFIs) on nutrient digestibility and the microbiota of the digestive tract of Dexin fine-wool sheep. Fifty 70-day-old Dexin fine-wool meat lambs were selected as the experimental group and fed in a single pen for 100 days. Based on their mid-term metabolic weight, 100-day average daily weight gain and daily feed intake, the male Dexin lambs were divided into a low-RFI group (13), a mid-RFI group (18), and a high-RFI group (11).

Understanding the composition of complex Escherichia coli populations from the environment is necessary for identifying strategies to reduce the impacts of fecal contamination and protect public health. Metabarcoding targeting the hypervariable gene gnd was used to reveal the complex population diversity of E. coli and phenotypically indistinct Escherichia species in water, soil, sediment, aquatic biofilm, and fecal samples from native forest and pastoral sites.

This study was designed to determine the prevalence of infections in sheep herds around tributaries in Pakistan and to evaluate the influence of potential risk factors. In total, 448 samples from 26 sheep herds were screened microscopically and then confirmed through polymerase chain reaction (PCR) amplification of the 18S SSU rRNA gene. Our result revealed that, out of 448 samples, 107 were found positive by microscopy and 77 positive by PCR, with prevalence rates of 23.
