Anthelmintic Resistance In Sheep Across Ireland And The Uk: A Literature Review Of The In Vivo Versus In Vitro Methods, Megan Tumulty

SURE Journal: Science Undergraduate Research Experience Journal

Background: The animal welfare and production consequences of gastrointestinal nematode infections, namely Nematodirus battus, on sheep are compelling. The control of gastrointestinal infections has been heavily reliant on the administration of anthelmintics since their introduction into mainstream use in 1960. However, their frequent and often excessive use has resulted in anthelmintic resistance being reported extensively in several gastrointestinal nematode species. The prevalence of anthelmintic resistance as well as the increase in the number of cases of multiple-drug resistance in nematode populations now poses substantial hindrance on the viability of sheep production systems. However, despite the threat N. battus poses …

Ocular sonography and echobiometry was performed in local nondescript sheep (N = 36) of different age group and in adult corriedale (N = 60), crossbred Fec B (N = 48), and Poll Dorset cross breed sheep (N = 48). Cornea, anterior, posterior lens capsule, and retinal rim appeared hyperechoic whereas aqueous, vitreous humor, and nucleus of lens were anechoic. Significant increase (P < 0.05) in all the echobiometric measurement of the ocular distance except central corneal thickness and retinal rim thickness was recorded in the older animals (2 year old) compared to values recorded in animals at one month of age in local nondescript sheep. Significant differences (P < 0.05) in few recorded ocular biometric measurements were also noticed among different sheep breeds. However, the difference in the various ocular biometric measurements between the right and left eyes was nonsignificant. The results of this study provide the base line information regarding the ocular echobiometry in sheep that are relevant to comparative ocular anatomy and can be useful for ultrasonographic evaluation of different ocular affections in sheep.

The aim of this study was to compare PCR tests for the detection of Mycoplasma agalactiae in sheep and goats. Samples obtained from sheep and goats in Turkey were tested to determine the presence of M. agalactiae. Mycoplasma culture and two direct PCR methods based on the uvrC gene and polC gene were compared with PCR of the 16S rRNA gene followed by denaturing gradient gel electrophoresis (PCR/DGGE) on DNA extracted from clinical samples (following culture enrichment). A total of 234 samples were examined: 9.4% and 13.2% were positive for M. agalactiae based on the uvrC gene and polC gene …
